    ABSTRACT: Mycosis fungoides (MF) is the most common and one of the least aggressive forms of cutaneous T-cell lymphoma. Several studies have demonstrated the influence of human leucocyte antigen (HLA) genes on the susceptibility of MF, highlighting the importance of certain alleles but, until today, no studies have evaluated the relationship between HLA alleles and the prognosis of patients with MF. The aim of this retrospective cohort study was to evaluate the polymorphism of HLA class I and class II alleles in a group of 46 MF Caucasian patients, looking for their influence in susceptibility and prognosis of the disease. Study population included a case-cohort sample of 46 Caucasian patients with MF that, between 1993 and 1997, underwent HLA class I and II genomic typing. All patients were diagnosed and followed up from 1977 to 2012 (mean follow-up of 11 years) and they were divided into three groups according to the evolution of the disease. Molecular typing at low-resolution level revealed that HLA-A*24, A*68, A*69, B*35 and DQB1*05:02 alleles were involved in susceptibility to MF. Correspondence analysis underlined that long-lasting remission was characterized by HLA-A*24 and HLA-A*25 alleles, frequent relapse by HLA-DRB1*01, DQA1*01:01, DQB1*05:01 alleles and death by HLA-A*68, HLA-B*08, HLA-B*35, HLA-C*03 alleles. This study suggests that the prognosis of MF patients is not only correlated with clinical/pathological/serological/immunological variables but it also relies on specific HLA alleles.

    ABSTRACT: A newborn's skin may exhibit a variety of changes during the first weeks of life, and rashes are extremely common in the neonatal period, representing a significant source of parental concern. In particular, a variety of skin eruptions can present as pustules. Most of them are innocuous and self-limiting, while others can be the manifestation of an infectious disease or even indicative of serious underlying disorders. Transient neonatal pustular melanosis is an uncommon vesiculopustular rash characterized by small pustules on a non-erythematous base, noted at birth or during the first day of life, without systemic symptoms. The lesions rupture spontaneously, leaving hyperpigmented macules that usually fade within few weeks. Clinical recognition of this disease can help physicians avoid unnecessary diagnostic testing and treatment for infectious etiologies because no specific therapy is recommended. The clinical aspect and time of onset are generally sufficient to make the correct diagnosis. Nevertheless, peculiar clinical presentations may require additional work-up to rule out life-threatening conditions, and dermatological consultation and histological examination are required for the final diagnosis. Conclusion: We report an exceedingly unusual presentation of transient neonatal pustular melanosis, suggesting the importance of a systematic diagnostic approach to allow a confident recognition of this benign condition.

    ABSTRACT: Pityriasis lichenoides (PL) is a uncommon, acquired disorder of unknown etiology characterized by a wide spectrum of clinical manifestations ranging from localized to generalized forms, including forms with intermediate and overlapping characteristics. In childhood generalized forms are more frequent and characterized by frequent relapses. Phototherapy with narrow band UVB (311nm)(NB-UVB) is a well-known efficacious and safe treatment, which makes it particularly suitable for the treatment of pediatric skin diseases, including psoriasis, atopic dermatitis, vitiligo, scleroderma. The current knowledge about its use for PL, especially in pediatric patients are limited but encouraging. We present five cases of PL pediatric patients resistant to common therapies treated with NB-UVB phototherapy with remission of the disease.

    ABSTRACT: Several factors hamper the clinical and histologic diagnosis of panniculitis. Clinically the patients tend to present with erythematous subcutaneous nodules with quite a monoto¬nous appearance, without additional symptoms. Histopathologically, as the subcutaneous fat re¬sponds to a variety of insults in a limited number of forms, there are sometimes subtle pathologic differences among the conditions. Although the biopsy plays a critical role in the diagnostic process of a panniculitis, a series of prerequisites must be met in order to obtain as much information as possible from this procedure. If the biopsy is inadequate, i.e., does not include sufficient subcutaneous fat or the site of sampling site/biopsy timing is wrong, histopathologic assess¬ment is limited and the correct diagnosis may be delayed and further sampling may be required. This article introduces the reader to the field of panniculitides under the histopathologic perspective through a brief description of the normal histology of subcutaneous fa. I also includes the definition of the types of fat necrosis, role of biopsy of panniculitis and its rules and pitfalls, up to a microscopic approach of a slide.

    ABSTRACT: A clinical approach to the vexing problem of diagnosis of panniculitis is traced in this paper, in order to obtain from the clinical findings, history and laboratory data of the patient useful, detailed and precise information, essential to address dermatologists to a specific clinical diagnosis of panniculitis. This approach is created in the same way as when a dermatologist faces any other dermatological disease, be it inflammatory or neoplastic. A common behavior in case of panniculitis is in fact just to take an adequate biopsy and wait for the pathologist report. This is indeed a limitation both for the dermatologist and above all for the pathologist, who is in tremendous need for detailed clinical information before signing his report. The most common types of panniculitides, taking into account their main clinical diagnostic criteria, will be considered. In particular, Erythema Nodosum, Panniculitides in Sarcoidosis, Pancreatic Panniculitis, Lupus Panniculitis, Erythema Induratum/Nodular Vasculitis and Weber-Christian Panniculitis/Rothman-Makai Pannicultis will be analyzed. Every chapter will consider general criteria (epidemiology, age and gender, distribution of the lesions, laboratory findings) and specific findings (characteristics of the lesions, i.e. redness, pain, tenderness, evolution, ulceration, sites of involvement) as well as comorbidities and systemic signs and sympthoms. Detailed analysis of the general criteria integrated with the specific findings will allow the clinicians to reach a clinical diagnosis with a high degree of confidence.

    ABSTRACT: Aim of this work was to define the histopathological features of post-surgical panniculitis. Dermal and hypodermal changes will be analyzed in detail, to understand the cascade of events that characterize the tissue response to surgical trauma. Cutaneous re-excision specimens of cases of basal cell carcinoma, squamous cell carcinoma, and melanoma consecutively seen from January 1, 2011 to June 30, 2011 at the Department of Dermatology, University of Pavia, were included in this study. Only the cases in which the first surgical procedure included the subcutaneous fat, were considered. In addition, the time elapsed from the first surgical procedure and the re-excision had to be included in a period of time from one to three months. All the specimens were stained with hematoxylin and eosin. Thirty cutaneous re-excision specimens were studied. Histopathologic examination revealed changes of epidermis, ranging from slight atrophy to moderate hyperplasia. In two cases focal ulceration was seen, with transfollicular elimination of foreign body material. The main dermal changes observed were the: 1) scar with well defined vertical orientation along the dermal suture line; 2) rounded cicatricial areas with radial branching septa of scarring tissue; 3) foreign body granuloma formation; 4) alignment of hystiocytes at the dermo-hypodermal border; 5) traumatic neuromas. The subcutaneous fat changes included: 1) lobular panniculitis with consistent presence of foam cells; 2) striking anisocytosis with pseudocystic degeneration and necrosis of adipocytes; 3) eritrocyte extravasation, mainly at the dermo-hypodermal border; 4) deep seated phlebitis. Post-surgical panniculitis is a lobular foam cell panniculitis characterized by simultaneous dermal and hypodermal changes, expression of the multi-faceted tissue response to a surgical trauma. This type of peculiar lipophagic response puts post-surgical panniculitis into the wider chapter of lipophage tissue response seen in atherosclerosis, glomerulosclerosis and some infectious models such as Mycobacterium tuberculosis and Chlamydia pneumoniae infections. Furthermore it may be seen as a reliable and convenient model for laboratory investigation on foam cell tissue response.

    ABSTRACT: Background & objectives: Kidney transplantation is the best option for patients with end-stage renal disease (ESRD) failure. Prolonged use of immunosuppressive drugs often causes opportunistic infections and malignancies of skin and mucosae, but due to lack of a careful dermatological screening in several transplantation centers the diagnosis and the treatment of dermatological lesions in kidney transplant patients are underestimated. In addition after the introduction of interleukin (IL)-2 -receptor antagonists (basiliximab/daclizumab), mTOR inhibitors and mycophenolate mofetil (MMF)/mycophenolic acid (MPA) in new immunosuppressive protocols only a few studies have analyzed the skin and mucosal lesions in kidney transplant patients. This study was undertaken to evaluate the cutaneous and mucosal diseases after kidney transplantation, and to investigate the association between these and different immunosuppressive protocols and/or demographic features. Methods: A retrospective analysis was done using medical records of kidney transplantation between 2000 and 2009 at the Transplant Unit of Fondazione IRCCS Policlinico San Matteo, Pavia, Italy. The study included 183 patients (M 57.3%, F 42.7%) aged 51.5±11.8 yr) with transplant age 52.3±34.9 months. Induction therapy was basiliximab and steroids based; maintenance therapy included combination-regimes from cyclosporine, tacrolimus, steroids, mycophenolate mofetil (MM), mycophenolic acid (MPA), rapamycin, everolimus. Anti-rejection therapy was steroid and/or thymoglobulines based. Diagnosis of cutaneous disease was made through examination of skin, mucous membranes, nails and hair evaluation. Skin biopsies, specific cultures and serological tests were done when required. Results: Skin and mucosal diseases were reported in 173 (95.7%) of patients; 88 (50.81%) showed viral lesions; 92 (53.01%) immunosuppression-related lesions; 28 (16.39%) benign tumours; 26 (15.3%) precancers /neoplastic lesions; 24 (14.21%) mycosis; 16 (9.29%) cutaneous xerosis, 15 (8.74%) dermatitis, while absence of cutaneous disease was evident only in 8 (4.37%) cases. An association between drug side effects and anti-rejection treatment ( P≤0.01) and/or calcineurin-inhibitors (CNI) exposure ( P≤0.01) was found. Longer exposure to immunosuppressive drugs (>60 months) was associated with pre-malignancy and malignancy lesions. Interpretation & conclusions: Cutaneous diseases are frequent in kidney transplanted patients. Continuous skin monitoring is necessary to make an early diagnosis and to start appropriate treatment.

    ABSTRACT: In the last years, several tyrosine kinase inhibitors (TKIs) have been developed and approved for human cancer treatment. Imatinib mesylate was the first of this novel family of drugs that target cancer-specific molecules and signalling pathways. The appearance of imatinib resistances led to the introduction of second-generation TKIs with higher potency and selectivity, such as dasatinib and nilotinib. However, the range of activity of these agents is not simply directed at tumour cells. Patients and their clinicians are indeed frequently confronted with the cutaneous side-effects associated with the employ of these drugs, which represent the most common non-hematological adverse reactions. For this reason, a systematic dermatological survey of patients receiving these therapies is highly important, and an early and appropriate dermatological treatment is required. In this review, we analyse the clinical and pathological characteristics of the most commonly reported adverse skin events associated with first- and second-generation tyrosine kinase inhibitors, with a particular emphasis on our clinical experience.

    ABSTRACT: We present a case of infantile bullous pemphigoid (BP) triggered by primary infection with varicella zoster virus and we analyze the correlation between autoantibody levels and disease activity. With this report we suggest that serum autoantibody titers may not necessarily mirror the clinical course of the disease or represent a helpful tool in guiding therapeutic decisions in infantile BP.

    ABSTRACT: Background  Dermatitis herpetiformis (DH) is a rare gluten-sensitive blistering itchy skin disease, strictly related to coeliac disease (CD). Direct immunofluorescence, demonstrating IgA granular deposits localized either in the dermal papillae or along the dermo-epidermal junction, is currently the gold standard for diagnosis of DH. It has been shown that DH immunocomplexes contain epidermal transglutaminase (eTG) and that sera from patients with DH contain antibodies specifically directed against eTG. Objectives  We studied the usefulness of serum eTG antibodies in discriminating between DH, CD and other gastrointestinal and dermatologic diseases. Methods  eTG antibodies were tested in 308 adult patients' sera: 44 patients with untreated dermatitis herpetiformis (UDH), 99 patients with untreated coeliac disease (UCD), 70 dermatological controls and 95 gastrointestinal controls. Results  In UDH eTG antibody levels were significantly higher than in DH patients on gluten-free diet, UCD, gastrointestinal controls and dermatological controls. In UCD eTG antibodies strongly correlated with tissue transglutaminase (tTG) antibodies, whereas in UDH no significant correlation was observed. Conclusion  Serum IgA eTG antibody determination can efficiently distinguish UDH from other dermatological itchy diseases and is highly sensitive to gluten-free diet.

    ABSTRACT: Imatinib mesylate (IM) is a phenylaminopyrimidine that represents the first-line treatment for chronic myeloid leukemia (CML), Philadelphia chromosome-positive. It acts as a potent and selective inhibitor of the bcr-abl fusion protein by a competitive inhibition at the adenosine triphosphate-binding site of the enzyme, which leads to the inhibition of tyrosine phosphorylation of the proteins involved in bcr-abl signal transduction. IM is generally well tolerated and usually provokes only mild side effects consisting of nausea, myalgia, edema and muscle cramps. This is a report of a patient affected by CML, who developed a photoinduced dermatitis and an oral lichenoid reaction associated with IM treatment. The lesions were resolved, thanks to the withdrawal of the therapy, and they relapsed after the reintroduction of IM, confirming the drug-induced pathogenesis. Skin changes are the most common non-hematologic side effects to IM treatment and are usually dose dependent. In particular, patients with IM therapy reported a lightening and depigmentation of the skin, that may alter the skin protection against ultraviolet exposure, with a possible subsequent intolerance to sun exposure, as reported in our patient, and higher risk of skin cancer. They are frequently self-limited or easily managed; nevertheless, in some cases, the therapy needs to be discontinued or may only be continued with concomitant oral steroid.

    ABSTRACT: Melanocytic nevi represent a widespread cutaneous finding. Nevertheless, the presence of mycosis fungoides and melanocytic nevi in the same location is an extremely rare event. We report the case of a patient affected by mycosis fungoides and treated with PUVA therapy, with complete remission of the disease. Eight years after therapy discontinuation, he presented epidermal scaling and an erythematous perinevic halo on 3 old melanocytic lesions, the clinical aspect of which was highly suggestive for Meyerson nevi. The histological and immunohistochemical examination of an excised melanocytic lesion revealed histological features consistent with the diagnosis of mycosis fungoides superimposed on junctional melanocytic nevi. The finding of patches of mycosis fungoides superimposed on melanocytic nevi is a rare event; the confounding clinical appearance with eczematous changes around a pre-existing nevus may recall the halo dermatitis known as Meyerson phenomenon; this highlights the importance of clinical and histological examination to make the correct diagnosis of dermatological diseases.

    ABSTRACT: Although no study has definitively shown that unfocused screening of skin cancer is effective, many campaigns have been organized with the aim of increasing awareness on melanoma risk factors. The objective of this study was to analyse the results of the Skin Cancer Screening Day in Italy during the period 2005-2007, to determine the priorities for melanoma control plans in a Mediterranean country. A total of 5002 patients were screened by dermatologists in 31 cities. Individuals who considered themselves to have many naevi and those with a family history of melanoma showed a higher number of common and atypical naevi. Ten melanomas, 20 basal cell carcinomas and two squamous cell carcinomas were histopathologically confirmed. Our observations provide the following suggestions for melanoma prevention strategies: (a) an unfocused campaign is suitable to inform the public about the importance of self-examination of the skin, but is not useful to identify a larger number of melanomas; and (b) melanoma screening campaigns should focus on a selected population, which meets rigorous risk criteria to maintain higher cost-effectiveness. The financial support to effective melanoma screening programmes could be increased, especially in southern populations where lower levels of self-surveillance and socioeconomic conditions represent risk factors for late identification of melanoma.

    ABSTRACT: Ecthyma gangrenosum (EG) is an unusual, potentially fatal cutaneous disease, commonly associated with Pseudomonas aeruginosa septicemia. We report the case of a 61-year-old man admitted to the Nephrology Department for fever, leukopenia and inguinal and scrotal painful lesions. Physical examination revealed inguinal and scrotal macules, nodules, blisters and ulcers with central necrosis. P. aeruginosa was isolated from an ulcer. EG was diagnosed. Because of the severe leukopenia, granulocyte-macrophage colony-stimulating factor (GM-CSF) was administered until the white blood cell count significantly increased. Based on antibiogram, intravenous ceftazidime and teicoplanin were given for 11 days. Cutaneous manifestations were completely healed in about 2 months. We suggest that the combination of GM-CSF with appropriate antibiotics can resolve EG and avoid or minimize the risk of septicemia in immunosuppressed patients.

    ABSTRACT: Background  Psoriasis is a chronic inflammatory skin disease affecting 2.0-6.5% of the European population. Although the most striking clinical features of psoriasis involve the skin, other organs including nails and joints may be affected in a substantial proportion of patients. Literature reports nail involvement in 10-56% of psoriatic patients, with common physical and social impairment. However, the precise prevalence of specific clinical features of nail psoriasis is somewhat under-reported. Objectives  Our cross-sectional study aimed at describing the prevalence and the clinical features of nail involvement in adult psoriatic patients in a psoriasis referral centre in northern Italy. Methods  A total of 178 (124 men, 54 women) consecutive adult patients (≥18 years old) with psoriasis were included. Psoriasis Area and Severity Index (PASI) and Nail Psoriasis Severity Index (NAPSI) scores were calculated for each patient. Relevant medical history was recorded. Results  Nail involvement was present in 137 (99 men, 38 women) patients (76.9%). The most common nail abnormality was onycholysis, followed by crumbling, subungual hyperkeratosis, pitting and discoloration. Pitting and onycholysis were the most prevalent patterns observed in fingernails, whereas onycholysis and crumbling were the most frequent changes detected in toenails. The most frequently and severely affected nails were the fourth fingernail and the first toenail. The average PASI score was higher in individuals with nail involvement (12.0 vs. 8.7, P = 0.06). Nail changes were present in 85.7% of patients with psoriatic arthritis. Conclusions  Our study confirms that nail involvement may be overlooked in psoriasis patients. Different psoriatic patterns in the nail affect specific digits more frequently.
