    ABSTRACT: Vulval involvement is an uncommon extraintestinal manifestation of Crohn's disease, and it is very rare in children. Patients with vulval CD typically present with erythema and edema of the labia majora, which can progresses to extensive ulcer formation. Vulval CD can appear before or after intestinal problems or it may occur simultaneously.

    ABSTRACT: A 22-year-old female presented to the dermatology department with a 8-month history of blistering lesions over the left forearm and face. Most of the bullae and erosions were perfectly round and of nearly the same size. In absence of any obvious etiological, precipitating or aggravating factor, a provisional diagnosis of dermatitis artefacta (self-inflicted dermatological lesions) was made. A detailed anamnesis revealed that stress caused by her ex-boyfriend's threats and apprehension of consequences prompted her to create the lesions using a hot spoon. The patients of dermatitis artefacta usually present to dermatologists as their pathology manifests as unexplained and variable cutaneous lesions which may go undiagnosed for a long time. It is important for the dermatologist to have a high index of suspicion to recognise the underlying psychopathology.

    ABSTRACT: Primary mucosal melanoma of the oral cavity is an exceedingly rare neoplasm which is estimated to comprise 1-2% of all oral malignancies. In contrast to cutaneous melanomas, the risk factors and pathogenesis are poorly understood. The predominate localization of primary oral melanoma is hard palate and maxillary alveolus. Dermoscopy may be utilized as an adjunctive tool in the clinical differential diagnosis of oral mucosal melanoma whenever the lesion is accessible with a dermoscope. Surgery is the mainstay of treatment, but it may be challenging depending on the location of the tumor within the oral cavity and its size. Adjuvant therapy with dacarbazine, platinum analogs, nitrosoureas and interleukin-2 have been utilized with low response rates. Imatinib may be effective for patients with with c-Kit gene mutations. Sunitinib and dasatinib have been reported effective in selected cases. Vemurafenib and dabrafenib are targeted agents for patients with BRAF mutation-positive melanoma. Ipilimumab, an anti-cytotoxic T-lymphocyte antigen 4 antibody and pembrolizumab, a monoclonal antibody targeting programmed death 1 receptor may be a feasible treatment option in patients with metastatic mucosal melanoma.

    ABSTRACT: Several combinations of different skin tumors occuring one adjacent to the other or even in a single lesion have been described up to date. Collision tumors involving atypical fibroxanthoma and melanoma are extremely uncommon. Herein we present a case of melanoma associated with AFX and discuss on the usefulness of dermoscopy in the clinical diagnosis of collision tumors.

    ABSTRACT: Hepatitis C viral infection is a significant public health problem; 170 million persons are infected worldwide and the prevalence in the southern part of the United States exceeds two percent. Extrahepatic manifestations of hepatitis C viral infection are common; notably, 15-20% of patients will develop cutaneous manifestations of their disease. There are numerous dermatologic diseases associated with hepatitis C infection, including lichen planus, leukocytoclasticvasculitis, and porphyria cutaneatarda.

    ABSTRACT: Pustular psoriasis of the digits (acrodermatitis continua of Hallopeau) may be localized to one or more digits for over an extended period of time. Characteristic presentation is that of tender, diffusely eroded, and fissured pustular plaques on one or more digits. Transition to other forms of psoriasis and to generalized pustular psoriasis is known to occur. These patients have an increased risk of acute generalized exanthematous pustulosis (AGEP) compared to the general population. Pustular psoriasis is often therapy resistant.

    ABSTRACT: Over the past few years melanoma has grown into a disease of socio-economic importance due to the increasing incidence and persistently high mortality rates. Melanoma is a malignant tumor with a high tendency to metastasize. Therefore, an extremely important part of the therapeutic process is to identify the disease at an early stage: in situ or stage I. Many tools for early diagnosis of melanoma are available today, including dermoscopy, videodermoscopy and in vivo reflectance confocal microscopy. Other methods such as high frequency ultrasound, optical coherence tomography and electrical impedance spectroscopy may serve as additional diagnostic aids. Modern imaging techniques also allow the monitoring of melanocytic skin lesions over months or years to detect the moment of malignant transformation. This review summarizes the current knowledge about modern diagnostic techniques, which may aid early diagnosis of melanoma.

    ABSTRACT: Oleoma is defined as a foreign body granuloma resulting from the injection of oily substances into the skin or subcutaneous tissue. Liquid injectable silicone has been used extensively over the last five decades for soft tissue augmentation. Although initially considered as a biologically inert material, it has been implicated in a variety of adverse reactions, sometimes with latent periods of decades. We describe the case of a 44-year-old Peruvian woman presenting with multiple painless yellowish papules and plaques limited to the lower half of the breasts, that seemed to be cutaneous xanthomas. A skin biopsy showed granulomatous inflammation with multiple clear vacuoles corresponding to injected liquid silicone particles, diagnosed as oleoma. The patient was then re-evaluated and she reported that she underwent breast augmentation by injection of liquid silicone five prior to presentation in our department. Thus, the diagnosis of oleoma was confirmed. We describe a case with yellowish papules on both breasts in a woman that underwent breast augmentation by injection of liquid silicone. Since this unusual presentation of oleomas can be confused with cutaneous xanthomas, a biopsy is essential for diagnosis.

    ABSTRACT: Pancreatic panniculitis is a rare complication of pancreatic disease occurring in 2% to 3% of all patients, most commonly those with acute or chronic pancreatitis. We report the case of a pancreatic panniculitis associated with acute pancreatitis in a 63-year-old man. He presented with a 2-day history of multiple tender subcutaneous nodules, followed by nausea, vomiting, severe epigastric pain and loss of appetite, hours before admission. Laboratory and radiologic findings revealed acute pancreatitis. Histopathological examination from a skin biopsy specimen taken from a nodule showed a mostly lobular panniculitis with "ghost cells", without vasculitis. Nodules disappeared with the resolution of acute pancreatic inflammation, as amylase and lipase levels returned to normal. Panniculitis may be the first manifestation of pancreatic disease. Therefore clinicians must have a high index of suspicion for the diagnosis of pancreatic panniculitis.

    ABSTRACT: Although the underlying primary cause of chronic wounds may vary, a common etiology of this is a hypoxic or ischemic status of the affected tissue of the lower extremities. In particular, for rare diseases associated with disturbed blood flow a correlation between cause and effect is often diagnosed inappropriately. As a consequence, chronic wounds may develop and persist for years. We present a case of a patient with chronic venous insufficiency due to an occlusion of the inferior caval vein. Initially, a Budd-Chiari syndrome was diagnosed which is a thrombotic obstruction of the hepatic venous outflow. In addition, the patient developed an obstruction of the inferior caval vein and subsequently a chronic venous insufficiency. As a consequence, chronic leg ulcers developed with a history of more than 7 years. Various wound care approaches were performed without success in wound closure. Finally, a combination of compression therapy and topical application of a hemoglobin solution successfully led to fast and persistent wound closure. Chronic ulcers of the lower limb such as venous leg ulcers, even for patients with rare disorders like Budd-Chiari syndrome, are associated with oxygen supply disturbances resulting in a hypoxic status of the affected tissue. Therefore, an adequate oxygen supply to chronic wounds plays a pivotal role in successful wound healing. Compression therapy in combination with enhancement of the local oxygen supply by topically applied hemoglobin showed marked improvement of wound healing in the presented patient.

    ABSTRACT: Bullous pemphigoid is a cutaneous autoimmune blistering disorder. The etiology for what precipitates this disease is not entirely clear at this point, although it has been associated with certain medications. We describe the case of a 70-year-old male with a past medical history of diabetes type 2 who developed a diffuse eruption of bullae with skin biopsy positive for bullous pemphigoid. He had previously been prescribed sitagliptin 50 mg daily for at least one year prior to onset of his disease. The medication was discontinued and the patient was treated with first IV and then oral steroids with good clinical outcome. There have been a few reports that have explored the relationship between DPP-IV inhibitors (gliptins) and bullous pemphigoid, including three case series and a report on sitagliptin associated allergic skin reactions submitted to the Adverse Event Reports System database of the FDA. According to the Naranjo ADR probability score there is a "possible" cause and effect relationship for this case. The enzyme DPP-IV is ubiquitously expressed in almost every organ system, including the skin. The exact mechanism at this time is unknown but is believed to be multifactorial involving many aspects of the immune system. Our case and the findings from our literature review further demonstrate a link between dipeptidyl peptidase-IV inhibitors and the development of bullous pemphigoid.

    ABSTRACT: Mucous membrane pemphigoid (MMP) is a subepithelial autoimmune mucocutaneous disease. It most frequently affects the oral mucosa, followed by ocular and nasal mucosa, nasopharyngeal, anogenital, skin, laryngeal and esophageal mucosa. Two half-sisters developed mucous membrane pemphigoid at approximately the same age. The older sister presented with primarily mucosal disease, while the younger had a more cutaneous disease. The histopathology demonstrated a subepithelial blister and direct immunofluorescence showed deposition of IgG and C3 at the basement membrane zone of perilesional tissues in both sisters. Antibodies to human β4 integrin were present in the sera of both patients and correlated with disease activity. Both sisters carried the same HLADQβ1* 0301 allele. This is the first case of mucous membrane pemphigoid occurring in two half-sisters. Perhaps, it is the low incidence of mucous membrane pemphigoid that may account for the lack of reports on familial cases of the disease.
