    ABSTRACT: Monoclonal gammopathy may manifest itself through a range of skin disorders, including plane normolipemic xanthoma and necrobiotic xanthogranuloma. The present paper describes two patients with these cutaneous symptoms. The first has extensive areas of skin affected by flat xanthomas, monoclonal gammopathy with > 10% infiltration of bone marrow with clonal plasmocytes and, according to PET-CT, unclear lymphadenopathy in the retroperitoneal area. The size of this lymphadenopathy (histologically no malignant infiltration and no confirmed infectious aetiology) has not changed significantly over a 4-year follow-up. Repeated PET-CT scans showed decrease in SUV value in this infiltration from 7.5 to 3.8. Four cycles of treatment with a combination of bortezomib, cyclophosphamide and dexamethasone brought neither reduction in monoclonal immunoglobulin nor change to skin morphology. We believe that the abdominal lymphadenopathy is associated with xanthomatosis but have been unable to confirm this unequivocally. The second patient is being followed up for more than 10 years, originally for MGUS, later for asymptomatic multiple myeloma. Last year, painful subcutaneous and cutaneous infiltrates, isolated on an upper limb and more frequent on lower limb, started to occur. These infiltrates are palpable. PET-CT imaging provided an excellent depiction of these infiltrates, showing no pathology on the head, chest and abdomen and no osteolytic foci on the skeleton. CT imaging showed clearly numerous infiltrates in the skin and subcutaneous tissue of lower limbs, particularly both shanks, reaching up to 2 cm in depth. The largest infiltrate, measuring 3.5 by 2 by 10 cm, was identified in the distal dorsal part of the right shank. PET imaging of lower limbs showed distinctly pathological accumulation in all infiltrates described above; the accumulation of glucose in the lower part of the right shank reached 10.0 SUV. CT images of lower limbs showed increased density saturated hypodermis even in the areas where there is no increased accumulation of 18 fluoroglucose. Following 40 Gy irradiation, the size of infiltrate in the radiated area decreased and their soreness ceased. Conclusion: PET-CT imaging offered information on extra-cutaneous signs of plane normolipemic xanthomas and provided excellent depiction of the areas of the skin and hypodermis affected by necrobiotic xanthogranuloma. Chemotherapy with cyclophosphamide, bortezomib and dexamethasone brought no reduction in monoclonal immunoglobulin concentration, and no reduction in plane normolipemic xanthomas. Radiotherapy targeted at large foci of xanthogranulomas led to partial regression and ceased infiltrate soreness.

    ABSTRACT: Our paper describes 5 patients with a vascular malformation - angiomatosis. In the first patient, a young man, angiomatosis affected the stomach, intestine, the area of mesenterium and retroperitoneum as well as mediastinum. Angiomatous mass had invaded pelvic bones and vertebrae. Treatment was initiated with interferon alpha in a maximum tolerated dose of 3 million units 3 times a week. Because of low efficacy of interferon alpha, thalidomide was added at a dose of 100 mg per day. Bone pain disappeared following a few applications of zoledronate administered in regular monthly intervals. After 3 years of concomitant administration of interferon alpha and thalidomide, we changed the regimen due to adverse effects and are administering thalidomide and interferon alternatively in 4-monthly intervals. Treatment has resulted in 50% reduction, according to imaging, of angiomatous mass, reduced intensity of disseminated intravascular coagulation and disappearance of clinical signs. The second was a case of multiple angiomatosis affecting the intestine only (multiple intestinal angiodysplasias) where we used thalidomide monotherapy. This treatment reduced blood losses and haemoglobin concentrations rose to normal levels. This male patient had consumed 120 transfusion units per year before the initiation of thalidomide. The third case was a slowly progressing vascular malformation of the face. This vascular malformation troubled its sufferer by spontaneous shortening that could not be resolved surgically because of its fragility. Two years of combined treatment with interferon a 6 million unites 3 times a week and thalidomide 100 mg daily led to a reduction and flattening of the malformation, paling of its colour and ceasing of spontaneous bleeding. This development enabled minor surgery--partial excision of this large vascular malformation. Histology examination confirmed that there was no evidence of new capillary formation. Histological examination thus confirmed efficacy of the treatment. The fourth case involved a patient with large vascular malformations affecting supraclavicular region of the neck and nape in whom radiotherapy was applied (54 Gy) leading to a reduction of the malformation mass by a at least 50%. The fifth is a case of an extensive periorbital lymphangioma that diminished following treatment with interferon alpha. These cases illustrate the benefits of combined treatment including thalidomide and interferon alpha in patients with multiple angiomatosis or large proliferating hemangioma (vascular malformation). If combined treatment with thalidomide and interferon a is not possible, it is beneficial to use thalidomide monotherapy. Radiotherapy is another alternative, although it is necessary to apply doses exceeding 50 Gy which may not be always possible.

    ABSTRACT: Monoclonal gammopathy-associated IgA pemphigus is a debilitating skin disorder with inconsistent response to treatment. A 61-year-old woman with IgA pemphigus and monoclonal gammopathy of unknown significance had been treated unsuccessfully with cyclophosphamide/dexamethasone and then with rituximab. When the monoclonal gammopathy progressed to multiple myeloma, the patient received treatment with cyclophosphamide/doxorubicin/dexamethasone but there was no clinical response. Second-line therapy with a thalidomide/cyclophosphamide/dexamethasone combination led to severe exacerbation of the skin disorder. However, therapy with a combination regimen that included bortezomib, cyclophosphamide and dexamethasone resulted in complete and durable remission of multiple myeloma and IgA pemphigus. This suggests that bortezomib-based therapy is useful for the treatment of the rare dermatologic disorder associated with IgA gammopathy.

    ABSTRACT: IgA pemphigus, resembling subcorneal pustulous dermatosis, represents a rare complication of IgA type monoclonal gammopathy. The patient dates the onset of initial symptoms of vesicular-bullous disease to 1990. She was first examined at our clinic in 2001 with the following conclusion "type IgA monoclonal gammopathy of unknown significance". The first immunosuppressive treatment of vesicular-bullous disorder was administered in 2003 (dexamethasone 20 mg on days 1-4 and 15-18 in monthly cycles + daily cyclophosphamide 50 mg). Cyclophosphamide was administered for 6 months in total and dexamethasone for further 3 months. During the treatment, intensity of the skin disorder ameliorated and monoclonal IgA levels decreased to non-detectable levels. Nevertheless, skin symptoms recurred immediately after dexamethasone treatment in its original intensity was terminated, even though the concentration of monoclonal immunoglobulin IgA remained below the sensitivity of quantitative detection for further 6 months (positive immunofixation only). Six rituximab 600 mg infusions were administered in a weekly interval after stopping cyclophosphamide and dexamethasone to prevent early recurrence of skin symptoms but this treatment was without any lasting effect. Transformation into multiple myeloma was identified in 2007. First line treatment (cyclophosphamide, adriamycin and dexamethasone - CAD) remained without any haematological or dermatological treatment response. Second line treatment (thalidomide, cyclophosphamide and dexamethasone - CTD) brought about significant deterioration of skin symptoms up to the clinical picture of erythrodermia. Third line treatment (bortezomib 1.3 mg/sqm i.v. on days 1,4, 8 and 15, cyclophosphamide 50 mg daily and dexamethasone 20 mg on days 1-4 and 15-18 in 28-day cycles - VCD) resulted in rapid decline in monoclonal immunoglobulin IgA concentrations immediately following the first cycle and to negative immunofixation after 5 cycles. In total, six VCD cycles were administered. The patient has had no skin symptoms from the third cycle of this treatment and complete skin and haematological remission has been maintained for 12 months after completion of bortezomib-containing treatment. Combined treatment containing bortezomib has proven useful in the treatment of IgA pemphigus accompanying monoclonal gammopathy of uncertain significance transformed into multiple myeloma.

    ABSTRACT: Anti-basement membrane zone (anti-BMZ) antibodies are detectable in a low percentage of elderly subjects without clinical signs of bullous pemphigoid (BP). BP may initially mimic other pruritic dermatoses and may be more common in patients with diabetes mellitus (DM), since DM is frequently associated with pruritic disorders. The aim of the present study was to analyse a possible association of BP and DM and to detect subclinical BP among elderly patients with pruritic dermatoses. Ninety elderly patients (78.6 +/- 4.7 years) treated for dermatologic conditions were divided into four groups: I. DM+/pruritus+, II. DM-/pruritus+, III. DM+/pruritus-, and IV. DM-/pruritus-. Patients' sera were tested by indirect immunofluorescence (IIF) on monkey oesophagus; positive or dubious results were further evaluated by ELISA with human recombinant BP180 and BP230 proteins and purified laminin 5. Positive results were found in 1 of 21 (4.8%) patients in group I, 6/31 (19.3%) patients in group II, 1/18 (5.5%) patients in group III, 3/20 (15%) patients in group IV. In the whole cohort positive anti-BMZ antibodies of linear or basal cell cytoplasmic and membrane pattern were found in 11 cases (12.2%). ELISA was positive in 11/29 (37.9%) tested sera for at least one antigen (BP180, BP230 and laminin 5 ELISA was positive in 7, 5, and 2 sera, respectively). Positive IIF corresponded with positive ELISA in 6/11 (54.5%) cases (ELISA with BP180, BP230, laminin 5 was positive in 5, 3, and 1 serum, respectively). Thus, by IIF, a significant portion of elderly patients had anti-BMZ antibodies and these findings were confirmed by ELISA. There was no statistically significant difference in the presence of anti-BMZ antibodies among the groups I-IV. Thus, the association of anti-BMZ antibodies with age overrules the potential association with DM and/or pruritus.

    ABSTRACT: Juxtaglomerular cell tumor (JGCT) is an uncommon tumor of the kidney, typically found in young adults. Patients with this tumor suffer from hypertension, hyperaldosteronism and hypokalaemia. Expression of renin and intracytoplasmatic rhomboid crystals or granules in electron microscopic picture are diagnostic features of this tumor. CD34 and CD117 immunoreactivity have recently been reported as helpful markers of JGCT.

    ABSTRACT: Cutaneous lymphomas represent a unique group of lymphomas and are the second most frequent extranodal lymphomas. As with other neoplasias, the pathogenesis is based mainly on a stepwise accumulation of mutations of suppressor genes and oncogenes caused by genetic, environmental or infectious factors. The diagnostic work-up includes clinical, histological, imaging and hematological investigations and in many cases immunohistochemical and molecular biological analyses. The current WHO/EORTC classification of cutaneous lymphomas differentiates "mature T-cell and NK-cell lymphomas", "mature B-cell lymphomas" and "immature hematopoietic malignancies", their variants and subgroups. It is compatible with the WHO classification for neoplasias of the hematopoietic and lymphoid tissue and respects the organ-specific peculiarities of primary cutaneous lymphomas.The assignment of the various types of cutaneous lymphomas into prognostic categories (pre-lymphomatous "abortive" disorders; definite malignant lymphomas of low-grade malignancy; definite malignant lymphomas of high-grade malignancy) provides essential information on the biological behavior and allows an appropriate planning of the therapeutic strategy, which may be topical or systemic and aggressive or non-aggressive. Besides the classical options for therapy, there are new and "experimental" strategies, the efficacy of which has to be studied in clinical trials.

    ABSTRACT: The new WHO/EORTC classification for cutaneous lymphomas comprises mature T-cell and natural killer (NK)-cell neoplasms, mature B-cell neoplasms, and immature hematopoietic malignancies. It reflects the unique features of lymphoproliferative diseases of the skin, and at the same time it is as compatible as possible with the concepts underlying the WHO classification for nodal lymphomas and the EORTC classification of cutaneous lymphomas. This article reviews the histological, phenotypical, and molecular genetic features of the various nosological entities included in this new classification. These findings always have to be interpreted in the context of the clinical features and biologic behavior. To review the histological, phenotypical and molecular genetic features of the various nosological entities of the new WHO/EORTC classification for cutaneous lymphomas. Extensive review of the literature cited in Medline and own data of the authors. The WHO/EORTC classification of cutaneous lymphomas comprises mature T-cell and NK-cell neoplasms, mature B-cell neoplasms and immature hematopoietic malignancies. It reflects the unique features of primary cutaneous lymphoproliferative diseases. This classification is as much as possible compatible with the concept of the WHO classification for nodal lymphomas and the EORTC classification of cutaneous lymphomas. The histological, phenotypical and molecular genetic features always have to be interpreted in the context of the clinical features and biologic behavior.

    ABSTRACT: Marking excision margins of surgical specimens by silver impregnation has several advantages over commonly used Indian ink: during the slicing the tissue preserves its natural color, the staining is permanent, and the pigment does not smudge over cutting surfaces. The pigment is clearly visible in tissue sections. The tissue specimen is shortly dipped into a 10% water solution of argent nitrate (AgNO3 with HNO3). After slicing, the tissue specimens are developed in common black & white developer for several seconds and paraffin processed as usual. The method is suitable for formaldehyde fixed as well as fresh tissue specimens.

    ABSTRACT: Image resolution required for reference histological images is high. Obtaining high-resolution images requires a system, composing large image from individual smaller components. Such systems must thus be capable of automatically taking individual image parts, performing shading compensation and fusion of the image parts into one large image. Distribution of such images over the Internet requires developing a suitable user's interface with access to the image details. The ways of creating high-resolution images (virtual slides) and the interface enabling access to image details using Internet browser are described. A collection of about 3200 dermatopathological, mostly histologic images is available at http://www.muni.cz/atlases: Hypertext atlas of dermatopathology. Methods of high-resolution image acquisition were used in digitizing the collection of skin lymphomas (Dermatology Institute, University Hospital, Zurich), which is a part of the atlas. The atlas is continuously maintained and upgraded; the number of contributors is growing.

    ABSTRACT: Composing microscopic images of very high resolution from several parts posed some problems. One of them was the necessity to adjust the focusing level when moving from one part to another. Re-focusing lead to problems with joining the image parts, which did not correspond exactly, and the area of image fusion was noticeable. A computer program was developed to overcome these problems. Our program worked with all the image parts together to find their optimal order for image fusion. Individual image parts were joined using a steep gradient running along a randomly generated curve. This method gave good results even in images with background or holes in the tissue. The method of composing large images from individual parts was used for digitizing the skin lymphoma collection of the Institute of Dermatology, University Hospital, Zürich. This collection of digital images is a part of the 6th version of Hypertext atlas of Dermatopathology at www.muni.cz/atlases.

    ABSTRACT: Oncocytic cardiomyopathy is a rare arrhythmogenic disorder usually associated with female sex, difficult-to-control arrhythmias, or sudden death of infants and children. Morphologically, it is characterized by the presence of oncocytic cells, which are diffusely distributed or form the nodular structures within the myocardium, occasionally involving the valves, with a large number of mitochondria in cytoplasms. We present two cases of oncocytic cardiomyopathy. The first case had a fatal clinical outcome, and the other case was surgically treated. The nuclear expression of skeletal muscle transcription factor MyoD1 was demonstrated in the first case, supporting the theory that oncocytic cardiomyopathy is a conduction system developmental disorder. To confirm this hypothesis, it is necessary to further investigate myogenic transcription factor program in human cardiac conduction system cells.
