A Case of Bednar Tumor / 대한피부과학회지

Bednar tumor is an uncommon pigmented subtype of dermatofibrosarcoma protuberans(DFSP). The histopathological finding is characterized by a typical storiform pattern composed of spindle-shaped cells resembling DFSP except for the presence of melanin-containing cells scattered within the lesion. The origin of the spindle-shaped cells and melanin-containing cells within the tumor remains unknown. We report a case of Bednar tumor in a 26-year-old woman on the right shoulder which was presented as asymptomatic, firm, black-colored, 1x1.5 cm nodule over 2 years. Histologically, the proliferated spindle-shaped cells showed a cartwheel pattern and stained positively with CD34, similar to those of a common DFSP. The tumor was widely excised and there is no evidence of recurrence from follow-up of 6 months.

A Case of Kaposi's Sarcoma Occurring in Membranous Glomerulonephritis / 대한피부과학회지

Kaposi's sarcoma is a neoplasm of multifocal origin which manifests primarily as vascular nodules in the skin and other organs. Kaposi's sarcoma in iatrogenically immunocompromised patients is the result of immunosuppressive therapy in organ-transplant recipients, autoimmune disease patients and cytotoxic chemotherapy in cancer patients. We report a case of Kaposi's sarcoma in a 50-year-old man who developed well-defined purple-colored papules and plaques on both hands and feet after prednisolone treatment for underlying membranous glomerulonephritis. The histologic finding showed abnormally proliferated and dilated vessels, vascular slits, spindle-shaped cells and extravasated erythrocytes in the dermis. He was treated with cryotherapy, and the dosage of prednisolone was reduced. Improvement was seen in 6 weeks

Pigmented Contact Dermatitis Due to After Shave Lotion / 대한피부과학회지

Pigmented contact dermatitis is characterized by a dark brown pigmentation that results from repeated exposure to small amounts of contact allergen. Histopathologic findings are liquefactive degeneration of the basal layer cells and melanophages in the upper dermis. We report a case of a 73-year-old man with dark brownish mottled hyperpigmented patches on the both cheeks and forehead. Patch tests were positive to isoeugenol, benzyl salicylate and after shave lotion. After shave lotion that the patient used maybe contain these fragrances. Improvement was seen 3 months after ceasing the use of after shave lotion.

Two Cases of Generalized Granuloma Annulare Treated with PUVA / 대한피부과학회지

Granuloma annulare is a benign granulomatous disease which has an unknown etiology and it is represented by typical annular lesions. Recently various therapeutic modalities have been suggested such as intralesional injections of steroid, chloroquine, dapsone, surgical excision and so on. But any satisfactory result has not been reported yet. In the first case, a 65 year-old-man, Polycyclic, erythematous patches with raised edges were noted on the upper arm spreading to the trunk and both lower extremities for the past 3 years. In the second case, a 63-year-old man, numerous match-head sized skin-colored papules were detected on the sun exposed area such as both shoulders, upper extremities and hands dorsum for the past 3 months. On the histological examination of back, hands dorsum respectively, incomplete degeneration of collagen bundles surrounded by lymphocytes, histiocytes in a palisade pattern and a few giant cells were found in the dermis. Two patients were treated with systemic PUVA, one for 2 months and the other, 4 months.

A Case of Nodular Pseudosarcomatous Fasciitis / 대한피부과학회지

Nodular pseudosarcomatous fasciitis is characterized as rapidly growing benign tumor with microscopically resembling sarcoma in the upper extremities, especially forearms. Most lesions are located in the subcutaneous tissue, although these may also be found intramuscularly, with the involvement of the adjacent fascia or periosteum and dermis.

A Case of Churg-Strauss Syndrome With Acute Glomerulonephritis / 대한피부과학회지

Churg-Strauss syndrome is a rare systemic vasculitis diagnosed by the presence of any four or more of six criteria which include asthma, eosinophilia>10%, mono- or poly-neuropathy, nonfixed pulmonary infiltrate, paranasal sinus abnormality, extravascular eosinophils. In a 65 year-old-woman, multiple purpura and crusted ulcer with central necrosis were developed on the both extremities and buttocks 1 month ago. She has been suffered from asthma, sinusitis and recurrent pneumonia since ten years ago Laboratory findings showed hematuria, hypereosinophilia and hyperIgE. On the histological examination of ulcerative nodule on the right leg, leukocytoclastic vasculitis and many neutrophils and eosinophils around the cutaneous vessels were seen and the other findings were fibrinoid necrosis and thickening of vessels wall without eosinophilic granulomatous changes. Renal biopsy showed focal segmental glomerulonephritis and sclerosing nephritis. We report a rare case of Churg-Strauss syndrome with acute glomerulonephritis.

A Case of Drug Eruption Caused by Itraconazole / 대한피부과학회지

Drug eruptions are common, occurring in 2% to 3% of hospitalized patients. The majority of reactions are mild, accompanied by pruritus, resolving promptly after the offending drug is discontinued. An eruption caused by itraconazole is very rare and there have been no previous reports in Korea. A 60-year-old man was seen with multiple erythematous papules and patches that appeared after oral administration of itraconazole and gradually the skin lesions changed to purpura. Given the widespread use of itraconazole for onychomycosis, a purpuric drug eruption should be considered a rare complication of therapy.

Emollient Phototherapy of Pityriasis Lichenoides Chronica / 대한피부과학회지

Pityriasis lichenoides Chronica is a cutaneous disorder of unknown etiology and characterized pathologically by vasculitis and clinically by its marked chronicity and lack of specific treatment. Emollient-phototherapy is a recently introduced effective treatment for psoriasis. The authors treated 3 patients with pityriasis lichenoides chronica by the emollient-phototherapy technic with quite satisfactory results.
