A Japanese case of ulcerative colitis associated with dermatitis herpetiformis and primary sclerosing cholangitis.

: A number of extraintestinal complications of ulcerative colitis have been described. However, only a few cases of ulcerative colitis associated with dermatitis herpetiformis have been documented. We report a case of ulcerative colitis associated with dermatitis herpetiformis and primary sclerosing cholangitis in a Japanese woman.

Giant xanthomatous dermatofibroma--a case distinguished histologically and immunohistochemically from invasive fibrohistiocytic tumors.

A 50-year-old woman presented with a skin tumor on her right calf. The tumor had been noticed 20 years previously and grew to more than 60 mm in diameter. The histological findings were characterized by numerous bland xanthomatous histiocytes and a few atypical giant cells with pyknotic nuclei, although mitotic figures were few.

[Adult dermatomyositis with angiopathy and cecum perforation].

This previously healthy 43-year-old man was admitted to our hospital with a history of rash, dysphagia and severe myalgia for two months. Physical examination showed prominent edema and erythema over the face and the chest, scattered ulcerations on the trunk, and muscle atrophy most prominent proximally. Serum levels of muscle enzymes were remarkably increased.

Localized cutaneous cryptococcosis successfully treated with itraconazole. Review of medication in 18 cases reported in Japan.

A case of localized cutaneous cryptococcosis successfully treated with oral itraconazole is reported. The patient, a 63-year-old Japanese housewife, had had an erythematous and partly eroded lesion in the area of her right earlobe for about 10 months. No findings suggesting a primary focus of Cryptococcus infection were found in the lung, central nervous system or other internal organs.

[Pilomatrix carcinoma--report of the second case in Japan and a review of the literature].

A 53-year-old man had a rapidly growing tumor, measured 3 cm in diameter, on his left temporal region of 2 months' duration. The lesion showed histological resemblance to pilomatricoma but differed by the presence of irregular nests of atypical basophilic cells (basaloid cells) with focal squamoid differentiation and a large number of atypical mitoses. A review of 16 cases of pilomatrix carcinoma documented since the year of 1980 indicated that this tumor occurs in males three times more frequently than in females.
