title: Dermatitis herpetiformis in a Japanese patient with anaplastic large cell lymphoma.
abstract: We report a 73-year-old Japanese man with dermatitis herpetiformis which developed after diagnosis of anaplastic large cell lymphoma. The patient suffered fever, sweating, shivering, and multiple enlarged cervical lymph nodes. The diagnosis of anaplastic large cell lymphoma was confirmed by the histologic features of a biopsied cervical lymph node. The patient underwent combination chemotherapy. However, one month after the initial therapy, pruritic erythematous skin lesions with peripheral vesicles appeared on his buttocks. A skin biopsy showed subepidermal blister formation associated with polymorphonuclear and mononuclear cell infiltrates. Direct immunofluorescence examination of the area adjacent to the lesion showed granular deposits of IgA at the dermoepidermal junction. While it is well-known that dermatitis herpetiformis can develop into lymphoma, there have been only a few reports of its appearance after a diagnosis of lymphoma. This case suggests that dermatitis herpetiformis may be induced by anaplastic large cell lymphoma.
