title: A case of stasis papillomatosis associated with psoriasis vulgaris.
abstract: A markedly obese, 41-year-old Japanese man who had suffered from psoriasis vulgaris for several years visited us with elephantiasis-like swelling of his lower legs of three months' duration. His right lower leg showed marked papillomatosis with thick scales, and the left lower leg was eroded and papillomatous. Although direct lymphography of his lower extremities showed no abnormality, indirect lymphography revealed local lymphatic damage in the involved skin. Histological examination showed hyperkeratosis, marked papillomatosis, proliferation of capillaries in the upper dermis, and lymphectasia in the lower dermis. The lesions were much improved by washing and topical use of corticosteroids for two months. It was suspected that obesity and the preceding psoriatic lesions caused local lymphatic disturbances, followed by the development of stasis papillomatosis.
