Pachydermodactyly is a rare form of digital fibromatosis mostly affecting young men. It is characterized by asymptomatic, protracted, bulbous soft tissue swellings on proximal phalangeal and proximal interphalangeal joint areas of fingers. Histopathologic findings represent hyperkeratosis, acanthosis, and thickening of the dermis due to increased collagen bundles. There is also mucin deposition in the dermis. Intralesional infection of steriods is helpful in relieving the skin lesions. We report a case of pacgydermodactyly manifested as soft tissue swellings unilaterally on the lateral aspects of fingers. The lesions showed a good response to triamcinolone intralesional infections. (Kor J Dermatol 1996;34(3) : 459 ~ 462)
