Sclerodactyly in a patient with mycosis fungoides.
A 44-year-old man had mycosis fungoides and generalized plaque disease involving 80% of his skin surface with diffuse lymphadenopathy and alopecia of the scalp and groin. In addition, distal to the wrist, there were sclerodermatous changes involving the skin of the hands with associated sclerodactyly of all digits with loss of normal palmar creases. There were no subungual telangiectasis or digital ulcers. The changes in the hand that occurred in this case, no doubt arose as a result of the patient's neoplasm. Abnormalities of collagen biosynthesis and degradation probably occur with mycosis fungoides as a result of the extensive infiltration of the epidermis and dermis with malignant cells. To our knowledge, the association of sclerodactyly with mycosis fungoides has not been previously reported.
