Sarcoidosis associated with mycosis fungoides

In November 1966, a 47-year-old black woman had a skin eruption and an abnormal chest roentgenogram that were found to be due to sarcoidosis. In September 1974, nodular lesions and subsequently generalized exfoliative dermatitis developed that were found to be due to mycosis fungoides. The concurrence of sarcoidosis and mycosis fungoides has been recorded only once in the literature. The depression of cell-mediated immunity found in this patient and other sarcoid patients suggests that impairment of the host's immunosurveillance system may predispose to the development of T-cell lymphomas.
