Eruptive dermatofibromas and immunosuppression

Multiple and eruptive dermatofibromas are, on the contrary, unusual. Often the patients who show this peculiar cutaneous pattern are referred for immunosuppressive therapy or they have an immunosuppressive disease. We report the case of a woman affected by mycosis fungoides, who developed, in 2 months, 14 dermatofibromas on her legs. The personal history of the patient revealed a previous immunosuppressive treatment with systemic corticosteroids for interstitial pneumonia. Different etiological hypothesis have been proposed to explain the eruptive presence of multiple dermatofibromas and the alteration of the immune response, but the real mechanism is still unclear. Dermatofibromas are benign tumours usually encountered in dermatology
