RESUMO

Mycosis fungoides (MF) may present with atypical clinical manifestations. Usually it mimics various chronic dermatoses, with the appearance of ulcers during the tumour stage. Infrequently, cutaneous ulcers are the main or initial sign of lymphoma. We report the case of a man who presented multiple skin lesions that clinically appeared to be pyoderma gangrenosum (PG). However, histological and immunohistochemical examination revealed MF. This case illustrates that PG-like ulcers maybe atypical cutaneous manifestations of MF and exceptionally the presenting sign of this disease.
