Non-mycosis Peripheral T-Cell non-Hodgkin Lymphoma involving the Skin.

A 64 years old male presented with reddish lesions all over the body of 1 month duration, high grade fever with evening rise of temperature and chills. No lymphadenopathy or hepatosplenomegaly were noted. Multiple infiltrated erythematous and hyperpigmented patches and plaques were present on the face, trunk and extremities along with few oral erosions. Histopathology from skin showed features of mycosis fungoides (MF). A further workup with Immunohistochemistry was suggestive of peri pheral T-cell lymphoma, not otherwise specified diag nosis (PTCLNOS). We report a case of PTCLNOS in a man mimicking MF clinically and histopathologically.
