Mycosis fungoides (MF) is a neoplastic proliferation characterized by cutaneous infiltration of atypical T-lymphocytes. MF often shows diagnostic difficulties. Histopathology, immunochemistry, and clonality determination may be an auxiliary diagnostic method but they are not always sufficient and the final diagnosis should be made with correlation of clinical findings, routine histopathology, immunohistochemistry, and gene rearrangement studies. Histopathological findings may also vary in different stages of the disease. In this article, the histopathological findings of classical MF and its variants are reviewed together with their immunohistochemical features.
