Cutaneous T-cell Lymphoma of the Mycosis Fungoides Variant: A Case Report

Primary cutaneous lymphomas comprise a diverse group of T- and B-cell-related diseases. Their heterogeneity has made diagnosis and classification challenging. Of all the existing subtypes, mycosis fungoides is the most common. We present the case of a 62-year-old Mexican man who had been treated for chronic dermatitis and subsequently underwent a skin biopsy. The biopsy revealed mycosis fungoides, and he is currently being treated with corticosteroids while awaiting re-evaluation to determine if he requires phototherapy. Mycosis fungoides presents a diagnostic and therapeutic challenge among cutaneous lymphomas, characterized by an insidious onset and a multifactorial etiopathogenesis.
