This article describes a rare case of PCDLBCL-LT and discusses its clinical, dermoscopic, and pathological features, as well as the therapeutic response.
Primary cutaneous diffuse large B-cell lymphoma-leg type (PCDLBCL-LT) is characterized by diffuse monotonous proliferation of centroblasts and immunoblasts. It commonly presents as erythematous to violaceous nodules on one or both the legs and has a poor prognosis. We report the clinico-dermoscopic-pathological features and therapeutic response of a rare case of PCDLBCL-LT in a 62-year-old diabetic man, who presented with multifocal plaques, one lobulated and two arcuate-shaped, on the face and scalp. During the investigation, one of the plaques had eroded the underlying bone without any evidence of malignant cells in the cerebrospinal fluid. He was successfully treated with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) along with intrathecal methotrexate.
