Primary cutaneous anaplastic large cell lymphoma is a rare cutaneous T-cell non-Hodgkin’s lymphoma without systemic involvement. It usually presents as reddish brown ulcerated nodules or indurated plaques. The diagnostic criteria include clinical and pathologic features including the presence of at least 75% of the tumor cells expressing CD30. A 66-year-old male presented with tender zosteriform confluent reddish soft nodules and dark brownish papules on the right thigh which persisted for eight years. Histological examination demonstrated diffuse infiltration of medium and large anaplastic lymphoid cells with abundant cytoplasm in the dermis. Immunohistochemical evaluation showed positive staining for CD3 and CD30. Based on the clinical features and the corresponding immunohistochemical findings of the tumor, it was diagnosed with primary cutaneous anaplastic large cell lymphoma. Herein, we emphasize the need for suspicion of cutaneous malignancy in the presence of long-standing zosteriform lesion.
