A Case of Primary Cutaneous Diffuse Large B-cell Lymphoma / 대한피부과학회지

ABSTRACT

Primary cutaneous diffuse large B-cell lymphomas are characterized by a non-epidermotropic monotonous infiltrate of large follicular center cells with various proportions of centroblasts, large centrocytes, multilobated cells or immunoblasts without extracutaneous manifestations. We report a case of a 61-year-old man, who presented with several, annular plaques on the trunk. The clinicopathologic features and immunohistochemical profiles were diagnostic of primary cutaneous diffuse large B-cell lymphoma.
