title: Primary cutaneous CD30-positive anaplastic large cell lymphoma. Report of 27 cases.
abstract: The clinical, morphological and immunohistochemical features of 27 patients with anaplastic large cell lymphoma (ALCL) of CD30-positive type, with cutaneous lesions as the sole initial clinical manifestation, were analyzed. The neoplasm presented as solitary or multiple, usually ulcerated skin lesions, affecting predominantly elderly patients (median age: 67 years) with a male preponderance (male to female ratio of 6:1). In most patients, there was an excellent response to chemotherapy. The cardinal histological features included diffuse dermal and subcutaneous infiltration by large, anaplastic tumor cells, all or nearly all of which showed diffuse, strong membrane staining and frequently a paranuclear, dot-like reaction with the CD30 marker (Ber-H2). Epidermal ulceration, pseudo-epitheliomatous hyperplasia and dermal vascular proliferation were also observed.
