title: Non-lymphoid lesions that may mimic cutaneous hematopoietic neoplasms histologically.
abstract: This review considers neoplastic lesions that originate in the skin, and which have the potential to imitate hematopoietic proliferations at a histological level. They include lymphoepithelioma-like carcinoma, Merkel cell carcinoma, benign lymphadenoma, pseudolymphomatous angiosarcoma, lymphadenoid dermatofibroma, lymphomatoid atypical fibroxanthoma, histiocytoid (epithelioid) hemangioma, and inflamed melanocytic lesions. The clinical and pathological features of those tumors are considered.
