title: beta-2-Microglobulin in primordial and differentiated basocellular carcinomas and basosquamous carcinomas.
abstract: 27 cases of basocellular carcinomas and basosquamous carcinomas of the skin were classified into primordial and differentiated basocellular carcinomas and basosquamous carcinomas and stained for beta-2-microglobulin using the immunoperoxidase technique. All the differentiated basocellular carcinomas and some of the basosquamous carcinomas contained beta-2-microglobulin, but none was found in the primordial basocellular carcinomas. Staining of basal cell tumors for beta-2-microglobulin may be helpful in interpreting adnexoid and epidermoid differentiation in skin tumors.
