Frozen tissue sections of biopsies from head and neck squamous cancer lesions were examined for immunohistochemical staining with a recently developed monoclonal antibody, designated as SQM1 antibody and directed against the surface membrane of squamous carcinoma cells. SQM1 antibody stained selectively squamous carcinoma, while normal mucosa and cells of the stroma were non-reactive. Positive staining of tumor was found in 33/35 specimens obtained from several major sites of the head and neck area and was observed in primary manifestations and lymph node metastases as well as in recurrences. The most consistent reactivity was seen with carcinomas of the tongue. Well differentiated squamous carcinomas contained a higher proportion of SQM1 positive tumor cells than poorly differentiated carcinomas. We suggest that the SQM1 antibody may aid in the immunohistochemical identification of squamous carcinoma of the head and neck area.
