Abstract: Paraffin sections of 90 cases of basal cell carcinoma of skin were immunoltistaehomically studiod with neuro-specific enolase (NSE), calcitonin,gastrin and samatostatln for evalutation of their neuroendocrine differentiation. Multifocal positivities in cancer. nests were shown with NSE staining in nitta casts,with calcitonin in two cases,with gastrin in four cases and three with somatostatin.
