[Systematic study of gastrectomy specimens for cancer, in search of synchronous carcinomas].

Multiple carcinomas were searched in 50 successive gastrectomies, 17 females (34%) 33 males (66%) from 40 to 83 years old. Macroscopic handling of the specimens included pinning on a board, fresh, half-fixed and completely fixed examination, not only by naked eye but also through a magnifying glass. The stomach were totally studied, according to Japanese method.

[Basocellular epithelioma. Considerations on its histogenesis].

Twenty-nine cases of basal cell carcinoma were studied with immunoperoxidase techniques for the detection of carcinoembryonic antigen. Results presented in the text would indicate that a high percentage of basal cell carcinomas have sweat gland histogenetic origins and that this is independent of its morphologic features. The use of immunohistochemical techniques in the detection of biological markers demonstrates once again their value not only in identifying a disease but also in determining its histogenetic origins.
