[Immunohistochemistry in the anatomopathologic diagnosis].
In order to determine the value of immunohistochemical staining methods for morphologic diagnosis specimens of 949 cases received at the Immunohistochemistry Laboratory of the Department of Pathology of the Medical School of Botucatu, in the period 1984-1989 were reviewed. All of them were submitted to the immunoperoxidase staining (PAP or ABC). The main morphologic diagnosis was confirmed in 468 cases (49.3%); the definitive diagnosis was made in 244 cases (25.7%) that had only differential diagnosis, and contributory information was provided in 74 cases (7.8%); the immunohistochemical staining was non-contributory in 114 cases (12%). It rendered an unsuspected diagnosis in 49 cases (5.2%). The analysis of these cases shows that immunohistochemical methods may provide important and sometimes essential informations for definitive diagnosis. This technique is particularly useful for distinguishing between carcinoma, lymphoma and melanoma.
