RESUMO

This study describes the histopathological findings in the tongues of 92 patients with advanced AIDS autopsied and 15 patients who died of other reasons. The autopsy was perfonned in the Service of Verification of Death of the Capital of School of Medicine of the University of São Paulo between 1997 to 2001. Tongues were dissected and divided in 4 regions (anterior, medial, posterior and lateral) and six fragments for each region were stained with Hematoxylin &Eosin, periodic acid-Schiff, Grocott, Brown-Hopps, Zielh-Neelsen and Mucicannim. The contral group (n= 15), it presented six cases of mild non-specific chronic glossitis and one intramuscular lypoma that was not clinically diagnosed. We observed in the AIDS advanced group, 42 cases of hairy leukoplakia, 31 of candidosis, 29 of non-specific chronic glossitis, 17 of non-specific chronic ulceration, 13 of melanotic pigmentation, 10 of herpes simplex, 2 of cryptococcosis, 2 of lymphoepithelial cysts, 1 of histoplasmosis, 1 of mycobacteriosis, 1 of cytomegalovirosis and 1 case of non-Hodgkin lymphoma. Simultaneous lesions occurred in the tongues of 18 patients, being hairy leukoplakia with melanotic pigmentation the most common associated lesion. Gram+ bacteria affected the lingual surface more than Gram bacteria. In 57 cases (87,6%) the leveI of CD4 T lymphocytes in peripheral blood of aidetic group was below of 50 cells//lL. The frequency of each region of tongue affected by the lesions was lateral (42,22%), anterior (25,33%), medial (17,33%) and posterior (15,11 %). Cryptococcosis, histoplasmosis, mycobacteriosis and cytomegalovirosis did not occur only in the tongue, but also in other organs. Infectious, cysts, and neoplastics lesions that were not clinically diagnosed we observed microscopically on the tongue of aidetic group. Immunohistochemistry, "in situ" hybridization and polymerase chain reaction studies for bacterial, fungal and viral detection could be helpful to understand the tongue involvement in AIDS
