HISTOPLASMOSIS IN A MAN WITH AIDS: CASE REPORT

Abstract

Histoplasmosis is a systemic infectious disease caused by Histoplasma capsulatum. Patient, male, 40 years old, melanoderma, with AIDS, referred from a Reference Center for Tropical Diseases for stomatological care, complaining of a "tongue lesion". Nothing noteworthy was seen in the extra-oral examination. Intra-oral, a nodular lesion disseminated in a red tongue, papillary and ulcerated surface with sessile base. The clinical diagnosis was Histoplasmosis and Paracoccidioidomycosis. An incisional biopsy was performed and the histopathological sections were stained with hematoxylin and eosin (HE) revealing a granulomatous inflammatory process associated with pseudoepitheliomatous hyperplasia compatible with histoplasmosis. Positive PAS reaction and Grocott staining; and negative in the Ziehl-Neelsen staining. The patient died before starting the treatment. This case reinforces the importance of the stomatologist and oral pathologist in the elucidation of cases of systemic diseases when it is shown exclusively in the mouth and the diagnostic challenge.
