title: [Gastric paracoccidioidomycosis. A case report and considerations on the pathogenesis of this disease].
abstract: The authors report an unusual case of fungal gastric lesion in a patient with the chronic form of paracoccidioidomycosis. For a period of 8 months the major symptoms of the patient were abdominal pain and body weight loss. The endoscopic evaluation of the upper gastrointestinal tract showed a partial gastrectomy made previously, a great and irregular ulcer in the stomach and a granulated aspect of the duodenal mucosa. A granulomatous process and Paracoccidioides brasiliensis were observed in the histopathological examination of the gastric and duodenal biopsy tissue. New endoscopic evaluation 4 months after treatment with sulfadiazine revealed healing of the gastric ulcer. It was suggested that abdominal lymph nodes involvement, duodenal infection and anatomical and atrophic alterations of the stomach were predisposing factors for the gastric paracoccidioidomycosis.
