Abstract
A 70-year-old male patient who smokes and has diabetes and hypertension attended the oral medicine clinic because of a mouth sore that hurts for approximately 30 days. At physical examination, an extensive bleeding ulceration, presenting 3 centimeters in its largest diameter affecting hard palate, soft palate, and alveolar ridge on the left side, was noted. Hematologic examinations (hemogram, coagulogram, fasting blood glucose, Protrombin Time (PT), Activated Partial Thromboplastin Time (APTT), and International Normalised Ratio (INR)), biochemical examinations (Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT), Gama Glutamil Transferase (GGT), urea, and creatinine), HIV type 1 and 2, and panoramic and chest radiography were requested. There were no changes in normality in all examinations. The patient underwent incisional biopsy, and the specimen was sent for anatomopathologic examination. After analysis, the result was chronic granulomatous infection compatible with fungal infection by Histoplasma capsulatum. The patient was referred for treatment with an infectologist and currently remains without recurrence of the lesion.
