  La histoplasmosis es una micosis profunda que produce enfermedad pulmonar al inhalarse aire con contenido de microconidias del hongo Histoplasma capsulatum, presentandose con mayor incidencia en pacientes inmunocomprometidos; la infeccion bucal generalmente es secundaria a la pulmonar clasificandose como variante sistemica. Se presenta un caso de paciente femenina de 60 anos de edad, inmunocompetente, asintomatica, que es referida por presentar gingivitis persistente al tratamiento periodontal. Al examen clinico se observo lesiones eritematosas de aspecto granulomatoso en encia superior vestibular lateral izquierda y encia palatina extendiendose a mucosa palatina, las cuales en su inicio pasaron inadvertidas al simular una gingivitis por irritantes locales. Con signos de focos de calcificacion diseminado en la radiografia de torax se procedio a la realizacion de biopsia incisional, evidenciandose caracteristicas microscopicas consonas con histoplasmosis bucal, es referida al Servicio de Neumonologia e Infectologia indicandose como tratamiento Itraconazol por via oral, erradicandose la infeccion en su totalidad.

  Histoplasmosis is a deep mycosis that causes lung disease by inhaling air containing microconidia of the fungus histo-plasma capsulatum, presenting with a higher incidence in immunocompromised patients; the oral infection is generally secondary to the pulmonary infection, being classified as a systemic variant. We present a case of a 60-year-old female patient, immunocompetent, who is referred for presenting persistent gingivitis to periodontal treatment. On clinical examination, erythematous lesions with a granulomatous appearance were observed in the upper left lateral vestibular gingiva and palatal gingiva extending to the palatal mucosa, which initially went unnoticed by simulating gingivitis due to local irritants. With signs of a disseminated calcification foci in the chest X-ray, an incisional biopsy was performed, evidencing microscopic characteristics consistent with oral histoplasmosis. She was referred to the Pneumonology and Infectious Diseases Service, indicating oral Itraconazole as treatment, eradicating the infection in its entirety.
