P160 Paracoccidioidomycosis severe: Bizarre presentation in the face

POSTER SESSION 2, SEPTEMBER 22, 2022, 12:30 PM - 1:30 PM: INTRODUCTION: Paracoccidioidomycosis is a systemic mycosis caused by the dimorphic fungus Paracoccidioides brasiliensis. The disease is restricted to Latin America. It is the principal systemic mycosis in Brazil, with higher incidences in the southern, southeastern and central regions. OBJECTIVES: It's to report a case of paracoccioidomycosis with a bizarre presentation on the face. CASE REPORT: A 54-year-old male farmer from Açailândia, Maranhão, with a history of an extensive ulcerated lesion that started in the right wing of the nose. After 6 months of evolution, the lesion had already spread reaching the nasal and oral mucosa, evolving with acute respiratory failure, requiring tracheostomy (Fig.1). He was referred to the Cancer Hospital for a biopsy, which was referred for pathological examination, showing an intense inflammatory infiltrate consisting of lymphocytes, histiocytes, neutrophilis with giant, multinucleated cells that phagocytize refrigerant bodies, compatible with paracoccidioidomycosis. Material sent for direct examination and culture, showed positive for Paracoccidioides sp. After PCR amplification of the genetic material and sequencing, P. brasiliensis was identified. Chest tomography showed sparse ground-glass attenuation, but affecting both lungs and radiodense striations in the lower lobes bilaterally. Treatment was established with liposomal amphotericin B, with a good therapeutic response (Fig. 2). The patient was discharged from the hospital using itraconazole and still upper outpatient follow-up, with good healing of the lesions. CONCLUSION: Paracoccidioidomycosis can get a severe presentation, distancing the physician from the diagnosis, showing that in all these situations, simple tests, such as the direct examination of lesional material or sputum can elucidate the diagnosis. We need to think about it in endemic area.
