Oral involvement in mucormycosis. A retrospective study of 55 cases.

INTRODUCTION: Mucormycosis with oral involvement (OIM) is a rare opportunistic and lethal mycosis, which has increased in the last decade and is generally associated with uncontrolled diabetes and neutropenia. METHODS: A retrospective study of cases with OIM was carried out in a tertiary-care center. Mycological and histological examinations were performed, and the isolated organisms were identified by morphology and molecular biology. RESULTS: Fifty-five OIM patients were included, with a median age of 38 years (61.8% males). The most frequent associated disease was type-2 diabetes mellitus (61%), followed by neutropenia due to acute lymphocytic leukemia (27%). The main presentation was palatal and mandibular ulcers (92.7%) and, to a lesser extent, gingival and lingual necrosis. The diagnosis was established by mycological and histopathological studies. The most frequent fungi isolated was Rhizopus arrhizus (67.2%). CONCLUSION: OIM is a rapidly progressing disease, therefore, an early diagnosis and the proper control of predisposing factors is necessary, and consequently, contributing to improve the outcome of mucormycosis.

Introducción: La mucormicosis con afectación oral (MAO) es una micosis oportunista, letal y poco frecuente, pero que ha aumentado en la última década y que generalmente se asocia a diabetes descontrolada y neutropenia. Métodos: Se realizó un estudio retrospectivo de casos con MAO en un centro de tercer nivel. Se realizaron examen micológico e histológico, y los organismos aislados se identificaron por morfología y biología molecular. Resultados: Se incluyeron 55 pacientes con MAO, con una mediana de edad de 38 años (61,8% varones). La enfermedad asociada más frecuente fue la diabetes mellitus tipo 2 (61%), seguida de la neutropenia por leucemia linfocítica aguda (27%). La presentación principal fueron úlceras palatinas y mandibulares (92,7%) y, en menor medida, necrosis gingival y lingual. El diagnóstico se estableció con estudios micológicos e histopatológicos. El hongo más frecuentemente aislado fue Rhizopus arrhizus (67,2%). Conclusión: La MAO es una enfermedad de rápida evolución, por lo que es necesario un diagnóstico precoz y un adecuado control de los factores predisponentes y, en consecuencia, contribuir a mejorar la evolución de la mucormicosis.(AU)
