Oral paracoccidioidomycosis in a single-center retrospective analysis from a Brazilian southeastern population.

Abstract

Paracoccidioidomycosis (PCM) is the most prevalent endemic systemic fungal infection in Latin America. In Brazil, it stands out as the eighth-highest cause of mortality among chronic or recurrent infections and has the highest mortality rate among systemic mycoses. Oral mucosal lesions may be the first visible physical manifestation of the disease. This study traced the epidemiological and clinical profiles of patients with oral lesions treated at the University Hospital Cassiano Antonio Moraes, Federal University of Espirito Santo. A retrospective cross-sectional analysis of patient medical records was performed. Among the 161 patients identified with a confirmed diagnosis of PCM, 97 (60.24%) presented with oral lesions. The male:female ratio was 15:1, the mean age was 50.5 years, and the chronic form of paracoccidioidomycosis was predominant. Most of the patients had smoking habits and were rural workers. The most common oral lesions present in various anatomical sites were mulberry-like ulcers, more frequently observed in the gingiva, with regression within one to three months. Patients completed the treatment in one to two years (32.99%), and 47.42% of cases discontinued treatment. In addition to the characteristics of the oral lesions, information from the clinical profiles of patients with oral PCM is a central tool for dentists for early diagnosis. Earlier diagnosis may result in fewer consequences, especially respiratory ones that may cause an inability to work and poor quality of life.
