title: Single oral paracoccidioidomycosis mimicking other lesions: report of eight cases.
abstract: Paracoccidioidomycosis is a fungal infection caused by Paracoccidioides brasiliensis. It is an endemic disease, representing a serious health problem in Latin American countries. This infection primarily affects the lungs and is acquired by inhalation of the fungus. It can spread to other organs and tissues, mainly the oral cavity affecting more adult men from 30 to 50 years of age. On clinical presentation, several signs associated with impaired general and nutritional conditions can be noted. Oral manifestation is more common in the soft palate, gingiva, lower lip, buccal mucosa, and tongue. The classical clinical presentation is a superficial ulcer with granular appearance and hemorrhagic points. Usually, the oral lesion is extensive and generalized. Although uncommon, when the oral manifestation is single, others lesions, particularly squamous cell carcinoma, must be included in the differential diagnosis. In this article, the authors discuss the unusual presentation of eight cases of single oral paracoccidioidomycosis and its diagnostic importance.
