Paracoccidioidomycosis manifesting as oral lesions: clinical, cytological and serological investigation.
Paracoccidioidomycosis (South American blastomycosis) is a systemic mycosis which can be associated with oral lesions. This study on a group of 14 patients showed oral lesions mainly on the gingival or alveolar mucosa, with pulmonary involvement detectable on chest radiography in most. Microscopic detection of the fungus on a direct smear showed positive results in all 14 patients. Serological investigations including immunodiffusion, counterimmunoelectrophoresis and immunoblot were also positive in 100% of cases. The results suggest that direct smear together with serology may obviate the need for lesional biopsy for the diagnosis of oral paracoccidioidomycosis.
