    Abstract:
    BACKGROUND: Paracoccidioidomycosis is a systemic fungal infection common in Latin America. Cutaneous involvement is frequent and usually affects multiple sites, being most frequently associated with lesions of the oropharyngeal mucosa. The cutaneous form on its own is rare. PATIENTS AND METHODS: We report a case of paracoccidioidomycosis isolated from the ear of a 43-year-old immunocompetent man. The lesion consisted of a partially ulcerated plaque on the auricle of the left ear. Direct examination, histopathological examination and PCR revealed the presence in the skin lesion of yeasts identified as Paracoccidioides brasiliensis. DISCUSSION: The sites of paracoccidioidomycosis on the ear can be confused with other tropical diseases frequently found in the Amazon region such as leishmaniasis, leprosy and lobomycosis. The absence of any other cutaneous sites in this case raised the question of whether the lesion was of primary or secondary origin.
