Description
Summary:Abstract Clinical presentation of paracoccidioidomycosis (PCM) can be diverse. Morphology and quantity of skin lesions depends on interactions between host immunity and fungus virulence. Diagnosis can be a challenge considering that this fungus has low virulence and some individuals have immunity to microorganism, which results in well-marked granulomas without visible microorganisms. We report herein a clinical presentation of sarcoid-like PCM, initially diagnosed as tuberculoid leprosy. This rare type of PCM is often mistaken for other types of chronic granulomatous diseases. Diagnosis was confirmed after 4 years when a special stain analysis helped in the identification of the specific etiologic agent.
