Lacaziosis mimicking borderline tuberculoid leprosy

Lacaziosis is a chronic skin infectious disease caused by the fungus Lacazia loboi, which usually results in indolent cutaneous keloid-like lesions. It was first described by jorge Loho, in 1931, in a patient from the Amazon region. We report a case of lacaziosis, manifested by an erythematous infiltrated plaque, causing misdiagnosis with paucibacillary leprosy, since both diseases are endemic in Amazon basin.
