Resumen

Sporotrichosis is a subacute-to-chronic infection endemic to tropical and subtropical regions. It usually involves subcutaneous tissue but can occasionally cause extracutaneous infections, especially in hyperendemic areas. Extracutaneous infections are classified based on the anatomic location of the lesion and the route of infection (primary or multifocal). The clinical forms are as follows: (i) pulmonary (primary or multifocal); (ii) osteoarticular (primary or multifocal); (iii) ocular (ocular adnexal lesions including eyelid lesions, conjunctivitis and dacryocystitis, and intraocular infections); (iv) central nervous system; and (v) mucosal (primary or disseminated). Multifocal clinical presentations are observed mainly in immunocompromised individuals. The diagnosis must be confirmed in the laboratory by mycological examination of the clinical samples. Itraconazole and amphotericin B are the most commonly used antifungal agents for treating pulmonary, osteoarticular, ocular, and mucosal forms. Treatment may include surgical excision of the initial lesions in pulmonary and osteoarticular forms. The treatment of neurological involvement is far from optimal and is associated with a high mortality rate despite long treatment periods. Copyright
