Overview
Paracoccidioidomycosis (also known as Lutz-Splendore-Almeida disease or Brazilian blastomycosis) is a mycosis caused by the fungus Paracoccidioides brasiliensis. Sometimes called South American blastomycosis, paracoccidioidomycosis is caused by a different fungus than that which causes blastomycosis.
Historical Perspective
Lutz-Splendore-de Almeida disease is named for the physicians Adolfo Lutz, Alfonso Splendore, and Floriano Paulo de Almeida, who first characterized the disease in Brazil in the early 20th century. [1]
Classification
Paracoccidioidomycosis may be classified according to Franco et al. in 1987 into: paracoccidioidomycosis infection, paracoccidioidomycosis disease, paracoccidioidomycosis associated with inmunosupression and residual form (sequela). Based on the duration of symptoms, paracoccidioidomycosis disease may be classified into: acute, subacute or chronic. The chronic form can be subclassified into: unifocal and multifocal.[2][3]
Pathophysiology
Spores of Paracoccidioides spp. are transmitted via the respiratory route to the human host. Following transmission, Paracoccidiodes spp. particles invade the terminal bronchioles and alveoli where granulomas are formed, but can be inactive for approximately 40 years. [3] On microscopic histopathological analysis, a pilot's wheel or Mickey mouse ears-like appearance are a characteristic finding of PMC. [4] [5] [6]
Causes
Differential Diagnosis
Paracoccidioidomycosis must be differentiated from tuberculosis, histoplasmosis and metastasis. [7]
Epidemiology and Demographics
Paracoccidioidomycosis has been reported as an autochthonous disease, that tends to affect agriculture workers from southern Mexico to northern Argentina. Paracoccidioidomycosis is prevalent in Brazil, Colombia, Venezuela, and Argentina, and is classically associated with individuals from rural areas. The typical patient is a man aged 30 to 50 years. [8] PMC disease affects men, more commonly than women. However, PMC infection can affect anyone. [3]
Risk Factors
Common risk factors in the development of paracoccidioidomycosis disease are: age, gender, poor hygiene, occupation, malnutrition, tabacco and alcohol consumption. [2] [9]
