Paracoccidioidomycosis is a systemic fungal infection endemic to Central and South America. It is associated with a broad spectrum of clinical manifestations and has been classified into acute and chronic forms. The latter is the most common type and usually affects male agricultural workers in rural communities. The disease typically begins in the lungs producing varying degrees of parenchymal damage, and in a significant number of cases the organism spreads through bronchogenic, lymphatic, or hematogenous routes to involve 1 or more organs. Bone and joint infection is relatively uncommon and has not been well described in the English literature. Much of the information on this form of the disease has been derived from radiographic and autopsy studies on patients with severe or fatal infections in whom skeletal involvement was a minor or incidental finding. We describe our experience with 9 cases in which osteoarticular manifestations were the sole or 1 of the few major complications of the disease. All 9 patients were male, from 9 to 49 years of age (mean, 36.6 yr). Six were farmers. Evidence of visceral infection was present in 6 patients, in all of whom the lungs were considered the primary site of disease. The osteoarticular lesions were symptomatic in all cases, with the duration of symptoms ranging from 1 week to 2 years. The lesions were centered in bone in 2 cases: they manifested radiographically as circumscribed areas of lysis with or without a rim of sclerosis. The disease was centered in joints in 7 cases; the associated radiographic changes included evidence of joint effusion, periarticular bony erosions, and narrowing of the joint space. Biopsy of the involved skeletal site revealed compact or loose granulomas containing variable numbers of fungi. Although follow-up information was not available for all patients, those treated with TMP-SMX (and 1 patient who also received amphotericin B) and who were followed had prompt resolution of their signs and symptoms. Our findings substantiate some of what is known about the epidemiology of bone and joint involvement in chronic paracoccidioidomycosis. Our patients exhibited features of skeletal infection that have not been emphasized previously, however, including 1) frequent involvement of large joints or long bones of the extremities, 2) presentation with relatively rapidly developing musculoskeletal symptoms, and 3) manifestation as a solitary joint or bone lesion with or without concurrent clinically detectable pulmonary disease. Bone and joint paracoccidioidomycosis should be considered in the differential diagnosis in patients who have skeletal lesions with or without pulmonary involvement and have either lived in or traveled through endemic areas. Early diagnosis and treatment with antifungal medications can achieve an excellent outcome with limited local sequelae.
