[Osteoarticular coccidioidomicosis. Clinical and pathological study of 36 Mexican patients]. / Coccidioidomicosis osteoarticular: estudio clinicopatológico de una serie de 36 pacientes mexicanos.

UNLABELLED: Coccidioidomycosis (CM) is primarily a lung disease. Systemic spread occurs in 1% of cases and one of its manifestation is osteoarthritis. AIM: To describe the clinical and pathological characteristics of 36 patients with osteoarthritis by Coccidioides immitis (COA). MATERIAL AND METHODS: The surgical pathology records of two medical institutions were reviewed; patients with clinical diagnosis of osteoarthritis and definitive histopathological diagnosis of COA were included in the study. Results were analyzed by contingence tables (RXC) and chi2 test. RESULTS: Twenty six adults (19 men, seven women) and 10 children (seven males, three females) were studied. The chi2 analysis demonstrated a predominance of disease in men (72.2%, p = 0.008). There was no difference between males and females in relation to history of mycotic disease or diagnosis of lung disease after the diagnosis of COA. Bone involvement (76% of cases) was more frequent that pure joint lesions and the predominant radiological lesion was of lytic type. 30.5% of patients (11 cases) had multiple bone lesions and eight of them were men with multiple vertebral bone lesions. DISCUSSION: The COA was the only manifestation of disease in 83% of the patients. Therefore is important to consider this etiology in patients of endemic area. The clinical and radiological spectrum of COA is wide and may include a dentigerous and synovial cyst or simulates metastatic disease. The recognition of the clinical manifestations of COA may contribute to an opportune diagnosis and treatment.

La coccidioidomicosis (CM) es una enfermedad primariamente pulmonar. La diseminación sistémica ocurre en 1% de los casos y una de sus manifestaciones es la osteoartritis. Objetivo. Conocer las características clínicas y patológicas de 36 pacientes con osteoartritis por Coccidioides immitis (OAC). Material y métodos. Se revisaron los archivos de patología quirúrgica de dos instituciones y se incluyeron aquellos pacientes que consultaron por enfermedad osteoarticular y cuyo diagnóstico final histopatológico fue de CM. Los resultados se analizaron con tablas de contingencia (programa RXC) y prueba de . Resultados. Se estudiaron 26 adultos (19 hombres, siete mujeres) y 10 niños (siete hombres y tres mujeres). La prueba de mostró un predominio de casos en hombres (72.2%, p = 0.008). No hubo diferencia entre hombres y mujeres en relación con antecedentes de enfermedad micótica ni en el diagnóstico de enfermedad pulmonar posterior al diagnóstico de OAM. El compromiso óseo (76% de los casos) fue más frecuente que las lesiones articulares puras y la imagen radiológica predominante fue la osteolítica. De los casos estudiados, 30.5% (11 casos) presentaban lesiones óseas múltiples. De estos 11 casos, ocho eran hombres que en su mayoría presentaban lesiones vertebrales dorsales bajas y lumbares. Discusión. En 83% de los pacientes que se presentaron por OAC, esta fue la única manifestación de la enfermedad. El espectro clínico y radiológico de OAC es muy amplio y puede presentarse como un quiste dentígero, un quiste sinovial o simular enfermedad metastásica. El reconocimiento de esta variedad de presentaciones clínicas en individuos de zonas endémicas puede contribuir a un diagnóstico oportuno y tratamiento específico.
