![عکس صفحه اول مقاله: Tumor formation in Hoffa's infrapatellar fat: Case report Tumor formation in Hoffa's infrapatellar fat: Case report](/preview/png/2708060.png)
Although tumors or pseudotumoral lesions are rare in the infrapatellar fat, they may affect it. Osteochondroma is the commonest benign bone tumor. However, extraskeletal presentations are rare. There are three extraskeletal variants of osteochondroma: synovial chondromatosis, para-articular chondroma and soft-tissue chondroma. We present a case of a single intra-articular lesion in the area of Hoffa's fat, in a 78-year-old female patient with a complaint of progressive knee pain associated with severe arthrosis. From the clinical and radiological findings, the diagnosis was para-articular osteochondroma. However, the histopathological findings, after excision of the lesion, showed that this was synovial chondromatosis secondary to osteoarthrosis.
ResumoTumores ou lesões pseudotumorais, apesar de raros, podem acometer a gordura infrapatelar. O osteocondroma é o tumor ósseo benigno mais comum. Entretanto, sua apresentação extraesquelética é rara. Três são as variantes do osteocondroma extraesquelético: a condromatose sinovial, o condroma para-articular e o condroma de partes moles. Apresentamos um caso de lesão intra-articular única na topografia da gordura de Hoffa em uma paciente feminina de 78 anos com queixa de dor progressiva em joelho associada a artrose grave. Pelos achados clínicos e radiológicos o diagnóstico foi de osteocondroma para-articular. Entretanto, os achados histopatológicos – após exérese da lesão – evidenciaram condromatose sinovial secundária a osteoartrose.
