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.

“…10 Histologicamente apresenta trabeculado ósseo característico da ossificação endocondral coberto por uma camada de cartilagem hialina. 1,8 Concluímos, portanto, que, no caso apresentado, os achados radiográficos de lesão única e localizada na topografia da gordura de Hoffa favorecem o diagnóstico de osteocondroma para-articular secundário a doença de Hoffa. Entretanto, histologicamente a lesão é compatível com condromatose sinovial.…”

Hoffa’s Osteochondroma - Para-articular Extrasynovial Infrapatellar Fat Pad Osteochondroma: A Case Report

et al. 2021

View full text Add to dashboard Cite

Osteochondroma usually arises from the metaphyseal region of growing bones. The occurrence of extraskeletal osteochondroma is rare with very few case reports. Para-articular osteochondroma is a type of extraskeletal osteochondroma. It frequently occurs around the knee, usually at infrapatellar Hoffa’s fat pad. It is usually intracapsular but extrasynovial and arises from the capsule and connective tissues due to osteocartilaginous metaplasia. We present a case of 19-years male with anterior knee pain for 3 years, swelling, and deformity of the knee with flexion limitation for one year. Radiography revealed ovoid, corticated lesion free from adjoining bones. Mass interpreted as benign, so planned for excision. Well circumscribed nodule excised from the medial parapatellar approach. Histology revealed cartilaginous tissues surrounded by fibrous tissues with scattered enchondral ossification.Postoperatively and subsequent follow-up resulted in pain-free joint, complete recovery of range of motion with no clinicoradiological evidence of recurrence.
