Abstract

Intracapsular and paraarticular chondroma is a rare benign lesion of the large joints (mostly the knee). We report a case of intracapsular and paraarticular chondroma in the infrapatellar Hoffa's fat pad that presented as a painful palpable mass in 15-yearold woman. A physical examination revealed a firm, movable and tender mass in the infrapatellar area. Magnetic resonance images showed an ovoid, well-defined, soft tissue mass with focal calcification in the infrapatellar fat pad. The final pathology revealed an intracapsular and paraarticular chondroma.
