A 39 year old male presented with complaints of ongoing pain and restricted movements of right knee joint for a period of 7 years. Plain radiographs showed a calcified mass in the popliteal fossa. Open excision and biopsy was performed, and microscopic examination revealed features of extraosseous osteochondroma. Integrated clinical-pathologic diagnosis protocols are helpful in ascertaining the nature of extraskeletal cartilaginous tumours that arise at unusual anatomic sites. Complete local surgical excision is the management of choice.

“…Extra skeletal osteochondroma is rare and usually arises in the juxta-articular soft tissues without attachment to bone. Close to 40 extra skeletal osteochondromas have been reported as paraarticular, soft-tissue, capsular, intracapsular or intraarticular osteochondromas (5). Extra skeletal osteochondromas may arise in soft tissues, but the cause of their origin in soft tissues remains controversial.…”

“…This lesion is essentially extra-articular in the region of the infrapatellar fat pad ( 2 ). Sometimes, it becomes very large to stretch the quadriceps mechanism ( 3 , 4 ). Its origin is unclear, therefore the terminology used to describe these para-articular masses are confusing ( 5 - 7 ).…”

Introduction:Para-articular masses are not clear enough in terms of their etiology and nomenclature. Although surgical removal of the mass is the preferred treatment, long term follow-up after surgical treatment has not been reported yet. The current study presents a patient with the osteo-cartilaginous mass of infrapatellar region, diagnosed after a trauma. This case has the longest follow-up period in the literature.Case Presentation:A 52-year-old female patient referred after falling down on her right knee. Lateral radiographs of the knee revealed a mass in the infrapatellar area. The case was treated surgically by total excision of the mass. The mass was extra-capsular with lobular and irregular shape. After mass removal the clinical course was uneventful and at the 10-year follow-up, no signs of recurrence were evident clinically or radiologically.Conclusions:Tumor-like lesions within the infrapatellar fat pad should remind the para-articular osteochondroma. Although its etiology has not yet been elicited, operative removal of the mass is the preferred treatment of choice and also curative in long-term follow-up.

Abstract: Background: Extraskeletal cartilaginous tumors are uncommon. Osteochondromas usually arise from the metaphyseal region of the growing skeleton.
