“…4). It occurs distal to the patella, deep to the patellar tendon, and is intracapsular but extrasynovial [1,11,18,19,22,23]. The osteochondral densities (usually round in shape) are accompanied by loss of the normal lucency of the infrapatellar fat pad, and in over two-thirds of cases [17] there is a large pressure erosion on the inferior pole of the patella.…”

Soft tissue chondromas: diagnosis and differential diagnosis

et al. 1993

The authors evaluated three cases of soft tissue chondromas in patients aged 55, 57, and 78 years. Two of the lesions occurred in the foot and one in the hand. All three patients had long histories (over 1 year) of a palpable mass and all three had roentgenograms showing well-demarcated lobulated soft tissue lesions with both central and peripheral calcifications. Recognition of this rare benign chondroid lesion on imaging studies is significant since it may be misinterpreted as an aggressive lesion or a primary synovial abnormality.

“…Usually arising from the joint capsule or para-articular soft tissue without attachment to bone, these lesions may be large with clinical and radiological features of malignant process. These have been reported earlier as para-articular osteochondroma, intracapsular chondroma, intra-articular osteochondroma, extraosseous osteochondroma, soft tissue osteochondroma, capsular osteoma, ossification of infrapatellar fat pad, and ossifying chondroma [4–14]. …”

“…Because marginal excision is adequate management, it is important to distinguish the extraosseous osteochondroma from chondrosarcoma and synovial chondromatosis. The terminology used to describe these osteocartilaginous lesions has been historically inconsistent and confusing and so far only 21 cases have been reported in the literature [4–14] especially from the West.…”

Background. Conventional osteochondromas are common bone lesions developing in the metaphyseal region of growing skeleton. Marginal excision is the treatment of choice for such tumours. Extraosseous cartilaginous tumours are rare and their biological potential is poorly characterized. Case Presentation. A-52-year old woman presented with 3-year history of fullness and dull pain and inability to flex her left knee, sit cross-legged, or squat. Clinical and imaging studies revealed a nodular mineralised mass in the anterior portion of the knee displacing the patellar tendon laterally. Excision biopsy confirmed the diagnosis of extraosseous osteochondroma-like soft tissue mass. There is no recurrence at two-year followup. Conclusion. An integrated clinicopathological diagnosis helps to clarify the nature of extraosseous cartilaginous tumour that can arise at an unusual anatomic site. Complete surgical excision is the treatment of choice.

“…Several cases have been reported [4,5,[8][9][10][11] since the first two described by Jaffe in 1958 [7], but, still, only 23 intra-articular or paraarticular chondromas have been well documented [3,5]. In their review of 18 cases collected from the literature and their own four new cases, Steiner et al [3] found that 20 of these intracapsular and paraarticular chondromas were located on the knee.…”

Intracapsular chondroma is a rare lesion that has been reported under different names on 23 occasions. We describe a 52-year-old woman with intracapsular chondroma that involved the left knee. Radiologically, the mass was multilobulated, calcified, and sharply circumscribed and was lying between the patella and the anterolateral surface of the tibia. The peculiar histologic pattern of the tumor was composed of hyaline cartilage nodules with enchondral ossification or calcification, in apparent transition with septa of connective and adipose tissue. The most common differential diagnoses for this tumor are primary synovial chondromatosis and chondrosarcoma. We emphasize a possible metaplastic origin of the chondromatous component due to some mechanical posttraumatic disturbance of the infrapatellar fat pad. To our knowledge, the present case is the second intracapsular chondroma to be described in the European literature. Int J Surg Pathol 5(1/2): [49][50][51][52][53][54] 1997
