“…PSO is an uncommon benign disorder in which hyaline cartilage nodules form in the synovial tissue of the joint, tendon sheath or bursa. These nodules are usually detaching from the synovium and can occupy the entire joint [1][2][3]. Our patient was a young male, with a long history disease and progressive aggravation of joint mobility.…”

“…Our patient was a young male, with a long history disease and progressive aggravation of joint mobility. Previous studies showed that synovial chondromatosis can be highly aggressive and destructive, so a late diagnosis could severely affect the prognosis of the patient [2][3][4][5]. Microscopic appearance of PSO is composed of lobules of hyaline cartilage, surrounded by synovial lining (a two-cell layer of cuboidal epithelium).…”

“…Patients usually are in the 4 th or 5 th decades of life and men to female ratio is 2:1 to 4:1. The knee is affected preferentially (up to 70%); however, the disorder can arise in any other joint [1][2][3][4][5][6].…”

Multimodal ultrasonographic evaluation in a case with unossified primary synovial osteochondromatosis

et al. 2018

Primary synovial osteochondromatosis is a rare disorder and its diagnosis remains a challenge to the physician. We present the case of 36 year old patient with right knee monoarthritis in which ultrasound findings, corroborated with clinical and histopathological evidence confirmed the diagnosis of unossified primary synovial osteochondromatosis. The arthroscopy with synovectomy found multiple intra-articular loose bodies occupying the entire joint. The ultrasonographic findings were extensively evaluated.

Extra‑articular synovial osteochondroma of the Hoffa's fat pad involving the patellar tendon: A case report and literature review

et al. 2020

Synovial osteochondroma (SO) is a relatively uncommon tumor affecting the synovial joints that is characterized by the development of hyaline cartilage from the synovial membrane. The basic pathophysiology of SO is thought to be the metaplastic change of the synovium to hyaline cartilage. Large extra-or para-articular lesions in the Hoffa's fat pad are relatively uncommon. A 56-year-old woman complained of knee pain associated with a large lesion on the anterior of the right knee. She also had restricted range of motion in the knee. Examination revealed an elastic hard 8x9-cm lesion involving the patellar tendon. Computed tomography and magnetic resonance imaging demonstrated a mosaic-intensity mass lesion in the inferior side of the Hoffa's fat pad as well as the patellar tendon. The patient underwent needle biopsy. Histological analysis revealed a solitary SO. There were no atypical features suggestive of malignancy and the mass was resected marginally. The patient had no recurrence or knee functional disorder 3 years postoperatively. There are no reports of SO involving the patellar tendon with restriction of range of motion. Removal of the mass lesion for management for SO, as in the present case, is unusual. To the best of our knowledge, this is the first case of extra-articular SO in the Hoffa's fat pad involving the patellar tendon causing a restriction of range of motion of the knee. Marginal surgical resection improved knee function.

A rare case of giant synovial osteochondromatosis of the thigh

et al. 2019

Rationale: Giant synovial osteochondromatosis of the thigh is a highly unusual disease without standard diagnosis and curative managements so far. Our focus is to report a very rare case of giant synovial osteochondromatosis successfully operated by surgical treatment. The management of these unique cases has certain educational significance in clinical practice. Patient concerns: A 63-year-old previously healthy man presented to our institution with a 4-year history of continuous progressive hip pain and local numbness of right side in January 2018. One month ago, the patient felt that the above symptoms were aggravated, and the right hip and proximal thigh were significantly swollen. Diagnosis: Computed tomography and magnetic resonance imaging of the hip revealed the irregular mass in his right thigh. Post-operative pathology confirmed the diagnosis of synovial osteochondromatosis of the thigh. Interventions: Considering the large volume of the mass and possibility of malignancy, the patient underwent surgical exploration and complete tumor resection. Outcomes: The patient's neurological deficits and symptoms improved significantly after the surgery, and the postoperative period was uneventful at the 1-year follow-up visit. There were no complications associated with the operation during the follow-up period. Lessons: Taken together, the lesion's clinical features, imaging results, and pathological characteristics are unique. Synovial osteochondromatosis of the thigh, although rare, should be part of the differential diagnosis when the patient presents with local pain, numbness, swelling or other symptoms. We recommend surgical treatment for the occupying lesion when the tumor has caused symptoms or neurological deficits.
