Tumor and specific infection should be considered in addition to osteoarthritis. We report a case of intracapsular and paraarticular chondroma in the infrapatellar Hoffa's fat pad that presented as a painless limited knee in 64-year old man. A physical examination revealed a firm, movable mass in the infrapatellar area. Radiographs and Magnetic resonance images showed an ovoid, well-defined, soft tissue mass with focal calcification in the infrapatellar fat pad. The mass was completely resected surgically through a medial parapatellar approach. The final pathology revealed an intracapsular and paraarticular chondroma. At follow-up, 3 years after the operation, patient was pain-free, with complete recovery of the range of motion of the knee and without any clinical or radiographic evidence of recurrence. Intracapsular and paraarticular chondroma is a rare benign lesion of the large joints (mostly the knee). The Pathogenesis of these tumours is controversial. The diagnosis is made with correlation of clinical, radiological and histological features. The treatment of choice is surgical excision.

Acta Scientific Orthopaedics, Dec 1, 2022

Osteochondroma is a benign bone tumor developing especially in long bone metaphysis in children. ... more Osteochondroma is a benign bone tumor developing especially in long bone metaphysis in children. It can be involved in hereditary multiple exostoses disease (HME) or an isolated tumor. It rarely develops in spine and pelvis. We report a rare localization of a voluminous osteocnondroma developing from iliac crest in a five-year-old child initially followed for HME. In clinical exam this mass was hard, immobile but not adherent to the overlying skin. No hip joint stiffness was observed. X ray showed a pedenculated tumor with high-density and clear boundarie developing from ilium lateral fossa. This exam revealed also smaller asymptomatic exostoses in distal femur and proximal tibia. CT scan showed a "cauliflower like" tumor. The child complains from pain while lying in a right side and when wearing trousers. En-bloc excision was performed by direct approach. Histological study confirms diagnosis showing a cartilage cap and abundant cellular hyaline cartilage and chondrocytes. There was no recurrence at two years follow up and the child is regularly seen in outpatient department for the other osteochondroma locations.

It is a bone non-microbial inflammatory disease that frequently involves long bones, pelvis and spine. The autoimmune origin seems to be the most suggested pathogenic theory. It often manifests by multifocal bone pain with insidious onset and recurrent course Objectives The aim of the study was to highlight specific symptoms, frequent localization, investigations, imaging and multidisciplinary management of CRMO Methods We retrospectively reviewed five children on follow up for CRMO in our institution on both pediatric orthopedic and rheumatology department between 2012 and 2022. We have noted epidemiology features, symptoms, clinical manifestations, medical and orthopedic management, sequallae and outcome at last follow up for each case in order to identify specificities and correlations Results Five children, including 3 female and 2...
