Lakhsmi KS, Niranjan Gowda MR, Jayanthi KJ, Veni U


Background: Osteochondromas (OC) are common benign bone tumours presenting as bony protuberances in immature skeleton of children and adolescents. Literature search revealed that there are limited studies on this in Indian population. Purpose: The aim of the study is to enumerate the clinico pathological details of the patients with osteochondroma in a tertiary care centre over a period of 7 years. Materials and Methods: A retrospective descriptive study of seven years was conducted at a tertiary care hospital of South India from June 2015 – May 2022. Clinico pathological profile of 35 patients diagnosed with osteochondroma on histopathology were analysed. Epidemiological details of these patients were obtained from the hospital records. Results: 36 cases of osteochondromas from 35 patients were evaluated. 74.3% of the patients presented between 10 – 20 years of age. Male patients were predominantly affected, with OC seen in 74.3 % of them. 91.7% of the lesions were pedunculated. Solitary lesions were seen in 94.2% of the patients. Distal femur was the most commonly affected single bone (36.1%). Rare sites like scapula, rib, vertebra and pubic rami were affected in 22.2% of the cases. Conclusion: Osteochondromas are cartilage capped benign bone tumours affecting long bones of skeletally immature patients. Scapula being the third common bone affected in this study, OC should be considered in the differential diagnosis of bony scapular swelling. Centrally located OC can remain aymptomatic for long and present with malignant transformation.
