This is a descriptive observational study based on review of cases of solitary osteochondroma (OC) excised in the last 20 years at JPMC Karachi. The purpose of this study was to evaluate the clinico-radiological presentation and the complications that warranted excision of these benign tumors and also to know the number of malignant transformation. The material included case sheets, available x-rays, histopathology reports. Excluded were the cases of multiple osteochondromatosis, diaphyseal achalasia, enchondromas and patients` age <5 years. Patient whose report showed malignant transformation were called by special messenger. A total of 78 solitary osteochondroma were excised. Age range of these patients was 7-30 years except one whose age was 60 years. Average age was 17.30 years in males and 16.1 years in females. Male vs. female ratio was 2:1. Flat bones (Ilium & scapula) were involved in 8 cases and long bones in 63 cases. Other rare site included phalanges (2), metacarpals (2), clavicle (1), greater trochanter (1) and talus (1). Malignant transformation warranted excision in 5(6.4196) cases that was in elder age group. The rapid growth of tumour during growth spurt period was the commonest (78.2%) presentation warranting excision in teenagers and adolescents. The other common presentation (38.46%) that warrant early excision in younger age group was development of deformity when tumour occurred is L either of two distal radius / ulna or distal tibia/fibula. The other presentation warranting excision was neurovascular complications that were mostly around knee joint (16.66%), distal radius and upper humerus. All the patients remained well following excision and none has reported recurrence.
