One-stage surgical excision of a huge bilateral multiple osteochondroma of the hip: a case report

Osteochondroma of Distal Femur Managed With Complete Excision: A Case Report

Osteochondromas are benign bone tumors that usually occur between the ages of 10 and 30, with no marked gender preference. These lesions result from the separation of the epiphyseal growth plate and are categorized as growth plate development abnormalities rather than true neoplasms. It is important to note that long-term solitary osteochondromas can evolve into osteosarcomas, with chondrosarcoma being the most common among them. However, the risk of recurrence is considerably reduced if the tumor is completely resected from its original site, with no residual perichondrium or cartilage cap left in place. In this context, a 29-year-old man with osteochondroma in the distal femur was successfully treated with complete resection, showing a favorable evolution.

Rare Presentation of Benign Osteochondroma: A Case Report

Introduction

Osteochondromas are the most common benign bone tumors (accounting for 20–50% of all benign bone tumors). They are developmental malformations rather than true neoplasms and are thought to originate within the periosteum. They usually affect bones that develop by enchondral ossification and rarely originate from bones that develop by intramembranous ossification such as the scapula, pubic rami, clavicle, and ribs.

Case Report

We present a case of a 24-year-old male, who came with a swelling in the right side inguinal region for 2 years which was diagnosed to be osteochondroma by trocar biopsy. The site and presentation are rare. The patient had no visceral or vascular involvement though the lesion was very near many vital structures on superior pubic ramus.

Conclusion

Osteochondroma arising from the pelvis is an unusual presentation which should be kept in mind as a differential diagnosis when evaluating mass in pelvis.
