Abstract
Osteochondromas (OC), or exostoses, are developmental defects rather than true neoplasms. Misdirected physeal bone growths give rise to OC. It causes cartilage-capped bony extensions to emerge from the lateral outlines of endochondral bones. We discuss a case of OC in a 35-year-old female who presented with severe chest wall deformity and breathlessness due to compromised left lung function. CT scan showed a vast osteochondroma arising from the ventral surface of the scapula, which was palpable in the supra mammary region on the left side. The tumor mass was completely excised from the base of the stalk. Her breathlessness and compromised left lung function returned to normal in the post-op period. However, the chest deformity was corrected over two months. The article provides insights into the presentation in a patient with such a massive tumor due to its location. Surgical excision should be the treatment of choice for huge osteochondromas.
