A unique case of multiple osteochondroma: Mandibular symphysis and femur
A 13-year-old Nigerian boy was referred to our unit by the orthopedic department for evaluation of a hard swelling on the right chin region. The patient was found to have a bony hard swelling on his left thigh region. A plain radiograph showed a bony exostosis near the distal femur (Figures and ). On examination of the facial region, a painless bony hard swelling was found on the right submental region. The patient had noticed these swellings one year back. A three-dimensional computed tomography (CT) showed a sessile bony protuberance of the right symphysis region []. Detailed case history revealed no other family members to have similar bony outgrowths. Due to the age of the patient and site of the swellings, a clinical diagnosis of osteochondroma was made. Simultaneous excision of both the tumors was done under general anesthesia by orthopedic and maxillofacial surgeons. The tumor at the symphysis region was exposed through an intraoral approach []. The tumor was excised using surgical burs and chisels [Figures and ]. The tumor measured 15 mm in length and 10 mm in diameter []. The tumor from the femur region measured 35 mm in length and 30 mm in diameter. Histopathological examination [] of both tumors confirmed the clinical diagnosis of osteochondroma. Patient was free of recurrence till 6 months after surgery.
