title: Congenital Extraskeletal Osteochondroma of the Web Space Displacing the Lesser Toes: A Unique Presentation.
abstract: Extraskeletal osteochondroma is a rare benign tumor that occurs predominantly in the soft tissues of the hands and feet. The congenital occurrence of this lesion in children is very rare. We report the case of a 9-year-old male who presented with slowly progressive swelling in his left third web space since birth that was painful with prolonged walking and had displaced his fourth toe further laterally, causing both functional and cosmetic problems. Radiographs and computed tomography revealed a well-circumscribed densely ossified lesion. Excision biopsy of the lesion showed a lobulated extraskeletal osteochondroma. At the end of 1 year of follow-up, the child had had no recurrence. To the best of our knowledge, this is the first report of congenital extraskeletal osteochondroma of the foot in English-language published studies.
