Abstract

Abstract : Osteochondroma is one of the most common benign bone tumors; however, as it rarely affects any bones in feet, it may easily escape detection without rigorous examination. We present an exceptionally rare case of tarsal navicular dorsal osteochondroma diagnosed in an 11-year-old female child affected by chronic foot pain. Radiographs, MRI, and computed tomography scan revealed bony excrescences extending outward from the navicular bone. After conservative treatment failed, the navicular dorsal exostosis was excised in open surgery with complete resolution of symptoms. Navicular–cuneiform impingement was diagnosed by instrumental and intraoperative techniques. Histological analysis confirmed the diagnosis of navicular dorsal osteochondroma. This case report illustrates the necessity of particularly rigorous evaluation of the substrates of pediatric chronic foot pain.
