Background: Reporting a case of osteochondroma in an uncommon location in a pediatric patient.

Presentation of Case: A female patient with a history of limited pronation in the right forearm due to a solitary lesion in anterolateral part of distal third of the ulna, features suggesting ostechondroma both in imaging and histopathology.

Discussion: Distal ulnar exostosis are described in the literature in relation with multiple hereditary exostoses disease and deformities in ulna or both forearm bones requiring a surgical intervention but a solitary isolated forearm exostosis is rare.

Conclusion: Osteochondromas in the forearm are rare but they should be considered in the differential diagnosis if features are suggesting it.
