Radiological examination showed right anterior tibial, mid diaphyseal lytic expansile lesion with internal trabeculations and excisional biopsy led to the diagnosis of adamantinoma. Below knee amputation was done as a definitive management.Conclusion: Despite diagnostic challenges adamantinoma presents, the patient was referred to oncology and underwent amputation, underscoring the importance of considering adamantinoma in differential diagnosis for persistent bone lesions.Keywords: adamantinoma, bone tumor, Ethiopia
