chondroblastoma of the acromion: a case report and review of the literature

Chondroblastomas are rare benign neoplasms and scarcely present in the acromion. we reported a case of chondroblastoma presented in the right acromion of a 36-year-old male. the patient had pain and restricted abduction. moreover, the histological analysis of the biopsy sample was consistent with the diagnosis of chondroblastoma. the patient was treated with extended curettage and bone grafting. besides, the 2-year follow-up of the patient was event-free. this case reveals that the chondroblastoma of acromion can be adequately treated by extended curettage. it also highlights the importance of acromion chondroblastoma in the differential diagnosis of shoulder pain to avoid the undertreatment of the patients.
