Osteoid osteoma (OO) is a benign osteoblastic bone tumor typically involving the diaphysis or metaphysis in long tubular bones. OO in phalanges of the great toe has been rarely reported, and it is often challenging to differentiate with subacute osteomyelitis, bone abscess, or osteoblastoma. This case report describes an uncommon case of a 13-year-old female patient with subperiosteal OO in the proximal phalanx of the great toe. The atypical location of OO should be familiarized to include appropriate differential diagnosis and to ensure accurate diagnosis by radiologic evaluations. Surgical excision remains the benchmark for the treatment of OO with its advantages on direct visualization and histologic confirmation for the diagnosis.
骨样骨瘤（OO）是一种良性成骨细胞瘤，通常累及长管状骨的骨干或干骺端。发生于大脚趾近节趾骨的 OO 较为罕见，且其与亚急性骨髓炎、骨脓肿或骨母细胞瘤的鉴别具有挑战性。本病例报告描述了一例罕见的 13 岁女性患者，其大脚趾近节趾骨发生骨膜下 OO。应熟悉 OO 的非典型位置，包括进行适当的鉴别诊断，并通过影像学评估确保准确诊断。手术切除仍然是 OO 的治疗金标准，其具有直接可视化和组织学确认诊断的优势。
