Subungual exostosis (SE) is a relatively uncommon benign bone tumor that occurs in the distal phalanges of the toes or fingers.
An 8-year-old girl presented for treatment of an acquired mass on the distal right index finger. The patient was preoperatively diagnosed with a benign bone tumor. Surgical resection of the distal right index finger mass was performed under general anesthesia, and histological examination of the resected tissue supported a diagnosis of SE of the right index finger. The surgical outcome was good, with no surgical site infection. Throughout 15 months of follow-up, the patient was asymptomatic with no recurrence.
Surgical resection of a mass on the distal right index finger resulted in absence of recurrence during 15 months of follow-up. SE is a benign and uncommon lesion that is infrequently encountered by physicians. This infrequent occurrence may result in delays in diagnosis and treatment. Complete excision of the lesion and careful separation from underlying nail bed structures results in total resolution of the lesion, while providing the lowest risk of recurrence.
甲下外生骨疣（SE）是一种相对罕见的良性骨肿瘤，发生于脚趾或手指的远端指骨。
一名8岁女孩因右手示指远端出现后天性肿物前来治疗。患者术前被诊断为良性骨肿瘤。在全身麻醉下对右手示指远端肿物进行了手术切除，切除组织的组织学检查支持右手示指SE的诊断。手术效果良好，无手术部位感染。在15个月的随访期间，患者无症状且无复发。
对右手示指远端肿物进行手术切除，在15个月的随访期间未出现复发。SE是一种良性且罕见的病变，医生很少遇到。这种罕见情况可能导致诊断和治疗延迟。病变的完整切除以及与下方甲床结构的仔细分离可使病变完全消退，同时复发风险最低。
