Subungual exostosis is an uncommon bony tumor of the distal phalanx most often seen on the hallux. Although this lesion is completely benign, it must be distinguished from a number of other subungual tumors, both benign and malignant. Radiography of the digit is a noninvasive test that should be part of the initial workup whenever subungual exostosis is in the differential diagnosis. Once identified, surgical removal of the exostosis generally is both effective and well tolerated. We present a case of subungual exostosis that was discovered incidentally during a full-body skin examination. We also review the pertinent clinical and histopathologic findings, diagnosis, and treatment of this entity.
甲下外生骨疣是一种罕见的末节指骨骨肿瘤，最常见于拇趾。尽管此病变完全良性，但必须与其他多种甲下肿瘤相鉴别，包括良性和恶性肿瘤。手指的X线摄影是一种非侵入性检查，在甲下外生骨疣的鉴别诊断中，应作为初始检查的一部分。一旦确诊，手术切除外生骨疣通常既有效且耐受性良好。我们报告一例在全身皮肤检查时偶然发现的甲下外生骨疣病例。我们还回顾了该疾病的相关临床和组织病理学表现、诊断及治疗。
