Although it is thought to be a relatively common tumour, only 34 positively identified cases of subungual exostosis in the hand have been found in the literature to date. 16 further cases are reported, making this the largest published series. Seven cases presented with an incorrect diagnosis. An X-ray easily differentiates the tumour from an osteochondroma of the distal phalanx, a spike of bone from a crush injury, or a response to a penetrating injury called a turret exostosis. Removal of the deformed nail and excision of the mass from the distal phalanx produces a useful finger without pain, tender scar, or resultant nail deformity. No case of malignancy has ever been reported.
尽管人们认为它是一种相对常见的肿瘤，但迄今为止，文献中仅发现34例手部确诊的甲下外生骨疣病例。本文报告了另外16例病例，使其成为已发表的最大病例系列。7例病例最初诊断有误。X线检查可轻松将该肿瘤与远端指骨的骨软骨瘤、挤压伤所致的骨棘或穿透伤引起的一种称为炮塔状外生骨疣的反应相鉴别。切除变形指甲并从远端指骨切除肿物后，手指功能良好，无疼痛、压痛性瘢痕或指甲畸形。从未有过恶性病例的报道。
