Enchondromas are common in the hand but less frequent in the distal phalanges. Epidermal cysts are rare in the hand but when they occur can be difficult to differentiate from enchondromas both clinically and radiologically. Our review of seven distal phalangeal bone lesions treated over 7 years included four enchondromas and three epidermal cysts. The patients with epidermal cysts all had a history of previous penetrating trauma 5-8 years earlier. One patient with an enchondroma had a history of a penetrating injury. Patients presenting with distal phalangeal lesions and a history of previous penetrating injury appear more likely to have an epidermal cyst than an enchondroma. This is important as there may be a higher recurrence rate following curettage and bone grafting.
内生软骨瘤在手部较为常见，但在远端指骨中较少见。表皮样囊肿在手部罕见，但一旦发生，在临床和放射学上都难以与内生软骨瘤相鉴别。我们回顾了7年间治疗的7例远端指骨骨病变，其中包括4例内生软骨瘤和3例表皮样囊肿。表皮样囊肿患者均有5 - 8年前的既往穿透性创伤史。1例内生软骨瘤患者有穿透伤史。出现远端指骨病变且有既往穿透伤史的患者似乎比内生软骨瘤更易患表皮样囊肿。这一点很重要，因为刮除术和骨移植后可能有更高的复发率。
