수지에 발생한 조갑하 외골종 -증례 보고-
Subungual exostosis is a benign tumor of the distal phalanx occurring beneath or adjacent to the nail. It is usually solitary lesion that most often in the substance of the great toe. It rarely occurs in the fingers. The majority of the lesions occur in the second and third decade of life. A 27-year-old adult with subungual exostosis of his left 3rd finger is presented. A major clinical manifestation is a firm, fixed growing nodule. Removal of the deformed nail and complete resection of the mass from the distal phalanx produces a useful finger without pain, or resultant nail deformity. At 1-year follow-up, the result was excellent, with no sign of recurrence. We hope this report will improve awareness of subungual exostosis of the finger.
