We reviewed the clinical features of 2 patients who underwent surgery for subungal exostosis, focusing on postoperative deformity of the nail. The lesion destroyed the nail bed and was excised with a direct approach. then thin split-thickness sterile matrix graft was done after excision of the tumor because the defect of the nail bed was large. Good postoperative appearance of the nail was obtained by thin split-thickness sterile matrix graft. The use of thin split-thickness sterile matrix graft for the replacement of a nail bed defect can regain a smooth, adherent, and normal-looking nail and avoid donor-site morbidity. Thin split-thickness toe-nail bed graft is a good choice for the prevention of postoperative deformity.

Subungal exostosis is a rare benign cartilaginous tumor affecting the distal phalanx. From 1995 to 1996, six subungal exostoses of the hallux were treated in the Chonnam national university hospital. The symptoms were subungal pain, mass on the distal phalanx elevating the nail or causing ulceration of the nail bed. The plain radiological examination showed a bony mass occurring on the dorsomedial or medial aspect of the distal phalanx. The diagnosis of the subungal exostosis of the hallux were suspected from clinical presentation and confirmed with radiographic examination. Histological patterns were fibrocartilaginous cap with the mature trabecular bone. Complete excision of the lesion including overlying nail bed was curative without recurrence in all cases.

Osteochomdromas, which are uncommon in the hand, are encountered most frequently with hereditary multiple exostosis. They can occur away from the epiphyseal plate region at the distal end of the proximal and middle phalanges. But little has been written about exostosis that occur at the distal end of the distal phalnges. We report one case of hereditary multiple exostosis that arose at the distal end of the distal phalnges. Complete excision was done and the patient was disease-free of 4 years follow-up.

Purpose : This study was conducted to analyze the clinical materials and treatment results of 13 cases of subungual exostosis. Materials and Methods : Thirteen subungual exostoses of the foot treated from January 1991 to December 1997 were studied. We analyzed the clinical data and results of treatment to identify the clinical characteristics of this disease. We investigated the location, shape and relation of exostosis to phalanx with simple x-ray of the foot to identify the radiological characteristics. All the cases were sent to pathologic examination after resection to determine the pathological characteristics. Results : The results of physical examination on presentation were various. Most cases were located at the dorsomedial side of the distal phalanx and were involved in the toe nail. Eleven cases were located at great toes and one each at the 2nd and 3rd toe. Causes of exostosis were not clear, but 2 cases were related to trauma. For the type of exostosis, 7 cases were sessile and 6 were stalk type. On histologic examination, 9 cases showed a cartilaginous portion with overlying proliferating fibrous tissue and underlying bone formation. There was a gradual maturation of spindle cell proliferation from cartilage to cancellous bone. The cartilage was moderately cellular with some pleomorphism, but true anaplasia was not present. Conclusion : The clinical presentation and findings of simple x-rays were most helpful in diagnosing subungual exostosis. Complete excision of the mass achieved complete relief of symptoms and recovery without recurrence in all cases.
