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.

목적: 지방종성 종양은 수부에서 발생하는 경우는 드문 것으로 알려져 있다. 저자들은 수부에 발생한 지방종성 종양 11예를 수술적으로 치료하였기에 그 임상적 특성을 보고하고자 한다. 대상 및 방법: 1992년부터 2008년까지 수부종양으로 수술받았던 환자 중 조직학적으로 지방종성 종양으로 진단받은 환자를 선별하였으며 후향적으로 그 특성을 조사하였다. 의무기록 및 방사선학적 검사 그리고 수술전후 사진기록을 조사하였다. 재발여부는 전화면담을 통해 확인하였다. 결과: 11예 중 8예가 지방종이었으며 비전형 지방종(atypical lipoma)가 1예, 조갑하 혈관 지방종(subungal angiolipoma)가 1예, 섬유지방종(fibrolipoma)이 1예이었다. 발생부위로 수지에 발생한 경우가 4예이었으며 무지구근부 2예, 소지구근부 2예, 수장부 1예, 손목 2예이었다. 전례에서 수장부에 발생하였다. 증상으로 대부분 종물감을 호소하였으며, 통증이 동반된 경우는 2예, 감각이상을 호소한 경우가 1예 있었다. 통증이 있었던 2예 중 1예는 조갑하 혈관지방종이었고 1예는 수장부에 발생한 단순 지방종이었다. 비전형 지방종은 2 cm 가량의 주위조직을 포함한 광범위 절제를 시행하였고, 나머지 10예에서는 단순 절제를 시행하였다. 술 후 합병증으로 지방종의 크기가 5 cm이상으로 수술 후 수술부의 원위부에 감각저하 및 수술 절개부에 과감각을 호소하는 경우가 1예 있었고 기타 다른 합병증은 없었다. 전화면담이 가능했던 10예 중 재발은 없었다. 결론: 수부에 발생하는 지방종성 종양은 대개 종물감외에는 증상이 없으나 드물게 통증이 나타나는 경우가 있었다. 육안 소견은 비슷하나 조직의 성상은 다양하였다. 수술을 할 경우 합병증의 위험은 적으나 종괴가 클 경우 수술 중 신경손상의 위험이 있으므로 세심한 수술을 해야 할 것으로 사료된다.

Nail bed malignancies are rare entities. Most nail bed malignancies are squamous cell carcinoma (SCC)s. Less than 10% of subungual SCCs occur in the foot. Fifty percent occurred on the hallux and approximately 25% on both the fourth and fifth digits. The correct diagnosis is often delayed because nail bed malignancies are frequently mistaken for benign or infectious processes. SCC on extremities is hard to distinguish from the benign lesion like chronic ulcer, fistula caused by chronic osteomyelitis, and abscess fistula. Attention should especially be paid in diagnosing the subungual lesion because paronychia is a common disease. SCC is the most common carcinoma second to malignant melanoma as a soft tissue malignant tumor in the West, and it involves mainly the head, neck and upper extremities but rarely involves lower extremities, particularly the toes. The authors emphasize the importance of a biopsy for chronic nonhealing lesions by presenting this case.

A subungual exostosis is an uncommon benign osteochondral lesion that appears as a painful nodule. Histologically, the tumors consist of a proliferating fibrocartilaginous cap that merged into mature trabecular bone at its base. From 1989 through 1991, 5 patients with subungual exostosis were treated. Three of them had exostosis on the great toe. There were three girls and two boys. The average age of the patients was 10.6 years. All of patients were treated by local excision. Two cases of our patients treated with an incomplete excision were recurred within 3 months after the original procedure. Lack of awareness of unusual lesion can cause initial misdiagnosis in many cases. We considered that a complete excision of the lesion is important for preventing the recurrence, and it should be confirmed with intraoperative radiographs.

Purpose: Subungual squamous cell carcinoma is a very rare malignant tumor of the digitus especially in toe making it very difficult to differentiate with tinea unguium, verruca vulgaris, eczema, pyogenic granuloma, and malignant melanoma due to their clinical similarities. Therefore this article reports on subungual squamous cell carcinoma of left 5th toe. Methods: A patient visited at our hospital due to pain and incurable inflammation on left 5th toe with no improvement for four months. Despite of antibiotics and dressing for a week, treatment was ineffective. After excisional biopsy, he was diagnosed with subungual squamous cell carcinoma. And ray amputation and prophylactic inguinal lymph node dissection was done. Results: The biopsy was showed irregular cells made up of anaplastic and squamous cells in the dermis and epidermis. And the inguinal lymph node showed no metastatsis. The patient had been treated without significant complications and recurrence for a year. Conclusion: This article emphasizes the need of diagnostic biopsy on the subungual lesions that have resistance to the conventional treatments. And if that is subungual squamous cell carcinoma, complete resection of the lesion and prophylactic inguinal lymph node dissection is essential.

Yellow nail syndrome is a rare cause of pleural effusions. This syndrome is characterized by yellow discoloration of nails, lymphedema, and respiratory disorders, including pleural effusion, chronic bronchitis, bronchiectasis, and chronic sinusitis. The etiology of this syndrome is obscure, but the pathogenesis seems to be related with impaired lymphatic drainage. We report a case of yellow nail syndrome in a 70-year-old female with the typical clinical findings (yellow discoloration of nails, lymphedema, and chronic pleural effusion) of this disorder and with proven lymphatic obstruction on lymphoscintigraphy.

Purpose: Pincer nail is a relatively rare deformity characterized by an increase in transverse curvature along the longitudinal axis of the nail. This curvature commonly increases from proximal to distal end of nail, leading to pinching, curling, and distortion of the underlying soft tissue and resulting frequently in severe pain. Numerous surgical procedures have been reported. Preserving the width of the nail in the correction of the pincer nail is very important for functional and aesthetic reasons. We report the results of the correction of the pincer nail using autogenous dermofat graft with a good result. Methods: From May 2006 to September 2008, dermofat graft was performed in 6 patients with pincer nail. Patients were four women and two men, and the average age was 51. The affected digits were the unilateral great toes in four patients and the unilateral thumbs in two patients. Average follow-up period was 13 months. Surgical procedure was removal of nail using an elevator to avoid damage to the nail bed. An incision was created in distal portion of hyponychium. Paronychium was dissected from distal phalanx by periosteal elevator through incision of hyponychium and tunnel was made. Then dermofat grafts harvested from inguinal area were inserted into the tunnel. Finally, a silicone sheet was inserted eponychial fold for prevention of synechia. Objective assessment was evaluated by use of the width index and height index. Results: All patients reported resolution of the pain and soft tissue pinching sensation that they had before the operation. There was good adherence between the nail plate and the underlying nail bed. The nails have regrown and were corrected in a normal and flattened appearance. The width index and height index were improved. Conclusion: The autogenous dermofat graft seems to provide an effective treatment of the pincer nail with preservation of the nail matrix.

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.
