Purpose: To compare clinical characteristics of ganglions in hand & Foot. Materials and Methods: Seventeen cases of ganglions located in foot and fifty-five cases in hand. Excised from Mar.1988 to Apr.2003, were included in the study. The clinical characteristics and recurrence ratio were evaluated Results: The mean size of 2.2 cm in hand and 2.5 cm in foot. The most common area of ganglions are dorsum of foot and wrist. The cosmetic problem of palpable mass is the primary chief complaint of ganglions on hand and the pain is that of foot. The recurrence was found in 5 cases in hand and 4 cases in foot. The recurrence was related to incomplete excision of ganglion in foot and the large size of ganglion and incomplete excision of ganglion in hand. Conclusion: recurrence ratio in the cases of foot is higher than that of hand. The ganglions in foot and hand need to treated by meticulous surgical excision to prevent the recurrence.

Polydactyly is the most common congenital deformity of the foot. The authors present an unusal case of polydactyly of the foot in an otherwise healthy adult male. The patient has an mixed type of polydactyly composed of polysyndactyly of the first toe, Y shaped second metatarsal and polysyndactyly with the fusion to the forth toe of the fifth toe. Meticulous. preoperative plan was prepared and performed at the operation. Main procedures were as follows : 1) Excision of extradigit of first toe and first metatarsocuneiform joint fusion. 2) Excision of lateral bud of second metatarsal and plantar-medial osteotomy of the medial bud. 3) Metatarsal head resection arthroplasty of third & forth metatarsophalangeal joint and 4) Excision of medial polydactyly of the fifth toe and syndactyly release and split thickness skin graft. Postoperatively, The forefoot width was reduced from 11.5 to 9.5cm and the pain was relieved.

The Z-plasty has been known as a most common surgical treatment of congenital circumferential constriction band syndrome of the hand. There were thirteen patients of congenital circumferential constriction band syndrome of the hand. All patients underwent Z-plasty under microscope. we did microsurgical dissection to minimize vascular, neural and lymphatic injury, and then considering secondary correction and scar contracture, tried to preserve as much subcutaneous fat and skin flap as possible without any excision. There were less skin necrosis and lymphedema as a result of vascular compromise. Using microscope offers several advantages. First, preventing vascular, neural and lymphatic injury. Second, getting an accurate suture approximation. finally, preserving as much subcutaneous fat and skin flap as possible without any excision. The outcome of digit growth and contour can be excellent than we expected. As a results, we believe that correction of congenital circumferential constriction band syndrome of the hand under the microscope have better results.

A 54-year-old female presented with a 4cm sized painless, submandibular gland area mass. Vascular lesion was suspected in computed tomography scan. Surgical excision was performed via retroauricular approach for its excellent cosmetic outcome. The vascular mass with peripheral focal calcification was clearly resected without complication such as bleeding or neural damage. Histopathological examination of the specimen revealed an arteriovenous malformation(AVM) with abnormal communications between arteries and veins without the normal intervening capillary bed. We report a successful excision of AVM in the submandibular space via retroauricular approach.

Purpose: Facial nerve injury is a rare but feared complication of face lift. Uncertainty as to the depth and vulnerability of the facial nerve in face lift dissection causes some surgeon, particularly novices, to dissect slowly. Excessively thin flaps can be made because of fear of nerve injury, contributing to skin slough. Methods: From September 1998 to February 2003, the authors operated on 34 aging face patients using classical face-lift. We had analysed about quantity of skin removal and degree of elevated flap. The authors have found quantity of skin removal was 1.5-2.0 cm, degree of elevated flap was 40-45 degree on average. Results: The authors performed preauricular pre-excision face-lift technique on 12 aging face patients from July 2003 to Feburary 2005 based on experienced surgery. This technique reduced fear of dissecting skin flap necrosis and facial nerve injury because of firmly attached pre-auricular skin removed in advance. Conclusions: We easily dissected SMAS without visual field disturbance, nerve damage and reduced operation time and bleeding loss compared to classical face-lift.

Extramammary Paget's disease (EMPD) is a rare, slow-growing intraepithelial malignancy that mainly involves the genital region, including the vulva, penis, scrotum, perianal, and periurethral areas. Although several treatment options exist, wide local excision with a safe margin is considered the treatment of choice. After resection of the lesion, it is often challenging to reconstruct the defect because defects in the perineal region require adequate volume for protection and are susceptible to infections, which is a particularly significant risk for large defects. We report a case of perivulvar EMPD that was reconstructed with three-directional local flaps after wide excision of the tumor. We covered the defect sequentially using the following 3 flaps: a gracilis myocutaneous flap from the left thigh, a bipedicled V-Y advancement flap from the lower abdomen, and an internal pudendal artery perforator-based island flap from the right buttock. To the best of our knowledge, this report is the first to describe a three-directional approach to extensive perivulvar reconstruction.

Side effects of tattoos can occur due to unexpected body responses. Concerns about the side effects of tattoos are growing concomitantly with the increasing number of tattooed individuals. We report a rare case of basal cell carcinoma (BCC) on a tattooed eyebrow. A 48-year-old woman with no family history or occupational risk of skin cancer had her eyebrows tattooed 6 years prior, and she noticed a black mass on her right eyebrow 1 year before presentation. Staged excision was planned due to the patient's reluctance regarding the possibility of a wide scar. After the first surgical procedure, a histopathological examination confirmed BCC. Wide excision and primary closure were performed for remnant BCC, and no recurrence was observed. The mechanism of skin neoplasms involving tattoos has not been clearly identified. Unapproved tattoo inks contain carcinogenic substances, and previous case reports indicate that skin neoplasms may differ depending on the tattoo color. Therefore, the carcinogenic effects of these unknown components of tattoo ink might cause skin neoplasms. Accurate component analysis and systematic management of tattoo ink is necessary, and medical practitioners must also pay attention to this possibility because it is easy to overlook tattoos as a causal factor contributing to cancer.

Purpose: Malignant fibrous histiocytoma (MFH) is mainly a soft tissue sarcoma containing fibroblast-like cells and histiocytic cells. MFH in bone accounts for 5% of all malignant bone tumors. MFH of the maxilla is extremely rare and difficult to diagnose due to its scarcity. Treatment mainstay is a complete surgical excision. Radiation therapy is also available when surgery alone is incomplete. Prognosis is not clear but can be devastating. Authors report one case of MFH developed in the maxilla. Methods: A 24-year-old man firstly diagnosed as fibrous dysplasia based on CT findings. Considering facial contour, partial excision was done. But pathology report confirmed malignant fibrous histiocytoma and secondary wide excision was done including zygoma and grossly all affected area. After surgery, radiation therapy was continued. Results: There are no evidence of tumor recurrence after clinical and radiological treatment. Conclusion: MFH of maxilla is very rare and this can leads to misdiagnosis in many clinicians. Surgeon should differentiate this disease from fibrous dysplasia and pathology and MRI are accurate methods for diagnosis of MFH.

This report documents the clinical k pathologic features of 33 patients treated for thymoma for 11 years & 6 months between September 1977 and February 1989. At the Thoracic & Cardiovascular Surgery, Yonsei University, College of Medicine of the group, 31 patients treated with surgery were examined for the result of operation & prognosis. Mean age was 50 years. Thirteen were female and twenty were male. Dyspnea on exertion and chest discomfort were common in the patients without myasthenia gravis. Fourteen patients[42.6%] had myasthenia gravis and one patient had autoimmune thyroid disease. Four patients[12.1%] presented without symptoms attributable to their thymoma. Histologic review disclosed 12[36.4%] epithelial thymoma, 10[30.3%] mixed lymphoepithelial, 9[27.3%] lymphocytic, 1[3.0%] spindle cell and 1[3.0%] unknown cell thymoma. They were classified according to Masaoka`s clinical staging criteria; by these criteria, 8 patients were stage I, 5 patients were stage II, 15 patients were stage III and 3 patients were stage IV. Total excision of mass was possible in 20 patients. Partial excision of mass in 4 patients and biopsy in 7 patients were carried out during the operation. There was only one operation mortality. Follow-up was possible in 26 patients and follow-up ranged from 4 months to 10.5 years[mean 28.9 months]. One-year survival rates were 77.8% and eight patients expired during follow-up period. Eleven[78.6%] patients with myasthenia gravis were improved after the operation. This observation suggests that the most significant factor determining the survival is whether or not total surgical excision had been performed.
