A desmoid tumor is a locally aggressive growth of connective tissue origin which infiltrates the surrounding tissue and has a marked tendency for recurrence. And so it was also called as an aggressive fibromatosis, musculofascial fibromatosis or fibrosarcoma etc. Thirteen cases of desmoid tumor was treated since 1980, and their retrospective study was done with 79 months of follow-up after initial surgical excision. The female was involved in 12 cases(one male) with the age ranged from 7-50 years, average 28 years, and seven patients in third decade. A slowly growing mass was excised on average 4 months after first notice of the mass, but their margins are not demarcated clearly in most cases. Wide excision in 12 cases was done, but wide excision and saphenous vein graft was performed in one case because of invasion of posterior tibial artery by tumor mass. The tumor was found on extraabdominal region in 8 cases(61.5%) but 5 cases in abdominal wall(38.5%). The recurrence rate was high(6/13, 46.2%), and 11 times in 6 patients were recurred(average 1.8 times), within 27 months of initial excision. Six cases of recurrence were treated with wide excision again in 3 cases, wide excision combined with radiotherapy(4,000-6,000cGy) in 4 cases and wide excision with chemotherapy in one case. During the follow-up for average 21 months after treatment, no recurrences are found. Tumor remission periods without recurrence are average 67 months in all, and 11 years in longest case. Histologically it was very mimic with fibrosarcoma but could be differentiated with Trichrome stain, and their findings are not changed after recurrence.

Purpose: There have been limited reports on breast reconstruction after excision of phyllodes tumor. This paper reports four patients who had immediate reconstruction of the breast following excision of phyllodes tumor. Methods: We retrospectively reviewed the medical records of 14 patients from March 2000 to March 2008. Clinical data were analyzed including age, presenting symptoms and signs, type of surgery and metastasis. Results: The mean age was 38.6 years. The mean follow-up period was 40.6 months. Reconstruction was performed with latissimus dorsi musculocutaneous flap in 3 patients and transverse rectus abdominis musculocutaneous flap in 1 patient. Other cases were covered with skin graft or primary repair. 2 local recurrent cases were noted. Conclusion: The breast affected by phyllodes tumor must undergo complete excision. Followed by mastectomy, immediate reconstruction of breast improved cosmetic results, and allowed a wider surgical excision margin of tumor.

Clear cell hidradenoma is a skin adnexal tumor originating from eccrine glands. The risk of local recurrence after surgical resection exceeds 50%, and 6-19% of cases are malignant. The rarity of clear cell hidradenoma and its diverse histological findings make this type of tumor a diagnostic challenge. We present a case of recurrent clear cell hidradenoma of the posterior neck in a 70-year-old woman. The tumor recurred once after complete excision, and did not recur again after 1-cm wide excision and reconstruction with a local bilobed flap. Recurrent clear cell hidradenomas are activated by surgical stimulation, increasing the risk for metastasis. Therefore, we suggest that wide excision with confirmation of a tumor-free margin by frozen-section biopsy should be the first-line treatment for recurrent benign clear cell hidradenoma.

56 dogs that had undergone surgical excision of skin lesion tumors at Veterinary Medical Teaching Hospital in Seoul National University from 2000 to 2005 were evaluated retrospectively. The ratio of cases with benign versus malignant tumor types were 1.5:1.48 cases received surgical excision alone and 8 cases received adjuvant treatments. 42 cases were followed postoperative recurrence time and survival time (25 benign, 17 malignant). 25 cases (25/42, 60%) had no recurrence after surgical excision. In malignant tumor types, 5 cases (5/17, 29%) had recurrence and the median recurrence time was 157 days, and 8 cases (8/17, 47%) died due to tumors and survival time was 125 days. In benign tumor types, only 2 cases (2/25, 8%) had recurrence and the median recurrence time was 273 days.

Purpose: Clear cell hidradenoma, now regarded as an eccrine sweat gland tumor on the basis of its enzyme histochemical and electron microscopic features, occurs as a solitary tumor in most instances. Methods: A 17 year old male presented with asymptomatic nodule, which had developed on nipple with a four years of history and total excision and purse-string suture was then performed. Results: No recurrence was observed 2 months after excision. Histologically, it showed a well circumscribed tumor composed of characteristic clear epithelial cells which are focally arranged in glandular patterns. Conclusion: This case is unique in that the tumor developed on the young male nipple, unusual site and this report emphasizes the benefit of local excision to prevent recurrence of these tumor.

Giant cell tumor was described by Sir Astley Cooper in 1818. This tumor is considered to be a benign tumor but has problems of recurrence and metastatic change after treatment. Methods of operative treatment of this tumor have included currettage, currettage and bone graft, excision, resection, excision and graft and amputation. We experienced a case of giant cell tumor which involved the distal part of right radius and treated by wide excision and fibular graft. The postoperative courses have been satisfactory because of no recurrence or malignant change. After 6 years and 1 month follow up, the patient was able to return to daily life without any problem.

Purpose: Adenoid cystic carcinoma (ACC) is a rare malignant epithelial neoplasm derived from the salivary glands. In some cases, ACC may arise in other primary sites, such as skin. We report a case of adenoid cystic carcinoma arising the scalp skin of 69 - year - old woman. Methods: A 69 - year - old woman presented with a tender scalp nodule. A local wide excision was performed. Histopathologic examination was revealed the adenoid cystic carcinoma with basaloid cells in a cribriform pattern. The resection margins were free of tumor. Two years later a tumor recurred in the scarred area. The lesion was removed surgically and the histopathological diagnosis of adenoid cystic carcinoma was again established. After two years, tumor recurred again and diatant metastasis of the lung was diagnosed. A surgical wide excision was done and the close regular follow - up for recurrence was done. Two years later, third recurrence of the scalp was observed. We also performed the wide local excision with tumor free margin. Results: We experience the recurrent adenoid cystic carcinoma of the scalp with pulmonary metastasis. We have performed the wide local excision for three times. The patient has been followed up for 10 years with regular work - up for recurrence and metastasis Conclusion: primary cutaneous adenoid cystic carcinoma is a rare skin neoplasm with a high potential for recurrence after local excision. The standard treatment of ACC is wide local excision with tumor - free margins established by permanent section.

Purpose: Unplanned excision of a soft tissue sarcoma is defined as the operation performed for gross removal of a soft tissue sarcoma without regard for preoperative imaging or the necessity to removal a margin of normal tissue covering the cancer. We report our experience of treating primary soft tissue sarcoma after an unplanned excision. Materials and Methods: We retrospectively reviewed 31 patients referred to our hospital after unplanned excision at other hospitals for treatment of a STS. The clinical information was reviewed with a focus on the patient's age, gender, tumor location, tumor size, tumor depth, presumptive diagnoses at the previous surgery, refer hospital, definitive diagnosis, interval between the initial and additional surgery and local recurrence. Results: There were 19 males and 12 females with a median age of 48 years (range, 17-75 years) at the time of referral. Seventeen patients (54.8%) had tumors in their lower limb, 6 (19.4%) had tumors in their upper limb, and 8 (25.8%) had tumors in their trunk. Tumor depth could be determined for 8 patients (25.8%), with superficial and 22 deep tumors (71%). The medial interval between unplanned excision to re-excision ranged from 2 weeks to 1 year (median, 5 weeks). Local recurrence was detected in 2 patients. All patients were alive without metastasis at last follow up. Conclusion: Even in upper class general hospital, many unplanned excision had been performed, which is considered to be avoided. When the relatively huge mass located in deeper layer it requires enough preoperative imaging studies and biopsy.

This is a clinical analysis of 24 cases of parotid gland tumor who were treated in the department of Surgery, Chonnam National University Medical School during the past 10years from January, 1976 to December, 1985. According to this analysis of total 24 cases, we concluded as follows; 1) 21 cases were benign tumors and 3 cases were malignant tumors. As the histopathological findings, benign tumor included 88%and malignant tumor 12%. Majority of benign tumor contained mixed tumor(86.7%), and the malignant tumor contained mucoepidermoid carcinoma (66.7%). 2) The peak age incidence was 40th in benign tumor and 50th in malignant tumor. 3) The chief complaints of patient was a painless mass and the duration of illness was average 5.2 years. 4) The mean size of mass was 4.5cm in diameter. 5) The surgical procedures were performed with excision 6 cases, superficial lobectomy 8 cases, wide excision with partial parotidectomy 4 cases, total parotidectomy 3 cases in benign tumors. In malignant tumors, total parotidectomy 2 cases and wide excision with partial parotidectomy 1 case were performed. 6) Major postoperative complications such as facial nerve palsy 7 cases (temporary ; 5 cases, permanent; 2 cases), Frey syndrome 1 case, seroma 1 case, hematoma 1 case, and wound infection 1 case were developed. The recurrence contained pleomorphic adenoma 1 case and mucoepidermoid carcinoma 1 case.

Purpose: Dermatofibrosarcoma protuberans is a rare tumor, accounting for 0.1% of all malignant tumors. Although metastasis is very uncommon, local recurrence occur frequently. Dermatofibrosarcoma protuberans occurring in children is even more rare; this is the first case report of congenital dermatofibrosarcoma protuberans in Korea. Methods: The patient is a 14-month-old male infant with a lesion that was first thought to be a birthmark. The lesion grew larger, and a punch biopsy revealed dermatofibrosarcoma protuberans. A wide local excision was performed with a 2 cm peripheral resection margin beyond the gross tumor lesion. Deep fascia and a portion of muscle underneath the central part of the lesion were also taken. The surgical defect was covered by a split-thickness skin graft. Results: There has been no clinical sign of recurrence over one year after the surgery. Conclusion: A patient with congenital dermatofibrosarcoma protuberans detected at an early stage underwent a wide local excision of the tumor after accurate diagnosis was carried out by biopsy and immunohistochemical studies. There was no clinical evidence of tumor recurrence during over a 1-year follow-up.
