Purpose: Nerve injury is one of the complication which can develop after brow lift. Peripheral nerve ending which is stretched from supraorbital nerve and supratrochlear nerve can be injured and symptoms such as pain, dysesthesia may appear. Usually, developed pain disappeared spontaneously and does not go on chronic way. We experienced a case that a patient complained chronic pain after brow lift which was not controlled by conservative management such as medications, local nerve block and report a successful surgical treatment of chronic pain after brow lift. Methods: A 24-year-old male who received brow lift with hairline incision at local hospital was admitted for chronic pain at the right forehead. The pain was continued for 3 months even though fixed thread was removed. Local nerve block at trigger point with mixed 1 mL 2% lidocaine and 1 mL Triamcinolone acetonide was done and oral medications, Gabapentine and carbamazepine, were also applied but there was no difference in the degree of pain. Therefore the operation was performed so that careful dissection was carried out at right supraorbital neurovascular bundle and adhered supraorbital nerve was released from surrounding tissues and covered with silastic sheet to prevent adhesion. Results: The pain was gradually relieved for a week. The patient was discharged without complications. No evidence of recurrence has been observed for 2 years. Conclusion: The pain developed after brow lift was engaged with nerve injury and sometimes remains chronically. Many kinds of conservative management to treat this complication such as medications, local nerve block have been reported and usually been used. But there are some chronic cases that conservative treatment do not work. In sum, we report 1 case of successful surgical treatment for relief of intractable pain developed after brow lift surgery.

In this present study, the healing process and the recurrence of pigmentation were evaluated clinically and histologically in accordance with the extent and the range of pigmentation after phenol was applied to remove melanin pigmentation in gingiva. Six mongrel dogs were used. The melanin pigmentation in canine gingiva were classified into slight, moderate and severe according to the extent of pigmentation and divided into local and diffuse types according to the range. Following general and local anesthesia, 90% phenol was applied to the pigmented gingiva of the subjects with small cotton balls until the surface was etched to be whitish and was neutralized with small cotton balls soaked by 95% alcohol. The contralateral pigmented gingiva to the one treated with phenol, was treated by surgical deepithelialization. At 1, 3 and 8 weeks, the treated gingiva was examined clinically and evaluated histologically following H-E stain, and HMB 45 stain for melanocyte after biopsy. In the phenol treated sites, epithelium and connective tissue healed normally and there was no pigmentation at 1 week. At 3 weeks of healing, melanin repigmentation was observed in the severe local type and moderate to severe diffuse type. In the surgically deepithelialized sites, healing was delayed, compared to phenol treated sites and the infiltration of the inflammatory cells and congestion in connective tissue was shown at 1 week. At 3 weeks, healing was completed and there was a partial melanin repigmentation. At 8 weeks of healing, the extent and the range of repigmentation were increased in both group according to the extent or range priot to depigmentation procedure. These results suggpriorest that the removal of melanin pigmentation with 90% phenol application result in normal healing process of gingiva. However, in the severe local type and moderate to severe diffuse type, sites treated with phenol showed repigmentation at 3 week, which was earlier than surgical deepithelialized sites. Therefore it is required to select appropriate method according to initial condition of pigmentation.

Purpose: This study aimed to identify prognostic factors for locoregional recurrence (LRR) in pT3N0 rectal cancer patients who were treated with surgery alone and had negative resection margin including circumferential resection margin (CRM) for optimal indication of adjuvant radiotherapy. Materials and Methods: We reviewed patients with pT3N0 rectal cancer who were treated via upfront surgery and had no other adjuvant treatment from January 2003 to December 2012. In total, 122 patients who had negative resection margin including negative CRM were included in the analysis. Results: The median follow-up period after surgery was 60 months (range, 3 to 161 months). During this time, 6 patients (4.9%) experienced LRR at the anastomotic site (4 patients), and regional lymphatic area (2 patients). The estimated 5-year rates of overall survival, recurrence-free survival, and LRR-free survival were 96.7%, 84.6%, and 94.0%, respectively. Multivariate analysis showed that level of tumor ≤5 cm was a significant prognostic factor for LRR-free survival (LRRFS) (p = 0.04; hazard ratio = 7.08; 95% confidence interval, 1.06-47.30). Patients with level of tumor ≤5 cm had an estimated 5-year LRRFS of 66.8%, which was much higher than 2.3% in patients with level of tumor >5 cm. There was no significant factor for recurrence-free survival or overall survival. Conclusion: In T3N0 rectal cancer, adjuvant chemoradiotherapy should be recommended in patients with level of tumor ≤5 cm for better local control. However, in patients with pT3N0 disease, negative resection margin, and level of tumor >5 cm, adjuvant chemoradiotherapy should be carefully suggested.

Purpose: Basal cell carcinoma is one of the most common cancers in the western population and the annual incidence rate is still on an increasing course. In Asian countries such as Korea, the incidence of basal cell carcinoma is reported to be remarkably low but is estimated to be in a steep increase nowadays. This study was to analyze the recent clinical trends of basal cell carcinoma in Korea by reviewing a single institution's experience. Methods: Throughout an 11-year period, the surgical excision of 143 cases of basal cell carcinoma was performed in our department. General data of these cases such as the primary site of cancer, age and sex of the patient, operative methods, recurrence rate were reviewed retrospectively. Results: Among the 143 patients included in this study, 82 patients were men and 61 patients were women. The ages ranged from 27 to 89 years with a mean age of 64.0 years. The head and neck region was the most frequently involved primary site for the cancer as 95.1% of the total cases occurred in this area. Especially the nose and perinasal area were the most frequent region, which was followed by the periorbital area, cheek, and perioral area. During this study period, 9 cases showed recurrence of the cancer as the overall recurrence rate was 6.3%. Conclusion: Gradual increase in the incidence of basal cell carcinoma was demonstrated in this study. Basal cell carcinoma showed high incidence in the old-age population as 68.5% of the total patients were more than 60 years of age. High recurrence rate was noted in the nasal region especially after local flap reconstruction. A more cautious approach is to be required when handing such high risk lesions. Multiple factors such as extended life span, increased outdoor leisure activity and exposure to sunlight, higher accessibility to medical services and increased understanding of the public about skin cancer are assumed to be the main reasons for this increase of basal cell carcinoma.

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.

Primary cutaneous mucinous carcinoma (PCMC) is a rare malignant tumor of eccrine origin. Clinically, the carcinoma presents as a solitary, slow growing, and painless nodule. For this reason, this tumor is often considered to be a benign mass in the preoperative setting. The lesion is, however, malignant in nature and has a tendency for local recurrence and infrequent metastasis. Wide local excision is the treatment of choice. However, few reports exist with information regarding surgical margins and clinical outcomes. Herein, we report a case of PCMC excised with a narrow surgical margin and review the relevant literature. A 49-year-old man presented with a small cutaneous nodule of the right cheek. The mass was excised without any margin, but pathologic examination revealed histology of mucinous carcinoma. Because of this, the operative site was re-excised with a 5-mm margin, and the wound was closed using a V-Y advancement flap. Systemic work-up did not reveal other potential metastatic primary, for a final diagnosis of PCMC. We report this case of PCMC, treated with relatively narrow margin in a patient with good prognostic factors.

Bone is a common site for metastatic spread from many kinds of malignancies. The morbidity associated with this metastatic spread can be significant, including severe pain. When it comes to spinal metastasis, occupying nearly 40% of skeletal metastases, the risks of complications, such as vertebral body collapse, nerve root impingement, or spinal cord compression, are also significant. Because of the necessity of preserving the integrity of the spinal column and the proximity of critical structures, surgical treatment has limitations when durable local control is desired. Radiotherapy, therefore, is often used as an adjunct treatment or as a sole treatment. A considerable limitation of standard radiotherapy is the reported recurrence rate or ineffective palliation of pain, either clinically or symptomatically. This may be due to limited radiation doses to tumor itself because of the proximity of critical structures. CyberKnife is an image-guided robotic radiosurgical system. The image guidance system includes a kilovoltage X-ray imaging source and amorphous silica detectors. The radiation delivery device is a mobile X-band linear accelerator (6 MV) mounted on a robotic arm. Highly conformal fields and hypofractionated radiotherapy schedules are increasingly being used as a means to achieve biologic dose escalation for body tumors. Therefore, we can give much higher doses to the targeted tumor volume with minimizing doses to the surrounding critical structures, resulting in more effective local control and less severe side effects, compared to conventional fractionated radiotherapy. A description of this technology and a review of clinical applications to bone metastases are detailed herein.
