Purpose: We evaluated the effectiveness and safety of ipsilateral radiotherapy for the patient with well lateralized tonsil cancer: not cross midline and <1 cm of tumor invasion into the soft palate or base of tongue. Materials and Methods: From 2003 to 2011, twenty patients with well lateralized tonsil cancer underwent ipsilateral radiotherapy. Nineteen patients had T1-T2 tumors, and one patient had T3 tumor; twelve patients had N0-N2a disease and eight patients had N2b disease. Primary surgery followed by radiotherapy was performed in fourteen patients: four of these patients received chemotherapy. Four patients underwent induction chemotherapy followed by concurrent chemoradiotherapy (CCRT). The remaining two patients received induction chemotherapy followed by radiotherapy and definitive CCRT, respectively. No patient underwent radiotherapy alone. We analyzed the pattern of failure and complications. Results: The median follow-up time was 64 months (range, 11 to 106 months) for surviving patients. One patient had local failure at tumor bed. There was no regional failure in contralateral neck, even in N2b disease. At five-year, local progression-free survival, distant metastasis-free survival, and progression-free survival rates were 95%, 100%, and 95%, respectively. One patient with treatment failure died, and the five-year overall survival rate was 95%. Radiation Therapy Oncology Group grade 2 xerostomia was found in one patient at least 6 months after the completion of radiotherapy. Conclusion: Ipsilateral radiotherapy is a reasonable treatment option for well lateralized tonsil cancer. Low rate of chronic xerostomia can be expected by sparing contralateral major salivary glands.

Purpose: Chondroid syringoma is a rare mixed tumor of the skin that was first described by Hirsch and Helwig (1961). Characteristically, it is composed of the proliferation of epithelial cells in a myxoid and chondroid matrix. Most lesions occur on the head and neck region, and their size may range from 0.5~3 cm. Since a chondroid syringoma presents similar characteristics to other masses on the head and neck region, it is significantly important to distinguish with other masses by a surgical biopsy. Methods: A 51-year old woman presented with a painless nodular mass ($0.5{\times}0.5{\times}0.5cm$) on the philtrum, which appeared during the previous year. The mass was treated with a laser without a surgical biopsy. However, the size of the mass showed no changes. Surgical excision under local anesthesia was performed and sent for histopathology. Results: Gross examination showed a mass surrounded by a well developed capsule within the dermal layer. After complete excision without injury to the orbicularis oris muscle, the wound was covered with a local flap. The histology examination revealed numerous cuboid epithelial cells with tuboalveolar structures and keratinous cysts within a chondroid stroma. No recurrence or metastasis was observed at the follow-up visits. Conclusion: Chondroid syringoma is a rare mass on the face. An accurate diagnosis is essential for optimal treatment. This paper reports a case of a chondroid syringoma on the philtrum with a brief review of the relevant literature.

Background: Basal cell carcinoma (BCC) is the most common skin cancer. About 74% cases of basal cell cancer occur on the head and neck. Basal cell carcinoma on the face may have a higher degree of subclinical spread than tumors arising elsewhere. And incompletely excised BCCs become more aggressive when they recur. So the surgical removal and reconstruction of BCC located on the face are important to make perfect curing and cosmetic results. Methods: A retrospective study was done with 128 patients (137 cancers) who were treated with BCC on the face since 1987 to 2011. General data of these cases such as the primary site of cancer, age and sex of the patients, operative methods, and recurrence rate were reviewed. Results: The ratio of men to women was 1:1.4. And 86.9% of the patients with BCC were older than the age of 50 years with the mean age of 65.8 years. The distribution of facial basal cell carcinoma was on the nose, eyelids, cheek, and nasolabial fold. Surgical methods for treatment were local flap, full thickness skin graft, primary closure, and split thickness skin graft. Specifically, local flap consists of V-Y advancement flap, cheek advancement flap, limberg flap, forehead flap, nasolabial flap, rotation flap, transposition flap, bilobed flap, and island flap. Six cases recurred and all of them were treated with reoperation. Conclusion: The authors reviewed facial basal cell carcinoma cases in our hospital. This study might be helpful to choose appropriate operation method to manage BCC on face in Korea.

Purpose: Local recurrence is a common failure pattern in adenocarcinoma of the cecum. This study aimed to investigate the potential role of adjuvant radiation therapy on oncologic outcomes of patients with adenocarcinoma of the cecum. Materials and Methods: This retrospective study was carried out at three large tertiary university hospitals. We analyzed the characteristics, prognostic factors, and survival of 162 patients with adenocarcinoma of the cecum that were treated and followed up between 2000 and 2013. All the patients had undergone a right hemicolectomy and received chemotherapy with (n = 48) or without (n = 114) adjuvant radiation therapy. Results: The subjects were 65 females and 97 males with a median age of 56 years (range, 17 to 90 years) at diagnosis. The 5-year local control (LC), disease free survival (DFS), and overall survival (OS) rates were 72.7%, 57.2%, and 62.6% respectively. In a multivariate analysis, age, tumor stage, node stage, and adjuvant radiation therapy were determined to be independent prognostic factors. Age more than 55 years (hazard ratio [HR] = 1.0; 95% confidence interval [CI], 0.06-0.32; p = 0.003), T4 stage (HR = 6.8; 95% CI, 3.07-15.36; p < 0.001), node positive disease (HR = 4.2; 95% CI, 1.94-9.13; p < 0.001), and the absence of adjuvant radiation therapy (HR = 3.0; 95% CI, 1.39-6.46; p = 0.005) had a negative influence on OS. Conclusion: Adjuvant radiation therapy significantly improves DFS and OS in patients with adenocarcinoma of the cecum.

A 59-year-old male patient had 5-month history of gait disturbance and memory impairment. His initial brain computed tomography scan showed $3.5{\times}2.8cm$ sized mass with high density in the pineal region. The tumor was hypointense on T2 weighted magnetic resonance images and hyperintense on T1 weighted magnetic resonance images with heterogenous enhancement of central portion. The tumor was totally removed via the occipital transtentorial approach. Black mass was observed in the operation field, and after surgery, histopathological examination confirmed the diagnosis of malignant melanoma. Whole spine magnetic resonance images and whole body 18-fluoro-deoxyglucose positron emission tomography could not demonstrate the primary site of this melanoma. Scrupulous physical examination of his skin and mucosa was done and dark pigmented lesion on his left leg was found, but additional studies including magnetic resonance images and skin biopsy showed negative finding. As a result, final diagnosis of primary pineal malignant melanoma was made. He underwent treatment with the whole brain radiotherapy and extended local boost irradiation without chemotherapy. His preoperative symptoms were disappeared, and no other specific neurological deficits were founded. His follow-up image studies showed no recurrence or distant metastasis until 26 weeks after surgery. Primary pineal malignant melanomas are extremely rare intracranial tumors, and only 17 cases have been reported since 1899. The most recent case report showed favorable outcome by subtotal tumor resection followed by whole brain and extended local irradiation without chemotherapy. Our case is another result to prove that total tumor resection with radiotherapy can be the current optimal treatment for primary malignant melanoma in the pineal region.

Purpose: There are many methods for the reconstruction of the facial defect after an excision of a skin cancer; such as skin graft, local flap, free flap, etc... Skin graft has its' limitations; it could remain in different color with in regards of the recipient to donor, with an unfavorable scar. Free flap can lead to big donor site morbidity with long operation time and uncontrolled scar as a disadvantage factor. Compared to the prior, local flap offers several merits; sufficient blood supply, good tissue quality and short operation time. We revised 'V-Y-S flap' for the facial defect, which proved to have favorable outcomes. Methods: Total 7 V-Y-S flaps were performed to patients with skin cancers(six squamous cell carcinoma and one basal cell carcinoma). Two of these flaps were combined with composite grafts, one with full thickness skin graft. Six patients were female and one male. The average diameter of defects after excision was 2.3 cm. The follow-up period was 18 months maximally. Results: We treated seven facial skin cancers with 'V-Y-S flap'. There were no flap necrosis, cancer recurrence and scar contracture as a result. Furthermore, this method also offers a favorable central scar line that is parallel to the nasolabial fold and the nasojugal groove, especially in the nasolabial area and superomedial side of the cheek. With this method, we could cover a maximum diameter of 4cm facial defect. Conclusion: In conclusion, it is suggested that V-Y-S flap is a useful method to cover facial defects after the excision of a skin cancer.

Background and Objectives : The treatment of supraglottic stenosis remains a challenging problem in the field of otolaryngology due to its association with dyspnea, dysphagia, and frequent recurrence. Any satisfactory treatment is not yet known. The author experienced six cases of supraglottic stenosis and report the successful treatment of five cases by repeated endoscopic laryngeal excision with KTP-532 laser under suspension layngoscopy. Materials and Methods : Six adults who were treated for supraglottic stenosis between March 1994 and December 1998 at the Department of Otoloaryngology-Head and Neck Surgery, Korea University Medical Center were studied retrospectively. The patients were placed under general anesthesia followed by endoscopic laryngeal excision with KTP-532 laser under supension laryngoscopy. The scar tissue and granulation tissue were visualized with an operating microscope, and then removed using KTP-532 laser (15watts, continuous mode). Intraoperative local steroid(Triamcinolone ) was injected in all cases after the stenotic portions were removed. Results : Endoscopic excision was performed in five cases ; among the five cases, cricoid cartilage was concomitantly removed in two cases, and epiglottis was removed in one case. Satisfactory swallowing and airway respiration were possible in all five patients who underwent endoscopic widening. Conclusion : The treatment of supraglottic stenosis is different from that of tracheal or glottic stenosis in that supraglottic stenosis is mainly developed in membraneous form. Repeated laser excision and local steroid injection under suspension laryngoscopy is an effective and recommend able method for the treatment of supraglottic stenosis.

비강 및 부비동의 점막에서 발생하는 양성상피종양인 반전성 유두종은 비교적 드물며 1854년 Ward에 의해 처음으로 기술된 이래 여러 학자들에 의해 본증이 논의되어 왔으나 한국에서는 그 보고례가 매우 드물었다. 병리조직학적으로 양성인 이 종양은 비강이나 골 및 주위조직의 파괴성 병변이 빈번하고 수술 후 재발이 잘되고 드물게 악성으로 변하는 성질을 나타내므로 임상적으로 악성으로 알려져 왔다. 일단 반전성 유두종으로 확진되게 되면 가능한 한 광범위한 절제가 필요하며 술 후에도 계속적이 추적조사가 필요하다고 하겠다. 최근 저자들은 비폐색, 종류감을 주소로하여 내원한 48세된 남자환자에서 우측비강, 상악동에서 발생하여 국소적으로 악성화 변화를 일으킨 반전성 유두종 1례를 비내 및 Caldwell＿LUC식 방법으로 절제후 Bleomycin 정맥주사, 5＿FU 국소분무요법 및 방사선요법($Co^{60}$)을 병용하여 좋은 결과를 얻었기에 이를 문헌적 고찰과 함께 보고하는 바이다.
