Muir-Torre syndrome is defined by concurrent or sequential development of internal malignancy and sebaceous neoplasm or multiple keratoacanthomas. Muir-Torre syndrome is very rare, with only 205 cases reported in the literature. We reported a patient with Muir-Torre syndrome with three internal malignancies. A 64-year-old patient with a history of breast cancer, stomach cancer and colon cancer visited our department for treatment of the skin lesion that occurred five years before on the left cheek. The lesion was excised completely with a resection margin of 1 cm, followed by full-thickness skin graft from left postauricular area for reconstruction. Histopathology revealed a $0.2{\times}0.2{\times}0.1cm$ sized sebaceous carcinoma with 4 mm safety margin. The skin graft was well taken within 7 days after surgery and the patient was discharged to outpatient follow-up. There was no complication related with surgery. Muir-Torre syndrome is very rare, as are sebaceous gland tumors. So if a cancer of the sebaceous gland is diagnosed, screening workup for internal malignancy is recommended. Because of its good prognosis, surgical removal of primary or metastatic cancers may be curative and should be attempted where possible.

Human sparganosis is a food-borne zoonosis mainly caused by the plerocercoid belonging to the genus Spirometra. The most common clinical sign of sparganosis is a subcutaneous mass in the trunk including abdominal or chest wall. The mass may be mistaken for a malignant tumor, thereby causing difficulty in terms of diagnosis and treatment. A 66-year-old woman visited our clinic for the removal of a lipoma-like mass. It was movable, hard, and painless. we identified 2 white mass, measuring $0.2{\times}4cm$ and $0.2{\times}1cm$. Pathologic finding indicated the white mass was a sparganum. She recalled having eaten a raw frog approximately 60 years before. A 35-year-old who lived North Korea was also presented to our clinic with an asymptomatic nodule on her abdomen. Intraoperatively, we found sparganum approximately 24 cm size. Subcutaneous masses are associated with clinical signs of inflammation or they may mimic a soft tissue neoplasm. While the incidence rate of sparganosis has decreased with economic development and advancements in sanitation, surgeons still encounter patients with sparganosis in the clinical setting. Therefore, a careful history is required in order to diagnose sparganosis.

Fibrofolliculoma is a benign tumor characterized by a smooth, dome-shaped papule of size 2-4 mm. Most fibrofolliculomas occur as multiple lesions, and very rarely, they are solitary. Herein, we report a case of solitary fibrofolliculoma found in the alar rim, without the typical characteristics of a fibrofolliculoma. A 42-year-old man visited the hospital with a protruding lesion that had occurred 1 year previously. A mass of size 5×7 mm was observed on the left alar rim. The tumor was dome-shaped and palpable. The patient did not have any similar lesions elsewhere. No family member was known to have such a lesion. An incisional biopsy was performed before surgery, and pathological examination revealed hyperkeratosis and dyskeratosis; however, an accurate diagnosis was not made. Complete resection was planned for the mass on the alar rim. The resected mass was subjected to permanent biopsy, and the pathological examination results led to the diagnosis of fibrofolliculoma. Therefore, when diagnosing a dome-shaped mass in the alar rim, despite the suspicion of a very rare disease, it is necessary to suspect fibrofolliculoma and consider the process from diagnostic examination to treatment.

Schwannomas, which originate from Schwann cells in the peripheral nervous system, are slowg-rowing and uncommon benign tumors. Most schwannomas (90%) occur in isolation, and multiple occurrences are a characteristic feature of neurofibromas. Schwannomas of the nose and nasal tip are particularly unusual. Although a few cases of schwannomas of the sinusoidal tract and nasal septum have been reported, schwannomas arising from the nasal dorsum area and tip are extremely rare. Sensory abnormalities are also a very rare symptom. We excised a schwannoma on the nasal dorsum through direct incision and a schwannoma on the nasal tip through open rhinoplasty. No postoperative complications involving recurrence, hematoma, or infection occurred. The possibility of neurological changes should be considered in cases of an abnormality in the peripheral nervous system. Schwannoma must be kept in mind as a possible cause of neurological changes localized to a specific dermatome, and should always be considered in the differential diagnosis of a mass on the nose.

Head and neck cutaneous metastasis of advanced gastric cancer is uncommon, and scalp metastasis is particularly rare. We present the case of a 60-year-old man who was diagnosed with cutaneous metastasis on the scalp originating from advanced gastric cancer. The patient was referred to the plastic surgery department for a scalp mass near the hairline. He had been diagnosed with advanced gastric cancer and undergone total gastrectomy and Roux esophagojejunostomy 3 years previously. The differential diagnosis for a single flesh-colored nodule on the scalp included benign tumors such as epidermal cyst or lipoma; therefore, the patient underwent excision and biopsy. In the operative field, the mass was found to be located in the frontalis muscle. The biopsy result showed that the mass was a metastatic lesion of advanced gastric cancer. Whole-body computed tomography revealed a gastric tumor with blood vessel infiltration, peritoneal carcinomatosis, liver metastasis, and multiple disseminated subcutaneous metastases. Although scalp metastasis originating from an internal organ is extremely rare, plastic surgeons should always consider a metastatic lesion in the differential diagnosis if a patient with a scalp lesion has a history of malignant cancer.

Fibrofolliculoma is a benign, perifollicular, connective tissue tumor that usually arises in the form of multiple lesions; it is rarely seen as a solitary lesion. The lesions are clinically asymptomatic, 2 to 4 mm skin-colored, soft dome-shaped papules. Here, we report a patient who visited our hospital with a palpable lesion on the nasal septum. The lesion did not cause pain upon palpation, and nasal endoscopy confirmed an irregular wart-like lesion measuring 6×6 mm in the left anterior nasal septum near the columella. Other otolaryngology findings were normal, and there were no similar lesions in other parts of the body. None of the patient's family members were known to have had such lesions. An excisional biopsy was performed on the mass for removal of the lesion, and histological examination confirmed the lesion as fibrofolliculoma. We report the first case of solitary fibrofolliculoma in the nasal septum in a healthy 62-year-old woman along with a review of the relevant literature.

Purpose: Parotid neoplasia are relatively frequent, representing approximately 3% of all tumors in the head and neck regions. But incomplete resection and misdiagnosis of parotid gland is followed by multiple tumor invasion, tumor recurrence, and other iatrogenic tumor formation. In patients undergoing parotidectomy for confirmed or suspected malignancy, the traditional or modified rhytidectomy incision may prove suboptimal because it does not easily lend itself to a continuous neck dissection. Similarly, patients with tumors of the anterior accessory lobe or patients with large anterior tumors may also require the modified Blair incision for adequate surgical exposure. This report serves to revisit the topic of accessory and parotid gland neoplasms to emphasize proper management, particularly the surgical aspects, so that consequences of recurrence are avoided. Methods: This is a retrospective review of our experience with two cases of parotid tumors; one accessory parotid gland neoplasm and one parotid gland neoplasm. We report the case of parotid tumor and epidermal cyst in a 54-year old male patient and the case of case of recurrent parotid tumor with local invasion in 30-year old male patient. Results: All were removed through a modified Blair incision. Pathologic report notified that One was found pleomorphic adenoma and epidermal cyst, and the other one pleomorphic adenoma with subcutenous invasion. The patients recovered well without any complication such as infection, hematoma, facial nerve palsy, and necrosis of skin flap. Patients were discharge POD#7. Patients were followed up to for 1 year and they have no sign of recurrence. Conclusions: A high index of suspicion, prudent diagnostic skills(including fine-needle aspiration biopsy, CT, US), and meticulous surgical approach are the keys to a successful management of these lesions. We experienced two cases of parotid neoplasia, in the treatment of tumor reccurence & iatrogenic tumor arising from the parotid gland and are presented with the review of literatures.

절제된 IIIA N2병기 비소세포형 폐암에 있어서 종격동임파절의 전이 양상에 따른 임상적 특성을 알아보고, 예후에 미치는 영향에 대해 평가해 보고자 하였다. 대상 및 방법: 1991년 1월부터 2000년 12월까지 비소세포형 폐암으로 폐엽절제술 이상의 수술을 받은 환자 중 수술 전 항암 화학요법 또는 방사선 치료를 받은 환자와 수술 사망 환자를 제외한 174명을 대상으로 후향적 연구를 자였다. 결과: 상엽 종양에서 하부 종격동임파절로 전이된 경우 5년 생존율은 32.3%로서,하부 종격동임파절 전이가 없는 환자의 5년 생존율 25.6%와 차이가 없었다(p＝0.86). 하엽 종양에서 상부 종격동임파절로 전이된 경우 5년 생존율은 25.1%로, 상부 종격동임파절 전이가 없는 환자의 5년 생존율 14.1％와 비교하여 통계학적인 차이가 없었다(p＝.33). 전체 환자 중 subcarinal node로의 전이에 따른 생존율의 비교시 전이 유무에 따른 5년 생존율에 차이가 없었다(20.9% vs 25.6%, p＝0.364). 전이된 종격동임파절의 station수에 따른 비교 시 single station군의 5년 생존율은 26.3%로, multiple station군의 18.3%보다 생존율이 유의하게 높았다(p＝0.048). Multiple station군에 있어서 수술 후 항암 화학 요법 및 방사선 치료를 병행한 경우 5년 생존율 34.2%로서 생존율의 향상이 있었다(p＝0.01). 수술 후 생존에 영향을 미치는 인자로는 연령 $\geq$60세(O.R: 1.682, p＝.006), multiple station N2 (O.R: 1.503, p＝.021), 전페절제술(O.R: 1.562, p＝.018), 수술 후 항암 화학요법 및 방사선 치료(O.R: 0.625, p＝.012)등이 있었다. 결론: 절제된 IIIA N2 병기 비소세포형 폐암에 있어서 전이된 종격동임파절 부위의 수(single vs multiple station)가 술 후 생존에 영향을 미치는 중요한 예후 인자였으며, multiple station N2의 경우 수술 후 항암 화학요법 및 방사선 치료를 병행함으로써 생존율을 높일 수 있으리라 생각된다.
