식도의 양성 종양은 흔하지 않았으며 이중 신경초종은 아주 드문 식도 양성종양이다. 봉원에서는 점점 심해지는 연하곤란을 주소로 내워한 52세 여자환자에서 식도에 생긴 신경초종을 우측 개흉술을 통한 종양 적출술로 성공적으로 제거 하였기에 이에 문헌 고찰과 더불어 증례 보고하는 바이다.

Though leiomyoma is the most common tumor of esophagus, it accounts for only 1% of all esophageal tumors. Most of the leiomyomas are intramural type originating from the muscularis propria and only l% of them is intraluminal pedunculated type originating from muscularis mucosae. Recently, a 30-year-old male was admitted to our hospital because of dysphagia. Radiologic examination showed that intraluminal tumor 5cm in diameter was found at the cervical esophagus. Endoscopic examination showed that the tumor was covered with normal mucosa. The patient underwent surgical excision through the left cervical approach. After full, longitudinal esophagotomy, the intraluminal pedunculated tumor was successfully enucleated. Esophageal leiomyoma was confirmed histopathologically. Postoperative course was uneventful and the patient was relieved from dysphagia.

양성 신경초종(benign schwannoma)이 식도를 포함한 위장관계에 발생하는 경우는 매우 드물다. 이러한 양성식도 신경초종은 확진을 위해 면역 조직 화학적 염색을 필요로 한다. 정기 신체 검진상 우연히 발견된 66세여자 환자의 식도 점막하 종양에 대해 우측 후측부 개흉을 통한 종양 적출을 시행하였으며, 술후 면역 조직 화학적 병리 검사를 통하여 식도의 양성 신경초종임을 확인하였고, 환자는 술후 1년째 재발없이 외래 추적 관찰을 받고 있다.

Gastrointestinal stromal tumors (GISTS) are rare, but potentially aggressive tumors. GISTS are generally found in the stomach or small intestine and less commonly in the colon, rectum, or an intra-abdominal sites but have rarely been documented in the esophagus. GISTS were definded as the most common mesenchymal tumors of the gastrointestinal tract for which there is incomplete understanding of their lineage, while their relationship with differenciated. We reported a very rare case of GISTS of lower esophagus in a 60-year-old woman with relevant literature review.

The coexistence of mesenchymal tumor and carcinoma in the esophagus is extremely rare. We report a case of squamous cell carcinoma located at the mucosal surface over leiomyoma of the esophagus. A 76-year-old man with complaints of 3 months onset of odynophagia was diagnosed preoperatively as squamous cell carcinoma over submucosal tumor with calcification. Esophagectomy and esophagogastrostomy were performed through the right thoracotomy and upper median laparotomy. The patient is doing well without evidence of recurrence in the 25 months after resection. We discuss the pathogenesis and possible relations between the two tumors.

A rare case of schwannoma involving lower thoracic esophagus is presented. A 64-year-old male was seen with slowly progressing dysphagia for 2 years. Large sized submucosal tumor was found by endoscopy and chest CT. On surgery, tumor was very solid and tightly adherent to the adjacent tissue. Esophagectomy and esophagogastrostomy was done.

Primary malignant melanoma of the esophagus(PMME) is an uncommon neoplasm. And the world literature reports only about 200 cases. A case of primary malignant melanoma of the esophagus is presented, and followed by review of the literature. In our patient, the walnut-sized melanoma was located at the midportion of esophagus and there were two small satellite lesions at the esophagogastric junction. The main mass was diagnosed as primary malignant melanoma histologically and immunohistologically. The tumor was curatively resected by the transthoracic subtotal esophagectomy and the 2 fields node dissection. Post- operative immunotherapy was performed but the tumor recurred 7 months later at the stomach.

Esophageal schwannoma is very rare and almost of all cases are diagnosed as esophageal submucosal tumor preoperatively. Final diagnosis is made by postoperative immunohistochemical (IHC) staining of the surgical specimen. We experienced two cases of esophageal submucosal tumor, one was 63 year old female suffering from three months of dysphagia and another was 39 year old female complaining of two months of intermittent dysphagia. Two esophageal tumors were completely removed by esophagectomy and enucleation through right thoracotomy respectively. Postoperative IHC staining demonstrated S-100 positive without mitotic figures and confirmative diagnosed was made as benign esopphageal schwannoma.

Herein we report a rare case of primary esophageal malignant melanoma in a 56-year-old gentleman who presented with a 2-month dysphagea. Esophagoscopy reveals a polypoid tumor and a total thoracic esophagectomy was performed through a right thoracotomy and esophageal replacement with stomach. The tumor was proven to be a primary esophageal malignant melanoma by histological and immunohistochemical studies. The pathologic stage was IIa. He received no postoperative adjuvant therapy. He died of liver metastasis at 8 months postoperatively.

Gastrointestinal stromal tumor is documented on every part of the gastrointestinal tract. It develops in the stomach and the small intestine most commonly, and also in the esophagus. A 44 year-old male patient was admitted due to dysphagia and weight loss. Chest CT showed about $15\times11\times11cm$ sized, well-defined, and lobulated soft tissue mass with central necrosis was noted in the posterior wall of lower esophagus throughout the lesser curvature of upper stomach. We performed the distal esophagectomy and total gastrectomy using thoracoabdominal incision. The tumor was positive at CD117 (c-kit) and CD 34, and was diagnosed as malignant GIST of the distal esophagus and upper stomach. The patient is on routine follow up at the out patient department for nineteen months up to now.
