1/291. Pedunculated esophageal leiomyosarcoma: a case report.

    We report a case of esophageal leiomyosarcoma that possibly arose from the muscularis mucosae, thereby showing a particularly unusual appearance. A large polypoid intraluminal lesion in the distal esophagus was found on an endoscopic examination of a 68-year-old man with a 3-month history of dysphagia. Although the histological examination of biopsy specimens clearly revealed leiomyosarcoma, the absence of an exophytic component on computed tomography (CT) scan caused us to suspect that the tumor was carcinosarcoma. The tumor was resected by a subtotal esophagectomy. Microscopic evaluation revealed no involvement in the layer of the muscularis propria and no component of carcinoma. Clinical features of the pedunculated esophageal leiomyosarcoma shown in this case and three additional cases previously reported in the literature are reviewed.

2/291. Double cancers of the lung and esophagus associated with a sarcoid-like reaction in their regional lymph nodes: report of a case.

    A case of double cancers of the lung and esophagus associated with a sarcoid-like reaction in their regional lymph nodes is reported. A 73-year-old man with hemosputum was found to have a mass in his right lower lung field on a chest X-ray. Based on a diagnosis of lung cancer, a right middle and lower lobectomy with a dissection of the lymph nodes was performed. Microscopically, a well developed granulomatous reaction was seen in the dissected mediastinal and hilar lymph nodes. Three years after the pulmonary resection, he was admitted to our hospital because of dysphagia. A diagnosis of lower esophageal cancer was made. A lower esophagectomy with a total gastrectomy was performed. A sarcoid-like reaction comprising epithelioid cells and giant cells was seen in the regional lymph nodes. No clinical findings indicative of systemic sarcoidosis were observed. This rare condition may therefore help to improve our overall understanding of the relationship between malignant neoplasms and sarcoid-like reactions in the regional lymph nodes.

3/291. Primary esophageal T cell lymphoma.

    A 60 year-old woman with primary esophageal T-cell lymphoma in clinical stage I(E)B is presented. Immunohistologic examination showed tumor cells to be positive for anti-LCA, anti-UCHL-1, anti-MT-1, anti-CD3 antibodies, and negative for anti-L26 antibody. Disappearance of dysphagia and improvement in esophageal findings were noted after 65 Gy of irradiation, and biopsy specimens from the esophagus revealed no malignancy. Primary esophageal lymphoma is extremely rare, and this T-cell lymphoma is only the fourth case reported in the literature.

4/291. radiation-induced esophageal carcinoma 30 years after mediastinal irradiation: case report and review of the literature.

    A 54-year-old man who had been irradiated in 1964 for cervical involvement by Hodgkin's disease was admitted in December 1994 to our clinic with strong complaints of dysphagia. The reason was a moderately differentiated squamous cell carcinoma of the proximal esophagus in the previously irradiated region. The patient had no risk factors (abuse of nicotine or alcohol) for the developement of esophageal carcinoma. A reirradiation was performed, but the disease progressed locally and two weeks after the beginning of the therapy the patient developed two tracheoesophagocutaneous fistulae. The radiation therapy was discontinued and the tumor stenosis was bridged by a tube closing the fistulae. A retrospective dose analysis to evaluate the applied doses will be performed. Furthermore, an overview of 66 cases of the literature with radiation-induced esophageal carcinoma analysed concerning applied dose and latent interval will be given. In conclusion the reported case fits the criteria for radiation-induced malignancies (Chudecki Br J Radiol 1972;45:303-4) known from literature: (1) a history of previous irradiation, (2) a cancer occurring within the irradiated area, (3) gross tissue damage due to an excessive dose of radiation, and (4) a long latent interval between irradiation and development of cancer. Esophageal carcinomas belong to the rare secondary malignancies after the therapeutic use of ionizing radiation. Nevertheless in patients with dysphagia they should be suspected as a differential diagnosis even many years after mediastinal irradiation. The treatment of these tumors is very difficult and is associated with a poor prognosis.

5/291. leiomyosarcoma of the esophagus in a patient with chagasic megaesophagus: case report and literature review.

    leiomyosarcoma constitutes approximately 0.5% of the malignant neoplasias of the esophagus and its association with megaesophagus has not been described. We report on a case of a woman with dysphagia that was slowly progressive from the age of 19 due to chagasic megaesophagus. The woman was subjected to cardiomyotomy at the age of 49. She presented a rapid worsening of the dysphagia due to leiomyosarcoma at the age of 61, and was subjected to subtotal esophagectomy with cervical esophagogastroplasty. She developed pulmonary and hepatic metastases 14 months after surgery and died six months later.

6/291. Case report: A case of lymphoepithelioma-like carcinoma of the oesophagus and review of the literature.

    A 78-year-old Japanese female was admitted to our hospital with dysphagia and weight loss. An oesophageal tumour was demonstrated radiologically and endoscopically, and was diagnosed as oesophageal cancer by biopsy. Histologically, the resected tumour showed poorly differentiated squamous cell carcinoma with prominent lymphoid stroma and was diagnosed as the so-called lymphoepithelioma-like carcinoma (LELC). Epstein-Barr virus in the tumour was negative by polymerase chain reaction and in situ hybridization. Oesophageal LELC is extremely rare. The cases in the literature, as well as the one reported here, presented with gross features of a submucosal tumour-like appearance. Although the differentiation of the tumour cells is often poor, prognosis seems to be better than for other types of oesophageal cancer. Oesophageal LELC has characteristic clinicopathological features and should be classified by criteria independent of other types of tumour.

7/291. Esophageal sarcomas: report of three cases.

    BACKGROUND/AIMS: Sarcomas of the esophagus, including carcinosarcoma, are rare neoplasms. methods: The clinical and pathologic characteristics of 3 patients with esophageal sarcomas are presented, including the only recorded esophageal carcinosarcoma and 2 patients with leiomyosarcoma. RESULTS: All 3 patients were males who presented with dysphagia or an abnormal shadow of the mediastinum on a plain chest X-ray. Two tumors were in the middle esophagus, and the remaining one was in the distal esophagus. On endoscopic examination, all three tumors were noted to be polypoid. These patients underwent surgical excision. One patient died 7 days following the operation, and the remaining 2 patients died of liver metastasis 10 and 22 months following the treatment. CONCLUSION: esophagectomy or esophagogastrectomy is a surgical choice. Even if metastases are present, a palliative resection can still be performed.

8/291. Upper aerodigestive tract liposarcoma: report on four cases and literature review.

    OBJECTIVE: To report on the clinical behavior, histopathology, treatment, and prognosis of laryngeal, hypopharyngeal, and cervical esophageal liposarcomas. STUDY DESIGN: Retrospective reviews of pathology files and hospital records at a tertiary care hospital and a retrospective search of the English-language literature. methods: Cases of upper aerodigestive tract (UADT) liposarcoma with adequate histopathologic documentation and clinical information were included for review. RESULTS: Four cases of UADT liposarcomas were identified. The literature review revealed 26 cases of laryngeal liposarcomas, 7 cases of hypopharyngeal liposarcomas, and 6 cases of esophageal liposarcomas: the mean age at presentation was 55.8 years, the male:female ratio was 5:1, and 60% of the patients presented with dysphagia. Eighty-six percent of tumors had low-grade histologic findings. The recurrence rate after primary resection was 50%. recurrence correlated with surgical procedure rather than with histologic subtype; 94.7% of recurrences happened after simple excision. Distant metastases occurred in three patients; two of them died of the disease. CONCLUSIONS: The literature supports that UADT liposarcomas are rare and usually of low-grade histologic type. The rate of metastatic disease and tumor-related mortality is low. However, high recurrence rates have been noted, particularly when less radical surgery is employed.

9/291. A case of pseudosarcoma associated with type 3 squamous cell carcinoma of the esophagus: report of a case.

    A case of a primary esophageal pseudosarcoma associated with an independent type 3 tumor is described herein. A 60-year-old male presented with dysphagia and chest discomfort. A clinical evaluation revealed a type 3 tumor in the middle of the esophagus, which was diagnosed after a biopsy to be squamous cell carcinoma (SCC). A subsequent gross examination of the subtotally removed esophagus revealed a polypoid tumor adjacent to the type 3 tumor. Histologically, the polypoid mass was composed of SCC and mesenchymal components without a transitional zone. The tumor was thus classified as a pseudosarcoma of the esophagus, and was unique in that this appeared to have developed independently from the SCC.

10/291. esophageal perforation and mediastinal abscess following placement of a covered self-expanding metallic stent and radiation therapy in a cancer patient.

    patients with advanced esophageal cancer may require intubation with a stent to relieve debilitating dysphagia. However, if these patients also undergo radiation therapy, they may incur esophageal injury, thus increasing the risk of perforation after placement of the stent. Herein we report the case of a 71-year-old man who received such combination therapy and died of severe sepsis 65 days after the stent was inserted. An autopsy revealed that the stent had perforated into the mediastinal pleura and that an abscess had developed around the perforation. We conclude that caution should be taken before combining radiation therapy with the use of a stent.
