1/9. Esophageal cancer: an unusual endoscopic appearance and presentation.

    Esophageal cancer in advanced stages grows to occlude the esophageal lumen; presenting symptoms include dysphagia and weight loss. Esophageal cancer rarely grows to occupy a narrow column of the esophagus or manifests neurologic symptoms. We report the case of a 58-year-old man with a history of tobacco and alcohol abuse and chronic obstructive airway disease who presented with headaches, left-sided weakness, unsteady gait, and weight loss. physical examination showed left-sided weakness. Computed tomographic scan of the brain and chest revealed, respectively, a right frontoparietal mass and a tumor mass in the distal esophagus. The patient's weakness and headaches improved after treatment with dexamethasone and craniotomy with partial enucleation of the brain lesion. An esophagogastroduodenoscopy revealed a large, elongated mass in the esophagus. Pathologic analyses of biopsies of the esophageal mass showed mixed adenosquamous carcinoma. The brain mass histology showed poorly differentiated carcinoma. Several weeks after craniotomy, the patient developed respiratory failure and died. While it appears that the esophageal cancer metastasized to the brain, there is the possibility of other undetected primary tumor with metastasis to the brain. Nonetheless, the endoscopic appearance and clinical presentation of this case are unusual and noteworthy.

2/9. Synchronous primary adenocarcinoma and adenosquamous carcinoma of the esophagus.

    Multiple malignant esophageal tumors of the same cell type are described. In the esophageal mucosa, widespread carcinomatous transformation may be observed and multicentric invasive squamous cell carcinomas may develop. The concomitance of two independent esophageal malignant neoplasms of different epithelial histogenesis is uncommon. Synchronous adenocarcinoma and squamous cell carcinoma of the esophagus is reported. Adenosquamous carcinoma of the esophagus is a rare tumor. adenocarcinoma of the esophagus represents 10% of esophageal cancer. We report a case of a synchronous primary invasive adenosquamous carcinoma and adenocarcinoma of the esophagus. Both tumors were demonstrated radiographically. The peculiarity of this neoplastic association and the importance of complete radiographic esophageal evaluation in patients with one obvious obstructing tumor of the esophagus are emphasized.

3/9. Molecular evidence for the same clonal origin of both components of an adenosquamous Barrett carcinoma.

    We describe an uncommon case of adenosquamous carcinoma arising in a barrett esophagus in a 72-year-old white man who occasionally used alcohol, and was a nonsmoker for 34 years. polymerase chain reaction-based microsatellite analysis was performed on the adenocarcinoma component (AC) and squamous cell carcinoma component (SC) of the tumor. The metaplastic Barrett epithelium (BE), the AC and the SC all showed loss of the same allele at 4 markers on chromosome 9p. Furthermore, the AC and the SC both showed loss of the same allele at all informative markers tested on chromosomal arms 3p, 5q, 10q, 14q, and 18q. In addition, both the SC and AC component contained the same missense mutation in the p53 tumor-suppressor gene. The only observed difference was a shift at a marker on chromosome 16q in the AC, whereas no shift was found in the BE and the SC. These findings suggest that this biphasic tumor has a monoclonal origin. The divergence presumably occurred late in the tumorigenesis of this carcinoma.

4/9. Adenosquamous carcinoma arising in Barrett's esophagus.

    Primary adenocarcinoma of the esophagus is rare in japan and, in most cases, arises from Barrett's esophagus epithelium. A 72-year-old man reporting heartburn and dysphagia and preoperatively diagnosed with adenosquamous carcinoma arising from Barrett's esophagus underwent thoracic esophagectomy and lymph node dissection in curative resection. Pathological diagnosis of the resected specimen showed adenosquamous carcinoma (coexistent adenocarcinoma and squamous cell carcinoma) invasive to the submucosal layer; metastasis was found in regional lymph nodes. Pathological staging was pT1bN1M0, stage II. Unfortunately, the man died of liver and lung metastasis 17 months postoperatively. To our knowledge, this rare case is only the fifth reported in the English literature on adenosquamous carcinoma arising from Barrett's esophagus.

5/9. Mucoepidermoid carcinoma (adenosquamous carcinoma) treated with Mohs micrographic surgery.

    BACKGROUND: Mucoepidermoid carcinoma (MEC), sometimes referred to as adenosquamous carcinoma (ASC), is a common malignant tumor of the salivary glands that can also develop from the esophagus, lacrimal passages, lung, upper respiratory tract, pancreas, prostate and thyroid. Rarely, MEC will present primarily in the skin. CASE: We present a case of primary MEC of the lower eyelid treated successfully with Mohs micrographic surgery. RESULTS: Mohs micrographic surgery was performed because of the highly aggressive and unpredictable nature of this tumor. The tumor was completely excised using Mohs with negative margins achieved in three stages. The patient has been disease free for 3 years since the surgery. CONCLUSION: We offer Mohs as an option for treating MEC.

6/9. Alpha-fetoprotein-producing esophageal carcinoma: a case report.

    We report herein a rare case of esophageal carcinoma producing alpha-fetoprotein (AFP). A 69-year-old man presenting elevated AFP was admitted in order to investigate its origin, which several liver examinations done before admission had not revealed. At admission, his serum AFP was 76.9 ng/ml whereas other tumor markers were within normal range. As the patient complained of mild swallowing disturbance, gastrointestinal examinations were performed, and an esophageal carcinoma was found at the esophagogastric junction. The patient underwent subtotal esophagectomy and the esophagus was reconstructed by gastric tube. The postoperative course was uneventful and the serum AFP level normalized immediately after the operation. Histopathological examination demonstrated the tumor to be poorly-differentiated adenosquamous carcinoma, which contained scattered adenocarcinoma composed of clear cells positive to AFP by an immunohistochemical stain. The patient has been well for six months after the surgery without any sign of recurrence.

7/9. Surgical eradication of esophageal carcinoma in a patient with Klippel-Trenaunay syndrome.

    Klippel-Trenaunay syndrome (KTS) is a rare congenital vascular disease of unknown etiology, and its occurrence with malignant tumor is extremely rare. We herein report a case of KTS presenting chronic gastrointestinal bleeding and complicating with adenosquamous cell carcinoma (ASCC) of the esophagus. The therapeutic dilemma of managing ASCC of the esophagus in a patient who combined with the rare congenital syndrome posed a difficult and interesting clinical problem. However, ASCC is also a very rare histological tumor in the esophagus, and its relationship to KTS has never been reported. In this article, we reviewed all the reported malignancies related to KTS. The possible surgical risks and complications, as well as preoperative imaging investigation, are also discussed.

8/9. Squamous cell carcinoma of the oesophagus with mucin-secreting component (muco-epidermoid carcinoma and adenosquamous carcinoma): a clinicopathologic study and a review of literature.

    The clinicopathological features of 11 cases of primary oesophageal squamous cell carcinomas with mucin-secreting component (eight muco-epidermoid and three adenosquamous carcinomas) are presented. The incidence was 2.2% of all resected primary oesophageal tumors. The mean age was 64 years and the male to female ratio was 4.5:1. The mean diameter of these tumours was 4 cm. Twenty-seven per cent of these tumours were in the upper, 46% in the middle and 27% in the lower portion of the oesophagus. The age, sex and site distribution of these tumors were similar to those of squamous cell carcinomas. The medium survival of these patients was 15 months. The world literature concerning this rare entity was reviewed and compared with the findings of the present study. No major racial differences were noted. In addition, the classification of this group of tumours was also discussed.

9/9. Adenosquamous carcinoma in Barrett's esophagus presenting as pseudoachalasia.

    A case of pseudoachalasia resulting from adenosquamous carcinoma arising from the mucous epithelium of a Barrett's esophagus is presented. This case represents an unusual combination of Barrett's esophagus giving rise to an esophageal carcinoma with squamous as well as glandular features, rather than the usual adenocarcinoma and pseudoachalasia.
