Duplication of the alimentary tract, especially of the esophagus, have been regarded as rare cong- enital anomalies. However, they are being reported with increasing frequency in the literature. In the . ,- past they have been described by a variety of names, such as "enteric cysts", "intestinal cysts", "giant diverticula", "`mediastinal cysts of foregut origin" "enterogenous cysts" and other descriptive terms. . Most authorities now agree that these anomalies are best described by the term "duplications of the alimentary tract. The duplications [of the alimentary tract] are spherical or tubular structures which poses a well developed smooth muscle layer and are lined with a mucous membrane from any part of the alimentary tract. They may occur at any place in the digestive tube from the tongue to the rectum and usually are intimately attached to some portion of the alimentary tube. We have experienced a duplication of the esophagus in 14 years old middle schoolboy. He complained dysphagia, eructation and substernal pain associated with intermittent high fever and chilliness, increasing in severity for recent three weeks. Routine chest X-ray film revealed nore markable abnormal finding but esophagogram. revealed marked narrowing of the esophagus throughout with a large blind pouch in lower half with fistulous communication at mid portion of the esophagus. On thoracotomy, a large infected blind pouch communicating with the lumen of normal esophagus proximally, Was extended from the level of 5th to 10th thoracic spine. The duplicated segment of the esophagus has a common muscular .wall and proximal communication with the adjacent esophagus. The infected, duplicated esophagus was segmentally resected, and esophagogastrostomy with pyloroplasty was done by displacing the stomach into the right thoracic cavity through midline laparotomy. His Postoperative course was uneventful and discharged without complication.

Among varieties of the mediastinal tumors, benign developmental cysts [Entergenous cysts] occur about 10% of them. From the primitive foregut, tracheobronchial tree and esophagus develop at 3 weeks of its embryonal age, and bronchogenic cyst arises from accessory or supernumerary lung bud. Usually it remains isolated with surrounding structures, and causes no specific symptoms. But few cases of bronchogenic cysts have fistulous communication with esophagus causing compressive symptoms. We report a case of unusual complicated case of bronchogenic cyst with review of literatures.

Bronchogenic cysts are a congenital cystic lesion which are usually found within the lung parenchyme or mediastinum. Two cases of bronchogenic cysts were presented and related literatures were reviewed. The first case of bronchogenic cyst was located in the wall of the esophagus. Preoperatively, this case was thought duplication cyst of esophagus, but postoperative microscopic examination showed the tumor was a bronchogenic cyst with respiratory epithelium. The second case had double cysts; one in the superior and posterior mediastinum, the other in the lung parenchyme. The cyst in the mediastinum was extirpated and the other cyst in the lung was removed by right upper lobectomy. Postoperative course were uneventful in both patients.

Bronchogenic cysts are anomalous cystic lesions of foregut and usually located in the lung or mediastinum. Generally intramuscular cysts of the esophagus are considered as enterogenous foregut malformations. We report a young adult with an intramural bronchogenic cyst causing dysphagia and heartburn. It was located in the muscular layer of the esophagus and was removed without any damage to the mucosa. Histopathologic findings revealed that it was a bronchogenic cyst.

Bronchogenic cysts, though known as a relatively common malformation of the mediastinum, were rarely discussed in Korean literatures. Since the surgical removal of asymptomatic lesions was adopted as the reasonable therapeutic principle, the incidence of bronchogenic cysts were found to be higher than previously expected. Two cases of bronchogenic cysts operated on in The Dept. of Thoracic Surgery, Korea University Woo Sok Hospital were reported and related literatures were reviewed. Case 1. 5 year old boy with chief complaints of bulging cystic mass on left supraclavicular region during straining or coughing since his age of 2 was admitted, and cystogram with Lipiodol revealed hen-egg sized mass in the left antero-superior mediastinum without any communication with bronchus or esophagus. Cyst was successfully removed under general anesthesia thru left supraclavicular incision, and pathological examination of the cyst revealed thin cystic wall lined with stratified columnar epithelium and it`s content was milky white mucoid fluid devoid of any bacterial growth. Case 2. 15 year old school girl has been noted slowly growing walnut-sized mass on anterolateral side of the neck for 4 months without any subjective symptom except cosmetic problem... Mass was aspirated to find milky white mucoid fluid in some loculation and yellowish turbid fluid in other part due to chronic infection. Cystic tumor was removed under local anesthesia, which was loculated in between the trachea and esophagus without any communication, and pathological diagnosis of the cyst was bronchogenic cyst with columnar epithelial cell lining with moderate chronic inflammatory cell infiltrations. Postoperative conditions of the two cases were all excellent with normal life.

Bronchogenic cysts are usually located in the pulmonary parenchyma or mediastinum. When they are located in the mediastinum, they are usually near the bronchus or esophagus, but they are rarely at an intramural location of the esophagus. It is very difficult to differentiate between bronchogenic cyst and esophageal cyst before the operation. We report here on a patient for whom the preoperative diagnosis was supposed to be an esophageal cyst. The esophageal cyst was excised through the longitudinal division of the esophageal muscular layer without injury of the mucosa after right thoracotomy. The pathologic report revealed intramural bronchogenic cyst. We report here of a case of bronchogenic cyst that was located in the muscle layer of the lower esophagus.

Esophageal duplication cysts are quite uncommon benign lesions of the esophagus that have previously been described as occurring only in the thoracic cavity. We experienced a rare case of completely intra-abdominal esophageal duplication cyst in a 10-year-old boy who has suffered from epigastric abdominal pain. Surgical excision is recommended at the time of cyst discovery whether symptoms present or not.

This is to report a case of bronchgenic cyst. While most of the bronchogenic cysts reported in the literature so far were located either in the lung parechym or in the mediastinum near the tracheal bifurcation or main bronchi. the cyst presenting in this study was originated in the wall of the esophagus and was reported to be very rare. The cystic tumor was found accidentally by X-ray fluoroscopic examination of the esophagus and stomach in the patient with gastric hemorrhage. X-ray study revealed that the cystic tumor was oval in shape and located in the left posterolateral wall of the esophagus in the thoracic lower third. Two surgical operations, gastrectomy for gastric hemorrhage and the resection of the cystic tumor, were carried out separately. Gastrectomy including the removal of prepyloric ulcer by the Billroth II type procedure was performed in regular fashion, and the cystic tumor was resected radically without any injury of the mucous membrane of the esophagus. The cyst removed appeared to be filled with mucinous material, and histological examination identified the tumor as a bronchogenic cyst with ciliated epithelial internal lining. Postperative course of the patient was uneventful.

The esophageal cyst result from a wrong cleavage of the primitive gut in the 4 weeks embryo. In embryo and after seperation of the tracheal diverticulum, the esophagus is lined with ciliated cells which are able cover a "cystic duplication". It is often difficult to distinguish between the bronchogenic and the esophageal cyst. Pathological findings showed the presence of a ciliated epithelium without cartilage which was diagnosed as an esophageal cyst. The patient was 21 year old man for evaluation of the cyst in the posterior mediastinum. The cyst was located the intramural esophagus. Microscopically, the cyst was lined with ciliated columnar epithelium and there was no evidence of cartilage. The cyst was confirmed as the intramural esophageal cyst.geal cyst.

The prevalence of Sarcocystis spp. was investigated by gross and histopathological examinations in 250 camels (Camelus dromedarius) slaughtered from 2002 to 2005 in the Mashhad Slaughterhouse, eastern Iran. Samples were taken from the diaphragm, heart, tongue, esophagus and masseter muscles for histopathological studies. No macroscopic sarcocysts were found in the samples at gross inspection. Sarcocysts were detected in 209 of 250 (83.6%) examined camels at histopathological level. The infection rate of the esophagus, heart, masseter muscles, diaphragm, and tongue was 58.8%, 48.0%, 46.8%, 41.6%, and 28.0%, respectively. There was no significant difference in the rate of infection between male (85.8%) and female (81.0%) camels. The tissue response to vital cysts was minimal; however, reaction to the degenerating cysts was severe and caused tissue damages resulting in hyperemia, hemorrhages, mononuclear cell infiltration, necrotic changes, and fibrosis. The wild and domestic carnivores especially dogs may be the final hosts of Sarcocystis spp. in this area.
