Benign esophageal

By | May 6, 2012

Rare benign tumor of the esophagus, of which about 70% are smooth muscle tumors, followed by cysts, polyps, papilloma, hemangioma, fibroma, lipoma, adenoma, etc. These are quite rare.
Esophageal leiomyoma arising in the esophagus of esophageal leiomyoma in the myometrium, showing expansive growth, more than a full capsule, may apply to the cavity or tube of submucosal growth, showed a dumbbell-shaped bulge or to both sides of the growth. Most tumors were spherical, oval; a small number of irregular, partakers leafy, multiple nodules, horseshoe-shaped and spiral ginger, and so on. Mostly single, small can be multiple. Tumor surface mucosa normal or flattened, and even disappearance of mucosal folds. Lesions more common in the middle of the next section, followed by the upper low.
X ray showed the majority of smooth edges, sharp round, oval or lobulated filling defect. Smooth filling defect in the boundary are sharp, clear boundaries with the normal esophagus, often has an acute angle between the two, but also was an obtuse angle. Positive view of the tumor in the upper and lower ends of the barium shadow often a circular shadow, the "ring sign." To the cavity due to sudden tumor, mucosal folds flattened or disappeared, and the lumen widened and become flat, and therefore the area around the shallow than barium to form a so-called "waterfall sign" or "daubing." Some patients showed widened mucosal folds, lighter, thinner and discontinuous shape, aggregation, or spiral wrapping and other mass Traveling to change. Most cases cavity widened esophageal lesions; small number of cases leaving the tumor surrounding the esophageal stenosis, finishing the edges of the stricture. Lumen in some cases the phenomenon of a shift. Barium through smoothly in most cases, a few cases have different degrees of obstruction; in some cases, between tumor and contralateral esophageal wall between the tumor itself or lobulated, barium flow was setbacks Running. Contralateral esophageal tumor and the surrounding soft, comfortable and tumor shrinkage Zhang wall stiffness is different. Esophageal cancer occurs in the anterior wall of the trachea can cause pressure shift change. Corresponding parts of the lesions often see soft tissue; tumor is large, can be prominent in the mediastinum, should be noted that with mediastinal tumors. Imaging of mediastinal tumors in the esophagus, causing changes in the esophagus of external pressure may be identification of smooth muscle tumors.
Esophageal benign tumor 2. esophageal hemangioma is rare. Cancer Hospital Medical School opened 28 years found only 2 cases. 1 case of esophageal lesions. Barium esophageal lumen to the right below the rear section of oppression shift. The left front has a oval soft tissue mass, the esophageal mucosal integrity. 1 case of other lesions in the middle, showing polypoid intraluminal filling defect. Surgery and pathology were esophageal cavernous hemangioma.
3. Esophageal lipoma is rare. Medical Oncology Hospital, 1 case of pathologically confirmed, the patient has swallowing difficulties in 2 years of history. See barium esophageal cervical esophageal lumen expansion, polypoid filling defect cavity, the upper and lower curved edge, edge finishing, near the mucosa and tidy; belching into the right pyriform time, but are then swallowed the esophagus . See smooth tumor surgery, pedicle. Pathologically proved lipoma.
Benign esophageal 4. Esophageal cyst cyst is a congenital esophageal intestinal malformation caused by cysts or esophageal mucosa epithelium, but also with respiratory epithelium. Occurred in the middle or lower esophagus. Mild clinical symptoms. X ray findings were round or oval filling defects, edge finishing, no mucosal damage. May have soft tissue mass near the shadow, and smooth muscle tumors or bronchogenic cyst similar.
