Esophageal carcinosarcoma is a rare malignant neoplasm consisting of both carcinomatous and sarcomatous components. It is generally treated by surgery, radiotherapy and chemotherapy according to the protocols used for other esophageal cancers. However, the treatment of esophageal carcinosarcoma by radiotherapy alone before surgery has not been previously described. We report a patient with a ra...

Sarcomas of the esophagus, including carcinosarcoma, are rare neoplasm cases and comprise 0.1-1.5% of all esophageal tumors. Leiomyosarcoma is the most common of the pure mesenchymal tumors of the esophagus, but sarcomas with combined histological types such as carcinosarcoma occur more frequently than pure sarcomas. We report a rare case of spindle cell sarcoma of esophagus in a 55-year-old wo...

introduction primary malignant esophageal melanoma makes up 0.1% to 0.2% of all esophageal malignancies. most physicians assume malignant melanoma as a skin originated neoplasm, however this type of melanoma can occur anywhere in the gastrointestinal tract especially in the esophagus. thus, it is essential to consider malignant melanoma in differential diagnosis of any esophagus masses. case pr...

Intestinal adenocarcinoma is an invasive malignant neoplasm that originates from glandular tissue, with metastatic potential. The best treatment surgical correction, and the anesthetic protocol chosen directly related to successfulness of procedure. This study aims report approach in a feline intestinal submitted resection anastomosis. An 11-year-old mixed breed was examined diagnosed neoplasia...

A 53-year-old man was suspected of having an esophageal neoplasm. An endoscopic examination including Lugol chromoendoscopy suggested an esophageal squamous cell neoplasm limited to the lamina propria. A targeted biopsy showed atypical squamous cells, and an endoscopic submucosal dissection was performed 22 days after the previous endoscopy. Although a single 40 mm unstained area was observed b...

Although gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal tract, it rarely arises from the esophagus and is thus very rarely the cause of a mediastinal mass. We report a case of esophageal GIST presenting as a mediastinal mass in a 59-yearold male. If such a tumor has extremely exophytic growth, it may result in a huge mediastinal mass withou...
