Rhabdomyomatous well-differentiated esophageal liposarcomas are extremely rare. As of August 2016, only one other such case has been reported in the English-language medical literature. Liposarcomas in general are one of the most common soft tissue neoplasms in adults, but the incidence of primary esophageal liposarcomas is exceptionally low. There have been only 42 reported cases of primary li...

Kidney and esophageal tumors induced by alkylating /V-nitroso com pounds in rats contain a high incidence (75-100%) of G -> A transition mutations in the p53 gene. These are almost selectively (89%) located in the tirsi base of codon 204 and the second base of 213, leading to amino acid substitutions Glu -»Lys and Arg -»Gin, respectively. In contrast to human neoplasms, a considerable fractio...

Endobronchial metastases from extrapulmonary neoplasms are rare events and there is no report on the metastasis originating from esophageal cancer. Basaloid squamous carcinoma of the esophagus is a rare histologic type, which is known as biologically aggressive phenotype. We describe a rare case of metachronous endotracheal metastasis originating from esophageal basaloid squamous carcinoma. A 7...

AIM To investigate post endoscopic submucosal dissection electrocoagulation syndrome (PEECS) of the esophagus. METHODS We analyzed 55 consecutive cases with esophageal endoscopic submucosal dissection for superficial esophageal squamous neoplasms at a tertiary referral hospital in South Korea. Esophageal PEECS was defined as "mild" meeting one of the following criteria without any obvious per...

Background and AimsDiagnosis of esophageal cancer or precursor lesions by endoscopic imaging depends on endoscopist expertise is inevitably subject to interobserver variability. Studies computer-aided diagnosis (CAD) using deep learning machine are the increase. However, studies with small sample sizes limited inadequate statistical strength. Here, we used a meta-analysis evaluate diagnostic te...

Primary malignant melanoma of the esophagus is a rare but aggressive tumor that accounts for <1% of all esophageal neoplasms.1 Worldwide, approximately only 250 cases have been published in the English literature to date,2 however, individual case reports have been described in the radiology literature.3,4 We report 2 male patients with histopathologically confirmed primary malignant melanomas ...

The Fifth edition of the World Health Organization classification digestive system and American Joint Committee on Cancer staging manual contain substantial refinements information for esophageal tumors. epithelial tumors esophagus are classified as benign, dysplasia, malignant groups. Dysplasia is divided into Barrett dysplasia squamous graded either low-grade or high-grade. Malignant often ad...

High preoperative serum midkine concentration is associated with poor survival in patients with esophageal cancer, even after radical surgery, and thus may have prognostic value. Midkine (MK), a heparin-binding growth factor, is expressed in numerous cancer tissues, and serum MK (S-MK) concentrations are increased in patients with various neoplasms. The aim of this study is to evaluate the clin...

Preinvasive lesions of squamous cell carcinoma are well defined morphologically and provide a model for multistage carcinogenesis. Since alterations in the p53 tumor suppressor gene occur frequently in invasive esophageal squamous cell carcinoma, we examined a set of preinvasive lesions to investigate the timing of p53 mutation. Surgically resected tissues from nine patients with esophageal squ...
