HEADINGS Esophageal neoplasms. Neoplasms, squamous cell. Adenocarcinoma. Esophagectomy. ABSTRACT Background Medical literature has recorded a significant and progressive increase in the prevalence of esophageal adenocarcinoma in recent years, and this fact has epidemiological importance in the treatment, in the evolution and prognosis of patients. Aim A retrospective study of esophageal tumors ...

Background/Aims Endoscopic submucosal dissection (ESD) is currently considered the first-line treatment for eradication of superficial neoplasms esophagus in Eastern countries. However, West, particularly Latin America, experience with esophageal ESD still limited because high technical complexity required its execution. This study aimed to present results clinical application manage a American...

Granular cell tumors are rare soft tissue neoplasms, among which only 2% are malignant, arising from nervous tissue. Here we present a case of a large esophageal granular cell tumor with benign histopathological features which metastasized to the liver, but showing on positron emission tomography-computerized tomography standardized uptake value suggestive of a benign lesion.

BACKGROUND Endoscopic submucosal dissection (ESD) permits removal of esophageal epithelial neoplasms en bloc, but is associated with esophageal stenosis, particularly when ESD involves the entire circumference of the esophageal lumen. We examined the effectiveness of systemic steroid administration for control of postprocedural esophageal stricture after complete circular ESD. METHODS Seven p...

Kidney and esophageal tumors induced by alkylating N-nitroso compounds 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 first base of codon 204 and the second base of 213, leading to amino acid substitutions Glu----Lys and Arg----Gln, respectively. In contrast to human neoplasms, a considerable fraction ...

Owing to recent advances in diagnostic and surgical techniques for cancer, a patient diagnosed with two or more neoplasms is not rare. We report on the case of a 58-year-old male with multiple primary malignant neoplasms, who suffered from three histological types of malignant neoplasm in six organs, namely the glottis, renal pelvis, urinary bladder, oral floor, prostate, and esophagus in chron...

Esophageal lipoma is an uncommon benign tumor of the esophagus and accounts for only 0.4% of all benign neoplasms of the gastrointestinal system. The majority of these are located in the cervical part; only very few are located in the lower third of the esophagus. We discuss the case of a 37-year-old female who presented with dysphagia and an esophageal lipoma located in the lower third of the ...
