malignant melanoma of the esophagus is a rare tumor with poor prognosis. the survival of patients is generally less than one year after diagnosis. a case of primary malignant melanoma of the esophagus is presented, who after radical resection of the tumor, is in excellent health, with no evidence of disease 14 months after surgery.

background : tongue cancer is one of the most common cancers of the oral cavity, excluding lip, and the median age of the patients is approximately 60 years. methods : treatment results of a total of 110 patients with oral tongue cancer admitted to cancer institute of tehran university between1999-2003 were retrospectively analyzed. the patients were treated by surgery or radiotherapy or chemot...

Esophageal involvement occurs in about 80% of patients with systemic sclerosis, with a marked diminution of peristaltic pressures in the distal two-thirds of the esophagus. Our aims were to more fully characterize esophageal motility disorders in systemic sclerosis using high-resolution manometry (HRM) and to determine predictive factors of esophageal involvement. Fifty-one patients (46 females...

Myocardial blood flow occurs during the diastolic phase of the cardiac cycle, because myocardial contraction during the systolic phase impedes myocardial perfusion. Using laser Doppler perfusion technique, we studied the effect of esophageal contraction on the esophageal wall perfusion. Studies were conducted in rats. A laser Doppler probe was anchored to the esophageal wall, and wall perfusion...

esophageal cancer is a lethal disease with poor survival rate. it is necessary to determine the extension, and the stage of the tumor to predict the outcome of patients. of the two common pathologic types, squamous cell carcinoma is still the most common form, and adenocarcinoma is the leading one. early diagnosis and radical treatment of esophageal cancer, regardless of tumor spreading, increa...

Background: Iran is located in Asian esophageal cancer belt, with age-standardized incidence rate (ASR) of approximately 7 per 100,000 for both men and women. To provide potential solution recommendations for achieving accurate estimations regarding the burden of the disease in Iran, we designed a study to assess the burden of esophageal cancer in Iran during 1995-2015 by collecting data from t...

Background: Manometry is the gold-standard diagnostic test for motility disorders in the esophagus. The development of high-resolution manometry catheters and software displays of manometry recordings in color-coded pressure plots have changed the diagnostic assessment of esophageal disease. The diagnostic value of particular esophageal clinical symptoms among patients suspected of esophageal m...
