stromal tumor that develops from gastro-intestinal (GI) mesenchymal cells from the esophagus to the rectum. Before 1990, most investigators thought these mesencgymal cell tumor to be the neoplasm from smooth muscle of gastrointestinal tract, and considered that these tumors were one kind of leiomyoma, leomyosarcoma or leiomyoblastoma. With the advent of immuno-chemical staining and ultra-struct...

Eccrine porocarcinoma is a rare neoplasm that originates from the intraepidermal ductal portion of the eccrine sweat gland, and it usually occurs on the pre-existing lesion of benign eccine poroma. Its occurrence is more common in females and elderly persons. We present a case of a 44-year-old man who suffered from eccrine porocarcinoma, which developed on the right scrotum and pelvic area with...

BACKGROUND Giant fibrovascular polyps (FVP) are relatively rare benign neoplasm of the upper esophagus and hypopharynx. Without previous history, their diagnosis might be difficult as the endoscopic findings are sometimes misinterpretedMaterials and methods: The present report describes a case, in which the patient regurgitated his giant polypoid mass into his mouth and captured it between his ...

Leiomyoma is a benign smooth muscle neoplasm. They can occur in any organ, but the most common forms occur in the uterus, small bowel and the esophagus. Leiomyoma of breast is a rare benign non epithelial tumor. Most leiomyomas in the breast are found in the subareolar region. There are few cases being reported in the literature. Here we report a case of 52 years old lady who presented to us wi...

The role of FDG-PET in oat cell carcinoma of the esophagus is hitherto unexplored. A MEDLINE search using the terms "small cell carcinoma" or "oat cell carcinoma" combined with "FDG-PET" yielded no report on this issue till date. We report, in this article, two cases depicting the usefulness of this modality in the management of this uncommon neoplasm. While reevaluation of unsuspected metastat...

Carcinosarcoma is an uncommon biphasic malignant neoplasm consisting of both carcinomatous and sarcomatous components. We report a case of an 84-year-old male with multiple carcinosarcomas occurring in the esophagus and stomach. Endoscopically, a bulky pedunculated polypoid lesion was observed in the middle of the esophagus and a huge discoid lesion in the lesser curvature. The patient received...

INTRODUCTION Primary malignant melanoma of the esophagus is a rare tumor representing only 0.1-0.2% of esophageal malignancies. The goal of the study was to report on the management of a new case diagnosed and treated in our site. CASE REPORT A 67-year-old patient presented with dysphagia to solids with no other remarkable history or associated skin lesions. He underwent gastroscopy, which re...

On a worldwide basis, cancer of esophagus is the sixth most common malignancy. In developing countries it ranks third in frequency and has one of the worst prognoses of any neoplasm of the human body. It is essential to detect the malignancy early and to determine the extent of the disease to ensure the best option for a cure. The aim of this study was to evaluate the frequency and pattern of O...

A 57-year-old woman was referred to the University of Michigan Hospital in July 1984 for evaluation of iron deficiency anemia. She was transfused with five units of blood and then underwent complete evaluation of her gastrointestinal tract. During double contrast examination of her upper gastrointestinal tract a 2.0 x 1.3 cm lobulated well demarcated polypoid lesion was found in the mid esophag...
