Despite a sharp worldwide decline in the incidence and mortality due to gastric cancer during the second half of the 20th century, gastric cancer remains the world's second leading cause of cancer-related deaths. Variants of gastric cancer account for approximately 5% of all stomach carcinomas. Herein, we report on a rare case of combined germ cell tumor and adenocarcinoma that arose in the sto...

Primary bladder tumor is a frequent urological malignancy, whereas the incidence of secondary bladder tumor from a distant organ is quite rare. Secondary bladder neoplasms represent 1% of all malignant bladder tumors, of which distant metastases from stomach account for about 4% of cases. We present the case of a 30-year-old male who underwent partial gastrectomy for Signet-ring cell carcinoma ...

The synchronous occurrence of primary renal cell carcinoma with gastric cancer is very rare. We report a case of 41 year old male who presented on 05/07/2011 to M S Ramaiah hospital, Bangalore with history of fever, pain abdomen and malena. Ultrasound abdomen and pelvis showed large heterogenous mass arising from the upper pole of left kidney. Computed tomography of the abdomen showed left rena...

It is uncommon for gastric cancer to present clinically with symptoms attributable to distant metastases. This report describes 3 cases of carcinoma of the greater curvature and the posterior wall of the stomach that presented as metastases to the skin, bone, and lungs. In patients with adenocarcinoma of unknown origin, a gastric primary tumour, especially one along the greater curvature and po...

A composite carcinoma is a special tumor in which at least two different malignant cell types are blended. Such tumors have been documented in numerous gastrointestinal organs, but rarely occur in the stomach. Usually, they consist of an adenocarcinoma and neuroendocrine components (1-3). Here, we present a 64-year-old man with a gastric composite tumor including adenocarcinoma, neuroendocrine-...

A 74-year-old man suffered from jejunal perforation and adhesion to sigmoid colon due to adenocarcinoma associated with intraductal papillary mucinous neoplasm (IPMN) arising in a jejunal heterotopic pancreas. The jejunal lesion showed direct extension to the sigmoid colon, which was mistaken as sigmoid colon cancer by surgeons. Malignant transformation is a rare complication of a heterotopic p...

headings – Wistar Rats. Tumor markers, biological. Stomach neoplasms. abstRact Background: The N-methyl-N-nitrosourea (MNU) is a direct acting carcinogen, inducing tumors in several species in a variety of organs, including stomach of rats. Treatment of MNU in the drinking water for 25-42 weeks selectively induced glandular gastric carcinoma in F344 rats and C3H mice. Aim: To establish an exper...

The human UDP-glucuronosyltransferase (UGT) 1A (UGT1A) locus is regulated in a tissue specific fashion in liver and extrahepatic tissues. Three extrahepatic UGT1A proteins, UGT1A7, UGT1A8, and UGT1A10, have been discovered and are believed to contribute to the diversity of extrahepatic glucuronidation. UGTs eliminate by glucuronidation a broad variety of endobiotic and xenobiotic substrates, wh...

INTRODUCTION A case of carcinoma of the stomach presenting with cellulitis-like cutaneous metastasis is reported. CLINICAL PICTURE This patient was diagnosed to have early stage carcinoma of the prostate (T1bN0M0), which was treated with radiotherapy and hormonal therapy. He presented with an erythematous area of induration over the right neck a few weeks after the completion of radical radio...

INTRODUCTION Gastrocolic fistula is a rare complication of adenocarcinoma of the colon. Despite radical resections, these patients usually have a poor prognosis with a mean survival of 23 months and long-term survival is rarely reported. CASE PRESENTATION A 48-year-old Latino-American man presented with watery diarrhea, diffuse abdominal pain and weight loss for 3 months. A computed tomograph...
