A nosocomial pyogenic liver abscess caused by an extended-spectrum beta-lactamase-producing Klebsiella pneumoniae isolate presented in a man with adenocarcinoma of the stomach. The K. pneumoniae strain isolated from blood and liver aspirate cultures after antibiotic therapy for recurrent bacteremia was resistant to all extended-spectrum beta-lactams except imipenem and differed from K. pneumoni...

Signet cell carcinoma, which is a subtype of adenocarcinoma, usually originates from the stomach. However, it can also originate from the colon, rectum, gallbladder, pancreas, urinary bladder, and breast. We represent a 19-year-old boy diagnosed with signet cell tumour while he was being evaluated for an initial diagnosis of inflammatory bowel disease.

Primary signet ring cell adenocarcinoma is extremely rare. Signet ring cell carcinoma is more commonly primary in the stomach or breast, and the more likely metastatic disease to the cervix needs to be ruled out. We present a case of primary signet ring cell carcinoma of the cervix and review the literature.

Splenic metastasis is a rare clinical entity--incidence being 0.6% at autopsy and 1.1% at splenectomy. We report the case of a 30 year old female who presented with purpura and melena and who was later diagnosed to have a mucinous adenocarcinoma of stomach with disseminated intravascular coagulation and splenic metastasis.

Cutaneous metastasis from gastric adenocarcinoma is an infrequent disease entity. When present, it typically signifies disseminated disease with a poor prognosis. We report a case of a 57-year-old male patient with gastric cancer who developed generalized erythematous nodules on the chest, abdomen, back, neck, and four extremities 2 months postoperatively. Results of a skin biopsy disclosed gro...

We present a rare case of Peutz-Jeghers(P-J) syndrome in a 29-year-old woman who developed adenocarcinoma of the thyroid and polyps in the gastrointestinal tract. Polyps removed from the stomach, colon and ileum showed features typical of hamartomas. Histological examination indicated that the tumor resected from the right lobe of the thyroid was a papillary adenocarcinoma. This appears to be t...

Jejunal adenocarcinoma is rare, often presenting late with widespread intraperitoneal disease. Intraperitoneal chemotherapy (IPC) has been shown in non-randomized studies to improve the survival of patients presenting with intraperitoneal metastases from carcinoma of the colon, appendix and stomach and in primary peritoneal malignancies including mesothelioma and pseudomyxoma peritonei, providi...

According to the Brazilian health authorities, around 2,000 new cases of gastric cancer emerge in Brazil per year (Instituto Nacional de Câncer José Alencar Gomes da Silva, 2014). Indeed, gastric cancer constitutes the second most common cause of cancer-related mortality worldwide and 95% of such malignancies are adenocarcinomas (De Roover et al., 2006, and Clark et al., 2006). Roux-en-Y gastri...

Article history: Received 19 December 2016 Accepted 21 December 2016 Available online 23 December 2016 rarely detected early, and the prognosis remains poor (Pourhoseingholi et al., 2009) and recent study indicated association between MetS and increasing risk of gastric adenocarcinoma (Lin et al., 2015). The main finding of Hu and colleagues is an important issue, not only for clinicians who ar...

INTRODUCTION Most gastric tumors are adenocarcinomas. Primary gastric adenosquamous carcinoma is a rare malignancy, mostly associated with Asian populations. It constitutes less than one percent of all gastric carcinomas and its clinical presentation is the same as adenocarcinoma. It occurs more frequently in the proximal stomach, usually presents with muscular layer invasion and tends to be fo...
