Gastric Signet Ring Cell Carcinoma: A Comparative Analysis of Clinicopathologic Features.

Signet ring cell carcinoma (SRC) is a distinct histological subtype of gastric carcinoma. Our aim is to investigate differential characteristics between gastric SRC and other non SRC carcinomas (nSRC). It was a retrospective study including 183 patients diagnosed with gastric carcinoma over a period of 5 years at our pathology department. We performed statistical comparison of clinicopathological features between patients with SRC and those with nSRC. 127 patients (69.4%) had nSRC, 56 had SRC (30.6%), the mean age was 56.67 ± 14.03 years. Patients with SRC were younger than those with nSRC (mean age of 49.66 versus 59.76, P = 0.030). Patients with SRC tend to have more diffuse tumors in the stomach (P = 0.005), with flat macroscopic appearance (P = 0.001). Patients with SRC present more often with pT3 tumors (P < 0.001), lymph node metastasis (P = 0.024) and perineural invasion (P = 0.003). There were no significant differences between SRC and nSRC in gender, vascular invasion or distant metastasis (P > 0.05). The median survival time was 42.82 ± 1.70 months. Patients with nSRC live longer than those with SRC, but the difference was not significant (P = 0.28). SRC is a histological subtype of gastric carcinoma with distinctive clinicopathologic features. The clinical management of patients should take into account these particular features.

[Epiploic appendagitis: a rare cause of acute abdomen]. / Appendagite épiploïque: cause rare d'abdomen aigu.

Epiploic appendagitis is a rare cause of acute abdomen. It can mimic other inflammatory processes such as diverticulitis or appendicitis. Diagnosis is based on CT scan. Medical management is the approach of choice in the absence of complications.

[Internal hernia through the falciform ligament: a rare cause of intestinal obstruction]. / Hernie interne du ligament falciforme: une cause rare d'occlusion intestinale.

Internal hernias are a rare cause of acute intestinal obstruction. Hernias through the falciform ligament is uncommon. Diagnosis is often made intraoperatively. Abdominal CT scan, performed in an emergency situation, can enable preoperative diagnosis and guide the therapeutic approach. In this respect, we here report a case whose data were collected in the Department of Visceral Surgery at the University Hospital Hassan II in Fez. The study involved a 48-year old patient, with no particular previous history, admitted to the Emergency Department with occlusion evolving over 4 days. Abdominal x-ray without treatment objectified multiple hydroaeric levels in small bowel some of which projected towards the hepatic region as well as the presence of a flat intestinal loop in continuity with distended intestinal segment. Abdominal CT scan was not performed due to altered renal function. The patient then underwent emergency surgery after stabilization of his condition and the diagnosis of internal hernias through the falciform ligament was made intraoperatively. In adults, internal hernia through the falciform ligament is a rare cause of acute intestinal obstruction in our daily practice. The diagnosis is most often made intraoperatively. It is necessary to suspect it in young patients with no history of abdominal surgery or intraperitoneal infectious process and with hydroaeric levels in the right upper quadrant.
