A case is presented in which a gastric cancer primarily presented with symptoms of acute appendicitis. The difficulty of determining the origin of a carcinoma of the appendix with involvement of all layers of the wall is emphasized.

A woman, 32 years of age, was admitted with classical symptoms of acute appendicitis. Peroperative findings were typical of the condition. Histology revealed a colloid adenocarcinoma of colon-type, penetrating all layers. A secondary hemicolectomy was performed. One month previously the patient had undergone a conization of the uterine cervix on account of a cancer in situ. The age, sex, and the histological findings, altogether, make this case an extremely rare one. The literature has been perused, and it is concluded that hemicolectomy should still be considered the correct treatment for carcinoma of the appendix. The necessity of all specimens removed by surgery being sent for histological examination is emphasized.

Primary carcinoma of the appendix, though rare, occurs often enough to warrant its inclusion in diagnostic possibilities when the symptoms of acute appendicitis, without leukocytosis, are present in geriatric patients. A case of mucinous adenocarcinoma of the appendix in an 88-year-old white woman is presented. The substantial relief following right hemicolectomy has persisted for several months of follow-up.

The preoperative diagnosis of both appendiceal carcinoma and pseudomyxoma peritonei is difficult because of the nonspecific nature of the associated symptoms. More than 50% of all patients with carcinoma of the appendix are diagnosed with and treated for acute appendicitis. In addition, there have been few reports on patients with an appendiceal carcinoma or pseudomyxoma peritonei in association with other synchronous or metachronous malignancies of the alimentary tract. We herein report the first known patient with synchronous early gastric cancer and pseudomyxoma peritonei, in which the origin was correctly identified preoperatively.

An 19-year-old woman was admitted for acute appendicitis. The histological study of the appendix revealed a tubular variant of endocrine carcinoma of the appendix. Neuroendocrine tumors ("NETs") of the appendix are rare tumors which are usually detected incidentally, affecting 0.3% to 0.9% of appendectomies. Depending on their size, but also on some other factors, including histologic type, these tumors will require specific treatment; sometimes appendectomy will not be sufficient.

Non-carcinoid appendiceal malignancies are rare entities, representing less than 0.5% of all gastrointestinal malignancies. Because of their rarity and particular biological behavior, a substantial number of patients affected by these neoplasms do not receive appropriate surgical resection. In this report, we describe a rare case of primary signet-ring cell carcinoma of the appendix with peritoneal seeding which occurred in a 40-year old man admitted at the Emergency Surgery Department with the clinical suspicion of acute appendicitis. After a surgical debulking and right hemicolectomy, the patient had systemic chemotherapy according to FOLFOX protocol. After completion of the latter, the patient underwent cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy. This report offers a brief review of the literature and suggests an algorithm for the management of non-carcinoid appendiceal tumors with peritoneal dissemination.

Background: A goblet cell carcinoma of the appendix is a rare neoplasm with histological features of both adenocarcinomas and carcinoid tumours. It has a more aggressive behaviour in comparison to the more common classic neuroendocrine appendiceal tumours. Clinical presentation is variable and a significant proportion of patients present with an acute appendicitis. The aggressive evolution of these tumours makes the management more challenging.Case report: We report the case of a 43-year-old man with acute right iliac fossa pain who was initially diagnosed with an acute appendicitis. Histological analysis of the resected appendix demonstrated the presence of a goblet cell carcinoma with perineural and lymphovascular invasion. No distant metastasis was present. A right hemicolectomy was performed and adjuvant chemotherapy was administered.Conclusion: Goblet cell carcinomas is a distinct entity which should be delineated from the classical appendiceal carcinoids. Its clinical evolution obliges a more aggressive therapeutic strategy.
