The authors describe a case of acute appendicitis associated "serrated" adenoma (SA). to the histological finding of a SA is a colorectal pre-cancerous lesion which presents the morphological and architectural characteristics of hyperplasic polyps, combined with aspects of adenomatous dysplasia. SA can eventually evolve into a malignant cancer, similarly to classic adenomatous polyps. Clinical and pathological aspects of this lesion are hereby analysed, with respect to recent Literature data.

An ectopic ureter draining into the seminal vesicle or vas deferens in males is a very rare anomaly and is usually associated with renal dysplasia or agenesis. An ectopic ureter associated with a dysplastic kidney is not usually a suspected cause during clinical evaluation of children with abdominal pain. This report presents a rare case of an ectopic ureter associated with a dysplastic kidney with an acute infection in a previously healthy 12-year-old boy, demonstrated by magnetic resonance imaging. He presented with abdominal pain that mimicked acute appendicitis-like symptoms which was subsequently complicated by epididymitis manifesting as an acute scrotum. Clinicians should consider including an ectopic ureter in the differential diagnosis of children presenting with acute abdomen.

Goblet cell carcinoid tumor of the appendix is an uncommon neoplasia that shares the histological attributes of both adenocarcinoma and carcinoid tumors. Its prognosis has a more aggressive course than the other known carcinoid tumors. Clinical diagnosis of goblet cell carcinoid is seldom made preoperatively. The most common clinical presentation of goblet cell carcinoid tumor is acute appendicitis. In this study, we report a patient on whom right hemicolectomy was performed because of a cacal sessile polyp with high grade dysplasia; goblet cell carcinoid tumor of the appendix was revealed incidentally during microscopic evaluation of the appendectomy specimen. The patient healed uneventfully and no recurrence was observed after the 12-month follow-up period. Careful microscopic examination of the appendectomy specimen is key for the diagnosis of appendiceal tumors such as goblet cell carcinoid, especially in elderly patients.
