Meckel's diverticulum is a true diverticulum from remnant of vitelline duct. It is most common congenital anomaly of intestine. It is associated with intestinal atresia and anorectal anomalies. It contains heterotrophic epithelium. Most common heterotrophic mucosa is gastric followed by pancreatic tissue. Adenocarcinoma arising from Meckel's diverticulum is very rare. Spontaneous perforation of adenocarcinoma rarely reported. Most of perforation reported in Meckel's diverticulum diagnosed during intraoperative period. This is a case report of spontaneous rupture of adenocarcinoma of Meckel's diverticulum, which was managed with primary resection and ileostomy.

Adenocarcinoma ex-goblet cell carcinoid is a very rare and histologically unique appendiceal malignancy with dual glandular and neuroendocrine differentiation. There is a high incidence of this tumor among middle-aged women with metastasis to the gynecologic tract with the mode of metastasis following peritoneal spread rather than hematogenous distribution. Adenocarcinoma ex-goblet cell carcinoid can spread to any peritoneal site including ovaries or omentum. We report a 37-year-old healthy woman who initially presented with right lower quadrant abdominal pain and pseudomyxoma peritonei. Histopathology of the appendectomy specimen revealed an adenocarcinoma ex-goblet cell carcinoid, signet ring cell type. Follow-up right hemicolectomy, omentectomy, bilateral salpingo-oophorectomy, and regional peritoneal resections revealed metastatic involvement by adenocarcinoma ex-goblet cell carcinoid, signet ring cell type. In this report, we describe a case of appendiceal adenocarcinoma ex goblet cell carcinoid with metastases to Meckel's diverticulum and areas of pelvic endometriosis, which have not been previously reported.

Tumors arising from Meckel's diverticulum (MD) reported in the literature are mainly carcinoid and gastrointestinal stromal tumors. We herein report a rare case of adenocarcinoma arising from intestinal mucosa in an MD with multiple liver metastases at the onset of symptoms. A 57-year-old female complaining of bloody stool for 2 weeks was admitted to our hospital. Colonoscopy revealed massive bloody fluids but did not find any neoplasm. Computed tomography (CT) found a heterogeneous mass at the distal ileum and multiple liver metastases. A segmental ileal resection with local mesentery excision was performed to control the bleeding. During surgery, a tumor arising from a diverticulum in the antimesenteric border of ileum was observed. Histologic examination revealed moderate to poorly differentiated adenocarcinoma. Majority of the MD remain asymptomatic and are diagnosed incidentally during small bowel contrast study, laparoscopy or laparotomy done for unrelated conditions, or until complications arise from the diverticulum. Malignancies are reported to account for only 0.5%-3.2% of the complications. The occurrence of adenocarcinoma in an MD is exceedingly rare. In the few cases described so far, the prognosis of adenocarcinoma within an MD has been poor due to the advanced stage as seen at the time of surgery. Despite the availability of many publications, there is a little consensus concerning the management of an incidental finding of MD. Adenocarcinoma in an MD is extremely sporadic and prognosis has been reported as very poor. However, early diagnosis is challenging. When found incidentally during laparotomy, MD should be carefully examined and best treated with prophylactic resection.
