A 45-year-old woman presented with a short history of abdominal distension and features of intestinal obstruction. Computed tomography examination of the abdomen revealed a solid and cystic mass in the region of the left ovary, but spread within the abdomen was also noted. The ovarian tumor was removed, and an omentectomy was also performed. Microscopic examination of the ovarian tumor and metastases within the omentum showed a carcinosarcoma composed of borderline serous papillary cystadenocarcinoma and angiosarcoma. The angiosarcomatous component was the dominant tumor within the omentum. This case documents an unusual combination of epithelial and sarcomatous elements in an ovarian carcinosarcoma. The tumor behaved aggressively because of the angiosarcomatous component, and since the patient was assessed as having stage IV disease, no further treatment was offered.

A 48 years old man presented with subacute intestinal obstruction resulting from an intraluminal colorectal mass. He underwent partial colectomy. Histological diagnosis of mucinous adenocarcinoma with focal areas of heterotopic ossification was made. Although the presence of heterotopic ossification has no known prognostic implication in colorectal carcinoma, however, it is important that both radiologist and pathologist be aware of this phenomenon as distinct from carcinosarcoma that has poorer prognosis. From the available literature reviewed and to the best of our knowledge, this is the first reported case of mucinous colorectal carcinoma with heterotopic ossification in Saudi Arabia.

In this report we describe the case of a young woman with familial adenomatous polyposis who developed metastatic rectal cancer during pregnancy. At diagnosis, we decided to perform a transabdominal laparoscopic adrenalectomy, because of the high risk of bowel obstruction, and to define the origin of the adrenal gland lesion, suspected to be primary on the basis of imaging results. The histological specimen showed a collision tumor between an adrenal metastasis of a rectal tumor and a primary adrenal gland carcinosarcoma. The peculiarity of the case is due not only to its clinical presentation during pregnancy, but also to the presence of this uncommon adrenal collision tumor. A particular challenge for the clinician is to define the priority between these two tumors: the presence of two distinct and colliding aggressive neoplasms poses a problem in the choice of the best therapeutic approach, also given the impossibility to biopsy all metastatic sites. However, we decided to treat the patient as having a metastatic rectal cancer, because we had a solid histological confirmation of metastases.

Metastatic small bowel tumors are rarely encountered. They usually present with small bowel obstruction, perforation, bleeding, or, rarely, intestinal intussusception. Only a few case reports have mentioned bowel symptoms due to metastatic malignancies. We report a seldom encountered clinical condition of intestinal intussusception from metastatic lung malignancy. Pathology demonstrated both epithelial and mesenchymal content, and the final diagnosis was carcinosarcoma. This case report indicates that intestinal metastases should be considered in the differential diagnosis for patients with lung malignancy and abdominal symptoms.
