Primary multiple neoplasms (polyneoplasia) are among the interesting and insufficiently studied fields of oncology. The term polyneoplasia is usually used for two or more malignant neoplasms in a single patient, which occur synchronously or metachronously. Over the last decade, an increase of primary multiple tumors prevalence has been observed. In 2015 39 195 new cases of primary multiple tumors were registered in Russia and comprised 6.7% of all incident malignant neoplasms. Primary multiple metachronous and primary multiple synchronous tumors with two neoplasms development are observed most often, with three more rarely, and with four or more very rarely. In average, 0.1% of a total number of oncologic patients have at least three malignant neoplasms. Primary multiple tumors of gastrointestinal tract are observed most often. The current article presents a clinical case of four synchronous tumors in a single patient localized in major duodenal papilla, sigmoid, transverse colon and lung.

The article contains description of such serious pathology in emergency surgery as bowel infarction caused by acute mesenteric ischemia in two patients with colorectal cancer admitted to Tatarstan regional clinical cancer center. Patients were admitted for emergency indications with the clinic of an acute abdomen. Both patients underwent an emergency surgery of laparotomy, enterectomy with colon resection and anastomosis. Both patients had satisfactory immediate postoperative results. One patient died 8 months later due to the progression of the underlying disease, the second one is alive to the present day with a satisfactory quality of life and the only complain of frequent loose bowel movements. Most patients with acute mesenteric ischemia are operated on with trial diagnostic laparotomy, and mortality rate for this pathology reaches 90% or more. The presented clinical cases familiarize physicians with an opportunity of successful surgical treatment of patients with acute mesenteric ischemia combined with colon cancer and demonstate expediency and need for surgical interventions with extensive colon resection.
