MUCINOUS CYSTADENOMA OF THE APPENDIX AS THE CAUSE OF PSEUDOMYXOMA OF THE PERITONEUM (CLINICAL CASE)

Abstract

Diseases of the appendix remains an actual problem in abdominal surgery. Some of them are rare pathological processes and are difficult to diagnose and surgical treatment. The mucocele of the appendix is a rare, more often benign neoplasm, developing by widening the lumen of the appendix due to excessive accumulation of mucin. One of the most dangerous complications of a mucocele is a spontaneous or iatrogenic rupture with the development of a peritoneal pseudomyxoma (mucinous carcinomatosis), as a result of the dissemination of goblet cells, which are fixed in abdominal flanks and produce mucin. Article presents a case report of a 32-year-old patient with mucinous cystadenoma of the appendix and developed of peritoneal pseudomyxoma, who underwent laparoscopy with a conversion to a total laparotomy, right hemicolectomy, resection of the greater omentum and terminal ileostomy. Results of immunohistochemistry: highly differentiated neuroendocrine tumor, germinating all tissues of the appendix, spreading on adipose tissue. Patient was discharged on the 10th day in a satisfactory condition. НАУЧНЫЕ ВЕДОМОСТИ Серия: Медицина. Фармация. 2019.
