Abstract

Krukenberg tumors (TK) define themselves as ovarian metastases from cancer more often digestive. These are rare tumors that represent 1 to 2% of ovarian tumors. They are characterized by the presence of “kitten ring” cells filled with mucus and a pseudo-sarcomatous proliferation of the ovarian stroma. Their evolution is quickly fatal. We report 1 case of Krukenberg tumor observed and operated on in June 2020 at the surgery Department B CHU Constantine. The symptoms began with a rectal syndrome with transient episodes of pelvic pain. In this regard, we will recall the epidemiological, clinical, and evolutionary characteristics of this disease. Keywords: Krukenberg tumor, rectal cancer, ovarian metastases, synchronous tumors, posterior pelvectomy.

Highlights

Krukenberg tumor is a metastatic malignancy of the ovary characterized by mucin-rich signet-ring adenocarcinoma that primarily arises from a gastrointestinal site in most cases and less commonly from other sites, usually solid and mostly detected bilaterally.The time from diagnosis of the primary neoplasm to the development of ovarian metastasis is variable and can range from several months to more than10 years

tumeurs de Krukenberg (TK) is an ovarian metastasis of a muco-secreting digestive cancer in 90% of cases; this can be gastric (70%) or colic (14%) or pancreatic and biliary (60%), or even appendicular (1 - 2.5%) [1, 2, 5, 7, 8, 9, 10] or recto sigmoid as in the case of our patient, an extra - digestive point of departure is rare; cases of primary TK have been described [5, 2, 9, 11] and we only speak of primary TK after 5 years of progression without recurrence

Summary

INTRODUCTION

Krukenberg tumor is a metastatic malignancy of the ovary characterized by mucin-rich signet-ring adenocarcinoma that primarily arises from a gastrointestinal site in most cases and less commonly from other sites, usually solid and mostly detected bilaterally. A requested MRI showed the tumor process of the middle and lower rectum respecting the anorectal junction with invasion of the perirectal fat opposite. Mots clés : Tumeur de Krukenberg, cancer rectal, métastases ovariennes, tumeurs synchrones, pelvectomie postérieure. MRI made objectifying the known tumor process of the upper and middle rectum measuring 13 mm thick and 47 mm high (downsizing), located 40mm from the anorectal junction and 85 mm from the anal margin, a bulky right ovarian abdominopelvic multilocular cystic mass measuring 230 * 135 over a height of 222 mm, probably a secondary location, and ascites of great abundance with probable peritoneal carcinoma. Pathological examination of the operative specimens with an immunochemical study concluded to: Krukenberg tumors of the ovary rectal origin (adenocarcinoma)
