Signet-Ring Cell Carcinoma

Risk factors for ovarian metastasis following curative resection of gastric adenocarcinoma

“…19 -21 In cases of gastric carcinoma, ovarian metastases appear to be more frequently detected in Laurén diffuse type than in intestinal type. 4 However, these data were based on descriptive studies of a relatively small number of patients, and no multivariate analysis was performed. We therefore undertook this retrospective multivariate analysis to define the risk factors for metachronous ovarian metastasis.…”

Krukenberg Tumor of Renal Pelvic Origin: Report of a Case With Selected Comments on Ovarian Tumors Metastatic From the Urinary Tract

“…The only previously reported urinary tract malignancy associated with Krukenberg tumors is signet-ring cell carcinoma of the urinary bladder (3,4,6,7). It is well known that signet-ring cell carcinomas have a greater propensity to metastasize to the ovary than carcinomas without signet-ring cell morphology (8,9). This is reflected by the fact that four of five urinary bladder adenocarcinomas of nonurachal origin with ovarian spread have been signet-ring cell carcinomas (3,4,6,7).…”

Urachal adenocarcinoma metastatic to the ovary simulating primary mucinous cystadenocarcinoma of the ovary: report of a case

“…Spread of urinary tract tumours of other types to the ovary is rare. Four of the five adenocarcinomas of the bladder with ovarian spread have been signet ring cell carcinomas [2,3,10,21], illustrating the propensity that Saphir [11] emphasized many years ago for signet-ring cell carcinomas from diverse sites to spread to the ovary more frequently than adenocarcinomas of other types. One of these cases is noteworthy because the primary bladder tumour was not discovered until autopsy [2], and another because the ovarian metastasis did not occur until 7 years after the primary bladder tumour had been resected [21].…”
