ABSTRACT Primary signet-ring cell carcinoma (SRCC) of the breast is an uncommon variant, accounting for 2-4.5% of all primary breast cancers. Secondary SRCC of the endometrium is very rare and usually originates from the breast or gastrointestinal tract. A 54-year-old, postmenopausal woman with a past history of breast cancer four years previously was admitted with abnormal uterine bleeding. An endometrial biopsy revealed undifferentiated adenocarcinoma with signet-ring cells. The patient underwent laparotomy and cytoreductive surgery was performed. Pathological analysis and immunohistochemical tests demonstrated a uterine (endomyometrial) metastasis of breast SRCC. Omentum, peritoneal surfaces and retroperitoneal lymph nodes also included tumoral tissue with signet-ring cell morphology. The patient received adjuvant systemic chemotherapy with adriamycin, cyclophosphamide and paclitaxel. This case report discusses the patient's clinical characteristics and the role of cytoreductive surgery on patient survival in SRCC of the breast metastasizing to the uterus.

    ABSTRACT: This report is an analysis of 63 cases of metastatic cancers to the uterine corpus from extragenital neoplasms. The patients' ages ranged from 34-88 years (mean, 59.7 years). Twenty lesions were discovered in surgical specimens and 43 were detected at autopsy. The primary tumors arose in the breast (42.9%), colon (17.5%), stomach (11.1%), pancreas (11.1%), gallbladder (4.8%), lung (4.8%), cutaneous melanoma (3.2%), urinary bladder (3.2%), and thyroid (1.6%). In five (25%) of the surgical cases, uterine metastases were the first indication of the presence of an extragenital primary cancer. Metastases to leiomyomas were found in 13 instances. The myometrium was more often involved than the endometrium, but endometrial curettings contained the metastatic tumor in numerous cases. Metastases to the ovaries were detected in almost two thirds of cases. Although an infrequent event, abnormal uterine bleeding may result from secondary spread to the uterine corpus from an extragenital primary neoplasm.

    ABSTRACT: Primary signet ring cell carcinoma of the breast is a very rare tumour. We present a case with pure signet ring cell carcinoma of the breast, which was recognized as metastasis on the pelvic floor, before developing breast symptoms and signs. A 40-year old woman was admitted with abdominal pain. First diagnostic effort revealed a cystic mass on the pelvic floor, compressing the colon and other neighbouring organs. A biopsy of the pelvic mass was performed. The histopathological examination revealed metastatic signet-ring cell carcinoma. At the time of the first operation, the mammary glands were not suspicious. No other sources of primary tumour were evidenced. An inflammatory sign developed in right breast two months after biopsy of the pelvic metastasis. The histopathology of the breast incisional biopsy revealed primary pure signet ring cell carcinoma of the breast. Because the oestrogen and progesterone receptor were negative in the tumoral tissue, the patient underwent chemotherapy followed by modified radical mastectomy, chemotherapy, and palliative resection of the metastatic mass. The patient was followed up for eight months. To our knowledge, in English literature, we believe that this case is the first report of signet ring cell carcinoma of the breast presenting with pelvic floor metastasis without breast sign.

    ABSTRACT: Signet ring carcinomas of the breast have been separated recently as an aggressive subtype of breast cancer, distinct from mucinous (colloid) carcinomas. Twenty-four cases of signet ring breast cancer (2% of total breast cancers at the authors' institution) were analyzed. The authors' study indicates that histogenetically such lesions are derived from lobular, not ductal, cells since mucin patterns and ultrastructural features are shared. In addition, in each of our 24 cases, infiltrating lobular carcinoma was identified; in 11 of these (46%) lobular carcinoma in-situ (LCIS) was also noted. Signet ring carcinomas show an unusual metastatic pattern with a propensity to involve serosal surfaces and mimicking gastrointestinal disease or retroperitoneal fibrosis. These tumors are associated with a poor prognosis, with 60% of our 24 patients dead of disease at 7 years. The distinctive clinical and pathologic features of signet ring carcinoma warrant separation of this group of tumors from other forms of breast cancer.
