Cytomorphological features of metastatic mammary lobular carcinoma in cervicovaginal smears: report of a case and review of literature

Uterine cervix metastasis from a sigmoid adenocarcinoma: a rare presentation of an uncommon tumor

Metastatic carcinoma to the uterine cervix from colorectal cancer, through haematogenous or lymphatic spread, is extremely rare. We report the case of a 59 year old woman in whom cervical metastasis was diagnosed after 13 months of follow-up for a sigmoid adenocarcinoma, confirmed by immunohistochemical study, with a review of the literature. This case illustrates that abnormal gynecologic symptoms can reveal a disease progression on patients who suffer colorectal cancer.

Metastatic colorectal adenocarcinoma in cervicovaginal cytology specimens confirmed by immunocytochemical stains on liquid base specimens: Two study cases with review of the literature

Only a few cases of adenocarcinoma (ACA) metastatic to the female lower genital tract diagnosed on cervicovaginal Pap smear have been reported during the past several decades. Both conventional and liquid based cytology (LBC) have limited sensitivity and specificity in diagnosing metastatic disease and immunocytochemical (ICC) staining may be needed for confirming the diagnosis. We present two cases of metastatic colorectal ACA diagnosed on cervicovaginal ThinPrep (TP) Pap smears, with one confirmed by ICC staining method. Recognition of extra-uterine malignancy in the cervicovaginal cytology specimen is critical for the disease diagnosis, prognosis, and the treatment. ICC staining performed on the residual LBC specimen is an important methodology to confirm the diagnosis.

Adenocarcinoma metastatic to the uterine cervix: a case series

AIMS

The objectives of this report are, first, to describe the clinical behavior of cases of carcinoma metastatic to the uterine cervix treated at our institution in order to carry out a systematic review to establish the behavioral patterns of the most frequent metastases to the cervix and, second, to generate guidelines for their diagnosis and treatment.

METHODS

At the National Institute of Cancer of Mexico (INCan), we performed a review of the clinical files with a diagnosis of malignant neoplasm metastatic to the uterine cervix between 1990 and 2009. For a systematic review, we conducted a PubMed search between the years 1970 and 2009 of case reports and series of cases of patients with metastatic gastric, breast, ovarian and colorectal cancer. We analyzed each report individually and extracted the patients' clinical data from our cases and reports, including the primary tumor, cervical metastases and survival rates.

RESULTS

There were 10 cases of tumors metastatic to the uterine cervix. Metastasis was documented in one-half of the patients during follow up, with two of these cases having the cervix as the only site. We included the following reports in the systematic review: 13 reports of gastric-associated cancer, 30 related to breast cancer, nine with ovarian-associated cancer and 10 related to colorectal cancer.

CONCLUSIONS

Metastatic cervical activity is an infrequent event. The prognosis of survival is poor in the presence of gastric or ovarian cancer and cervical metastases.

Primary signet-ring cell adenocarcinoma of the endometrium: case report and review of the literature

Endometrial adenocarcinoma presenting with deep venous thrombosis is an exceptional event more typical of extra-mullerian primary tumors. Metastases to the spleen are also unusual in this setting. In addition, primary endometrial adenocarcinoma with signet-ring cell features has been reported only once. This study describes a case of primary endometrial carcinoma with prominent signet-ring cell features that presented in an unusual manner: with bilateral deep vein thromboses and splenic metastases. It is important for clinicians and pathologists to be aware of this entity; it may have an atypical clinical presentation and the histologic features raise a spectrum of differential diagnoses.
