Primary adenocarcinoma of the gallbladder presenting as primary gynecologic malignancy: a report of two cases.
BACKGROUND: Carcinoma metastatic to the uterus from extragenital sites is rare. Such metastatic disease is typically diagnosed at autopsy or in patients with known primary malignancies. This report discusses two cases of primary carcinoma of the gallbladder presenting as abnormalities in gynecologic screening procedures. CASES: A 71-year-old woman presented with postmenopausal bleeding. Uterine curettage revealed poorly differentiated adenocarcinoma of presumed endometrial origin. Intraoperative frozen-section analysis of the uterus showed carcinoma involving the lymphatics, but no primary tumor. Further exploration revealed primary adenocarcinoma of the gallbladder, with widespread metastases. The second case was a 67-year-old asymptomatic woman. Routine cervical cytology showed adenocarcinoma, but tissue studies were negative. She developed jaundice 1 month later. Computed tomography of the upper abdomen revealed a mass in the gallbladder fossa, and needle biopsy of the lesion showed adenocarcinoma. CONCLUSIONS: Metastatic carcinoma of non-genital tract origin may present as primary gynecologic malignancy. The physician should be aware of the implications of both the common and unusual interpretations of screening and diagnostic procedures. When the clinicopathologic presentation is atypical, a thorough knowledge of the differential diagnoses of abnormal test results allows appropriate and expeditious patient management.
