Pure Uterine Lipoma and Focal Nodular Hyperplasia of the Liver: Concurrence of a Rare Tumor and Another Incidental Finding.

Abstract

Background: Fatty uterine tumors, especially pure uterine lipoma, are very rare, but clinically and radiologically, they can mimic other primary benign and malignant uterine neoplasms. Case Report. A multipara 61-year-old postmenopausal woman presented with abnormal vaginal bleeding for 3 months. Assessment by ultrasound and magnetic resonance imaging (MRI) revealed a hyperechoic mass in the uterine corpus. Furthermore, during radiologic investigation, there was an incidental isoechoic mass in the left lobe of the liver. Pure uterine lipoma and hepatic focal nodular hyperplasia were diagnosed.

Conclusion: Pure lipoma of the uterus, even though rare, has to be kept in the differential diagnosis of uterine neoplasms, especially in postmenopausal women. Till now, just a few concurrent tumors have been reported with pure uterine lipoma, and among them, FNH is the first extragenital tumor.
