Ultrasound-Guided Endometrial Aspiration and Immunohistochemistry for Detecting Focal Metastatic Cancer.

Overview

At our institution, we offer a one-step office endometrial evaluation using the simultaneous endometrial aspiration and sonohysterography (SEAS) method. This involves pelvic ultrasound and sonohysterography, followed by ultrasound-guided endometrial aspiration with the same catheter. The aspirated specimens are sent for histological analysis, and in difficult or inconclusive cases, immunohistochemistry (IHC) is performed to refine the diagnosis. In this manuscript, we present a case demonstrating the utility of ultrasound-guided endometrial aspiration supported by IHC. This method should be considered in the evaluation of focal endometrial lesions and/or persistent endometrial bleeding.
