title: Ectopic decidual reaction mimicking inguinal lymphoma on ultrasound.
abstract: Ectopic decidual reaction has been described in various intraperitoneal locations. We present a case of unusual ectopic decidual reaction in the groin mimicking inguinal lymphoma on ultrasound in a pregnant woman. This case contributes evidence illustrating the variability of the clinical presentation of ectopic decidual reaction.
