Cholestatic Hepatitis as a Possible Paraneoplastic Syndrome of Endometrial Carcinoma.

Cholestatic hepatitis has not been reported as a paraneoplastic syndrome of endometrial adenocarcinoma to our knowledge. We present a patient who, shortly after endometrial adenocarcinoma diagnosis, presented with elevated liver chemistries in the setting of an acute, paraneoplastic sensorimotor polyneuropathy. Infectious, autoimmune, pharmacologic, malignant, metabolic, and structural causes of cholestatic hepatitis were screened for and ruled out. Our patient was diagnosed with simultaneous cholestatic hepatitis and acute sensorimotor polyneuropathy as possible paraneoplastic syndromes of endometrial adenocarcinoma. Clinicians should include paraneoplastic processes of cancer in the differential diagnosis for liver injury, especially when workup for alternative causes is unrevealing.
