We describe the case of a young patient who contracted fatal herpes simplex virus hepatitis following neoadjuvant chemoradiotherapy and anterior resection for rectal cancer. The rarity and non-specific presentation of this treatable disease, which masqueraded as the sequelae of postoperative sepsis, resulted in a diagnosis following death. Features that should prompt inclusion of herpes simplex virus hepatitis in the differential diagnoses are suggested and the case is a reminder of how neoadjuvant therapy may subtly alter a patient's immunocompetency.
