Primary peritoneal tumors are rarely encountered and their management is usually challenging for the clinicians. Especially when the patients with advanced peritoneal malignancy present as surgical emergencies, usually with symptoms of obstruction, perforation or gross space-occupying lesions, the on-call surgical team has to weigh the pros and cons of urgent versus delayed treatment and plans a safe and simultaneously oncologically beneficial therapeutic approach. Herein, we present a case of a Caucasian man who was referred as suspected complicated appendicitis by his primary care physician, with the final diagnosis being benign multicystic mesothelioma. We describe the challenges of the clinical decision making for the emergency general surgeon and relevant diagnostic and therapeutic pitfalls, which can be potentially minimized by early liaison with tertiary units specializing in the treatment of disseminated peritoneal malignancy.
