Abstract:
This article describes a rare presentation of squamous cell carcinoma of the lung, mimicking an ectopic pregnancy secreting beta-hCG protein in a 47 year old female smoker, who was treated with Methotrexate and subsequently curettage, tubectomy and right ovariectomy, because of suspected hydatidiform mole. This document presents a rare and chaotic case of lung cancer and reviews the differential diagnosis of an increased level of the beta-hCG marker and the therapeutic approach to these cases.
