A Case of Metachronous Triple Carcinoma with Synchronous Double Primary Carcinoma on 18F-Fluorodeoxyglucose Positron Emission Tomography-Computed Tomography.

Multiple primary malignancies in a single patient are exceedingly rare, but their prevalence has increased in recent decades due to prolonged survival rates supported by the advent of newer and better generation of chemotherapeutic agents as well as advances in cancer detectability facilitated by sophisticated modalities such as positron emission tomography-computed tomography. Here, we discuss a case of a 66-year-old male who recovered completely from lung carcinoma but subsequently developed synchronous gall bladder and gastric carcinoma after 1 year.
