Synchronous Malignancies: Pathological Analysis of Three Patients, Each with Dual Malignancies

Abstract

Multiple primary malignancies are defined as two or more malignancies arising independently to each other in the same or different anatomical sites, while excluding the possibility of metastasis from the primary malignancy. Here, we present three cases, each with dual malignancies involving different anatomical locations.
