The Role of Next Generation Sequencing in the Differential Diagnosis of Composite Neoplasms

Composite neoplasms (CN) are rare and diagnostically challenging lesions that require differentiating between mixed clonal tumors with divergent phenotypes (MT), collision of two independent tumors adjacent to each other (CT) and tumor-to-tumor metastasis (TTM). To that end, pathologists have traditionally used Immunohistochemistry and limited molecular studies, such as Sanger sequencing. Herein we evaluate the potential application of NGS in the differential diagnosis of these rare neoplasms. Four CNs were included in the study.
