Background: Multiple primary malignancies are two or more malignancies in an individual without any relationship between the tumors. The development of improved diagnostic techniques, increased survival of cancer patients and the growing life expectancy have all contributed to the increased frequency of this phenomenon.
Objective: The aim of this study is to review the multidetector computed tomography (MDCT) findings of synchronous breast carcinoma and other solid malignancies.

Introduction: It is well established that the PKHD1 mutations are associated with autosomal recessive polycystic kidney disease (ARPKD). Although, PKHD1 mutations are also detected in certain cancer types, to our knowledge in rare tumors such as, atypical teratoid rhabdoid tumor (ATRT), primary neuro-ectodermal tumor (PNET), atypicalchoroid plexus papilloma (a-CPP), amelanotic ano-rectal melanoma (AMM), and breast phyllodes tumors PKHD1 mutations profiling is not reported.
Methods: In order to determine the PKHD1 gene mutation patterns in the brain, rectal, and breast tumors we have analyzed these tumor DNA by Ion Proton Next generation DNA sequencing.
