Few studies reported patients who harbored three kinds of primary tumors simultaneously. Here, we present a 9-year-old boy with colon carcinoma, brain medulloblastoma, and lymphoma. Genetic mutation detection was explored with next-generation sequencing, and compound heterozygous mutations in gene MSH6 c.3103C>T p.Arg1035Ter and c.3261dupC p.Phe1088LeufsTer were discovered.
