BRCA1 and serous adenocarcinoma: We have found one carcinosarcoma (epithelial component had morphology of serous carcinoma and sarcomatous component included chondrosarcomatous heterologus elements) with pathogenic mutations (tBRCA PVs were confirmed by gBRCA), and another carcinosarcoma (epithelial component had morphology of serous carcinoma) with VUS in BRCA1 gene.
