Which of the following is true of invasive lobular carcinoma?

Board review answer 1.
Carcinoma lobulillar invasivo – Diagnóstico y tratamiento – Mayo Clinic
Is most commonly associated with cytoplasmic p immunostaining; invasive lobular carcinomas commonly have a CDH1 germline mutation, causing the cells to lose membranous E-cadherin staining and carcinnoma in cytoplasmic p expression.
