Percolated and Spiked-Medullary Carcinoma Breast

Abstract

Medullary pattern is a histological pattern discerned within invasive carcinoma breast no special type (NST) comprised of a ‘pushing’ tumour perimeter, syncytial pattern of tumour evolution, high grade nuclei and prominent stromal lymphocytic infiltrate. In contrast to a distinct morphological subcategory, medullary carcinoma breast is contemplated to represent a morphological continuum of tumour infiltrating lymphocyte (TIL) rich invasive carcinoma breast no special type (NST).
