7.4 POJA-L4179+4181+4182
Title: Invasive ductal mamma carcinoma, no special type (NST) (human)
Description: Stain: Hematoxylin-eosin.
(A): Survey of sheets and nests (1) of an invasive ductal carcinoma with focally luminization (2).
(B): Detail of A shows solid cell nests with tumor cells (1) varying from small cells with moderately hyperchromatic regular nuclei to lighter-stained polygonal cells with regular nuclei. Surrounding dense fibrous tissue at (2).
(C): Cords and sheets of large malignant epithelial cells (1) infiltrate in a disordered organization between bands of collagen. Tumor cells extend from the fibrous tissue into and replace adjacent adipose tissue (3).

Background: Invasive ductal carcinoma NST (no special type) includes the majority of invasive breast carcinoma (over 50 up to 80%). Most of these neoplasms show an increase in dense fibrous tissue stroma (scirrhous carcinoma). The tumor grows as fairly sharply delineated nodules (average 1 up to 2 cm). They may attach to their surroundings with fixation to underlying chest wall thus infiltrating elsewhere. Generally dimpled skin and retraction of the nipple occur.
Keywords/Mesh: breast, mammary glands, breast neoplasms, carcinoma, ductal, histology, POJA collection,
