A proportion of tumour cells are arranged in cords, clusters and trabeculae (HE ×10), B- Poorly differentiated serous carcinoma glandular and papillary architecture of tumour. The glands are typically irregular and slit-like (HE ×10), C- Intraductal carcinoma with cribriform and micropapillary pattern (HE ×40), D- Undifferantiate neuroendocrine carcinoma; sheets of polygonal, round cells with salt and pepper nuclei and numerous mitotic figures (HE ×10).
