Figure 2: Numerous malignant glands are arranged in tubular and cribriform patterns surrounded by cellular fibromyxoid stroma. The glands are lined by single to multilayered glandular cells (a: H and E, ×40; b: H and E, ×100). The malignant glands display the absence of myoepithelial cells (c: p63, ×40; d: S100, ×40) with positivity toward ER (e: ER, ×40) and PR (f: PR, ×40). ER: Estrogen receptor (ER), PR: Progesterone receptor
