Figure 6 : The structure of ducts of female (a) and male (b,c,d) mammary gland sections according to
H&E stain.

(a): Showing the duct is lined by stratified epithelium. The luminal cells are cuboidal with large central
rounded nuclei (n). The basal cells are flat with flat nuclei (arrow). Flat nuclei of fibroblasts (arrow head)
are seen in the fibrous stroma (FS). [H&E, X400. Bar, 100μm].
(b): Showing the large duct is lined by multiple layers of vacuolated large luminal epithelial cells (closed
arrow) with large rounded nuclei (arrow heads). Luminal and ductal necrotic cells (arrows) and
acidophilic secretion (S) are seen in the lumen. The fibrous stroma (FS) around the duct is thin. Large
unilocular adipocytes surrounded the fibrous stroma are noted. [H&E, X400. Bar, 100μm].
(c): Showing the small duct (LE) is surrounded by thick fibrous vascularized stroma (bv). [H&E, X400. Bar,
100μm].
(d): Showing the subtending duct is lined by vacuolated cells (v) with rounded nuclei (n). Very thin
stroma (arrow head), a few number of fibroblasts (arrow) and deeply acidophilic secretion (s) is seen.
[H&E, X400. Bar, 100μm].
