a High-power magnification of breast lump biopsy showing spindle cell lesion arranged in storiform pattern dissecting collagen fibers. No nuclear atypia, necrosis, or mitosis is seen. (H&E × 400). b Low-magnification view of breast tissue showing large lactiferous duct with a papillary lesion exhibiting papillary structures with central fibrovascular cores. (H&E × 100). c High-magnification view of a papillary lesion exhibiting papillary structures with central fibrovascular cores, lined by dual epithelial and myoepithelial cell layers. (H&E × 200). d High-magnification view of lactiferous duct exhibiting solid/cribriform pattern with irregular cleft like spaces separated by proliferating epithelial and myoepithelial cell layers. These cells show minimal variation in size and shape. No necrosis is seen. (H&E × 200)
