In older women, it appears as a mammographic density or clustered calcification . Epithelial component is hormonally responsive . Typically increase in size due to lactational changes during pregnancy . Gross features * There is a well-circumscribed, rubbery grayish white nodules * Measurement 2.5 cm x 4.5 cm in dimension * Pressing the surrounding normal breast tissue 4/16/2025 2
Microscopic features . Composed of both epithelium & fibrous stromal components . Epithelium components form glandular structures, lined by mammary duct-type epithelium . The stromal component is a loose, cellular form of fibrous tissue In very large mass stromal may be myxomatous . Two patterns of growth 1. Pericanalicular pattern: . the epithelial component takes the form of rounded ducts which remain small & undistorted. . The stroma arranged round them in a roughly symmetrical and regular manner. 2. Intracanalicular pattern: . The ducts appear elongated but actually represent sections cut through flattened spaces . Compressed by stromal component which appears to proliferate in an irregular nodular manner. 4/16/2025 4
