Pathology Image Detail

Caption

Mammary gland: the mammary gland is replaced by a nodular, unencapsulated, well-delineated, densely cellular, polycystic neoplasm. The neoplasm is composed of closely-packed branched papillae and glands supported by a small to moderate amount of fibrovascular stroma. A large amount of coarsely granular material (degenerated neoplastic cells) separate neoplastic papillae and fill neoplastic glands.
