Pathology Image Detail

Caption

Mammary gland: the mammary gland is expanded by a large, multilobular, densely cellular neoplastic mass surrounded by a thin capsule. The neoplasm is composed of closely-packed branching glands with an inconspicuous lumen. These glands are lined by a one cell-thick epithelium and are supported by a small amount of fibrovascular stroma. A few areas of liquefactive necrosis are scattered throughout the neoplasm.
