Pathology Image Detail
Caption |
Mammary gland: the neoplasm is composed, at its' periphery, of radiating frond-like structures resembling terminal end buds of the developing mammary gland separated by a small to moderate amount of moderately dense stroma. Neoplastic cells are cuboidal to polygonal, with indistinct cell borders and a small amount of amphophilic cytoplasm. The nucleus is central, small, round to oval, slightly hypochromatic, with a stippled chromatin and 1-2 small basophilic nucleoli. Anisokaryosis and anisocytosis are mild. |

Type P tumor (uncommon variant), mammary gland |

Notes |
Type P tumors are characterized by the formation of frond-like structures that resemble terminal end buds of the mammary gland. This tumor is unusual in that the fronds are smaller although more numerous than usual, and that ductal differentiation is less conspicuous than in most type P tumors. |
