Mammary gland: at its' periphery, the neoplasm formed hollow frond-like structures that contained a proteinaceous fluid with a few degenerated neoplastic cells. In these areas, the basal layers of the neoplastic epithelium clearly showed nuclear palissading. |

Adenocarcinoma, glandular, acinar, cystic, solid with secondary lumens, mammary gland |
Age at Necropsy |

Notes |
This tumor forms fronds that are reminiscent of fronds observed in type P tumors. However, this neoplasm differs from type P tumors in that the mitotic activity is not most important at the tip of the fronds and ductal differentiation with squamous metaplasia are absent. |
