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. These frond like structures are cavitated and resemble ducts that show various degrees of dilation towards the center of the neoplasm. |
Description |
Type P tumor (uncommon variant), mammary gland |

364 days |
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. |
