• 
  This is a gross photograph of the surgical specimen of breast with infiltrating duct carcinoma. Note the tumor tissue under the area of the nipple. The tumor infiltrates in an irregular fashion into the breast parenchyma. Note the nipple retraction caused by this neoplasm.
• 
  These are sections of normal breast (lower) and breast tissue with infiltrating duct carcinoma (upper). Note the increased cellularity (increased blue staining due to the increased number of nuclei) in the tumor tissue.
• 
  This is a section of breast with small groups of carcinoma cells throughout the breast tissue and invading through the dermis.
• 
  This is a higher-magnification showing abundant groups of tumor cells dissecting through the breast parenchyma - tumor infiltration (infiltrating duct cell carcinoma).
• 
  This is a high-power photomicrograph showing the cellular and nuclear features of the tumor cells. The large epithelial cells form glands and are medium-sized with a moderate amount of cytoplasm, vesicular nuclei, and nucleoli.
• 
  This is a section of breast tumor with abundant fibrous tissue throughout the tumor (desmoplasia, scirrhous carcinoma).
• 
  This is a section taken at the periphery of the tumor showing bands of tumor cells infiltrating into the fat tissue.
• 
  This is a high-power photomicrograph demonstrating the growth pattern of the tumor. The tumor consists of malignant duct-lining cells growing in cords, solid cell nests, tubules, and glands. The cytologic detail of tumor cells varies from small cells with moderately hyperchromatic, regular nuclei to large cells with large, irregular, hyperchromatic nuclei.

An infiltrate is an accumulation of cells in the lung parenchyma--this is a sign of pneumonia.
