LOW-GRADE ADENOSQUAMOUS CARCINOMA Figure 8-59 LOW-GRADE ADENOSQUAMOUS CARCINOMA A: At low power, subtle cords, glands, and nests of epithelial cells are seen haphazardly placed in the stroma. Scattered lymphoid aggregates are present. B,C: Some nests have a squamoid appearance (B) and others More about this image found in LOW-GRADE ADENOSQUAMOUS CARCINOMA A: At low power, subtle cords, glands, a...

SYRINGOMATOUS TUMOR Figure 13-11 SYRINGOMATOUS TUMOR A: At low power, predominantly solid nests of tumor cells are seen percolating through the dermis of the nipple. B–D: Increasing magnification of areas of the tumor showing solid nests of tumor cells (B) with some squamoid features within More about this image found in SYRINGOMATOUS TUMOR A: At low power, predominantly solid nests of tumor ce...

appears eosinophilic. There is a gradual transition between the more normal-appearing squamous cells and the malignant cells. C: At high power, more squamoid-appearing features are seen, including possible keratinization. This case had initially been diagnosed as Paget disease; upon secondary review More about this image found in SQUAMOUS CELL CARCINOMA IN SITU A: At low power, sheets of malignant-appea...

with the papilloma. B: At higher power, the greater stromal cellularity and stromal cell atypia are more obvious. C: The cytologic atypia is striking at high power; in some areas the spindled cells are more epithelioid or squamoid in appearance. D: Mitotic activity is brisk. While the presence of a collagenous More about this image found in METAPLASTIC CARCINOMA ARISING IN BENIGN INTRADUCTAL PAPILLOMAS A: At low p...

CYSTIC ADVENTITIAL DISEASE Figure 31-21 CYSTIC ADVENTITIAL DISEASE Left: Elastic staining of this popliteal artery shows numerous cysts within the adventitial space. Right: High-power evaluation of the adventitial cysts shows blood and amorphous debris within the space surrounded by squamoid More about this image found in CYSTIC ADVENTITIAL DISEASE Left: Elastic staining of this popliteal artery...

MALIGNANT BRENNER TUMOR Figure 9-11 MALIGNANT BRENNER TUMOR Left: Irregularly shaped nests of malignant squamoid cells in desmoplastic stroma is typical. A benign or borderline Brenner component should be present (not shown) to confirm Brenner lineage. Otherwise, squamous cell carcinoma More about this image found in MALIGNANT BRENNER TUMOR Left: Irregularly shaped nests of malignant squamo...

PANCREATOBLASTOMA Figure 10-9 PANCREATOBLASTOMA The immunolabeling of squamoid nests is somewhat variable. Occasionally, they are positive for chromogranin A (A) or CEA (B). More consistently, epithelial membrane antigen is expressed (C). More about this image found in PANCREATOBLASTOMA The immunolabeling of squamoid nests is somewhat variabl...
