JUVENILE (CAPILLARY) ADRENAL HEMANGIOMA Figure 12-9 JUVENILE (CAPILLARY) ADRENAL HEMANGIOMA A,B: Small juvenile hemangioma of the adrenal gland in a newborn. There were numerous cutaneous hemangiomas and a large vascular tumor of the liver with identical histology. The adrenal tumor is uniformly More about this image found in JUVENILE (CAPILLARY) ADRENAL HEMANGIOMA A,B: Small juvenile hemangioma of ...

PRIMARY ADRENAL HEMANGIOMA Figure 12-7 PRIMARY ADRENAL HEMANGIOMA A: The subcortical area has a delicate capillary pattern, while more central areas are cavernous and have nonendothelial supporting cells. Fibrin thrombi are also present. B: The more cavernous pattern, with dilated vascular More about this image found in PRIMARY ADRENAL HEMANGIOMA A: The subcortical area has a delicate capillar...

PRIMARY ADRENAL HEMANGIOMA GROSSLY MIMICKING A RESOLVING HEMATOMA Figure 12-6 PRIMARY ADRENAL HEMANGIOMA GROSSLY MIMICKING A RESOLVING HEMATOMA A: The gross appearance of this retracted fibrinous and hemorrhagic lesion is suggestive of a resolving hematoma.

HEMANGIOMA Figure 11-20 HEMANGIOMA Low-power (A) and high-power (B) views of a large hemangioma excised from the breast. The vessel walls are thicker than in smaller perilobular hemangiomas. The endothelial cells are small and bland. More about this image found in HEMANGIOMA Low-power (A) and high-power (B) views of a large hemangioma ex...

PERILOBULAR HEMANGIOMA Figure 11-19 PERILOBULAR HEMANGIOMA A: Low-power view illustrates a proliferation of small vessels adjacent to a terminal duct lobular unit. B: High-power view demonstrates the thin vessel walls and the presence of red blood cells within the vascular lumen.
