ADRENAL CORTICAL CARCINOMA: ULTRASTRUCTURE Figure 6-29 ADRENAL CORTICAL CARCINOMA: ULTRASTRUCTURE A: Tumor cells contain sparse lipid droplets; some have small, irregular microvillous extensions of cytoplasm along the cell border. The cells contain ample mitochondria and smooth endoplasmic More about this image found in ADRENAL CORTICAL CARCINOMA: ULTRASTRUCTURE A: Tumor cells contain sparse l...

GANGLIONEUROMA Figure 11-40 GANGLIONEUROMA Gross image of bisected tumor 9 cm in diameter, with a smooth, glistening, tan-yellow surface. The tumor is well-circumscribed on the outer aspect.

DORSAL ASPECT OF FETAL ADRENAL GLANDS Figure 1-17 DORSAL ASPECT OF FETAL ADRENAL GLANDS The dorsal surface of both adrenal glands from a 35-week premature infant shows a ridge (or crista) and a relatively smooth cortical surface. Each gland weighed 3 g. More about this image found in DORSAL ASPECT OF FETAL ADRENAL GLANDS The dorsal surface of both adrenal g...

DISTINCTIVE ARCHITECTURE OF THE CENTRAL VEIN IN NORMAL ADRENAL GLAND Figure 1-45 DISTINCTIVE ARCHITECTURE OF THE CENTRAL VEIN IN NORMAL ADRENAL GLAND Distinctive arcades of interrupted smooth muscle form the wall of the central adrenal vein and its tributaries. The vein is surrounded More about this image found in DISTINCTIVE ARCHITECTURE OF THE CENTRAL VEIN IN NORMAL ADRENAL GLAND Disti...

PROTRUSION OF NORMAL CORTICAL CELLS INTO THE LUMEN OF THE CENTRAL VEIN Figure 1-46 PROTRUSION OF NORMAL CORTICAL CELLS INTO THE LUMEN OF THE CENTRAL VEIN Where smooth muscle is deficient, chromaffin or cortical cells may come into close proximity with the vascular space and can form More about this image found in PROTRUSION OF NORMAL CORTICAL CELLS INTO THE LUMEN OF THE CENTRAL VEIN Whe...

ALDOSTERONE-SECRETING ADRENAL CORTICAL ADENOMA Figure 4-27 ALDOSTERONE-SECRETING ADRENAL CORTICAL ADENOMA A: The tumor has expansile smooth borders that compress adjacent adrenal parenchyma and expand the adrenal capsule. B: The borders of the adenoma are sharply demarcated from the adjacent More about this image found in ALDOSTERONE-SECRETING ADRENAL CORTICAL ADENOMA A: The tumor has expansile ...

ALDOSTERONE-SECRETING ADRENAL CORTICAL ADENOMA Figure 5-47 ALDOSTERONE-SECRETING ADRENAL CORTICAL ADENOMA A: The tumor cells have much smooth endoplasmic reticulum and a few lipid droplets, which vary in size. Microvillous cytoplasmic extensions are evident along the cell borders. Mitochondria More about this image found in ALDOSTERONE-SECRETING ADRENAL CORTICAL ADENOMA A: The tumor cells have muc...

There is prominent smooth endoplasmic reticulum as well as a few free polyribosomes. More about this image found in ADRENAL CORTICAL ADENOMA IN CUSHING SYNDROME A: A nuclear pseudoinclusion ...

cells with chromaffin cells, and both the cortex and medulla have a close anatomic relationship with the vascular space due to discontinuity of smooth muscle in tributaries of the central adrenal vein vessel walls.

lipid droplets and abundant smooth endoplasmic reticulum. In the zona reticularis (C), cells are relatively depleted of lipid droplets. Lysosomes and lipofuscin granules are prominent, corresponding to the brown pigment seen in routine light microscopy.
