ADRENAL MEDULLARY HYPERPLASIA Figure 8-59 ADRENAL MEDULLARY HYPERPLASIA Adrenal glands from patients with MEN2 (A) and SDHB-related disease (B) show diffuse expansion of the medulla that is much larger than the adrenal cortex on either side. While this is considered to be diffuse hyperplasia More about this image found in ADRENAL MEDULLARY HYPERPLASIA Adrenal glands from patients with MEN2 (A) a...

ADRENAL MEDULLARY HYPERPLASIA IN A PATIENT WITH MEN2A Figure 8-60 ADRENAL MEDULLARY HYPERPLASIA IN A PATIENT WITH MEN2A A: The adrenal medulla is mildly, diffusely thickened and extends into the alae of the gland. A single grossly discernible nodule (arrow) is the clue to the hereditary disease More about this image found in ADRENAL MEDULLARY HYPERPLASIA IN A PATIENT WITH MEN2A A: The adrenal medul...

NODULAR ADRENAL MEDULLARY HYPERPLASIA IN A PATIENT WITH MEN2A Figure 8-61 NODULAR ADRENAL MEDULLARY HYPERPLASIA IN A PATIENT WITH MEN2A A: The adrenal medulla is diffusely thickened and contains multiple nodules.

BODY AND HEAD OF A NODULAR ADRENAL GLAND Figure 1-24 BODY AND HEAD OF A NODULAR ADRENAL GLAND In this architecturally distorted gland in transverse section, the adrenal cortex is bright yellow, with focal nodularity. Medullary tissue is prominent and extends into both wings (alae) of the gland More about this image found in BODY AND HEAD OF A NODULAR ADRENAL GLAND In this architecturally distorted...

of neuroendocrine cells and nerve fibers is potentially mistaken for perineural infiltration by paraganglioma, medullary thyroid carcinoma, or other tumors. Paragangliomas arising from normal paraganglia in or near the thyroid gland are especially likely to be mistaken for medullary thyroid carcinoma.

medullary precursors (same specimen as fig. 9-3 ). B: In this unusual specimen cells from an extra-adrenal paraganglion are being incorporated into adjacent developing adrenal tissue, which also contains typical nests of neuroblast-like medullary progenitors.
