Q

adrenogenital syndrome

A

impaired synthesis of both cortisol and aldosterone

increased secretion of adrenocorticotropic hormone, resulting in adrenal hyperplasia and increased synth of testosterone

Other causes of chronic adrenal insufficiency

A

TB, autoimmune, hemochromatosis

also tumors or suppresion of hypothalamus

17
Q

adrenal cortex neoplasms

A

adenoma

carcinoma

18
Q

adrenal medulla neoplasms

A

neuroblastoma

pheochromocytoma

19
Q

adrenal cortical adenoma

A

most are silent
well circumscribed, 2.5 cm
if functional, opposite gland atrophic
if nonfunctional, opposite gland normal

20
Q

yellow adrenal adenoma

A

cortical

21
Q

adrenal cortical carcinoma

A
very uncommon
children or adults
>90% functioning
big ones are malignant
no mitoses, no anaplasia - bland
22
Q

neuroblastoma

A

most common extracranial solid tumor in children
650/yr in US
adrenals and paraaortic ganglia are most common sites

red tumor, surrounded by a ring in adrenal medulla

23
Q

pheochromocytoma

A

red tumor surrounded by ring in adrenal medulla

10% neoplasm
episodic htn
histology nonpredictive

24
Q

pheochromocytoma “10% neoplasm” items (5)

A
familial
extra-adrenal
bilateral
malignant
in childhood
25
Q

paraganglion system

A

sites of paraganglion cell nests where neoplasms may form. cervical, mediastinum, along aorta, down to iliacs & bladder

26
Q

most common types of adrenal neoplasms

A

metastatic (lung, breast, many others)

multifocal = usually mets
