Adrenal Gland - Infarct

Adrenal gland, Cortex - Infarct in a female F344/N Rat from a chronic study. There is a focal, acute infarct in the adrenal cortex characterized by a wedge-shaped zone of necrosis.

comment:
Infarction of the adrenal gland may be associated with local tissue or vascular damage, hypercoagulation, or any other cause of thrombosis. Thus, sporadic infarction of the adrenal gland may occur as a background lesion. Adrenal infarction may be focal or multifocal, and acute or chronic. Acute adrenal infarction results in coagulative necrosis in a characteristic wedge-shaped lesion ( Figure 1

recommendation:
Infarcts should be diagnosed as infarcts rather than diagnosing the individual components (e.g., necrosis, inflammation, fibrosis). They should be graded according to the extent of adrenal gland involvement. In the pathology narrative, infarcts should be designated as either acute or chronic, and if possible, the cause of the infarct should be identified.references:
