Differential diagnosis:
This could be confused with other glands sucha s the live. The liver cells are arranged in plates and cords. The parathyroid is smaller and has no distinct zonation. Other glands have spaces such as thyroid, pancreas, etc.

Diagnostic Features:
a. Tissue is compact (e.g. liver)
b. It consists of glandular tissue judging from rich parenchyma with minimal spaces.
c. Long and straight cords running from capsule to medulla is the haulmark of its diagnosis. Cell cords in the zonae glomerulosa and reticularis are wider apart than in the remaining zone (fasciculata). Under low power magnification the zona reticularis are seen as dark as capsular covering. There is more space in medulla representing high vascularization.
