ADRENAL CORTICAL ADENOMA
This 37 year old female had been hypertensive for at least 11 years (BP 240/140) and serum electrolytes showed an elevated sodium and depleted potassium and choride. These findings were consistent with excessive aldosterone secretion (Conn's syndrome). Peri-renal insufflation revealed this cortical tumour which was excised. The hypertension showed some improvement postoperatively.
The specimen is an adrenal gland sliced to display a round yellow tumour 3 cm in diameter lying within the capsule. The tumour resembles the normal adrenal cortex both macroscopically and histologically. It is an adrenal cortical adenoma.
