Background:
Acromegaly secondary to growth hormone-releasing hormone (GHRH) excess is rare.
Aims/Case Description:
We report two patients with acromegaly who were diagnosed with sellar gangliocytomas that were immunopositive for GHRH. Tumour tissue persisted after debulking surgery and in the second case this was associated with persistent growth hormone hypersecretion, successfully suppressed by a somatostatin analogue.
Conclusions:
The development of functional pituitary adenomas in association with sellar gangliocytomas is poorly understood. We present a brief discussion of the possible aetiology of these unusual pituitary tumours.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss.
