[Pheochromocytoma. A case report]
Abstract:
We present the case of a 34 year-old male, who was diagnosed with a malign pheochromocytoma and who was treated with left laparascopic suprarenalectomy. This is a neoplasia of the chromoffin cells with a prevalence of two cases per million inhabitants, which generally causes the typical symptoms of episodic freeing of catecholamines. We describe the case's form of presentation, which began with successive episodes of intense abdominal pain on the left side. In the abdominal pelvic ultrasound and abdominal CT, a mass of 6.5 cm diameter was objectified, dependent on the left suprarenal gland. High levels of metanefrines and catecholamines were evident in the urine. A total left laparoscopic adrenalectomy was carried out. The pathological anatomy showed malign pheochromocytoma.

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. Congenital adrenal hyperplasia, a genetic ailment causing...

Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...
