Paraganglioma is a rare tumour arising from the paraganglion. A paraganglioma arising in the adrenal gland is known as a pheochromocytoma.
General
- Definition: tumour of paraganglion.
- Can be sympathetic or parasympathetic.
- Locations of paraganglia
- Paravertebral (retroperitoneal)
- Near the large blood vessels of the head and neck and base of skull
- Scattered in other tissues
- Most common paraganglioma = pheochromocytoma.[1]
- Sites relate to locations of paraganglia
- Head & neck most common - neck, ear, carotid body, base of skull
- Retroperitoneal/abdomen
- Bladder
- Sites relate to locations of paraganglia
Special site names
- Carotid body tumour = paraganglioma of carotid body - very vascular - right near a major artery. Don't stick a needle in it.
- Glomus tympanicum tumor = paraganglioma of the middle ear - pulsitile tintinitis and conductive hearing loss.
- Pheochromocytoma - basically a 'paraganglioma' in the adrenal medulla
Epidemiology
- Rare.
- Rarely malignant.
Familial syndromes associated with paragangliomas:[2]
- von Hippel Lindau.
- Hereditary paragangliomatosis.
- Neurofibromatosis type 1 (von Recklinghausen disease).
- MEN 2A.
- MEN 2B.
- Carney-Stratakis syndrome - GISTs and paraganglioma.[3]
- SDH mutation associated (SDHB, SDHC and SDHD).[4]
Other associations - not proven to be genetic:
Clinical
- 10% bilateral, multiple, familial, pediatric and malignant.[5]
- Not quite true... more than 10% are familial - see pheochromocytoma article.
Gross
- Dusky colour.
Note:
- Pheo (in pheochromocytoma) is dusky; chromo is colour.
Image:
Microscopic
Features:[6]
- Zellballen - nests of cells - key low power feature.
- Zellballen is "cell balls" in German.
- Fibrovascular septae and sustentacular cells (structural support cell).
- Finely granular cytoplasm (salt-and-pepper nuclei).
- +/-Hemorrhage - very common.
DDx:
- Neuroendocrine tumour - nests surrounded by stroma/do not touch.
- Pheochromocytoma - paraganglioma of the adrenal gland.
- Gangliocytic paraganglioma - has schwannian component and ganglion cells, usu. duodenum.
