Phaechromocytoma with Histopathologic Aspects
نویسندگان
چکیده
Phaeochromocytoma is a term used for catecholamine secreting tumors that arise from chromaffin cells of sympathetic paraganglia. The new World Health Organisation (WHO) classification of endocrine tumors has recommended to reserve the term phaeochromocytoma for intraadrenal tumors only and the others are defined as sympathetic or parasympathetic paragangliomas, further categorised by site. Although it was the first adrenal tumor to be recognised, the term phaeochromocytoma was introduced many years later by Pick in 1912. The name is based on the fact that the tumors get dark brown after exposure to potassium dichromate because of chromaffin reaction.
