Feocromocitoma - Overview

Nombres alternativos

Feocromocitomas; Paraganglionoma

Definición:

Es un raro tumor del tejido de la glándula suprarrenal que provoca la secreción de demasiada epinefrina y norepinefrina, hormonas que controlan la frecuencia cardíaca, el metabolismo y la presión arterial.

Causas, incidencia y factores de riesgo:

Un feocromocitoma puede presentarse como un tumor único o como más de una neoplasia y, por lo general, se desarrolla en la médula (centro o núcleo) de una o ambas glándulas suprarrenales. En raras ocasiones, este tipo de tumor se presenta por fuera de estas glándulas, usualmente en alguna otra parte del abdomen.

Muy pocos feocromocitomas son cancerosos.

Los tumores pueden presentarse a cualquier edad, pero son más comunes desde comienzos hasta la mitad de la adultez.
