ABSTRACT

Los feocromocitomas son tumores que proceden de las células cromafines del sistema nervioso simpático y actúan sintetizando y liberando catecolaminas. Suelen presentarse entre la cuarta y quinta década de la vida y tienen presentaciones clínicas muy diversas. Ocurren solamente en 0.1-0.2% de la población hipertensa, constituyen una causa tratable y curable de hipertensión arterial, así como de otras manifestaciones derivadas de la liberación incontrolada de catecolaminas. La isquemia arterial periférica secundaria a la liberación masiva de aminas por un feocromocitoma es muy infrecuente. Aquí se presenta un caso clínico de feocromocitoma manifestado como síndrome del dedo azul en un paciente con pulsos distales conservados y el antecedente de mal control tensional a pesar de tratamiento con dos fármacos.


Pheochromocytomas are tumors that arise from chromaffin cells of the sympathetic nervous system and act by synthesizing and releasing catecholamines. They usually occur between the fourth and fifth decade of life and have a very wide clinical presentation. They occur only in 0.1-0.2% of the hypertensive population and represent a treatable and curable cause of arterial hypertension, as well as other symptoms derived from the uncontrolled secretion of catecholamines. Peripheral arterial ischemia secondary to massive amines release by a pheochromocytoma is a very uncommon condition. Here we report a case of pheochromocytoma manifested as blue finger syndrome in a patient with palpable distal pulses and history of poor blood pressure control despite treatment with two drugs.
