Abstract
CONTEXT: Pheochromocytomas and paragangliomas (PHEO/PGL) are neuroendocrine tumors that arise from sympathetic and parasympathetic paraganglia. Diagnosed rarely during childhood, PHEO/PGL are nonetheless important clinical entities, particularly given our evolving understanding of their pathophysiology. EVIDENCE ACQUISITION: We identified articles through the U.S. National Library of Medicine by using the search terms pheochromocytoma and paraganglioma. Results were narrowed to manuscripts that included children and studies related to the genetics of PHEO/PGL. Web-based resources for genetic disorders were also used. For all articles, we performed subsequent reference searches and verification of source data. EVIDENCE SYNTHESIS: Up to 20% of PHEO/PGL are diagnosed in children. Most are functional tumors, and clinical presentation includes symptoms related to catecholamine hypersecretion and/or tumor mass effect. Increasingly, PHEO/PGL are identified during presymptomatic screening in children with genetic syndromes associated with PHEO/PGL (multiple endocrine neoplasia type 2, von Hippel-Lindau disease, and the paraganglioma syndromes). Plasma and/or urine metanephrines are the best diagnostic test for a functional tumor, and the management of pediatric patients is similar to adults. Genetic counseling should be undertaken in all cases. Although most pediatric PHEO/PGL are benign, these tumors can occasionally metastasize, a condition for which no curative treatment exists.
CONCLUSIONS: Although PHEO/PGL are rarely diagnosed during childhood, the pediatric provider should be able to recognize and screen for such tumors, particularly in the context of a known genetic predisposition. Optimal care of these children includes a multidisciplinary team approach at centers experienced in the evaluation and treatment of these uncommon yet fascinating endocrine neoplasms.

Abstract
Pheochromocytomas are rare catecholamine-secreting tumors that arise from chromaffin tissue within the adrenal medulla and extra-adrenal sites. Because of the excess secretion of hormones, these tumors often cause debilitating symptoms and a poor quality of life. While medical management plays a significant role in the treatment of pheochromocytoma patients, surgical excision remains the only cure. Improved medical management and surgical techniques and an increased understanding of hereditary disease have improved the outcome of pheochromocytoma patients with benign disease; however, the outcome of patients with malignant disease remains poor. In this review, we discuss the presentation, diagnosis, management, and future directions in the management of this disease.
Manejo anestésico de feocromocitoma: reporte de un caso

El manejo anestésico del paciente con feocromocitoma es un reto para el Anestesiólogo y su equipo quirúrgico. Nuestro objetivo es evitar la mortalidad trans y postoperatoria. Este padecimiento implica amplios conocimientos acerca de esta patología que afortunadamente es poco frecuente. Consideramos que es de vital importancia la comunicación entre el Cirujano, Cardiólogo, Enfermera, Laboratorio y Anestesiólogo, así como la visita preoperatoria es menester infundirle confianza al paciente dado el difícil manejo a que va a ser sometido por todo el equipo quirúrgico. Incluye tratamiento a base de alfa y betabloqueadores 2 a 3 semanas antes de su ingreso a quirófano, el cual debe ser en óptimas condiciones. Podemos concluir que la anestesia mixta con bloqueo epidural más anestesia general es una buena alternativa de manejo. El bloqueo epidural proporciona disminución de la descarga adrenérgica y disminución en el consumo de narcóticos, halogenados y relajantes musculares, además de proporcionar analgesia postoperatoria. Siempre debemos estar atentos y preparados con medicamentos para cualquier contingencia.
Palabras clave: Feocromocitoma, bloqueo epidural, anestesia mixta.

Introducción
Los feocromocitomas son tumores poco frecuentes, derivados del sistema APUD, y
habitualmente benignos que sintetizan, almacenan y liberan catecolaminas.. Ocurre
solamente en el 0,5 - 0,1% de la población hipertensa, pero constituye una causa tratable
de HTA.
