[The Herbst triad: finger clubbing, hypoproteinemia and iron deficiency anemia associated with gastroesophageal reflux]. / Tríada de Herbst: acropaquías, hipoproteinemia y anemia ferropénica, asociadas a reflujo gastroesofágico.

ABSTRACT

Gastroesophageal reflux with hiatal hernia has been associated with unusual presentations, including rumination syndrome, Sandifer syndrome (reflux esophagitis, iron deficiency anemia and head cocking) and the Herbst triad (iron deficiency anemia, hypoproteinemia and finger clubbing). We report a new case of this rare disease. Lack of awareness of gastroesophageal reflux as a possible cause of these striking symptoms could lead to complications and delayed surgery.
