[Boerhaave syndrome, as a cause of acute abdomen]. / Síndrome de Boerhaave, como causa de abdomen agudo.

Its clinical manifestations are such that an extensive differential diagnosis with other entities in necessary, but diagnostic delay worsens the prognosis. We present a new case of Boerhaave's syndrome, that debuted as a picture of acute abdomen which led to the realization of an exploratory laparotomy that failed to evidence the esophageal perforation.
