The DRESS syndrome (drug rash with eosinophilia and systemic symptoms) is a serious pharmacodermia which must be taken into account when establishing an optimal early treatment to prevent a systemic and potentially lethal evolution.

Pharmacodermias are the third most frequent cause of adverse effects during surgical hospitalization, after nosocomial infections and intraoperative complications. In most cases, they pose a challenge to the surgeon, since their onset is nonspecific and, therefore, can be easily mistaken for a surgery complication.

We present the case of a 54-year-old man, healthy and without relevant background, who was operated on two times due to spontaneous abdominal bleeding. Three weeks after the last surgery, and coinciding with the administration of oral metamizole, the patient developed a DRESS syndrome. The initial unspecific deterioration, characteristic of this syndrome, is the main cause of the delay in diagnosis and correct treatment, causing the resulting evolution to systemic affectation.
