[Celiac crisis and acute tetany in pediatrics. Case report].

Celiac disease is an immune-mediated systemic disease with a wide spectrum of clinical presentations. The term celiac crisis describes the acute and potentially fatal form. Clinically it is characterized by severe diarrhea, dehydration, and metabolic disturbances. The case of a 7-year-old male patient attending the ward with tetany, lower limb edema, steatorrhea and weight loss of 8 months of evolution is reported, with analytical findings of hypocalcemia, hypomagnesemia, hypokalemia and coagulopathy. The diagnosis of celiac crisis was made on the basis of serological and clinical findings compatible with celiac disease in the context of severe metabolic abnormalities and acute malnutrition, later confirmed by pathological anatomy. The importance of this report lies in reviewing the characteristics of this serious entity, which requires a high index of suspicion for its diagnosis.
