Diffuse Miliaria Cristalina due to Severe Hypernatremic Dehydration: A Neonatal Case Report with a Current Literature Review

Miliaria is a common, transient cutaneous disease caused by obstruction of the eccrine sweat duct. A female patient who was admitted with the complaint of decreased sucking on the postnatal 15th day learned that after the postnatal 10th day, the sucking reflex decreased, the amount of urine decreased, and the number of stools per day decreased. We observed that the patient’s general condition was poor and that his weight loss was 31%. Fluid therapy was adjusted for the patient, whose serum sodium level was 192 mEq/L. On the 5th day, while the serum sodium level was 156 mEq/L and the body temperature was within normal limits, vesicles and bullae were detected in the body, especially in the trunk, and relatively few in the extremities. Although miliaria crystallina is a common skin problem in newborns, our case is the second documented case of miliaria crystallina due to hypernatremia in the literature. Physicians; It should be kept in mind that miliaria crystallina may be seen in the newborn during the treatment of severe hypernatremic dehydration.
