Congenital miliaria crystallina - A diagnostic dilemma.

Miliaria crystallina is a transient, superficial obstruction of eccrine sweat ducts resulting in rapidly evolving noninflammatory vesicles. The disease is observed frequently in hot, humid, tropical climates and in the neonatal period, most likely due to lack of maturation of the sweat duct during the first few days following birth. It is rarely present at delivery and remains a diagnostic dilemma for the neonatologists. We report a rare case of "Congenital miliaria crystallina" that was present at birth.
