Synopsis

Miliaria is caused by occlusion of the eccrine sweat ducts. There are various clinical patterns of miliaria depending on the level of occlusion.

Miliaria crystallina results from blockage of the eccrine sweat duct in the stratum corneum, corresponding to the formation of asymptomatic pinpoint, fragile vesicles. Miliaria crystallina is most common in neonates, but is seen in adults in the setting of bedridden patients with high fever and excessive sweating. The use of occlusive products prior to exercise may induce this as well. It is also more common in tropical climates.

When the occlusion of the sweat duct is deeper in the epidermis, miliaria rubra (prickly heat), miliaria pustulosa, or miliaria profunda may result.
