Miliaria crystallina

Clin Exp Dermatol. 2023 Apr 27;48(5):462-467. doi: 10.1093/ced/llad032.


Miliaria crystallina (MC) is an uncommon form of a sweat retention syndrome that chiefly affects neonates. It is more common in hot and humid conditions, such as in tropical regions. It commonly presents as clusters of dewdrop-like vesicles on a nonerythematous base that heals with furfuraceous scaling. A clinical diagnosis is often sufficient. The differential diagnosis is wide and varying. One of the hallmarks of MC is its self-limiting nature. The purpose of this review is to increase awareness of this condition among physicians and dermatologists.
