Prickly Heat

I apologize for the irregularity of cases. Since taking my board exams, I have been swamped in our cardiac surgery ICU and this blog has been neglected. However, as the light at the end of the tunnel nears, we will get back on track with cases of the day on Mondays and Thursdays. Here's one to tide you over until next week. In fact, we found this rash on an ICU patient and consulted dermatology.


This benign rash is a common finding in newborns, especially in warm climates. Occasionally, the rash is associated with an inflammatory response, shown below.

Challenge: What's your diagnosis?

Prickly Heat

Miliaria is caused by accumulation of sweat beneath eccrine sweat glands that are obstructed by keratin. The first image shows miliaria crystallina, characterized by small thin-walled vesicles resembling dewdrops. The second image shows miliaria rubra, when obstructed sweat causes a local inflammatory response, resulting in groups of erythematous papules and pustules.
