Diagnosis: Miliaria profunda.
MICROSCOPIC FINDINGS AND CLINICAL COURSE
The histologic sections showed focal lymphocytic inflammation around the insertion of the eccrine duct into the epidermis. There was slight alteration, with minimal spongiosis, focal perieccrine inflammation, and a somewhat distorted eccentric eccrine duct. The findings were suggestive of mild chronic miliaria profunda.
We recommended that our patient avoid strenuous exercise for several months. Because he played on his high school basketball team, he thought avoidance of exercise was impossible. We recommended application of anhydrous lanolin before exercise, which led to improvement.
DISCUSSION
Miliaria is caused by blockage of the flow of sweat from the eccrine duct to the skin surface, with subsequent rupture of the duct and leakage of sweat into different levels of the skin. Classification of the type of miliaria is based on the level of eccrine ductal obstruction. The 3 types of miliaria are miliaria crystallina (obstruction at the stratum corneum), miliaria rubra (obstruction at the stratum . . . [Full Text of this Article]
