Lesions are firm, flesh-colored, nonfollicular papules that are 1-3 mm in diameter.

Lesions occur primarily on the trunk, but they can also appear on the extremities.

Lesions are transiently present after exertion or other stimulus that results in sweating.

Affected skin shows diminished or absent sweating.

In severe cases that lead to heat exhaustion, hyperpyrexia and tachycardia may be observed.

A rare giant centrifugal variant of miliaria profunda has been reported in young infants (of about age 3 mo) who presented with multiple erythematous lichenoid papules that coalesced to form infiltrated annulare and geographic plaques 1-5 cm in size with an erythematous border, located over the trunk and extensor extremities.
