Topical treatments that have been advocated involve lotions containing calamine, boric acid, or menthol; cool, wet-to-dry compresses; frequent showering with soap (although some discourage excessive use of soap); topical corticosteroids; and topical antibiotics. The topical application of anhydrous lanolin and isotretinoin has resulted in dramatic improvement in patients with miliaria profunda.

Miliaria crystallina and miliaria rubra can occur in persons of any age, but the diseases are most common in infants. Miliaria profunda is more common in adults than in infants and children.

Miliaria profunda occurs in individuals who usually live in a tropical climate and have had repeated episodes of miliaria rubra. Lesions develop within minutes or hours after the stimulation of sweating and resolve quickly, usually in less than an hour after the stimulus is removed. The lesions are asymptomatic. The lesions associated with miliaria rubra cause intense pruritus and stinging that is exacerbated by fever, heat, or exertion.

In miliaria crystallina, cytologic examination of the vesicular contents fails to reveal inflammatory cells or multinucleated giant cells (as would be expected in herpes vesicles).
