Background
- Pruritic, maculopapular, erythematous rash over normally clothed areas of body
Pathophysiology
- Acute inflammation of sweat ducts caused by blockage of pores by macerated skin
- Ducts become dilated under pressure and ultimately rupture
- This produces superficial vesicles in malpighian layer of skin on a red base
- May progress to miliaria profunda (white papules) if duct ruptures a second time
- This produces superficial vesicles in malpighian layer of skin on a red base
- Ducts become dilated under pressure and ultimately rupture
Differential Diagnosis
Environmental heat diagnoses
Treatment
- Antihistamines
- Dicloxacillin or erythromycin if appears superinfected
