  • 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

Differential Diagnosis
