DefinitionThis section has been translated automatically.

Acute, pruritic skin rash characterized by minute red papules and pustules, often occurring after exposure to heat (also in humid tropical climates). Miliaria rubra is caused by occlusion of the sweat gland duct in the epidermis ( stratum spinosum): Miliaria profunda (rarely observed in infants) is caused by occlusion of the dermal part of the sweat gland duct or at the transition to the epidermal papillae (stratum papillare). S.a.u. Anhidrosis, "thermogenic".

Occurrence/EpidemiologyThis section has been translated automatically.

Especially in the tropics and for people who work in warm and humid environments, for obese people with stress hyperhidrosis. Development within weeks and months after heat exposure. Also in infants after the first weeks of life (see below miliaria).

EtiopathogenesisThis section has been translated automatically.

Thermoregulatory problems due to sweat retention caused by:
  • Tropical heat, high humidity, swelling of the horny layer, secretion, escape of sweat into the interstitium, possible rupture of the excretory duct.
  • Bacterial toxins.
  • Metal salts, toxic detergents, strong ion flow in iontophoresis.
