Miliaria Profunda
Overview
- Obstruction level: distal, dermal portion of the duct (at the dermo-epidermal junction).
- Clinical: pale, skin-coloured to whitish, firm 1–3 mm papules, no erythema, no pruritus, asymptomatic in appearance. Deeper obstruction → no visible vesiculation.
- Setting: typically after recurrent miliaria rubra in the tropics — travellers with prolonged tropical exposure / soldiers in desert climate.
- Complication: permanent anhidrosis in the affected area → thermoregulatory failure with tropical anhidrotic asthenia: heat intolerance, weakness, collapse, heat stroke risk.
