[Widespread miliaria crystallina: about a case].

Area of Science:

• Dermatology
• Internal Medicine

Background:

• Prickly heat (miliaria) results from sweat duct obstruction.
• It manifests differently based on obstruction depth: superficial (crystallina), mid-epidermal (rubra), or deeper (profunda).

Observation:

• A 70-year-old diabetic female in intensive care presented with diffuse, firm, clear vesicular lesions.
• These lesions suggested miliaria crystallina, a form of prickly heat.

Findings:

• Miliaria crystallina is linked to sweat retention from stratum corneum obstruction.
• The patient's condition resolved spontaneously with fever regression.

Implications:

• This case illustrates a typical presentation and benign course of miliaria crystallina.
• Understanding sweat duct obstruction levels aids in diagnosing various miliaria types.
