ICD-10: L74.2

Miliaria profunda, classified under ICD-10 code L74.2, is a type of eccrine sweat disorder characterized by the obstruction of sweat glands, leading to specific clinical presentations and symptoms. Understanding its clinical features, signs, symptoms, and patient characteristics is essential for accurate diagnosis and management.

Clinical Presentation

Miliaria profunda typically occurs in response to heat and humidity, often affecting individuals in hot climates or those engaged in strenuous physical activities. The condition is most commonly seen in infants and young children but can also affect adults, particularly those with excessive sweating or occlusive clothing.

Signs and Symptoms

1. Skin Lesions:
   - The hallmark of miliaria profunda is the appearance of skin lesions that may present as small, flesh-colored or slightly red papules. These lesions can be found on areas of the body that are prone to sweating, such as the trunk, neck, and groin.
   - Unlike miliaria rubra, which presents with vesicles and is more superficial, miliaria profunda lesions are deeper and may not be as easily visible on the surface.

2. Pruritus:
   - Patients often experience itching or discomfort in the affected areas, which can lead to scratching and secondary infections if not managed properly.

3. Heat Sensitivity:
   - Individuals may report increased discomfort in hot environments, as the condition exacerbates with heat exposure.

4. Inflammation:
   - In some cases, the lesions may become inflamed, leading to erythema (redness) and swelling around the affected areas.

Patient Characteristics

• Age: Miliaria profunda is more prevalent in infants and young children due to their immature sweat glands. However, adults, especially those with hyperhidrosis or who wear tight clothing, can also be affected.
• Environmental Factors: Patients living in tropical or subtropical climates, or those who frequently engage in activities that induce sweating, are at higher risk.
• Underlying Conditions: Individuals with conditions that impair sweating or those who are bedridden may also be more susceptible to developing miliaria profunda.
• Lifestyle Factors: Occupations that involve physical labor or sports, as well as the use of occlusive clothing, can contribute to the development of this condition.
