Apocrine miliaria, also known as prickly heat or sweat rash, is a common skin condition that occurs due to the blockage of sweat ducts. It is characterized by the development of small, itchy, red bumps or blisters on the skin, typically in areas where sweat glands are concentrated, such as the armpits, groin, or under the breasts.
The condition is named after the apocrine sweat glands, which are responsible for producing a thick, milky sweat that contains proteins and lipids. When these sweat glands become blocked, often due to factors like excessive sweating, high humidity, or tight clothing that traps sweat against the skin, it leads to the formation of apocrine miliaria.
Apocrine miliaria is more common in warm and humid climates, as well as in individuals with a tendency to sweat excessively. It can also occur in infants, as their sweat glands are not fully developed. The symptoms typically include a prickling or stinging sensation, redness, and the appearance of small bumps that may be filled with fluid. In some cases, the affected area may also become inflamed or infected, leading to additional discomfort.
Treatment for apocrine miliaria often involves keeping the affected area cool and dry, wearing loose-fitting clothing, avoiding excessive sweating, and using mild soaps and powders. Over-the-counter hydrocortisone creams or antihistamines may be recommended to alleviate itching. In severe cases, prescription medications or topical creams may be prescribed by a dermatologist.
Overall, apocrine miliaria is a common and generally harmless skin condition that can cause discomfort and itchiness. With proper care and management, symptoms can usually be relieved, and the condition typically resolves on its own within a few days or weeks
