  https://www.ncbi.nlm.nih.gov/sites/books/NBK537176/

  Miliaria, also known as eccrine miliaria, is a common skin condition caused by the blockage of eccrine sweat glands and ducts. This obstruction leads to the backflow of eccrine sweat into the dermis or epidermis, resulting in a rash characterized by sweat-filled vesicles under the skin. […] Miliaria is often referred to as „heat rash,” „prickly heat,” or „sweat rash,” and is most prevalent in warm, humid climates, especially during the summer. […] Management focuses on reducing sweating and preventing duct blockage through measures such as staying in cooler environments, wearing breathable clothing, and removing skin-occluding items. Dermoscopy and, in uncertain cases, a skin punch biopsy can assist in diagnosis, with high-definition optical coherence tomography helping to identify duct obstructions.

• #2 Miliaria – Wikipedia

  https://en.wikipedia.org/wiki/Miliaria

  Miliaria, commonly known as heat rash, sweat rash, or prickly heat, is a skin disease marked by small, itchy rashes due to sweat trapped under the skin by clogged sweat-gland ducts. Miliaria is a common ailment in hot and humid conditions, such as in the tropics and during the summer. Although it affects people of all ages, it is especially common in children and infants due to their underdeveloped sweat glands. […] Symptoms of miliaria include small, red rashes, called papules, which are irritated and itchy. These may simultaneously occur at a number of areas on a patient’s body, the most common including the upper chest, neck, elbow creases, under the breasts, and under the scrotum. […] The most commonly encountered form of the illness is miliaria rubra, in which obstruction causes leakage of sweat into the deeper layers of the epidermis, provoking a local inflammatory reaction and giving rise to the typical appearance of redness (hence rubra) and larger (but still only a few millimetres), blister-like lesions. This form of the illness is often accompanied by the typical symptomsintense itching or „pins and needles” with a lack of sweating (anhidrosis) to affected areas. […] Medical assistance should be sought for the first episode of a rash with the appearance of miliaria. The differential diagnosis includes several conditions that an experienced practitioner should be able to recognise and may require treatment distinct from the usual measures taken for miliaria.

  Miliaria is primarily diagnosed clinically, as laboratory tests are often inconclusive and generally not useful. Dermoscopy is a valuable tool, particularly for individuals with darker skin, as it can reveal large white globules with surrounding darker halos (white bullseye). If the diagnosis remains uncertain, a skin punch biopsy may be helpful. High-definition optical coherence tomography can also assist in identifying the obstruction of the eccrine duct.

  https://en.wikipedia.org/wiki/Miliaria

  Miliaria, commonly known as heat rash, sweat rash, or prickly heat, is a skin disease marked by small, itchy rashes due to sweat trapped under the skin by clogged sweat-gland ducts. Miliaria is a common ailment in hot and humid conditions, such as in the tropics and during the summer. Although it affects people of all ages, it is especially common in children and infants due to their underdeveloped sweat glands. […] Symptoms of miliaria include small, red rashes, called papules, which are irritated and itchy. These may simultaneously occur at a number of areas on a patient’s body, the most common including the upper chest, neck, elbow creases, under the breasts, and under the scrotum. […] The most commonly encountered form of the illness is miliaria rubra, in which obstruction causes leakage of sweat into the deeper layers of the epidermis, provoking a local inflammatory reaction and giving rise to the typical appearance of redness (hence rubra) and larger (but still only a few millimetres), blister-like lesions. This form of the illness is often accompanied by the typical symptomsintense itching or „pins and needles” with a lack of sweating (anhidrosis) to affected areas. […] Medical assistance should be sought for the first episode of a rash with the appearance of miliaria. The differential diagnosis includes several conditions that an experienced practitioner should be able to recognise and may require treatment distinct from the usual measures taken for miliaria.
