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. The 3 main types of miliaria—crystallina, rubra, and profunda—are classified based on the depth of sweat duct obstruction, each presenting with distinct clinical and histological features. 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. The rash is typically self-limiting and usually resolves without treatment. The primary cause of miliaria is the obstruction of eccrine sweat glands or ducts, resulting from cutaneous debris or bacteria, such as Staphylococcus epidermidis, which forms biofilms. This obstruction causes sweat to leak into the epidermis or dermis, leading to cellular overhydration, swelling, and further duct occlusion. In more severe cases, deeper involvement of the eccrine glands or ducts can result in their rupture. 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. This activity covers the epidemiology, genetics, clinical presentation, and management of miliaria, emphasizing the importance of an interprofessional healthcare team in providing comprehensive treatment and prevention strategies tailored to individual patient needs.
