What is Eruptive vellus hair cyst and explain in detail?
Eruptive vellus hair cysts (or EVHC) are small lesions that occur most often in the chest wall, abdomen and extremities, often with a crusted surface.: 680  EVHC may occur randomly, or it can be inherited as an autosomal dominant trait. The condition affects males and females equally, and sporadic cases usually appear at 4–18 years of age. The cysts appear similar clinically to steatocystoma multiplex, as well as acneiform eruptions and milia. Therapeutic techniques that are safe and effective are rare, with incision and drainage being the primary form of treatment when sporadic regression does not occur
