Causes of Eruptive Vellus Hair Cyst

The exact cause of these cysts is not fully understood, but they are believed to arise from abnormalities in the hair follicles. Factors such as genetic predisposition, hormonal imbalances, and inflammation in the hair follicles may contribute to the development of eruptive vellus hair cysts. While these cysts are generally harmless and do not require treatment, individuals with concerns about their skin should consult a dermatologist for evaluation and management.

Genetics play a significant role in the development of eruptive vellus hair cysts, with inherited factors contributing to their formation.
Hormonal imbalances, such as those seen in conditions like polycystic ovarian syndrome, can lead to the appearance of eruptive vellus hair cysts.

Skin trauma or injury, such as from repeated friction or pressure on the skin, may trigger the formation of eruptive vellus hair cysts.

Types of Eruptive Vellus Hair Cyst

They can be classified into two main types based on their appearance and characteristics: Type 1 cysts present as small, dome-shaped papules with a central pore, while Type 2 cysts are larger and often have a darker color due to the presence of trapped sebum.
