How are cysts formed? You have to know these causes

Cysts are a type of benign tumor and generally do not cause much harm to the human body. However, we need to understand in advance how cysts are formed.

A congenital hereditary

1. Pilothecosis: In the past, 114 degrees of sebaceous cysts were autosomal dominant.

2. Multiple steatocystoma: autosomal dominant inheritance.

3. Dermoid cyst: It is congenital and present at birth.

4. Bronchogenic and thyrohyoid duct cysts are caused by congenital developmental abnormalities.

5. Midline penile cyst is caused by congenital developmental abnormality.

6. The etiology of eruptive ankylosing follicles is unclear, and some reports suggest that it is an autosomal dominant inheritance.

Second, the cause is unknown

1. New fluid-filled cyst.

2. Milia: The primary type has unknown causes, while the secondary type is often seen in epidermal hyperplasia, congenital ectodermal defect, delayed dermatophytosis and after skin grinding.

3. Epidermal cyst: the cause is unknown.
