Subcutaneous cysts that are not removed may cause skin infections, bulges, lesions, hard nodules under the skin, and very rarely, transformation into skin cancer. The severity of symptoms varies from person to person.
Subcutaneous cysts are cystic lesions in which a cystic luminal structure contains fluid or cellular components, usually located in the dermis or deeper. The cause is related to the inability of sebaceous glands to drain, localized skin damage, and genetics.
If left untreated, rupture of a dermal cyst may lead to secondary infection, with redness, swelling, pain, and pus draining from the skin at the site of the rupture.
Epidermal cysts can occur anywhere on the body and form removable subcutaneous nodules.
Localized swellings located in the dermis or deeper may be elevated above the surface of the skin, cystic to the touch, and vary in size.
In rare cases, skin cysts may turn into skin cancer. Skin cancers are of different types with different manifestations, but most of them progress rapidly.
If you find subcutaneous cysts, you should actively seek medical treatment under doctor’s guidance without delay, so as not to delay the condition and lead to adverse consequences. Skin hygiene should be paid attention to in life to prevent secondary infection.
