Doctor Nguyen Thanh Son Vu, a specialist in pediatric surgery at Tam Anh General Hospital, Ho Chi Minh City, explained that Thuy's epidermal cyst on her right temple was about 1 cm in size. The cyst had repeatedly inflamed, necessitating surgical removal.

An epidermal cyst is a subcutaneous sac filled with keratin. These cysts typically grow slowly and can persist for extended periods. Initially, they are often painless and present no clear symptoms. However, if a cyst becomes inflamed or ruptures, the surrounding skin can swell, redden, and cause discomfort.

Doctor Vu emphasized that while medication can alleviate inflammation when a cyst is swollen and red, it does not fully remove the cyst. The underlying mass can continue to enlarge or re-inflame, often leading to misidentification as a common pimple.

Doctor Vu noted that while most epidermal cysts are benign, they can enlarge and become a cosmetic concern if left untreated. He advised parents against attempting to squeeze, prick, or press any unusual skin growths on their children. If a child develops a persistent, growing, swollen, red, or painful subcutaneous bump, or experiences repeated inflammation, parents should seek medical evaluation to determine the cause and appropriate treatment.
