Sebaceous gland cyst, also known as powder tumor, refers to the cyst formed by sebaceous gland accumulation after sebaceous gland duct obstruction. This is the most common benign tumor of the skin, located in the skin, with a complete capsule (capsule wall), which stores tofu-like secretions and is accompanied by odor. It occurs in scalp, face, behind ears and other parts. Growth is slow and asymptomatic, and there may be redness, swelling and pain when complicated with infection.

Surgery is the only treatment for sebaceous cyst. Special care should be taken during surgical separation, because the capsule wall is very thin and should be taken out as completely as possible. If the cyst wall remains, it is easy to relapse.

When the capsule wall of the powder tumor is not completely removed, the residual capsule wall can still secrete bean curd residue-like substances, forming the recurrence of the powder tumor. Recurrent sebaceous cyst can still be surgically removed, and the capsule should be completely removed to avoid recurrence.

It didn't take long for you to grow taller after the operation. This is the manifestation of cyst recurrence. It is suggested that the cyst should be removed again when there is no inflammation, and it is best to completely remove the wall of the powder tumor to avoid recurrence.
