How long do these cysts last? What do they look like and how can you tell if it is one? Thanks a bunch!
Hello,
The painless lump that you are having seems like a sebaceous cyst. A sebaceous cyst is a closed sac occurring just under the skin which contains a "pasty" or "cheesy" looking substance called keratin.They may occur anywhere on body but scalp, ears, back, face, and upper arm, are common sites for sebaceous cysts. Blocked sebaceous glands, swollen hair follicles and excessive testosterone production will cause such cysts.
Generally no treatment is required but they become painful then it means they are infected,Then surgical excision by traditional wide excision, minimal excision, and punch biopsy excision may be required.
The other possibility is of swollen lymph node.It may be due to some recent infection.
Hope it helps.Take care and pls do kee me posted in case you want any more clarification.Kind regards.
