Thanks for your query.
An epidermal cyst
is a benign growth that can occur in any area of the body lined by the epidermis
It is a firm, slow-growing lump underneath the skin. This cyst contains soft, cheesy-like skin secretions. These usually appear on the scalp
, face, neck, chest, upper back, genitals, or behind the ears.
It is generally caused by a blocked hair follicle.
There is nothing to worry about it, or anything further to do, as it has already been removed.
