Dermatology/red bump on arm
I have a red bump on my forarm which has been there for a few months now, thought it would go away but its not. Just wondering what it is and how to get rid of it. Thank you
The diagnosis of this type of bump would be done by a biopsy and then sent to a Dermpath lab for a diagnosis. This type of lesion could be a cyst, an infection causes by bacteria or virus or fungus, the lesion could be a dermatofibroma which is a type of scar tissue. The only way to know for sure is with a biopsy.
