instruction: hello doctor I have a birthmark behind the right side of my neck which looks like a black thick mass I had once consulted a skin specialist to check if there are any options to get this removed I was told that even if it is removed by surgical means there are chances that it may reappear I want to confirm this do we have any options to remove it by surgical or nonsurgical means are there laser treatments available will I have to remove my hair if I need to undergo treatment I have attached a photograph of the affected area
output: hi I have seen the photo I understand your concern the condition is known as nexus sebaceous in case of deep surgical excision in nexus sebaceous chances of it coming back are very less the thing is the excision should be deep to minimize the chances of recurrence laser treatments are there but not very effective and chances of recurrence are more hair needs to be removed as the area should be devoid of it to perform surgery cost depends on the different doctors and their location or specialty
