I mean excision for it if the pt. Is severely symptomatic.. but antibiotics nd analgesics with cleaning nd drying the ear carefully would be enough.. but in case of large size or severe symptoms surgical excision under General aenethesia would be the definitive treatment
It might be choleostoma.. the pic nt clear enough.. but didn't take a biopsy!!
Why you say it is colestatoma? I can't diagnosis at all!
