Hi, i am 35 years old ( not married) have a itchless , painless, round purple mark surrounded by a white line in my penis skin near the rim.
My dermatologist says it could be psoriasis or lichen planus. But before going for a biopsy he wants to treat it as a fungal infection so he put me on onabet (sertaconazole nitrate) ointment and Tab forcon 150. The medication started 10 days before but i am not seeing any changes in the mark.Should i have to continue the medication for 4 weeks as prescribed to get the results. Am i on the right track of treatment. Will this be serious disease . I am worried because of getting married in march . Please advice . thanks
