A 65 yr old female non DM non HTN with no known addictions, came to me with h/o painful ulcerations over the tongue,soft palate and buccal mucosa since 1yr...on and off...she received multiple treatments...including multivitamins, short courses of steroids twice in this one year..subsided in between.But this time she is having it since 1 month,not subsiding with treatment and severe pain along with difficulty in swallowing. I diagnosed it as recurrent aphthous stomatitis and adv workup. HIV negative,RBS normal,UGI endoscopy-Normal.ANA sent report awaited. There are no other signs and symptoms suggestive of malignancy or autoimmune or behcets disease. I suspected HSV stomatitis and so started her on acyclovir, but did not send tzanck smear...also put her on triamcinolone 0.1% buccal paste, amlexanox and lignocaine ointment and also started pentoxyfylline 400 tid...she came after 3 days with no improvement and so i added defcort 6 mg bid. what is the next course of action,should i get a biopsy.
