A male patient aged 20 years, who presents with a well-demarcated reddish area of depapillation on the dorsum of tongue near the midline. It was located 1 cm anterior to the circumvallate papillae and was roughly diamond shaped. Its surface was smooth, raised and fissured; the opposing palatal mucosa was non-erythematous (kissing lesion was absent). History revealed that it was stable since childhood and was occasionally associated with burning sensation.
The patient was otherwise healthy, with no history of tobacco usage or diabetes. The patient was given fluconazole (50mg, 1 time/day for 14 days) to rule out candidiasis, but, the lesion did not regress. What is your diagnosis? *This case is from Docplexus Editorial Team for educative purpose only
