Lichen Planus

This 80 years old man referred to our outpatient clinic with erosive lesion on his lower lip and reticular lesion in his buccal membrane also

He goes under biopsy, and the clinical impression was: erosive lichen planus, AK and SCC

The histological findings of mucosal biopsy of the lesion, shows mucosal ulceration and lichenoid infiltration more in favor of erosive LP. Although possibility of actinic cheilitis can not ruled out
