What is this an example of?
Pigmentation arising from paan chewing
What is Post inflammatory hyperpigmentation?
Where is this condition common?
Pigmentation which follows mucosal irritation and inflammation, during the healing phase with increased pigmentation
Common in chronic lichen planus in the buccal mucosa
