Pigmented fungiform papillae (PFP) is a benign anatomical variant resulting from increased melanin production within the fungiform papillae of the tongue. PFP typically appears in childhood or adolescence and persists throughout life without progression. PFPs are benign and do not require treatment.

PFP is more common in individuals with darker skin colors. The prevalence ranges from 1%-3% in the general population, with a prevalence of up to 30% observed among Black women. Females are more commonly affected, with some studies reporting a female-to-male ratio of 5:1.
