Background: Pigmented fungiform papillae of the tongue (PFPT) is a rare benign pigmen- tary disorder of the tongue. In dark-skinned individuals, PFPT appears to be relatively com- mon. However, limited data exist on PFPT in Korean patients.
Objective: We aimed to investigate the clinical characteristics of PFPT in Korean patients.
Methods: Patients diagnosed with PFPT between 1995 and 2021 at the Pusan National Uni- versity Hospital were included. Clinical characteristics of PFPT, dermoscopic findings, and comorbidities were reviewed.
Results: A total of 19 patients diagnosed with PFPT were enrolled. The male to female ratio was approximately 1:5. The mean age at diagnosis was 41.1 years (range, 8~67 years). Ac- cording to Holzwanger’s classification, Type I was the most common (89.5%). PFPT was commonly concomitant with pigmentary disorders, including mucosal melanotic macules, Laugier-Hunziker syndrome, melasma, and melanonychia (6/19, 31.6%). Preceding oral in- fection or inf lammatory lesions were found in four patients (21.1%), and systemic diseases and infectious diseases existed in two patients (10.5%). Dermoscopic examination was per- formed in seven patients; pigmented border with dichotomized vessels (rose petal pattern, 71.4%) and diffuse pigmentation (cobblestone pattern, 71.4%) were common findings.
Conclusion: Our study shows PFPT can coexist with pigmentary disorders. Concomitant pigmentary disorder shows an association with sex hormone or susceptibility to abnormal pigmentation may be a possible cause of PFPT.
