Clinical utility of dermoscopy on diagnosing pigmented papillary
fungiform papillae of the tongue: A systematic review
Abstract
Importance: The practice of dermoscopy in dental and oral examination is
low due to less popularity and not well established of the diagnostic
tool in dental practice. The dermoscopy examination provides a specific
dermoscopes details for pigmented papillary fungiform of tongue (PFTT)
as cobblestone appearance and rose-petal appearance. With this
dermoscopes details serves as a non-invasive diagnostic tool and
prevents biopsy procedure. Objective: We performed a systematic review
to evaluate the published papers related to pigmented papillary
fungiform on the tongue, aiming to understand the diagnostic role of
dermoscopy examination in pigmented papillary fungiform. Evidence
review: A PubMed, Google scholar and Embase databases were searched for
the PFTT studies and case reports published during the period 1974-2020.
Initial result was 136 studies. Final exclusion of 27 articles was made
based on the following factors: reports with no clinical images, studies
that did not confirm the diagnosis of PPFT and studies that did not use
the dermoscopes details. Finally, seventeen studies with nineteen cases,
reported of pigmented papillary fungiform of the tongue. Finding: The
diagnosis of tongue papillary fungiform can be determined by dermoscopy
examination. Six studies (consist six cases) reported the dermoscopy and
histopathology diagnosis of pigmented papillary fungiform, eleven
studies (consist thirteen cases) reported only the dermoscopy. The
dermoscopy examination presented cobblestone appearance is 47.37% and
rose petal appearance is 52.63%. The comparation study by
histopathology diagnosis was done, revealed no specific appearances.
Conclusions and relevance: The clinical appearance and dermoscopy is the
key for diagnosis of the papillary fungiform on the tongue. Further
research is needed for determining the etiology and predisposing factor
in papillary fungiform so that the possibility of developing this
condition can be predicted and proper treatment could be performed.
