Diagnosis is clinical, and, in cases of whitish plaques, it may be difficult to differentiate between oral hairy leukoplakia, potentially malignant leukoplakia or squamous cell carcinoma. Thus, widefield optical fluorescence complementary examination may allow a better visualization of the local hairlike pattern of hyperkeratinization, typical of the hairy tongue, facilitating the diagnosis. In this work, a 57-year-old man was referred to the Dental Specialties Department of the Divin\u00f3polis Health Department (MG, Brazil) by a general dental practitioner, aiming a differential diagnosis of possible malignant lesion on the dorsal tongue surface. The complementary examination by wide-field optical fluorescence was performed. For this, it was employed a device with high-power light-emitting diode emitting light centered at a wavelength of (400\u00b110) nm and maximum irradiance of (0.040\u00b10.008) W\/cm2 was used for fluorescence visualization. Fluorescence images showed projections of hairlike appearance in tongue dorsal surface with no aspects of malignancy. Hairlike appearance is the principal feature of hairy tongue. In this way, the final diagnosis was established. In conclusion, in this case, the use of widefield optical fluorescence in oral diagnostic routine provided a differential diagnosis, with no need of an incisional biopsy.<\/jats:p>","DOI":"10.1590\/0103-6440201902270","type":"journal-article","created":{"date-parts":[[2019,4,6]],"date-time":"2019-04-06T16:33:04Z","timestamp":1554568384000},"page":"191-196","source":"Crossref","is-referenced-by-count":6,"title":["Hairy Tongue: Differential Diagnosis by Use of Widefield Optical Fluorescence"],"prefix":"10.1590","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1817-3025","authenticated-orcid":false,"given":"S\u00e9rgio Ara\u00fajo","family":"Andrade","sequence":"first","affiliation":[{"name":"- Universidade Federal de S\u00e3o Jo\u00e3o Del Rei,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5710-421X","authenticated-orcid":false,"given":"Marisa Maria","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"Prefeitura Municipal de Divin\u00f3polis,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5012-8470","authenticated-orcid":false,"given":"Sebasti\u00e3o","family":"Pratavieira","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4833-239X","authenticated-orcid":false,"given":"Vanderlei Salvador","family":"Bagnato","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2939-7780","authenticated-orcid":false,"given":"Fernando de Pilla","family":"Varotti","sequence":"additional","affiliation":[{"name":"- Universidade Federal de S\u00e3o Jo\u00e3o Del Rei,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","published-online":{"date-parts":[[2019,3]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"458","DOI":"10.1016\/j.clindermatol.2016.02.018","article-title":"Diseases of the tongue","volume":"34","author":"Mangold AR","year":"2016","journal-title":"Clin Dermatol"},{"key":"ref2","first-page":"331","article-title":"Differential diagnosis of tongue lesions","volume":"34","author":"Laskin D","year":"2003","journal-title":"Quintessence Int"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"723","DOI":"10.1016\/j.joms.2016.10.012","article-title":"Leukoplakia-A Diagnostic and Management Algorithm","volume":"75","author":"Villa A","year":"2017","journal-title":"J Oral Maxillofac Surg"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"309","DOI":"10.1016\/j.oraloncology.2008.06.002","article-title":"Global epidemiology of oral and oropharyngeal cancer","volume":"45","author":"Warnakulasuriya S","year":"2009","journal-title":"Oral Oncol"},{"key":"ref5","doi-asserted-by":"crossref","first-page":"10845","DOI":"10.3748\/wjg.v20.i31.10845","article-title":"Black hairy tongue syndrome","volume":"20","author":"Gurvits GE","year":"2014","journal-title":"World J Gastroenterol"},{"key":"ref6","first-page":"627","article-title":"Common tongue conditions in primary care","volume":"81","author":"Reamy B V","year":"2010","journal-title":"Am Fam Physician"},{"key":"ref7","doi-asserted-by":"crossref","first-page":"67","DOI":"10.1056\/NEJMicm050117","article-title":"Black Hairy Tongue","volume":"354","author":"Korber A","year":"2006","journal-title":"N Engl J Med"},{"key":"ref8","first-page":"897","article-title":"Images in clinical medicine","volume":"337","author":"Newman CC","year":"1997","journal-title":"Black hairy tongue.
