Hairy Tongue: Differential Diagnosis by Use of Widefield Optical Fluorescence.

Braz Dent J 2019 Mar-Apr;30(2):191-196. Epub 2019 Apr 4.

Núcleo de Pesquisa em Química Biológica (NQBio), UFSJ - Universidade Federal de São João Del Rei, Divinópolis, MG, Brasil.

Hairy tongue is a benign pathology, characterized clinically by hyperkeratinized plaques on the dorsal surface of the tongue, hairlike, whose coloration ranges from unpigment, whitish, yellowish, green, brown to black. 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.

Non-HPV Papillary Lesions of the Oral Mucosa: Clinical and Histopathologic Features of Reactive and Neoplastic Conditions.

Head Neck Pathol 2019 Mar 29;13(1):71-79. Epub 2019 Jan 29.

Department of Stomatology, Faculty of Dental Medicine, Université de Montréal Montreal, Centre-ville station, PO Box 6128, Montreal, QC, H3C 3J7, Canada.

Excluding human papillomavirus (HPV)-driven conditions, oral papillary lesions consist of a variety of reactive and neoplastic conditions and, on occasion, can herald internal malignancy or be part of a syndrome. The objectives of this paper are to review the clinical and histopathological features of the most commonly encountered non-HPV papillary conditions of the oral mucosa. These include normal anatomic structures (retrocuspid papillae, lingual tonsils), reactive lesions (hairy tongue, inflammatory papillary hyperplasia), neoplastic lesions (giant cell fibroma), lesions of unknown pathogenesis (verruciform xanthoma, spongiotic gingival hyperplasia) and others associated with syndromes (for instance Cowden syndrome) or representing paraneoplastic conditions (malignant acanthosis nigricans).

Black and Brown: Non-neoplastic Pigmentation of the Oral Mucosa.

Head Neck Pathol 2019 Mar 22;13(1):47-55. Epub 2019 Jan 22.

Louisiana State University, 1100 Florida Avenue, New Orleans, LA, 70119, USA.

Black and brown pigmentation of the oral mucosa can occur due to a multitude of non-neoplastic causes. Endogenous or exogenous pigments may be responsible for oral discoloration which can range from innocuous to life-threatening in nature. Physiologic, reactive, and idiopathic melanin production seen in smoker's melanosis, drug-related discolorations, melanotic macule, melanoacanthoma and systemic diseases are presented. Read More

Eradication of hairy mouth after oncological resection of the tongue and floor mouth using a diode laser 808 nm. Postoperative pain assessment using thermal infrared imaging.

Lasers Surg Med 2019 Jan 6. Epub 2019 Jan 6.

Department of Morphology, Experimental Medicine and Surgery, University of Ferrara, Ferrara, Italy.

Objectives: Vascularized soft tissue flaps are often harvested from hair-bearing areas, such as the radial forearm or anterolateral thigh, making their use in oral reconstruction problematic due to postoperative hair growth. The presence of intact hair follicles in free tissue transfer and continued hair growth at the recipient site can result in difficulties with oral hygiene, intraoral irritation, food trapping, and patient distress. This study was to evaluate the intraoral efficacy and safety of a diode laser 808 nm when used for hair removal. Read More

Cats use hollow papillae to wick saliva into fur.

Proc Natl Acad Sci U S A 2018 12 19;115(49):12377-12382. Epub 2018 Nov 19.

George W. Woodruff School of Mechanical Engineering, Georgia Institute of Technology, Atlanta, GA 30332-0405;

The cat tongue is covered in sharp, rear-facing spines called papillae, the precise function of which is a mystery. In this combined experimental and theoretical study, we use high-speed film, grooming force measurements, and computed tomography (CT) scanning to elucidate the mechanism by which papillae are used to groom fur. We examine the tongues of six species of cats from domestic cat to lion, spanning 30-fold in body weight. Read More

Section of Dermatology, Department of Experimental, Diagnostic and Specialty Medicine, University of Bologna, Bologna, Italy -

Melanocytes are found throughout the oral mucosa but usually go unnoticed because of their relatively low level of pigment production. When focally or generally active in pigment production or proliferation they may be responsible for several affections in the oral mucosae ranging from physiologic pigmentation, systemic diseases to malignant neoplasms. The diagnosis of oral pigmentations (OP) is usually challenging for the physician, but a careful examination of the oral cavity may reveal the first manifestation of underlying systemic diseases.

Diseases of the tongue.

Clin Dermatol 2016 Jul-Aug;34(4):458-69. Epub 2016 Mar 8.

Department of Dermatology, Mayo Clinic, Scottsdale, AZ.

The tongue is a complex organ involved in speech and expression as well as in gustation, mastication, and deglutition. The oral cavity, along with the tongue, are sites of neoplasms, reactive processes, and infections, and may be a harbinger of systemic diseases. This review includes both common and rare diseases that occur on the tongue, including: vascular and lymphatic lesions (infantile hemangiomas and oral varices), reactive and inflammatory processes (hairy tongue, pigmented fungiform papillae of the tongue, benign migratory glossitis, and fissured tongue), infections (oral hairy leukoplakia, herpes simplex and varicella-zoster virus infections, human papillomavirus, and candidiasis), premalignant lesions (leukoplakia and erythroplakia), malignant lesions (squamous cell carcinoma, Kaposi sarcoma, and lymphoproliferative diseases), and signs of systemic disease (nutritional deficiency and systemic amyloidosis).

In immunocompromised subjects, Epstein-Barr virus (EBV) infection of terminally differentiated oral keratinocytes may result in subclinical productive infection of the virus in the stratum spinosum and in the stratum granulosum with shedding of infectious virions into the oral fluid in the desquamating cells. In a minority of cases this productive infection with dysregulation of the cell cycle of terminally differentiated epithelial cells may manifest as oral hairy leukoplakia. This is a white, hyperkeratotic, benign lesion of low morbidity, affecting primarily the lateral border of the tongue. Read More

Black hairy tongue in a patient with amyotrophic lateral sclerosis.

J Int Soc Prev Community Dent 2016 Jan-Feb;6(1):80-3

Department of Surgical Science, Cagliari University, Cagliari, Italy.

Black hairy tongue (BHT) is a condition characterized by the elongation of filiform papillae associated with a marked discoloration, from yellowish-brown to black, and a thick lingual coating. BHT is usually observed in the elderly and in patients with limited self-sufficiency, as a consequence of poor oral hygiene. In this perspective, the patients affected by amyotrophic lateral sclerosis (ALS) represent a high-risk category for the occurrence of BHT. Read More

White lesions in the oral cavity: clinical presentation, diagnosis, and treatment.

Semin Cutan Med Surg 2015 Dec;34(4):161-70

Departments of Orofacial Sciences, Radiation Oncology, and Pathology, and the Helen Diller Comprehensive Cancer Center, University of California, San Francisco, California, USA.

White lesions in the oral cavity are common and have multiple etiologies, some of which are also associated with dermatological disease. While most intraoral white lesions are benign, some are premalignant and/or malignant at the time of clinical presentation, making it extremely important to accurately identify and appropriately manage these lesions. Due to their similar clinical appearances, it may be difficult sometimes to differentiate benign white lesions from their premalignant/malignant counterparts. Read More

Nectar uptake in bats using a pumping-tongue mechanism.

Sci Adv 2015 Sep 25;1(8):e1500525. Epub 2015 Sep 25.

Institute of Evolutionary Ecology and Conservation Genomics, University of Ulm, Ulm D-89069, Germany. ; Smithsonian Tropical Research Institute, Balboa, Panama.

Many insects use nectar as their principal diet and have mouthparts specialized in nectarivory, whereas most nectar-feeding vertebrates are opportunistic users of floral resources and only a few species show distinct morphological specializations. Specialized nectar-feeding bats extract nectar from flowers using elongated tongues that correspond to two vastly different morphologies: Most species have tongues with hair-like papillae, whereas one group has almost hairless tongues that show distinct lateral grooves. Recent molecular data indicate a convergent evolution of groove- and hair-tongued bat clades into the nectar-feeding niche. Read More

Mouthpart grooming behavior in honeybees: Kinematics and sectionalized friction between foreleg tarsi and proboscises.

J Insect Physiol 2015 Nov 9;82:122-8. Epub 2015 Oct 9.

Division of Intelligent and Biomechanical Systems, State Key Laboratory of Tribology, Department of Mechanical Engineering, Room 3407, Building 9003, Tsinghua University, 100084 Beijing, PR China. Electronic address:

The mouthpart of a honeybee is prone to contamination by granular particles such as pollen or dirt from the field. To clean the contaminated mouthparts, a honeybee swings its foreleg tarsi forward and backward to brush the proboscis continuously, sweeping the contaminant from the surfaces of the labial palpi, galeae, and bushy haired tongue (glossa). This grooming behavior has been documented but the dynamic characteristics therein have not been investigated yet. Read More

Differentiation-Dependent KLF4 Expression Promotes Lytic Epstein-Barr Virus Infection in Epithelial Cells.

PLoS Pathog 2015 Oct 2;11(10):e1005195. Epub 2015 Oct 2.

McArdle Laboratory for Cancer Research, University of Wisconsin School of Medicine and Public Health, Madison, Wisconsin, United States of America; Department of Medicine, University of Wisconsin School of Medicine and Public Health, Madison, Wisconsin, United States of America.

Epstein-Barr virus (EBV) is a human herpesvirus associated with B-cell and epithelial cell malignancies. EBV lytically infects normal differentiated oral epithelial cells, where it causes a tongue lesion known as oral hairy leukoplakia (OHL) in immunosuppressed patients. However, the cellular mechanism(s) that enable EBV to establish exclusively lytic infection in normal differentiated oral epithelial cells are not currently understood. Read More
