Black hairy tongue occurs on the dorsum of the tongue, and is characterised by a black, yellowish, or brown plaque with hairlike structures which result from benign hyperkeratosis of the filiform papillae. It may be associated with several conditions such as smoking, oral antibiotics or candida infection. However, the definite etiology is unknown. We report a case of black hairy tongue without any associated condition.

Black hairy tongue is a benign disorder characterized by hypertrophy of the filiform papillae of the tongue. A brownish-black discoloration of papillae occurs. the etiology is unclear, but the disorder has been associated with numerous predisposing conditions such as poor oral hygiene, medication, and smoking. Herein we report a case of black hairy tongue and it was successfully treated with simple brushing.

Black hairy tongue is a benign skin condition characterized by dark brown or black patches on the tongue, due to hypertrophied filiform papillae. Although the cause of the disease is uncertain, there are several predisposing factors such as poor oral hygiene, smoking and medication. Herein, we report a case of black hairy tongue that developed after the use of psychotropic agents

Black hairy tongue is the name given to the appearance of an abnormal coating of the tongue and occurs in adults. It is the result of hyperkeratosis of the filiform lingual papillae which, on gross examination appear hair-like with a variable tinctorial aspect from yellow-brown to black. The pathogenesis is unknown. A number of etiologic factors have been implicated including the administration of topical or systemic antibiotics, poor hygiene, smoking, alcohol and the use of mouthwashes. We report a case of black hairy tongue that may be associated with oral administration of minocycline.

Morsicatio is a condition caused by habitual chewing of the lips (labiorum), tongue (linguarum), or buccal mucosa (buccarum). Clinically, it often produces a shaggy white lesion caused by pieces of the oral mucosa torn free from the surface. The condition is generally found among people who are stressed or psychologically impaired. Most patients with this condition are not even aware of their biting habit. Clinically, morsicatio mimics hairy leukoplakia, and sometimes, it may be confused with other dermatologic diseases involving the oral cavity. It is rarely described in pathologic and dermatological textbooks. Histological features are distinctive, however, being careful to make a correct diagnosis can help one avoid providing inappropriate treatment. In this report we describe three cases of morsicatio, one that developed in the lower lip and the others that developed on the side of the tongue.

Tobacco smoking is one of the most important risk factors for the development of oral mucosal lesions such as leukoplakia and hairy tongue. Controversy exists in the literature, however, about the prevalence of oral lesions in smokers. The aim of this study was to evaluate oral lesions in male smokers compared with nonsmokers in Hamadan. A total of 516 male participants were assessed, 258 of whom were smokers and 258 of whom were healthy nonsmokers. The prevalence of lesions was evaluated by clinical observation and biopsy. We found that the most prevalent lesions among smokers were gingival problems and coated tongue; smokers had significantly more lesions than did nonsmokers. Malignant and premalignant lesions were found in a higher age range. Among all participants in our study, we found a large number of oral mucosal lesions in smokers that had a strong correlation with smoking. Dental services need to implement care and health education for smokers to promote health.

Erlotinib is a tyrosine kinase inhibitor that acts on the epidermal growth factor receptor (EGFR). There have been many reports of the mucocutaneous side effects related to several EGFR inhibitors (EGFRIs). However, no case of black hairy tongue (BHT) associated with EGFRI has been reported. Herein, we report the first case of erlotinib-induced BHT in a 61-year-old man with advanced lung cancer. Considering recent use of EGFRIs worldwide, dermatologists should recognize the possible occurrence of BHT associated with EGFRIs such as erlotinib.

"Leukoplakia-like" plaque on the tongue is an uncommon skin manifestation of secondary syphilis. Skin lesions of secondary syphilis usually have numerous presentations, which mimic many other skin diseases, especially in the presence of HIV co-infection. Oral hairy leukoplakia (OHL) is characterized by corrugated whitish patches and plaques on the lateral border of the tongue. It is frequently and strongly associated with HIV but may appear in other diseases. A 47-year-old man with HIV and receiving HAART therapy developed a leukoplakia-like plaque on the tongue, which was first suggestive of OHL but was eventually diagnosed as secondary syphilis.

Oral hairy leukoplakia (OHL) is caused by the reactivation of a previous Epstein-Barr virus (EBV) infection in the epithelium of the tongue. Most lesions are characterized by corrugated whitish patches on the lateral border of the tongue. It is frequently associated with AIDS, but cases in patients with other immunosuppressed states have also been reported. In leukemia patients, OHL is rarely encountered, and appears only after chemotherapy. We report a case of OHL which occurred as a presenting sign of acute myeloid leukemia (AML) in a previously healthy 15-year-old child. A 15-year-old boy presented with a whitish patch on the left lateral border of the tongue. The biopsy specimen revealed papillomatosis, hyperkeratosis, acanthosis and ballooning degeneration in the stratum spinosum. The patient was EBV seropositive, and PCR analysis of EBV DNA in the lesional tissue was positive. After the diagnosis of OHL in dermatologic department, the patient was referred to pediatrics due to the abnormal peripheral blood smear, and was diagnosed with AML.
