1/10. Psychotropic agent-induced black hairy tongue.

    Black hairy tongue is characterized by an abnormal coating of the dorsal surface of the tongue. Although the cause is unknown, several precipitating factors may be implicated in the pathogenesis of this disorder. A case is presented in which black hairy tongue appeared subsequent to the administration of fluoxetine hydrochloride, thiothixene hydrochloride, benztropine mesylate, and clonazepam for bipolar affective disorder.

2/10. Topical tretinoin: a new treatment for black hairy tongue (lingua villosa nigra).

    Black hairy tongue is the name given to the appearance of an abnormal coating of the tongue and occurs only 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 and often no definite cause can be identified. A number of aetiologic factors have been implicated including the administration of topical or systemic antibiotics, poor oral hygiene, smoking, alcohol and the use of mouthwashes. Often there are no symptoms other than the aesthetic or anxiety over its aetiology. Some patients complain of gagging, nausea, alteration of taste or halitosis. The condition may be very persistent and recognized treatments include brushing with a soft tooth brush which is enhanced by the prior application of a 40% solution of urea, scraping, topical triamcinolone acetonide, gentian violet, thymol, salicylic acid, vitamin b complex, and surgical excision of the papillae.

3/10. Hairy leukoplakia with involvement of the buccal mucosa.

    Oral hairy leukoplakia occurs mainly on the tongue of human immunodeficiency virus (hiv)-infected persons. An hiv-infected patient with hairy leukoplakia involving the tongue and buccal mucosa was studied by light and electron microscopic methods, in situ hybridization, and polymerase chain reaction. Our findings indicate that hairy leukoplakia may involve the buccal mucosa and should be considered in the differential diagnosis of white oral lesions in hiv-positive patients. Epstein-Barr virus particles were found in the epithelial cells of both buccal and tongue mucosa.

4/10. Unilateral black hairy tongue in trigeminal neuralgia.

    Unilateral hairlike discoloration of the tongue is described in a patient with ipsilateral mandibular division trigeminal neuralgia. This unusual physical sign coincided with the patient's painful trigger zone and was attributed to hypertrophy of keratinized filiform papillae, where guarded avoidance of mechanical stimulation over time prevented normal desquamation.

5/10. Hairy tongue: a case report.

    Hairy tongue or black hairy tongue is a benign condition characterized by hypertrophy of the filiform papillae that give the dorsum of the tongue a furry appearance. The color of the elongated papillae varies from yellowish white to brown or black. The etiology is unclear, but the disorder has been associated with numerous predisposing conditions such as heavy smoking, poor oral hygiene, use of topical or systemic antibiotics, systemic corticosteroid therapy, yeast infections, and radiotherapy for head and neck malignancies. A case is presented in which a hairy tongue appeared in a 67-year-old man.

6/10. Black hairy tongue associated with olanzapine treatment: a case report.

    Olanzapine is an atypical antipsychotic drug approved for acute and long-term treatment of bipolar disorder. Although relatively safe as compared to other classical antipsychotic medications, there are a number of uncommon adverse effects of olanzapine such as oral cavity lesions. In addition to the relatively common side effect of dry mouth, several articles have reported an association between olanzapine treatment and the development of oral lesions such as apthous stomatitis, pharyngitis, glossitis and oral ulceration. Although there are several cases in which the tongue was affected in conjunction with stomatitis or pharyngitis, we could not find a case report indicating a direct relationship between olanzapine use and a tongue lesion. We present here the case of a patient with bipolar disorder, who developed recurrent black hairy tongue on two different occasions following the addition of olanzapine to lithium treatment. In the present case, xerostomia (dry mouth), which is an adverse reaction of both olanzapine and lithium, may have played a role in the development of black hairy tongue. All agents with a possible side effect of xerostomia may predispose patients to black hairy tongue, especially when they are administered in combination. To preclude the development of this complication with such drugs, extra time and effort should be given to improving oral hygiene.

7/10. Black hairy tongue.

    Black hairy tongue is a benign disorder characterized by hypertrophy of the filiform papillae of the tongue. A brownish-black discoloration of the papillae occurs. The etiology is unclear, but the disorder has been associated with numerous predisposing conditions. Although black hairy tongue is usually cured by removal of these factors, a variety of measures, particularly brushing of the tongue, may aid in resolution.

8/10. halitosis and abuse of antibiotics. Report of a case.

    A case of halitosis caused by the abuse of antibiotics is presented. The abuse of tetracycline resulted in a black hairy tongue and halitosis in this patient. Periodontal therapy and the withdrawal of tetracycline corrected these problems. This is the first patient with halitosis due to abuse of tetracycline seen in our clinic.

9/10. Regression of oral hairy leukoplakia during zidovudine therapy.

    We describe two patients with human immunodeficiency virus infection and oral hairy leukoplakia whose tongue lesions resolved on oral zidovudine therapy. During therapy, each patient had a measurable reduction in human immunodeficiency virus antigen corresponding with clinical regression of oral lesions. The clinical course suggests that zidovudine may have contributed to the resolution of these lesions either indirectly through immunologic improvement or through an antiviral effect.

10/10. Black hairy tongue. A scanning electron microscopic study.

    A patient with tongue malignancy associated with a black hairy tongue is presented. Specimens from e area fo the black hairy tongue and from a normally appearing part were studied with the scanning electron microscope. The "hairs" consisted of elongated filiform papillae due to accumulated keratinized layers. In-between these layers, fungi and bacteria were found. The aetiology of the blck hairy tongue in this patient is discussed.
