Natural killer T-cell lymphoma of the tongue.

Lymphoma, which represents about 5.4% of all neoplasms and, more significantly, 19% to 28% of malignant neoplasms, is the most common nonepithelial malignancy of the head and neck area in Koreans. Natural killer T-cell (NK/T-cell) lymphoma is a lymphoma of putative natural killer cell lineage. NK/T-cell neoplasms are generally rare, but they are more common in people of East Asian, Mexican, or South American descent. These neoplasms are highly aggressive and show a strong association with Epstein-Barr virus. The preferential site of extranodal NK/T-cell lymphoma is the nasal cavity, and there has been no report of NK/T-cell lymphoma developing from the tongue. We encountered a rare case of NK/T-cell lymphoma of the tongue, which we report with a review of the literature.

Proliferative myositis arising in the tongue.

We describe a rare case of proliferative myositis affecting the lateral border of the tongue. The site of the lesion and its gross pathological presentation were highly suggestive of a malignant process. Subsequent biopsy and characteristic histological appearance led to the diagnosis of this benign condition. This is the first reported case of a painful presentation of proliferative myositis involving the tongue. This report serves to remind the head and neck surgeon of the need to obtain histological diagnosis of malignancy before embarking upon radical surgical treatment. We recommend careful follow-up to ensure complete resolution of the lesion.

Bilateral white corrugated lesions on the lateral tongue surface.

A patient with bilateral hairy leukoplakia and candidiasis of the tongue was diagnosed and described. Lesions of the tongue that should be considered in the differential diagnosis include: idiopathic clinical leukoplakia, tobacco-induced leukoplakia, frictional keratosis, edema, lichen planus, galvanic lesions, geographic tongue, maceration, and chronic hyperplastic candidiasis. Hairy leukoplakia occurs predominantly on the tongue as in the patient described. The typical presentation is easily diagnosed but atypical cases may be diagnosed by their lack of response to antifungal treatment and histological exclusion of other lesions. The natural history of hairy leukoplakia needs further study. Hairy leukoplakia has not been reported in patients not infected by HIV; therefore, patients with hairy leukoplakia should be considered highly suspect for subsequent development of AIDS.

Tongue ulcerated by trauma: report of case.

A patient's nocturnal tongue biting resulted in a traumatic ulcer on the lateral border of the tongue. The ulcer resolved after a fractured restoration was repaired and topical triamcinolone was applied.

Laugier-Hunziker pigmentation.

Laugier-Hunziker pigmentation (LHP) is an acquired disorder of hypermelanosis characterized by mucocutaneous hyperpigmentation. LHP may resemble various disorders characterized by mucocutaneous pigmentation. A 58-year-old lady presented with progressively increasing number of variable sized, hyperpigmented macules over the lips, fingers, toes and nails. There was no family history of similar illness. Systemic examination and all relevant investigations were within normal limits. Histopathology of a skin lesion had features consistent with LHP. The diagnosis of LHP must be made only after relevant investigations to rule out any associated systemic involvement. This case further highlights that LHP is not restricted to European countries.

Tongue fissures. A classification and comparative prevalence study among 825 European Caucasian and 605 Xhosa Negro school children.

Six distinct patterns of tongue fissuring have been observed: plication, central longitudinal fissuring, double fissures, transverse fissures arising from a central fissure (type "A"), transverse fissures without a central fissure (type "B") and lateral longitudinal fissures. Some tongues exhibited more than one pattern. There was a significant correlation between double fissures and central longitudinal fissuring (P less than 0.002) but not between other forms of fissuring. No significant relationship was found between the occurrence of atrophic lesions and the prese-ce of fissuring. Significant differences were found between the prevalences in Xhosa and Europeans for central longitudinal fissuring, double fissures and both types of transverse fissures but not for plication. No significant differences were found between males and females and in the age distribution for those with and those without each type of fissuring. It is suggested that most tongue fissuring seen in children should be considered variations in normal anatomy rather than an abnormality.

[Tuberculosis of the tongue].

A case of coexisting tongue and pulmonary tuberculosis is presented. A 55 year old man, farmer, an alcohol abuser, suffered from respiratory symptoms infection was admitted to Dental Surgery Department because of carcinoma of tongue suspicion. His tongue was oedematous, stiff with numerous painful ulcerations. Thin-needle biopsy of the tongue revealed granuloma typical for tuberculosis. Chest x-ray examination revealed disseminated lesions and cavernous infiltration in the lungs. Tuberculosis of lungs and tongue was recognised. Antimycobacterial treatment was introduced. 2 weeks later, tuberculous bacilli were cultured. Excellent clinical and mainly-local (tongue) improvement has been achieved.
