A 65-year-old male presented to us with a painful, progressively increasing swelling of the tongue of 8 months duration. There was no history of cough, fever, dysphagia, or weight loss. He was a nonsmoker, but a tobacco chewer for the past 15 years. He was an alcoholic since past 15 years. He was not a known case of diabetes mellitus, but a hypertensive since past 4 years and was on regular treatment for it. On examination, patient was well built with good general condition. Examination of oral cavity revealed an 8 × 6 cm firm swelling over the left side of anterior 2/3rd of tongue, crossing the midline, with smooth surface and well-defined margins. The lesion apparently looked like hemimacroglossia (). There was no deviation of tongue, with all movements being normal. No lymphadenopathy was found in the neck. Systemic examination did not reveal any abnormal findings. Clinical suspicion of submucosal carcinoma of tongue was entertained. Complete blood count was within normal limits. ESR was found raised to 35 mm in first hour. A deep punch biopsy from lateral aspect of the lesion was taken, which revealed granulomatous inflammation suggestive of tuberculosis (). Acid fast bacilli were found in Ziehl-Neelsen stained sections (). A histopathological diagnosis of tuberculosis was made. Mantoux test performed with PPD antigen measured 18 mm after 72 hours reading. ELISA test for HIV was nonreactive. Chest X-ray was within normal limits. With a final diagnosis of primary tuberculoma of tongue, patient was started on antitubercular therapy with a four drug regimen for 6 months. Dramatic improvement was observed within 2 months of therapy. Size of the lesion was significantly reduced, from an apparent hemimacroglossia to a small nodular lesion. After 6 months the patient was completely cured and is on regular followup with no residual or recurrent lesion.
A 33-year-old black female attended the oral medicine clinic at the Medunsa Oral Health Centre, University of Limpopo, complaining of a painful sore on the upper left labial mucosa of about 3 weeks duration. She appeared to be in good health. The patient did not smoke or drink alcohol, and she claimed to be HIV-seronegative as she had been tested for HIV infection about three months previously.\nThere were two ulcers surrounded by a wide area of erythema, one on the upper left labial mucosa that was painful, and one on the ventral surface of the tip of the tongue (). The margins of both ulcers were slightly elevated and indurated. The dorsal surface of the anterior margin of the tongue was hyperaemic with a lobulated appearance ().\nHistological examination of the labial mucosal ulcer showed necrotic tissue and chronically inflamed granulation tissue. Scattered epithelioid cells were present, and Ziehl-Neelsen staining revealed the presence of acid fast bacilli leading to the final diagnosis of oral tuberculosis (Figures and ).\nThe patient was referred to the Department of Internal Medicine at the Dr. George Mukhari Hospital. She proved to be HIV-seropositive with a CD4+ T cell count of 429 cells/mm3. The general physical examination was unremarkable, the chest radiograph did not show any evidence of tuberculosis, and other laboratory investigations that were deemed necessary were all within the range of normality. A nine-month anti-TB drug regimen of isoniazid, rifampicin, pyrazinamide, and ethambutol, was prescribed.\nThe patient did not receive antiretroviral treatment for a reason to be explained below.\nFour weeks after initiation of the anti-TB treatment the oral lesions were strikingly improved (Figures and ), and 8 weeks later the previously affected lip and tongue looked normal.
