Abstract

Tuberculous granuloma of the tongue is a rare entity and constitutes a negligible percentage of all inflammatory lesions of that organ. Herein, we report two cases of granulomatous lesion of the tongue of tuberculous origin, both presented with only a small swelling. Fine-needle aspiration cytology (FNAC) and biopsy proved them to be granulomatous lesions. Antitubercular drugs (ATDs) were started, lesions healed completely without any residual effect.

 Introduction



Granuloma is a form of chronic inflammatory disorders, which can occur in almost every organ of our body. Tubercle bacillus is one of the most common causes of granulomatous lesions. Of course, as an organ tongue is an unusual site for granuloma. We present two cases, both of them presented with swelling over the dorsum of the tongue. Fine needle aspiration cytology (FNAC) or biopsy of those lesions proved them to be granuloma. They responded well with antitubercular drugs (ATDs) and disappeared fully without any complication.

 Case Report



Case 1

A 55-year-old female presented with an irregular swelling of about 1 cm diameter at the base of tongue [Figure 1]b for the past 6 months. The swelling was suspected as squamous cell carcinoma clinically. Biopsy from the lesion revealed a granulomatous lesion [Figure 2]b. Sputum test for tubercle bacillus was negative. Chest X-ray also was normal. With ATD, the swelling started to reduce in size and ultimately disappeared completely.{Figure 1}{Figure 2}

Case 2

An 18-year-old-female reported with swelling of 0.5 cm diameter at the right lateral side of tongue [Figure 1]a for the past 2 months. FNAC of the swelling disclosed a granulomatous lesion [Figure 2]a. Chest X-ray and Mantoux test were negative. ATD was commenced empirically. The swelling reduced fully 1 month after starting of drugs.

In both the cases, there was no complaint such as pain, dysphagia, or cervical lymphadenopathy. There was also no history of trauma from sharp tooth, ill-fitting denture, etc. Past or contact history for tuberculosis (TB) was not positive too. They were HIV negative and were not receiving any immunosuppressive drug for any other purpose.

In both the cases, ATDs (drugs such as, Isoniazid, Rifampicin, Pyrazinamide, Ethambutol – for the first 2 months, followed by Isoniazid, Rifampicin – for the next 4 months) were given for a total period of 6 months and the patients were cured completely. Six-month period of follow-up after completion of ATD course was uneventful.

 Discussion



There are different causes of granulomatous reaction. Starting from bacterium like tubercle bacillus and fungus like Histoplasma, various autoimmune disorders, foreign body, etc., can play a role as an etiological agent for granuloma formation. TB usually affects lungs but the bacilli can reach hematogenously to other organs including oral cavity and can involve tongue also.[1] 20% TB cases affect extrapulmonary organs.[2] In the head–neck region, TB cases are usually seen as cervical lymphadenitis, accounting for 95% of cases.[3] The oral cavity shows 0.2% to 1.5% of all cases of extrapulmonary TB and mostly due to secondary to pulmonary TB.[4] Oral cavity TB is rare due to continuous showering of oral mucosa with saliva and natural resistance of oral mucosa to Mycobacterium bacilli.[5] Relative paucity of lymphoid tissue in the tongue is another protecting factor.[6] In oral TB cases, the tongue being most commonly affected organ.[7],[8] In 1761, Morgagni first described a case of lingual TB.[9] TB of the tongue is commonly seen in immunocompromised patients, males and smokers.[10] Poor oral hygiene and breech of tissue due to trauma are other risk factors.[5] Aird described five pathological types of tuberculous lesion of tongue[11] – (1) Tuberculous ulcer (2) Tuberculoma (3) Tuberculous Fissure (4) Tuberculous papilloma, and (5) Tuberculous cold abscess. Macroglossia is an extremely rare presentation.[6] Clinically, the most common form of lingual TB is ulcer along the lateral border of the tongue.[12] Our cases presented as swelling over the tongue. Low number of cases is probably due to underreporting,[13] along with the varied presentation of the disease leads to dilemma for the clinicians. Investigations suggested for confirmation are FNAC and biopsy of the lesion, particularly to demonstrate the granuloma. Actually, ultimate confirmation is complete response to standard ATDs. Some highly specific techniques like Cartridge based nucleic acid amplification technique and polymerase chain reaction are available now-a-days.
