Tuberculosis of the Parotid Gland

Abstract: Parotid gland involvement is extremely rare, even in countries in which tuberculosis is endemic. Clinically, it usually presents as a slow-growing mass indistinguishable from a malignancy. On imaging too, tuberculosis of the parotid may mimic neoplasm. The diagnosis of parotid tuberculosis needs a high degree of clinical suspicion. This paper highlights the clinical presentation, imaging findings, and importance of FNAC in diagnosis of this rare entity.

“…Other differential diagnoses are parotid cyst, collagen vascular disorders like sarcoidosis, and rarely malignant tumours. Ultrasonography, CT scan, and MRI are the imaging modalities used, but all of them have nonspecific findings [ 8 ]. Two types of parotid involvement have been described in ultrasonography findings, the parenchymal type, where there is diffuse involvement of superficial part of the parotid gland, and periparotid type, where intra- and periglandular lymph nodes are affected and might present as an abscess later [ 9 , 10 ].…”

“…A metanalysis of 49 cases of parotid tuberculosis showed presence of pulmonary tuberculosis in only 25% cases [ 7 ]. Cases described early in literature were confirmed after histopathology of surgically excised gland [ 4 ], but many cases reported in the last decade have been diagnosed with parotid tuberculosis by fine needle aspiration cytology (FNAC) [ 4 , 8 , 11 ]. FNAC has good sensitivity (81%–100%) as well as specificity (94%–100%) [ 12 ].…”

“…Acute bacterial parotitis may occur more often from Gram-positive pathogens such as Staphylococcus aureus , Fusobacterium spp., and Streptococcus spp [ 10 12 ]. Less frequent is parotitis from Mycobacterium tuberculosis usually in the context of extrapulmonary tuberculosis in an immunosuppressed patient [ 12 , 13 ]. Finally, infections within the buccal space may develop on the ground of dental infection spreading typically from the masticator space.…”

“…The extra pulmonary tuberculosis accounts for approximately 20% of overall active tuberculosis and can be seen in the lymph nodes, meninges, bones and kidneys. 5 Tuberculous lymphadenitis is the most common form of extrapulmonary tuberculosis and the cervical lymph nodes are commonly involved. However, the parotid gland involvement is extremely rare, even in countries in which tuberculosis is endemic.…”
