Primary parotid tuberculosis mimicking parotid neoplasm: a case report.

Birkent H, Karahatay S, Akcam T, Durmaz A, Ongoru O - J Med Case Rep (2008)

Bottom Line: Radiologic investigations revealed a well-defined, solid, mass lesion located in the posterior part of the superficial lobe of the right parotid gland.A provisional diagnosis of a neoplasm of the parotid gland was made and a right superficial parotidectomy was performed.The patient was commenced on antitubercular chemotherapy.

ABSTRACT

Introduction: Tuberculosis of the parotid gland is a rare clinical entity which causes some difficulties in diagnosis because of the similarities in presentation to that of a neoplasm. Diagnosis mainly relies in the treating physician having a high index of suspicion. The diagnosis is generally overlooked by otolaryngologists and most cases are undergoing unnecessary surgery.

Case presentation: A 20-year-old male presented with a mass in the right parotid region. The mass had been present for one year. Physical examination revealed a mobile, non-tender mass occupying the superficial lobe of the right parotid gland. Radiologic investigations revealed a well-defined, solid, mass lesion located in the posterior part of the superficial lobe of the right parotid gland. A provisional diagnosis of a neoplasm of the parotid gland was made and a right superficial parotidectomy was performed. Histopathologic examination of the specimen was reported as tuberculosis of the parotid gland. The patient was commenced on antitubercular chemotherapy.

Conclusion: Although rare, tuberculosis should be kept in mind and considered in the differential diagnosis of patients presenting with a solitary tumor in the parotid gland in order to avoid unnecessary surgery.

Figure 1: An axial fat saturated T2-weighted image through the parotid gland demonstrates a well-defined high signal intensity mass in the superficial area of the right parotid gland.

Mentions: A provisional diagnosis of a neoplasm of the parotid gland was made and the patient was investigated accordingly. The complete blood count, erythrocyte sedimentation rate, other biochemical investigations and chest X-ray were normal. Ultrasound examination (US) showed a well-defined, hypoechoic solid mass lesion in the superficial lobe of the right parotid gland. Fine needle aspiration cytology was performed, but the cytological findings were not diagnostic. Magnetic resonance imaging (MRI) revealed a well-defined mass lesion, measuring 16 × 21 × 30 mm in size, hypointense on T1-weighted images, and hyperintense on T2-weighted images with homogenous contrast enhancement, located in the posterior part of the superficial lobe of the right parotid gland (Figure 1).
