SABIR, Η; KUMBHARE, S; ROUT, P and KUMAR, R. Abnormality in the right mandibular angle and large swelling in the left facial area - an unusual case. S. Afr. dent. j. [online]. 2015, vol.70, n.4, pp.159-163. ISSN 0375-1562.
A large swelling in the facial region of long duration generally suggests benign etiology. We report a case of large asymptomatic swelling in the left facial region which was clinically diagnosed to be a benign salivary gland tumour. The radiological investigations also suggested parotid gland tumour of benign etiology along with a fortuitous discovery of a Stafne bone defect in the right angle of mandible. The histopathological report however confirmed the tumour to be a case of acinic cell carcinoma of the left parotid gland. The patient underwent total parotidectomy and postoperative radiotherapy and has been disease- free for the past three years without any evidence of residual or recurrent lesion. The clinical, radiological, histopathological, and therapeutic aspects of acinic cell carcinoma and the radiological evaluation of the Stafne bone defect are analyzed along with literature review.
