Dilemma in #Diagnosis-Huge Preauricular Sinus Mimicking Parotid Tumor by Ling Xiu Ngui in BJSTR
Abstract
Objective: This paper reports a case of huge preauricular sinus mimicking parotid tumour to highlight the difficulty in obtaining a
correct
diagnosis.
Background and Case Report: This case describes a 51-year-old
gentleman who presented with a huge, soft and painless swelling over
left parotid region which was progressively increasing in size over two
years. The swelling appeared to push the left ear lobule upward and
on palpation, the swelling did not go beyond the zygomatic arch. Fine
needle aspiration was unsatisfactory. Ultrasonography scan showed left
parotid tumour. The diagnosis of preauricular sinus was made only upon
excision of the mass under general anaesthesia. Post operatively, the
recovery was good and there was no complication.
Conclusion: Though it is extremely rare, preauricular sinus
should be considered as a differential diagnosis of painless soft
parotid swelling.
