Polymorphous Adenocarcinoma of the Parotid Gland: A Rare Entity in Asians With a Unique Cystic Presentation
Polymorphous adenocarcinoma (PAC) of the parotid is a rare entity with minimal reported incidences in the Asian population. It generally presents as a solid tumor and is considered a diagnostic dilemma due to morphological diversity and variable histological patterns. This article reports a unique fluid-filled PAC of the parotid gland mimicking a cystic lesion in an Indian male, with a review of relevant literature. A 64-year-old male patient presented with a slow-growing swelling of the left parotid region for the last 10 years. The cytology report suggested a cystic swelling. The patient underwent superficial parotidectomy. A detailed histopathological examination confirmed it as a classical variant of PAC. He remains disease-free over 24 months post-surgery follow-up.
期刊介绍：
Clinical Case Reports is different from other case report journals. Our aim is to directly improve global health and increase clinical understanding using case reports to convey important best practice information. We welcome case reports from all areas of Medicine, Nursing, Dentistry, and Veterinary Science and may include: -Any clinical case or procedure which illustrates an important best practice teaching message -Any clinical case or procedure which illustrates the appropriate use of an important clinical guideline or systematic review. As well as: -The management of novel or very uncommon diseases -A common disease presenting in an uncommon way -An uncommon disease masquerading as something more common -Cases which expand understanding of disease pathogenesis -Cases where the teaching point is based on an error -Cases which allow us to re-think established medical lore -Unreported adverse effects of interventions (drug, procedural, or other).
