Abstract

|
Among a variety of malignant types for parotid gland tumors, intracapsular carcinoma ex pleomorphic adenoma which is classified as a non-invasive tumor has been reported rarely. We report a case of a 69-years old patient, who presented with a left parotid mass that was detected 30 years ago. Fine needle aspiration biopsy result of the mass was “suggestive of pleomorphic adenoma”. Superficial partial parotidectomy was performed for the mass and the permanent pathologic finding was “intracapsular carcinoma ex pleomorphic adenoma” which was a salivary ductal carcinoma with well-preserved myoepithelial cells surrounding the malignant epithelial cell clusters. Surgical resection is the main treatment modality for the treatment of intracapsular carcinoma ex pleomorphic adenoma. Herein, we present the case with a review of literature.
