Pleomorphic adenoma is the commonest benign neoplasm of the parotid gland and minor salivary glands. It is composed of epithelial and myoepithelial cells arranged in various morphological patterns. The concrete reasons contributing to a recurrent disease are obvious or attempts of accidental tumor spillage, enucleation with rupture and incomplete excision during operation. The other solid reasons that could contribute to recurrence are known incomplete pseudocapsule, extracapsular extensions, pseudopods of pleomorphic adenoma tissue, and satellite pleomorphic beyond the pseudocapsule matrix. Most recurrent pleomorphic adenoma are multinodular with different recurrent sites and time duration. We describe a case of 55-year-old lady who underwent left superficial parotidectomy for pleomorphic adenoma 14 years prior to current presentation. After 8 years, she presented with ipsilateral level II lymph node, in which excision showed pleomorphic adenoma. Within 2 years after excision, she experienced another multiple small neck swellings at the level II-III, in which histopathology examination of the excised masses were consistent with pleomorphic adenoma, without evidence of lymph node background to suggest metastasis.
