Abstract
Pleomorphic adenoma is a benign mixed tumor, which is composed of myoepithelial and epithelial cells. A fibrous capsule separates these cells from the surrounding tissues. Pleomorphic adenoma is the most common salivary gland tumour accounting for 40-70% of all major and minor salivary gland tumours. It is also the commonest minor salivary gland benign tumours accounting for 70% of all tumours. Hard palate is the commonest site followed by upper lip, buccal mucosa, tongue, floor of mouth, retromolar trigone. This case report discusses a case of pleomorphic adenoma of hard palate in an old man after complete excision of the tumour, which was confirmed by a biopsy specimen.
Highlights
The pleomorphic adenoma otherwise called benign mixed tumor, is the most common major salivary glands neoplasm.[1]
The aim of this paper is to describe a case of pleomorphic adenoma of minor salivary gland in palate of a young woman patient who was treated with wide surgical excision showing no evidence of recurrence one year post-operative follow up
The final histopathology report confirmed the diagnosis of pleomorphic adenoma of minor salivary gland of hard palate
Summary
The pleomorphic adenoma otherwise called benign mixed tumor, is the most common major salivary glands neoplasm.[1]. To 77% of parotid tumors, 44% to 68% of submandibular tumors and 33% to 43% of minor gland tumors.[2] Pleomorphic adenomas are derived from a mixture of ductal and myoepithelial elements.[2,3] The terms pleomorphic adenoma and mixed tumor both represent attempts to describe the tumor’s unusual histopathologic features.[4] The tumor often has a prominent mesenchyme appearing stromal component. It is not truly a mixed neoplasm that is derived from more than one germ layer.[1,4]. The final histopathology report confirmed the diagnosis of pleomorphic adenoma of minor salivary gland of hard palate
