Mucoepidermoid carcinoma

By Dr. Vishaal Bhat on Tuesday, 1 January, 2008 with 0 comments

  • Most common malignant salivary gland tumour; accounts for 2-10% of major salivary gland tumours and 10-40% of minor salivary gland tumours

  • Most common in 35-65 year age group; however, it can affect children and adolescents

  • They are slowly growing firm masses that are often clinically indistinguishable from the more common pleomorphic adenoma, and range in size from 1-4 cm.

  • Histologically these tumours are composed of epidermoid cells, mucus-secreting cells and intermediate cells; classified as low, intermediate and high-grade

  • The histologic grade is directly related to prognosis—survival rate in patients with low-grade tumours is 90-100%; intermediate and high-grade tumours tend to show local invasion, recurrence, and metastases, with survival rates of 40-60%.
