Malignant parotid tumors are uncommon tumors. Although pleomorphic adenoma is the commonest benign tumor of the parotid accounting for 65% of tumors but malignant tumors are also seen frequently in parotid gland. Normally these tumors are slow growing with a long history of lump in the parotid gland. The rapid growth phase in these tumors indicate malignant transformation. The involvement of facial nerve is a late symptom and denote advance stage. We are presenting a giant malignant tumor of the parotid gland measuring 22cm x 15cm in a lady of 50 years. To the best of our knowledge this is the biggest tumor reported so far in Pakistan.
