Tumors of salivary glands are uncommon and comprise of about 2%–4% of all head and neck tumors. About 75%–80% of these tumors are benign and include pleomorphic adenoma, monomorphic adenoma, oncocytoma, and papillary cystadenoma lymphomatosum. Mucoepidermoid carcinoma is the most common malignant tumor of salivary glands, representing 5–10% of all salivary gland tumors. Although known to be metastatic to local lymph nodes, distant metastases are rare (especially, with low and intermediate grade tumors). Histologic grade and the expression of various mucin glycoproteins are useful prognostic indicators. We present a case of mucoepidermoid carcinoma of parotid gland origin with distant metastases which is an uncommon occurrence with intermediate grade tumors. Also, this is the first reported case of humoral hypercalcemia of malignancy secondary to mucoepidermoid carcinoma.
