Salivary gland tumors are uncommon and their overall incidence is about 3 per 100000 per year. Salivary gland hemangioma makes up 1 % of all salivary gland tumors. Trismus resulting from parotid hemangioma is so rare. The patient was a 6-month-old boy with a huge lesion in his right parotid who referred to Shahid sadoughi hospital of Yazd, Iran. The lesion appeared at 4 months of age and had rapid growth and was suspected as hemangioma after clinical examination and patient had trismus. The lesion was excised without any complications. Five months after surgery, area of the lesion appeared normal. Parotid hemangioma has low potential to turn into malignant form but early detection and biopsy are necessary for decreasing complications. Removal of the mass was the best treatment for the patients with large or complicated hemangioma however, it should be performed with caution because the tissues may bleed profusely. Patients may have long term survival after surgery. M3 ER -
