title: Spontaneous resolution of an intraparotid hematoma with unknown etiology.
abstract: The malignant parotid lesions are fast growing and rapidly become symptomatic. Ultrasonography and fine needle aspiration biopsy are mainly used in the differential diagnosis of parotid lesions. The most common treatment of all parotid lesions is surgical excision. Here, we present a case of a very rapidly enlarging, painful parotid lesion with no etiology. A 30-year-old man presented with a rapidly progressive, enlarging, painful mass on the left side of the parotid region. The size of the lesion had enlarged rapidly day by day. The patient had no history of head and neck surgery or trauma. After evaluation of the patient with radiologic examinations, no certain diagnosis could be made; we thought that the patient might be experiencing spontaneous intraparotid bleeding with unknown etiology. We decided to wait for a time for spontaneous resolution. The lesion resolved spontaneously in a few months, without any complications or sequelae.
