Hemangioma is often found in the head and neck region, but it occasionally occurs in salivary glands, especially in the submandibular gland. A 40-year-old male was referred to our division with a painless swelling in the left submandible. A hen's egg-sized mass with an elastic, soft and flexible feeling was observed in the left submandibular region. Abnormal change in the oral cavity was not found. The clinical diagnosis was a suspected salivary gland tumor. The tumor was surgically removed under general anesthesia. The dark red tumor was partially adhered to the submandibular gland, however, the border between the lesion and the surrounding tissues was clear. The mass, which consisted of the tumor and submandibular gland, was easily removed in a group. Since malignancy was not ruled out due to its rapid growth, an instant pathologic examination was performed during the surgery. Since no signs of malignancy were found in the examination, additional procedures such as extensive excision were not necessary during surgery. The final pathological examination revealed that the lesion was mainly composed of arteries, veins and capillaries of various sizes, and there was no malignant change in the lesion. Thus, considering the clinical and pathological findings, the tumor was diagnosed as a cavernous hemangioma in the submandibular gland. Two years have passed since the surgery, and both his general and local conditions are good with no sign of recurrence of symptoms.
