Key clinical message: Angiosarcoma is a rare malignant disease with an extremely poor prognosis, showing rapid progression of the local tumor and/or distant metastases. Although multidisciplinary approach including systemic chemotherapy and radiation therapy is ideal for this disease, surgical resection have a role in disease control and should be performed as soon as possible.
Abstract: Angiosarcomas originating from the tongue are rare and have extremely malignant features, leading to a poor prognosis. Herein, we report the case of a patient with angiosarcoma arising from the tongue who was successfully treated surgically. A 71-year-old man was diagnosed with a mass on the right side of his tongue and visited the Department of Oral and Maxillofacial Surgery at our hospital. The patient was referred to our department for further examination and treatment after a biopsy of the right edge of the tongue. An irregularly raised tumor 50 mm in length was noted on the right lingual border. The preoperative diagnosis was a primary angiosarcoma of the tongue (clinical stage, T3N2bM0, Stage IV). As his tumor had been growing rapidly, he emergently underwent partial right-sided tongue resection and right neck dissection without reconstructive surgery. The histopathological diagnosis was pT3N0. Postoperatively, the patient showed no signs of recurrence or metastasis during the 1-year follow-up. As for angiosarcomas, surgical resection is the only curative treatment, and surgery should be performed as soon as possible after the final diagnosis.
