Mixed Hemangioma of Tonsil: A Rare Localization of this Tumor

Hemangiomas are benign tumors of the blood vessels. Although most commonly associated with the skin, it can also occasionally be found in mucous membranes, the brain, and the viscera. The tonsillar localization is uncommon and rarely reported in the literature. The risk of bleeding complications and its impact on the upper airway can make the management of these tumors more complicated. We report the case of a 28-year-old patient, with no pathological history, who was referred to us to manage a formation in the left tonsillar region. The patient was completely asymptomatic. Physical examination showed a tumor originating from the upper pole of the left tonsil. The cervical computed tomography scan showed an iso-dense tissue formation at the expense of the left tonsillar region. The patient was operated on under general anesthesia and a resection of the tumor mass was performed without a hemorrhagic incident. The histopathological examination confirmed the diagnosis of mixed capillary and venous hemangioma and the resection was complete. The outcome was favorable after a 12-month follow-up. Tonsilla hemangiomas are a rare clinical entity that all ENT surgeons should be familiar with to better choose the treatment course to avoid bleeding complications and recurrences.
