Vascular anomaly of the parotid gland: case report.

Abstract

ntroduction. Vascular anomalies of the parotid gland are rare congenital defects and encompass variations in vascular structure and arterial blood supply. Due to the rarity of these defects, the diagnosis and treat- ment of vascular anomalies of the parotid gland can be complex and require an individualized approach. Treatment of these anomalies may include conservative methods or surgical interventions, depending on the nature of the anomaly and the severity. Case presentation. A 50-year-old woman with a right parotid gland neoplasm was examined and a surgical intervention was performed. During removal of the mass, no large feeding vessels could be found. The histopathological examination showed the presence of venous vessels, arterioles, dilated ectatic venules lined with flat endothelial lining, lymphatic vessels, and smooth muscle. The immunohistochemical study showed positivity for vascular markers. Based on labo- ratory studies, a diagnosis of vascular malformation of the parotid salivary gland was established. Conclusions. Vascular anomalies of the parotid glands in adults should be considered hyperplasias, which can be easily removed without damaging the gland’s structure, as they are more commonly located at its periphery.
