Intravenous Lobular Capillary Hemangioma of the Neck: A Report of 2 Cases

Background: Intravenous lobular capillary hemangioma (IVLCH) of the neck is a kind of rare benign tumor of vein. Purpose: In this paper, we report two female patients who were hospitalized because of neck masses. Results: The tumors in the neck veins of our patients were white oval masses with pedicle, clearly defined and of different sizes. Their immunohistochemical staining results showed CD31 (+), CD34 (+), SMA (+), ERG (+). The pathological diagnosis was intravenous lobular capillary hemangioma. Conclusions: Due to the location, morphology and immunohistochemistry, This lesion needs to be distinguished from other intravascular lesions such as thrombus, hemangiosarcoma and papillary endothelial hyperplasia.
