Head and Neck Lymphatic Malformations

Vascular anomalies correspond to a group of lesions related to disorders of vascular development, which to date remain a diagnostic and therapeutic challenge for treating physicians. Lymphatic malformations (LM) are congenital malformations that manifest as benign hamartomatous tumors of the lymphatic vessels with a marked predilection for the head, neck and oral cavity. In general terms, LM are classified as macrocystic, microcystic or a combination of both depending on the size of the lesion, which can lead to anatomical alterations and even functional deficits. The aim of this article is to provide a brief and accurate review of head and neck lymphatic malformations considering their clinical aspects, imaging tools and treatment options.
