Assessment of a cervical mass. Is it a matter of concern?

Lymphatic malformations (LMs) are vascular malformations resulting from prenatal errors in vascular development. Most are benign, and they are usually diagnosis at birth or before age 2 years. They can be located anywhere on the body, although their most common locations are the head and neck. They are classified as macrocystic, microcystic or mixed according to their anatomy. As regards diagnosis, most of these lesions can be detected through the physical examination, and imaging tests, chiefly sonography and MRI, can guide and complete the diagnosis. When it comes to treatment, there are no established protocols for the management of these malformations. The treatment is usually individualized, with methods such as laser, radiotherapy, local sclerotherapy, or surgery, although conservative treatment is increasingly recommended, especially for asymptomatic lesions.
