Spontaneous Regression of Lymphatic Malformation -A Rare Case of Transient Macroglossia

Lymphatic malformation (LM) is a rare benign proliferation of dilated lymphatic vessels with inappropriate communication, filled with lymphatic fluid and lined by endothelial cells. Its occurrence is rare in the oral cavity; however, inside the oral cavity most common site is anterior two-thirds on the dorsum of the tongue, presenting as macroglossia. Macroglossia compromises the airway, often leads to obstructive sleep apnea, malocclusion, and speech and mastication difficulty. The main objective of tongue LM treatment is to preserve the taste sensation, restoration of the tongue size for articulation and cosmesis. We report a rare case of transient intermittent macroglossia due to LM. The patient presented with painful swelling of the tongue, relative macroglossia. There was spontaneous regression of LM with antibiotics and corticosteroids. LM can grow suddenly due to infection or hemorrhage and can shrink spontaneously. Upon treatment of the infection, there is spontaneous regression, total or partial. Therefore, expectant management should be considered in the treatment of tongue LM, to preserve the functions of tongue.
