Acquired lymphatic malformations of the buccal mucosa: A case report

: Lymphatic malformation is a rare disorder caused by expansion and proliferation of the lymphatic vessels. About 50% of lymphatic malformations are present at birth, and 90% are diagnosed before the age of 2 years. The most common site of lymphatic malformation in the oral cavity is the anterior two-thirds of the tongue, and involvement of the buccal mucosa is relatively unusual. Treatment of lymphatic malformation includes surgical excision, sclerotherapy, laser therapy, radiofrequency ablation, or a combination of these interventions. In many cases, surgery or sclerotherapy is the treatment of choice. However, there is currently no consensus on an optimal treatment approach. Here, we report an unusual case of lymphatic malformation in the buccal mucosa of an older adult that was surgically excised.
