Oral Hemangiolymphangioma Presenting As Gingival Enlargement: A Rare Case With Literature Review

Vascular malformations are anomalies that are caused by disturbances in vasculogenesis. Depending upon the dominant structure present histologically, they may be found in different combinations of vascular elements and are named hemangiolymphangioma (HLA) or lymphangiohemangioma (LHA). HLA occurs in multiple anatomical sites, such as the head and neck, axilla, abdominal cavity, extremities, and urinary bladder, but it is infrequent in the oral cavity. An 18-year-old male with a history of abdominal tuberculosis presented with an asymptomatic mandibular gingival swelling that was histologically diagnosed as HLA. A six-month follow-up revealed no recurrence. The observations reported in this case are unusual, and our literature review revealed no previously documented case of gingival HLA.
