ABSTRACT

Lymphangiomas are vascular malformations, known as benign tumors of lymphatic vessels. They are most commonly located in head and neck region whereas oral cavity lesions are rare. The clinical appearance is either clear fluid and blood filled thin walled blisters or smooth flesh-colored papules or nodules varying in size. The condition does not regress itself.Dilated lymphatic vessels lined with endothelium of varying wall thickness is seen on histopathology.

Surgical excision, electrocautery, cryosurgery, radiotherapy, injection of sclerosing agent, CO2 and argon laser are used in treatment and recurrence is common. As a developmental defect lymphangiomas are frequently seen at birth or early childhood period, whereas acquired lymphangioma or lymphangiectasias are structurally and histologically not different from lymphangioma. This condition develops in a previously normal lymphatic vessels and is described following chronic infections as tuberculosis, radiotherapy, cheloid, tumors and recurrent trauma. Thirty six year old female patient with vesicular papules of 9 months history underwent to cryosurgery after the biopsy is compatible with lymphangioma. The lesions are thought to be related to chronic trauma due to deficiency of lower central incisor and dental treatment is offered to patient.
