Oral lymphangiectasias and Crohn's disease: two case reports.

Lymphangiectasias, or acquired lymphangiomas, are rare in the oral cavity, more typically occurring on the skin or the genital area and, to our knowledge, have not been reported previously in association with Crohn's disease. Lymphangiectasias can occur at any age and develop secondary to chronic obstruction of the lymphatics. This differentiates them from congenital lymphangiomas, which are congenital malformations of the lymphatic system. We present 2 cases of oral lymphangiectasias associated with Crohn's disease, one of which was treated successfully with cryotherapy.
