Histopathologic classification of lymphangioma is as follows: (A) lymphangioma simplex, small thin-walled lymphatic vessels; (B) cavernous lymphangioma, dilated lymphatic vessels with surrounding adventitia; (C) cystic lymphangioma, large lymphatic spaces surrounded by fibrovascular tissue; and (D) benign lymphangioendothelioma, lymphatic channels separated by collagen bundles (2).
Benign lymphangioendothelioma (acquired progressive lymphangioma), lymphatic channels appear to be dissecting through dense collagenic bundles.
Some resemble benign lymphangioendothelioma (Figure 10, A), others lymphangioma circumscriptum (Figure 10, B), and some have features of both.
