Benign lymphangioendothelioma manifested clinically as actinic keratosis.

Benign lymphangioendothelioma is an acquired lymphangiectatic lesion that must be recognized and differentiated from angiosarcoma, early Kaposi's sarcoma, and lymphangioma circumscriptum. We report the case of a 68-year-old woman with the clinical presentation of a possible actinic keratosis and the typical histologic findings of benign lymphangioendothelioma and an overlying actinic keratosis.
