Lymphangioma is an abnormal collection of lymphatics that are developmental
ly isolated from the normal lymphatic system. Lymphangioma rarely presents
as a solitary pulmonary lesion. We present a case of solitary pulmonary lym
phangioma and review the literature on its pathogenesis, clinical features,
and radiographic findings. (C) 2001 by The Society of Thoracic Surgeons.
