Retroperitoneal Lymphangioma Following Pyeloplasty in Child / 대한비뇨기과학회지

ABSTRACT

A lymphangioma is a rare benign congenital tumor of the lymphatic system, resulting from the failure of lymphatic drainage into the venous system, which is due to atresia or the insufficiency of an efferent lymphatic channel. A lymphangioma usually occurs in the neck or axillary region. A retroperitoneal lymphangioma is very rare. Herein, a case of a retroperitoneal lymphangioma incidentally found four months after performing pyeloplasty on a child, is reported.
