Lipoplastic lymphadenopathy simulating malignant lymphoma and pelvic lipomatosis: Report of a case and review of the literature.

The second known cases of pelvic lipoplastic lymphadenopathy is presented. Roentgenographic studies including lymphangiography were instrumental in the diagnostic evaluation but a histopathologic diagnosis was essential to exclude a neoplastic process. The etiology and natural history of this disease are indeterminant but seemed to pursue a benign 17-year course in our patient. A retroperitoneal lymph node dissection is not indicated unless encroachment on adjacent pelvic viscera causes mechanical obstruction.
