Many cases have been reported pertinent to the kidney under the name of xanthogranulomatous pyelonephritis and in the lung as inflammatory pseudotumor. Several other names have also been given to this condition including xanthomas, fibroxanthomas, histiocytes, sclerosing hemagiomas, pseudotumors, and postinflammatory pseudotumor. In these past reports, there was always a history of chronic supperative infection of the affected organ with a mass found afterward which was nonresponsive to therapy.

The clinical course of this condition is benign. The treatment is removal of the affected tissue. Such therapy usually brings with it a good prognosis.
