Intravenous pyogenic granuloma of the renal vein: A rare morphological differential diagnosis to renal cell carcinoma

Abstract

We report the fourth case reported world-wide of an intravenous pyogenic granuloma (IVPG) originating from a renal vessel. This rare and benign tumor is mostly found in the head and neck region and has been described very rarely in association with the kidneys. By reviewing the characteristics of all published cases we suggest diagnostic and therapeutic strategies for patients with possible IVPG in the renal vessels out of the view of highly experienced surgeons specialized in advanced Inferior Vena Cava-thrombectomy.

Ultrasonographic features of an intravascular lobular capillary hemangioma originating in the basilic vein: Case report and literature review

“…3,4 In rare cases, ILCH might occur in the renal vein, iliac vein, adrenal gland, and corpus cavernosum of the penis. [5][6][7][8] Epidemiologically, ILCH usually occurs in middle-aged people, with a slight female predominance. 4 Most patients present for the first time with a well-defined, elevated skin mass which may remain stable or grow slowly over several months, as in the present case who presented with a self-palpable gradually enlarging mass.…”
