Adrenal Intravascular Papillary Endothelial Hyperplasia

Abstract

Aim: We describe the rare case of a woman with adrenal intravascular papillary endothelial hyperplasia (IPEH) or Masson's tumor. We present relevant background information on IPEH and our case report, as well as describe a workup and treatment plan for the lesion.

Peripheral nodular enhancement in adrenal and renal hematomas: A report of 3 cases

“…PEH, also known as Masson's tumor, is a reactive process seen in stages of organization and recanalization of a hematoma/hemangioma or any vascular malformation [7] . PEH is benign and is most frequently seen in the skin and integument of the head, neck, and extremities, but may involve any of the visceral organs [8] , [9] , [10] , [11] , [12] , [13] . In the third case, pathology did not show any areas of PEH, but instead very dense peripheral areas of organization comprised of thickened fibromuscular cellular proliferation without atypia or increased mitoses, along with hemosiderin-laden macrophages, and multiple areas of calcification.…”
