Intravascular Papillary Endothelial Hyperplasia (IPEH) or Masson’s Tumor is a benign vascular tumor, most commonly
seen on the skin and usually on the head, neck or extremities. It is more common in women with no age predilection. Visceral
involvement is very rare, with about 30 intra-abdominal reports. We present a case report of a 58 year old woman who
underwent a CT scan due to dysphagia complaints, with an incidental known finding of growth in the adrenal adenoma, which
was 5 cm in diameter on hospitalization. The patient underwent laparoscopic adrenalectomy. Biopsy results demonstrated a
brownish yellow lesion, 2.8 cm in diameter, composed of a blood clot and septate. Immunochemical staining for CD31 and
CD34 was positive and the lesion was diagnosed as an IPEH of pure form. Our review of literature examines different forms
of IPEH, previous reports and characteristics of Masson’s tumors in the adrenal gland and stratifies ways of differentiation
it from other benign or malignant lesions of the adrenal.
