Intravascular papillary endothelial hyperplasia of the finger: a case of Masson’s tumor

Masson’s tumor or Masson’s hemangioma, more precisely termed intravascular papillary endothelial hyperplasia (IPEH), is an uncommon benign vascular lesion of the skin and subcutaneous tissues which can be frequently confused with angiosarcoma. Although relatively rare, its accurate diagnosis is essential since it can clinically be similar to both benign and malignant lesions. We present a 39-year-old man with a round bulging arising from the left palm side of the hand with gradual growth in the last 5 months and on and off tenderness. The microscopic section demonstrated the papillary proliferation of endothelial cells in favor of Masson’s hemangioma, which was sufficiently treated with excision alone.

Papillary Endothelial Hyperplasia

Intracranial intravascular papillary endothelial hyperplasia (IPEH), also referred to as Masson’s tumor, is a condition that rarely occurs in the nervous system. IPEH most frequently occurs extracranially in the skin of the face, skull, neck, and trunk and can easily be mistaken clinically, radiologically, and histologically for angiosarcoma, organizing hematoma, or other vascular malformations. IPEH accounts for roughly 2% of all vascular tumors and is extremely rare intracranially, with only 23 reported cases compared with more than 300 cases of IPEH occurring in the skin and subcutaneous tissue. To date, it has never been reported to occur in the pineal region. The authors report the case of a patient with an IPEH in the pineal region who underwent complex resection and experienced reversal of neurological symptoms.

Masson’s tumor, also known as intravascular papillary endothelial hyperplasia (IPEH), is a rare, benign vascular tumor characterized by the proliferation of endothelial cells with papillary formations. Differential diagnosis between IPEH and angiosarcoma is important because both have microscopic similarity. Herein, we report a rare case of IPEH on the right lateral neck of a 50-year-old female presenting with a neck mass, which was completely removed without complication.
