Intravascular papillary endothelial hyperplasia is a rare benign vascular lesion of the skin and subcutaneous tissues, characterized by a reactive proliferation of endothelial cells that can present de novo in normal blood vessels (primary intravascular papillary endothelial hyperplasia), but it can also develop from a pre-existing vascular process (type II intravascular papillary endothelial hyperplasia), or it can arise in an extravascular location from a post-traumatic haematoma. The differential diagnosis between intravascular papillary endothelial hyperplasia and malignant vascular tumours can be challenging, due to the lacking of a specific radiologic description. We present a case of intravascular papillary endothelial hyperplasia of the hand radiologically mimicking a hemangiopericytoma.

Masson’S Hemangioma

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.

Intravascular papillary endothelial hyperplasia (IPEH) or so-called Masson hemangioma is a benign nonneoplastic thrombus-associated organizing proliferation. De novo or secondary IPEHs are not uncommon oral lesions. An associated oral phlebolith is uncommon. Oral IPEHs and phleboliths can be diagnostically challenging. Certain histomorphologic features are helpful clues. Immunohistochemistry is a useful confirmatory tool. We present a case of an IPEH with phlebolith in a 37-year-old healthy lady who presented with a nodular lesion of the tongue. Histology showed a calcific nodule associated with an endothelial-lined vascular lesion with histomorphologic and immunohistochemical features of IPEH. The presence of a solitary extruded phlebolith could be challenging for pathologists and could be confused with other oral calculi, particularly sialoliths. The presence of papillary fronds, endothelial-lined minute vascular channels, fibrin thrombi, and hemosiderin pigment on the surface of the calculus points to a calcified thrombus. The lamellated concentric onion ring layers corresponding to Zahn lines around a central calcific nidus is another hint. Phleboliths should be considered by pathologists in their differential diagnosis of oral calculi. Distinction from sialolith is clinically important because the etiology and management are different.

Benign Nature

Intravascular papillary endothelial hyperplasia is a benign nonneoplastic vascular lesion that consists of endothelial cells with abundant vascular tissue with papillary proliferation. An adult female had a painless growing dark red nodule on the left side of the lower lip and often touched and gnawed at it for more than 4 years. The lesion was a tender, smooth mass approximately 1 cm in diameter without discoloration reaction. Magnetic resonance imaging of the lesion showed specific findings. She was diagnosed clinically as having mimicked hemangioma, and the lesion was totally excised under local anesthesia. Histopathological examination revealed that papillary proliferated endothelial cells with venous pool, and the lesion was diagnosed as intravascular papillary endothelial hyperplasia associated with venous pool. There has been no recurrence for more than 1 year. Despite the benign nature of this lesion, it could have been mistaken for a malignant tumor because of its clinical course and radiologic findings.

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.

Papillary Neoplasm

Intravascular papillary endothelial hyperplasia is an exceptional, benign, inflammatory, vascular neoplasm delineating papillary configuration engendered from reactive proliferation of damaged endothelial cells, while being confined to a thrombus. Initially scripted by Pierre Mason in 1923, the tumefaction was denominated as an intra-luminal lesion within an ulcerated, haemorrhoidal vein and designated as “hemangio-endotheliome’ vegetant’ intravasculaire”(1). The neoplasm is additionally nomenclated as Masson’s tumour, Masson’s pseudo-angiosarcoma, endovascularite proliferante thrombopoietique, intravenous atypical vascular proliferation, intravascular angiomatosis, vascular angiomatosis, intravascular endothelial proliferation, reactive papillary endothelial hyperplasia or intravascular papillary endothelial hyperplasia. The papillary neoplasm is associated with deposition of fibrin and thrombotic substances within a painful, ulcerated.

Abstract Intravascular papillary endothelial hyperplasia is a benign intravascular process thought to arise from an organizing thrombus. The lesion may present clinically as an abnormal mass and, depending on the location, may be confused with benign or malignant neoplasms. It has been described in a variety of locations. Involvement of the renal vein by papillary endothelial hyperplasia is extremely rare, with only 4 cases reported in the literature. We describe 2 additional cases. In both cases, the radiologic examination revealed a well-circumscribed mass in the hilar region of the kidney, which was considered to be a renal neoplasm. Nephrectomy specimen in each case revealed characteristic features of intravascular papillary endothelial hyperplasia. It is suggested that intravascular papillary endothelial hyperplasia should be included in the differential diagnosis of a hilar renal mass.

Papillary Endothelial Hyperplasia

Intravascular papillary endothelial hyperplasia (IPEH) is a benign lesion of the skin and mucosa of vascular origin characterized by reactive proliferation of endothelial cells. A 76-year-old woman was referred presenting a painless nodule on the lip. Intraoral examination revealed bluish submucosal nodular proliferation, measuring 10 × 5 × 5 mm, affecting the lower labial mucosa. The lesion had a firm consistency and it was not fixed to the adjacent tissues. The main differential diagnoses were mucocele/mucus retention cyst, sialolith, or salivary gland neoplasia. An incisional biopsy was performed and during the intraoperative procedure an encapsulated red-bluish nodular mass was observed. Microscopic analysis revealed papillary endothelial proliferation in the center of the lesion and fibrin admixed with inflammatory cells in organization peripherally. There was no nuclear atypia, mitotic figures, or necrosis. The endothelial cells were CD34 positive, with low Ki-67 proliferation index (4%). α-SMA highlighted the vessel walls, whereas negativity for D2-40 excluded lymphatic origin. Final diagnosis was IPEH associated with an organizing thrombus. Dentists should be aware about this rare benign vascular lesion, whose final diagnosis is achieved only after histopathology analysis. Surgical removal is the treatment of choice and no recurrence is expected.

Mixed type capillary-cavernous hemangioma is a rare vascular anomaly, with an intranodal localization being extremely rare. Its finding is often accidental but may be clinically symptomatic. The diagnosis relies on histopathology, showing a proliferation of capillaries and cavernous vessels filled with erythrocytes and lined by endothelial cells. Magnetic resonance imaging with enhanced and T2 STIR sequences is the most efficient imaging for diagnosing this type of hemangioma. Rarely, malignancy or another vascular lesion can be evoked as a differential diagnosis of mixed hemangioma. Treatment in this localization is often surgical, even if other possibilities exist for other areas. In this article, we describe a very rare case of intranodal capillary-cavernous hemangioma.

AbstractIntravascular papillary endothelial hyperplasia or Masson's tumor is a rare reactive disease of vascular origin characterized by exuberant proliferation of endothelial cells. Its importance lies in its ability to mimic a variety of diseases, both benign and malignant. Here, we present a unique case of Masson's tumor arising from the abdominal supraceliac aorta in a 32-year-old man initially misdiagnosed as leaking aortic pseudoaneurysm.
