Intravascular papillary endothelial hyperplasia or Masson's hemangioma is a rare vascular tumor. The reactive proliferation of endothelial cells in this disease mimics other benign or malignant vascular proliferation such as angiosarcoma or Kaposi's sarcoma. It is important to make an accurate distinction to avoid confusion with these malignant tumors. This would facilitate a proper diagnosis, which is essential so that the patient is not subjected to unnecessarily aggressive or inappropriate treatment.

Intravascular papillary endothelial hyperplasia (IPEH, Masson's hemangioma) is a non neoplastic reactive endothelial proliferation most commonly located in the skin or subcutaneous tissues although it has been reported in multiple locations throughout the body. This lesion may arise from malformed or normal vessels primarily, and may develop with hemangioma, pyogenic granuloma, or lymphangioma. This lesion, though benign, is clinically important since it may present as a mass and be confused histologically with angiosarcoma. The authors report a 27 years old patient with a mass in his forearm which results in intravascular papillary endothelial hyperplasia.

Intravascular papillary endothelial hyperplasia (IPEH) known as Masson's hemangioma is a rare benign reactive vascular lesion caused by the abnormal proliferation of endothelial cells. The lesion occurs most commonly in the fingers, head and neck, but very rare in the foot. We report a case of IPEH in the foot treated with operative excision.

Intravascular papillary endothelial hyperplasia (IPEH) has appeared in the literature under a variety of names, including Masson's tumor, Masson's hemangioma, and Masson's pseudoangiosarcoma. It is a benign lesion of the skin and subcutaneous tissue characterized by reactive proliferation of vascular endothelial cells with papillary formations. The clinical picture is not specific and the lesion resembles malignant angiosarcoma clinically and histopathologically. Therefore, it is often mistaken for angiosarcoma and a group of other benign and malignant vascular lesions. We report on a case of IPEH adherent to peripheral nerve treated with operative excision.

Hemangioma is the most common benign tumor in neonatal and infant stage. In the head and neck region, the lesion mostly occurs in the masseter, trapezoidal or sternocleidomastoid muscle. Due to its rarity and non-specific symptoms, it is difficult to diagnose precisely. Intramuscular hemangioma can be misdiagnosed as sialolithiasis of the parotid gland. There are several treatment options for hemangiomas such as sclerotherapy, radiotherapy, embolization, and surgery. Of all these, definitive surgical resection is considered most effective in preventing future recurrence. Here we report a case of intramuscular hemangioma that was detected in the patient's right masseter muscle which was initially misdiagnosed as parotid sialolithiasis and was consequently managed with surgical resection.
