a benign tumor of the blood vessels. Hemangiomas generally arise in early childhood from congenital redundant vascular rudiments. Hereditary and hormonal factors also play a part in the formation of hemangiomas, which are found most often in women and children. Hemangiomas of the cutaneous tissues are most common, but they sometimes spread to the underlying organs, passing from the skin to the mucous membrane and impairing the function of organs and tissues. They may also affect muscles and tendons, bone, and internal organs (most frequently the liver). Superficial hemangiomas look like pinkish red or purplish blue strawberry marks. Hemangiomas may ulcerate and bleed. Treatment involves surgery or removal by chemical, thermal, or radiation therapy.

The difficulty tends to lie not in distinguishing glomangiopericytoma from sarcomas, as the latter are usually clearly malignant, but rather in differentiating them from other benign/borderline vascular-rich spindle cell lesions, most commonly, lobular capillary hemangioma (pyogenic granuloma), SFT, leiomyoma, and angiofibroma.
Pyogenic granuloma (lobular capillary hemangioma) is a benign, exophytic, vascular tumor, described in 1897 by Poncet and Dor as botryomycosis hominis.
The term pyogenic granuloma is a misnomer and lobular capillary hemangioma is the preferred term.1 It occurs on skin and mucosal surfaces of upper aero-digestive tract but has also been reported to occur in gut burn scars and intravenously.23 PG has no malignant potential but recurrence is quite common after excision.4 The etiology of PG is not fully understood.
The differential diagnosis of this lesion includes fibrous histiocytoma, Malignant fibrous histocytoma, synovial sarcoma, other stromal sarcomas, juxtaglomerular tumor, vascular leiomyoma, juvenile hemangioma and lobular capillary hemangioma. The treatment of hemangiopericytoma is dependent on the amount of cellular dysplasia and mitotic activity.
The differential diagnosis clinically includes any polypoid mass, while histologically it includes sinonasal tract polyps, lobular capillary hemangioma, and other mesenchymal lesions.
Other lesions that should be considered in the differential diagnosis include a cavernous hemangioma, a papillary endothelial hyperplasia, a disseminated lobular capillary hemangioma, and epithelioid anglomatosis.
