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.

of the spinal cord: reports of four cases.
In the literature, although some controversial findings were reported, (11) most studies were unable to detect HHV-8 DNA in mesenchymal and vascular tumors other than Kaposi sarcoma, including hemangiomas, hemangioendotheliomas, infantile capillary hemangioma
, and hemangiosarcoma.
Two cases (16.67%) of capillary hemangioma
were reported, both in young girls; one of them occurred in the nasal septum and the other in the nasal cavity.
(6) Since it is generally accepted that the capillary and small-vessel network in sensory ganglia are precursors of capillary hemangioma
, the presence of a large meatal ganglion in 12% of temporal bones may be responsible for the development of facial nerve hemangioma within the internal auditory canal.
Because of its histologic similarity to other vascular lesions, the differential diagnosis may include cavernous and capillary hemangioma
, (8) bacillary angiomatosis, (9) and other rare vascular lesions.

Tufted angioma were described in the literature under different names including Nakagawa's angioma, Nakagawa's angio blastoma, progressive capillary hemangioma
and acquired tufted angioma of the skin and subcutaneous tissue.
The differential diagnosis clinically includes any polypoid mass, while histologically it includes sinonasal tract polyps, lobular capillary hemangioma
, and other mesenchymal lesions.
One of the rare primary cardiac tumors, hemangiomas are vascular tumors composed of blood vessels that can be either capillaries (capillary hemangioma
) or large cavernous vascular channels (cavernous hemangioma).
(6) In children, the most common manifestation is capillary hemangioma
, whereas in adults the cavernous variation is more frequent.
Adjacent to areas resembling juvenile capillary hemangioma
were epithelioid endothelial cells in glomeruloid configurations (Figure 2).
An excisional biopsy of the intranasal mass was obtained, and pathologic examination revealed the specimen to be a benign capillary hemangioma
. The maxillary antrostomy healed well, and the patient experienced no further nasal bleeding.
"Juvenile hemangioma" is well recognized as only a clinical term, since a capillary hemangioma
can occur in a juvenile setting, as can a cavernous hemangioma.
