This lesion was thought to fall in the spectrum between glomus tumors and capillary hemangioma
and hence the term hemangiopericytoma was chosen.
The main differential diagnoses of nasal masses with similar MRI/CT findings as schwannoma include nasal polyp, malignant peripheral nerve sheath tumors (MPNST), myxoma & fibromyxoma, Lobular Capillary hemangioma
(LCH) and sarcoma.
Tufted angioma has been described in the literature under different names including Nakagawa's angioma, Nakagawa's angioblastoma, progressive capillary hemangioma
, and acquired tufted angioma of the skin and subcutaneous tissue.2 It is a rare, benign vascular tumour occurring most commonly in prepubertal children.3 A few cases occurring at unusual sites like oral mucosa in adults have been reported.4 The lesion of TA enlarges slowly over 5 months to 10 years after which no further growth occurs.
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.
Recently, a vascular-type AVL resembling capillary hemangioma
has been reported.
Pyogenic granuloma (lobular capillary hemangioma
) is a benign, exophytic, vascular tumor, described in 1897 by Poncet and Dor as botryomycosis hominis.
The immature form of capillary hemangioma
known as juvenile hemangioma, (12) is occasionally associated with extensive and life threatening growth.

Splenic hamartoma and capillary hemangioma

(27) The histological differential diagnosis of CHB includes metastatic clear cell renal cell carcinoma (CRCC), paraganglioma, angiomatous meningioma, (28) and capillary hemangioma
. The histological distinction of CHB from metastatic CRCC has long been recognized as a particular difficulty because of striking morphologic similarities between them.
