The histiocytoid hemangiomas and other controversies.

We have reviewed the clinicopathologic features of Kimura's disease, angiolymphoid hyperplasia with eosinophilia, epithelioid hemangioma of the testis, epithelioid hemangioendothelioma, spindle cell hemangioendothelioma, malignant endovascular papillary angioendothelioma of childhood (Dabska's tumor), epithelioid angiosarcoma, angioblastoma of Nakagawa, bacillary angiomatosis, verruga peruana, and other inflammatory angiomatoses. On the basis of our experience and reading of the literature, we conclude that angiolymphoid hyperplasia with eosinophilia, histiocytoid hemangioma of the testis, epithelioid hemangioendothelioma, and probably spindle cell hemangioendothelioma, constitute a group of related conditions best called the histiocytoid hemangiomas. Kimura's disease, Dabska's angioendothelioma, epithelioid angiosarcoma, and the inflammatory angiomatoses are not histiocytoid hemangiomas. Angioblastoma of Nakagawa is not related to lobular capillary hemangioma (pyogenic granuloma).
