Histologic features, such as the level of cellular pleomorphism and mitotic activity, can be variable, but they are the most important factors used to distinguish angiosarcoma from benign vascular lesions including IPEH.
Radiologically, IPEH is contrast-enhancing and homogenous on computed tomography (CT) or MRI and might contain microcalcification areas.
Histologically, bundles of papillae with single or several stalks presenting in a dilated vascular space, projecting and even occluding the lumen, are the main features of IPEH.
Clinically, Kaposi sarcoma can be detected in the oral cavity, palate, or tongue as a reddish-brown or blue, flat, vascular lesion, and it may mimic IPEH.
Hemangiomas can be differentiated from IPEH by their lack of endothelial proliferation unless they are secondarily traumatized.
In conclusion, IPEH may clinically and radiologically mimic several other lesions.
The general morphologic features of this present lesion were consistent with a diagnosis of IPEH Within a preexisting vascular lesion.
The exact histogenesis of IPEH is unclear, but it is probably a peculiar morphologic feature of a thrombus undergoing organization.
Clinically, IPEH usually manifests as a firm and sometimes tender mass that imparts a reddish-blue color to the overlying skin or mucous membrane.
Because its clinical signs and symptoms are nonspecific, IPEH, like most other vascular malformations, poses a difficult diagnostic challenge.
Previous studies have shown that some IPEH masses are homogenous on CT and MRI, whereas others are nonhomogenous as well as contrast-enhancing.
Areas of microcalcification have been noted in IPEH lesions.
