Intravenous pyogenic granuloma of the finger

Abstract

Intravenous pyogenic granuloma is a rare solitary form of lobular capillary hemangioma that usually occurs in the veins of the neck and upper extremities. We report two cases of intravenous pyogenic granuloma localized in the finger, giving details of the magnetic resonance imaging (MRI) findings. These two cases had similar locations in fingers and identical MRI findings. The differential diagnoses of this rare entity are also discussed.

Subungual Tumors: Clinicopathologic Correlation with US and MR Imaging Findings

“…Lobular capillary hemangioma is often related to a history of prior trauma. However, its clinical manifestations are not sufficiently characteristic to suggest the diagnosis; hence, up to 18% of lesions may be misdiagnosed (25)(26)(27)(28).…”

“…Color Doppler US shows prominent vascularity of the tumor, with an arterial waveform of the internal blood flow (26). At MR imaging, the lesion is isointense on T1-weighted images and hyperintense on T2-weighted images, with marked enhancement after contrast material injection (27,28).…”

An Atypical Site of Vascular Tumor: IVPG of Right Renal Vein

“…The clinical picture of the IVPG is highly nonspecific and insufficient to make a precise diagnosis [3,5,11]. There are no known associated risk factors and the nature of the lesion remains obscure [10].…”

“…The hemangiothelioma has an intermediate position between well differentiated hemangioma and anaplastic angiosarcoma. Finally intravascular papillary endothelial hyperplasia can be distinguished from intravenous pyogenic granuloma by its papillary architecture, presence of hemosiderin deposits and association with organized thrombi [2,5,6].…”

“…It was first described in 1979 by Cooper et al and a most recent review found less than 30 cases reported in literature until now [2][3][4]. IVPG has been seen in patients from 15 to 66 years of age (average 38 years) and with a slight female predominance [5]. These lesions are commonly thought to arise in upper extremities and in neck and head veins [6,7].…”
