Abstract

Intravenous pyogenic granuloma is a rare form of lobular capillary hemangioma and typically consists of an intraluminal polyp attached to the wall of a vein by a fibro-vascular stalk. It rarely occurs in the finger and its character is not enough to diagnosis clinically. Therefore, we report intravenous pyogenic granuloma which occurs in dorsal side of mid-phalanx with magnetic resonance imaging and pathological findings.

  Fig. 1. (A) Preoperative photogragh shows 1.5×0.5 cm palpable mass on the midphalanx level dorsal side of the fourth finger, left hand. (B) Intraoperative photogragh shows 1.6×0.6 cm sized well-lobulated pale mass like region in the vessel of mid phalanx dorsal side.

  Fig. 2. Magnetic resonance imaging. (A) Axial view T1-weighted image shows that the signal of the lesion is equivalent to that of adjacent skin. (B) Axial view T2-weighted image shows 1.2×0.4×0.7 cm-sized well-defined lobulating well-enhancing nodule at the subcutaneous layer of the middle phalanx level. (C) Axial and sagittal view T1-weighted image obtained after intravenous injection of gadolinium shows homogeneous enhancement of lesion.

  Fig. 3. Histological photograph (H&E). (A) Subcutaneous nodule showing an intravenous polyp composed of lobules of capillaries separated by fibrous connective tissue attached to the wall of the vein by a fibrovascular stalk (×40). (B) Higher magnification shows monotonous endothelial hyperplasia and capillary proliferation (×200).
