“…Intravenous pyogenic granulomas are rare, benign, intravascular tumors. They occur mostly in the neck and upper extremities 1,2 . Microscopically, they are characterized by a lobular proliferation of capillaries, similar to the more common cutaneous pyogenic granulomas, but they differ by their confinement within the lumen of a vein and by the sparse inflammatory cell infiltrate.…”

A 43‐year‐old man presented with a 1‐month history of a nodule on the left side of the neck. There were no subjective symptoms. He denied any history of trauma. On physical examination, a round, soft, and movable subcutaneous nodule, approximately 1 cm in size, was detected. The overlying skin was normal. The nodule was observed to be attached to the wall of the external jugular vein during biopsy. On histopathologic examination, attachment to the external jugular vein was noted to be via a fibrovascular stalk ( Fig. 1a), and a lobular proliferation of capillaries, some of which were embedded in a fibromyxoid stroma, was observed ( Fig. 1b). There were no atypical cells, and a sparse inflammatory cell infiltrate was seen. The endothelial cells of the capillaries were CD31 positive ( Fig. 1c). 1 (a) Nodule attached to the wall of the vein (hematoxylin and eosin, × 10). (b) A lobular proliferation of capillaries, some of which are embedded in a fibromyxoid stroma (hematoxylin and eosin, × 40). (c) CD31 positivity (× 200)

“…In 1979, Cooper et al 2 described 18 cases of a previously unrecognized entity that they termed intravenous pyogenic granulomas occupying veins of the neck and upper extremities. Since that, fewer than 30 cases with similar lesion were reported and all were located in the neck, arms, forearms, wrists, and hands, 3–6 except 1 in the occular adnexa 7 . The characteristic histopathologic feature of the intravenous pyogenic granuloma is an intraluminal polyp comprising lobules of capillaries lined by flattened or rounded endothelial cells 2 .…”

“…The so‐called intravenous pyogenic granuloma is an intravascular counter part of the pyogenic granuloma, which is first reported by Cooper et al in 1979 2 . Intravenous pyogenic granuloma is a rare benign intravascular tumor that usually occurs in veins of the neck and upper extremities 2–7 . Such a variant arising within another hemangioma is extremely rare and only two case reports can be found in English literature 8,9 .…”
