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).
