Pyogenic granuloma over the venous component of a mixed vascular malformation

Abstract

A 52‐year‐old man presented with a rapidly growing red tumor on the central neckline. It had appeared over a congenital flat and pinkish vascular lesion that involved the shoulder and the upper anterior area of his chest. Intermingled with the pinkish stain, there were also some blue nodules several millimeters in diameter. Histopathologic examination revealed that the full lesion was a mixed venous‐capillary malformation. The red tumor was excised and diagnosed as a pyogenic granuloma developing over the venous component of the vascular malformation. To our knowledge, a pyogenic granuloma growing over a venous malformation has not been previously described.

An Uncommon Presentation of Pyogenic Granuloma

“…Also, cases of PG have been shown to recur even in different anatomical locations with subsequent pregnancies [15]. The hormonal influence in the development of PG has clearly been stated and PG has been described to occur not rarely in the context of oral contraceptive consumption [16].…”
