A red, often ulcerated, boggy papule that represents a hyperplasia of small cutaneous vessels which are "fed" by an arteriole in the subcutaneous fat, the lesion resulting consistently from external trauma, usually in the form of a puncture or a yank of a "hang nail." In time, the proliferation of vessels ceases, there is progressive fibroplasia, and the then gray or white papule shrinks and eventually disappears.
