title: The ultrastructure of a keloid.
abstract: An active, symptomatic keloid from a 57-year-old woman was examined by both light and electron microscopy. The lesion was found to be comprised entirely of myofibroblasts. Fibroblasts in keloids can apparently undergo full transition to this smooth muscle-like cell.
