title: Ultrastructure of myofibroblasts and decidualized cells in leiomyomatosis peritonealis disseminata.
abstract: A case of leiomyomatosis peritonealis disseminata studied by light and transmission electron microscopy is reported. The lesion, from a pregnant woman, was found to contain predominantly myofibroblasts and decidualized cells in a rich collagen stroma, while relatively few leiomyocytes and fibroblasts were observed. The development and fate of this entity are discussed in view of the present findings and those previously reported.
