title: Plexiform tumorlet: a clinical and pathologic study of 15 cases with ultrastructural observations.
abstract: The morphologic features of 15 uterine plexiform tumorlets are described. Four of the 15 were examined ultrastructurally; all of these showed features of smooth muscle differentiation. Thus, origin from smooth muscle cells is most likely.
