title: Ultrastructure of an endometrial stromal nodule with skeletal muscle.
abstract: The ultrastructural appearance of an endometrial stromal nodule with prominent smooth and skeletal muscle differentiation is described. This is the first reported case of endometrial stromal nodule with a heterologous skeletal muscle component and emphasizes the value of electron microscopy and its correlation with immunohistochemistry in the study of rare or complex lesions.
