title: Smooth muscle differentiation in ovarian granulosa-cell tumours: a new case report.
abstract: Smooth muscle differentiation in stromal ovarian tissue has rarely been described in normal and tumoural ovaries, especially in granulosa-cell tumours. A moderately differentiated adult granulosa-cell tumour in an 83-year-old-woman is reported. Tumoural stroma included clusters of regular smooth muscle cells stained positively for smooth muscle actin. The presence of smooth muscle differentiation in an ovarian granulosa-cell tumour should be taken into consideration during diagnosis.
