Figure 2. (a) Axial T1-weighted magnetic resonance imaging (MRI) of the tumor in the left labia majora revealed marginally higher signal intensity in the peripheral region and partially intermediate signal intensity in the central region than that in the surrounding muscle (arrows). (b) T2-weighted image revealed high signal intensity in the peripheral region and marked high signal intensity in the central region (arrows).

Figure 3. Photomicrograph. The tumor is composed of spindle cells without nuclear atypia and fibrous stroma forming hemangiopericytomatous pattern (a) Hematoxylin and eosin stain (× 200). The tumor cells are focally positive for CD34 (b) and strongly positive for STAT6 (c) (× 200 immunohistochemical staining).
