Magnetic resonance imaging (MRI) showed multiple masses extending from the basal layer of the myometrium to the posterior wall of the uterus (Figure 1).
T1-weighted and T2-weighted images revealed a higher intensity, suggesting the tumor containing internal hemorrhagic components.

T2-weighted images revealed areas of higher intensity, suggesting tumors that could contain internal hemorrhagic components (Figure 2). The endometrium was 5 mm.
Numerous vessels and areas of a perivascular arrangement were observed (Hematoxylin and eosin (HE) stain x100).

Numerous vessels and areas infiltrated by perivascular arrangements were observed (Figure 3).
Immunohistochemistry of the tumor cells showing positive staining for HMB-45 (100x).

Immunohistochemically, the tumor was positive for Human melanin black 45 (HMB-45), alpha- smooth muscle actin (alpha-SMA), and desmin and partially positive for Melan-A (Figure 4).
