case_images: The overlying skin appeared normal without ulceration (Figure 1), and there was no inguinal lymphadenopathy.
case_images: Computed tomography depicted a solid tumor with heterogeneous contrast enhancement (arrowheads) in the adipose tissue.

case_images: Computed tomography depicted a solid tumor with heterogeneous contrast enhancement in the adipose tissue, and no metastases to the liver and lung (Figure 2).
case_images: The tumor comprised spindle-shaped cells with high cellularity in parts (hematoxylin-and-eosin; original magnification, x 100).

case_images: Routine histological examination with hematoxylin-and-eosin revealed that the tumor comprised spindle-shaped cells with high cellularity in parts (Figure 3) and two mitoses per 10 high-power fields.
case_images: Spindle-shaped cells showing strong immunoreactivity for desmin in the cytoplasm (Desmin immunohistochemistry; original magnification, x 400).

case_images: As the tumor cells showed only immunoreactivity for desmin (Figure 4) and alpha-smooth muscle actin, a diagnosis of leiomyosarcoma of subcutaneous adipose tissue origin was confirmed.
