Pancreatic metastasis of leiomyosarcoma in the right thigh: A case report

Figure 1 Radiological findings. A: Gadolinium-enhanced T1 weighted image showing a soft tissue tumor in the muscle of the anterior thigh; B: Contrast-enhanced abdominal CT scan showing a heterogeneously enhanced mass at the head of the pancreas; C: Gadolinium-enhanced T1 weighted image showing a well-enhanced mass with necrotic foci at the head of the pancreas; D: Follow-up CT obtained after 10 mo showing a low attenuated mass in the tail of the pancreas.

Figure 2 Gross and microscopic findings for metastatic leiomyo-sarcoma. A: The section reveals a whitish solid tumor with a lobulated pattern and a yellowish necrotic portion, abutting duodenal wall on the left side, and compressed pancreatic head tissue on the right side; B: Low-power view displaying eosinophilic intersecting fascicles circumscribed by a fibrous capsule (a) and adjacent normal pancreatic tissue (b) (hematoxylin and eosin stain ×40); C: Cellular proliferation of atypical spindle tumor cells is accompanied by nuclear atypia and hyperchromasia (hematoxylin and eosin stain × 200); D: Tumor cells show immunoreactivity for desmin.
