Abstract

Skeletal muscle metastasis from pancreatic cancer is rare. We present a 72-year-old female patient with unresectable pancreatic tail cancer. Fifteen months after the introduction of the chemoradiotherapy, an 18-mm elastic hard tumor was found in her right chest wall and resected after confirmation of no other metastatic lesions. Postoperative pathological examination diagnosed it as a muscle metastasis from the pancreatic cancer, and the patient has since been continuing chemotherapy for 10 months. A review of the literature regarding skeletal muscle metastasis from pancreatic cancer is also presented.

Keywords: Muscle metastasis; Operation; Pancreatic cancer.

An enhanced CT revealed a 45-mm tumor in the body of pancreas (a). The SUV (max) of the tumor was 6.2 in a PET-CT (b). After the chemoradiation for 15 months, the size of the primary tumor was reduced to 25 mm (c). The abnormal uptake in a PET-CT disappeared (d)

An enhanced CT scan revealed an 18-mm tumor in the right thoracic wall (a, arrowheads). PET-CT showed FDG uptake of the tumor (b). The tumor existed in the muscle (c, arrowheads) and was resected (d). Postoperative histological examination confirmed the tumor as a muscle metastasis from the pancreatic cancer (e, hematoxylin-eosin staining)
