title: Bilateral symmetric gluteal muscle metastases from pancreatic carcinoma presenting as a myositis.
abstract: Skeletal muscle metastases from pancreatic carcinoma are exceedingly rare with only a few cases reported in the published work. The case of a 59-year-old man with bilateral, symmetric gluteal muscle metastases from pancreatic carcinoma is presented. This case was clinically challenging as until skeletal muscle biopsy was carried out, the working diagnosis was that of paraneoplastic polymyositis. A brief review of the published work is also presented.
