title: An elderly patient with gastric carcinoma developing multiple metastasis in skeletal muscle.
abstract: We present a 70-year-old man with gastric carcinoma developing multiple metastasis in skeletal muscle. He had a right supraclavicular lymph node swelling. Brain, chest and abdomen CT scans revealed metastatic lesions in the brain, lung, liver and bilateral adrenal glands. Further, CT showed a ring enhanced soft-tissue mass in the left lumbar muscle. Needle aspirate of the mass in both the left lumbar muscle and the right enlarged supraclavicular lymph node revealed cells suggestive of poorly differentiated adenocarcinoma. Upper gastrointestinal endoscopic evaluation demonstrated an advanced gastric carcinoma. Two months after admission, the tumor in the left lumbar muscle had grown and some new lesions in the left iliopsoas muscles appeared. Intramuscular metastasis from gastric carcinoma is an extremely rare phenomenon.
