title: Unusual manifestations of soft tissue metastasis.
abstract: We present a patient with pulmonary adenocarcinoma metastatic to the left forearm. The magnetic resonance imaging (MRI) revealed no discrete tumor, but an infiltrative signal change of the subcutaneous tissue and muscle. The lymphatic invasion by cancer cells explains this unusual manifestation of image findings.
