@entity3 of the hand are rare and metastases to the skeletal muscle from the gastrointestinal system are even much rare. Here we present a case of metastatic @entity420 to the thenar muscle, which is the first report of thenar muscle @entity3 from @entity420 with @entity876 mutation. To date, only two other cases of thenar muscle @entity3 have been documented, one is from squamous cell @entity2 and the other is from @entity189 . The present 67-year-old Chinese @entity1 of poorly differentiated @entity420 of the ileocecal region developed @entity189 in the right thenar eminence, which presented with swelling and @entity158 . Magnetic resonance imaging of the right hand revealed a well-defined enhanced mass in the right thenar muscle. It was proved to be metastatic @entity420 using core needle biopsy, which was supported to be gastrointestinal origination by positive immunoreaction with @entity6628 . Positive immunoreaction with @entity876 protein indicated the poor prognosis of the @entity1 . Further systemic evaluation including computerized tomography scans revealed extensive metastases to liver, right kidney, right abdominal wall, left axillary and right subclavicular lymph nodes, and skin of the right thigh. Treatment was given with palliative systemic chemotherapy. After 8 cycles of chemotherapy, the swelling and @entity158 of the right thenar were ameliorated, and the @entity1 regained full use of his right hand and his quality of life was improved. The @entity1 died of liver @entity3 9 months after the diagnosis of the right thenar @entity3 . In conclusion, here we display a case of thenar skeletal muscle @entity3 from @entity876 mutated @entity420 , who survived 9 months after diagnosis of the rare @entity3 . If an oncological @entity1 presents an intramuscular mass, muscle @entity3 must be included in the differential diagnosis. Metastatic hand @entity5 generally indicate systemic spread, so the treatment is usually palliative and the prognosis is poor. The primary objective of treatment is improvement of the @entity1 's quality of life.
