AB Carcinoma  of  unknown  primary  (CUP)  is  a  biopsy-proven  malignancy  for  which  the  anatomic  site  of  origin  remains  unidentified  after  an  intensive  search.  CUP  is  one  of  the  10  most  frequently  diagnosed  cancers  worldwide,  accounting  for  3–5%  of  all  cancers.  Most  investigators  limit  CUP  to  epithelial  cancers  and  do  not  include  lymphomas,  metastatic  melanomas,  and  metastatic  sarcomas  because  these  cancers  have  specific  histology-  and  stage-based  treatments  that  guide  management.
