    2015 15 Fulton Metastatic carcinoma of unknown primary

    Multiple choice question

    Nuclear transcription factors emerged as the best lineage-specific markers and using a panel of immunohistochemical stains for nuclear factors is one of the best strategies in the work-up of metastatic carcinoma of unknown primary.

    Nuclear transcription factors are proteins with unique DNA binding and transcriptional/regulation domains which bind to short-sequence DNA motifs. They serve as molecular ‘switches’ that regulate expression of a series of cell-specific proteins.

    Nuclear transcription factors have advantages as immunohistochemical markers. They are positive on entire tumor cell population. Their expression is  not necessarily related to state of tumor differentiation. They are exquisitely sensitive and specific. Due to nuclear expression the stains are easy to interpret.

    Answers below list useful immunohistochemical markers with corresponding primary cancers they are expected to be expressed in. Please identify one answer which lists cytoplasmic/membraneous rather than nuclear markers.
