NUT midline carcinoma is a super rare tumour.

General

  • Not specific to any tissue type or organ.[1]
  • Defined by mutation in NUT gene.
    • NUT = Nuclear protein in testis.[2]

Clinical:

  • Usually midline - as the name of the tumour suggests.
  • Head, neck and mediastinum.[3]
  • Poor prognosis.

Microscopic

Features:[1][3]

  • Poorly differentiated carcinoma.
    • Cohesive malignant cells.
  • Islands of well-differentiated squamous epithelium - key feature.

DDx:

Molecular

  • Rearrangement of the NUT gene.[1]
    • Most common: t(15;19)(q14;p13) BRD/NUT.[3][4]
