NUT carcinoma
Diagnosis in short

NUT carcinoma. H&E stain.
Synonyms NUT midline carcinoma, carcinoma with t(15;19) translocation
LM cohesive malignant cells (poorly differentiated carcinoma), islands of well-differentiated squamous epithelium
LM DDx Carcinoma ex pleomorphic adenoma, poorly differentiated carcinoma
IHC p63 +ve, CD34 +ve/-ve, EMA +ve
Molecular t(15;19)
Site head and neck, mediastinum, usu. midline
Prevalence very rare
Prognosis very poor

NUT carcinoma is a rare tumour of the head and neck. The WHO calls this tumour carcinoma with t(15;19) translocation.[1] It is also known as NUT midline carcinoma, abbreviated NMC.

General

  • Not specific to any tissue type or organ.[2]
  • Defined by mutation in NUT gene on chromosome 15.
    • NUT = Nuclear protein in testis.[3]

Clinical:

  • Usually midline - as the name of the tumour suggests.
    • Case report of a NMC in the parotid gland.[4]
  • Head, neck and mediastinum.[5]
  • Very poor prognosis.[4]

Microscopic

Features:[2][5]

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

DDx:

Images

  • NUT midline carcinoma - high mag. (WC)

  • NUT midline carcinoma - very high mag. (WC)

Molecular

  • Rearrangement of the NUT gene.[2]
    • Most common: t(15;19)(q13;p13.1) BRD4/NUT.[8]
      • One source suggests it is: t(15;19)(q14;p13.1).[5]
