TFEB-rearranged renal cell carcinoma, also TFEB RCC, is a rare renal cell carcinoma recognized by the WHO classification.[1][2]

It was previously known as renal tumour with t(6;11) translocation, also t(6;11) renal cell carcinoma. It was first described in children.

It was added to WHO classification of renal neoplasia in the 2012 Vancouver modification.[3]

This entity should not be confused with ELOC-mutated renal cell carcinoma (previously known as TCEB1-mutated renal cell carcinoma).

General

  • Very rare - approximately 2 dozen reported cases as of 2014.[2][4]
  • Lymph node metastases are common.
  • Traditionally thought of as a pediatric tumour... but cases in adults are reported.[2][5]

Microscopic

Features:[6]

  • Solid with occasional rosette-like structures.
  • Two cell populations:
    1. Large epithelioid cells with clear to eosinophilic cytoplasm.
    2. Small lymphocyte-like cells.

  • Cathepsin K +ve.[citation needed]
  • PD-L1 +ve.[10]

Note:

  • Melan A and HMB-45 are considered a good screen for this entity and recommended for renal tumour with eosinophilic cytoplasm.

Molecular


Others translocations involving TFEB have been described:[10]

  • ACTB-TFEB.
  • NEAT1-TFEB.
