TFE3-rearranged renal cell carcinoma is a rare type of renal cell carcinoma recognized by the WHO classification as a distinct entity.[1]

It was previously known as renal tumour with Xp11.2 translocation, also Xp11.2 translocation carcinoma and Xp11 translocation renal cell carcinoma. It was previously lumped with other entities in the category MiT family translocation renal cell carcinoma.

It should not be confused with TFEB-rearranged RCC, another translocation carcinoma found in the kidney.

General

  • Defined by the presence of a fusion gene formed with TFE3 @ Xp11.2.
  • TFE3 is the gene involved in the translocation seen in alveolar soft part sarcoma (ASPS).
  • Poor prognosis - majority Stage III or Stage IV.[2]
  • ~1/3 of childhood RCC.[3]

Microscopic

Features:[4]

  • Large cells.
  • Clear or eosinophilic cytoplasm.
  • Papillae or nests.
  • Psammoma bodies - common.[5]
    • Calcification is considered the classic histomorphologic feature.
  • Hyaline bodies - common.

Notes:

Case 2

  • TCK - low mag.

IHC

Key stains - as per ISUP:[7]

  • TFE3 +ve (nucleus).[4] ‡
  • TFEB +ve.
  • Cathepsin K +ve.[8]

Others:

  • CD10 +ve.
  • Vimentin +ve.
  • CK7 -ve.
    • Positive in ~20% of cases.[9]
  • HMB-45 -ve.
  • Melan A -ve/+ve.[10]
    • Should exclude adrenal if +ve.
  • EMA usually -ve.[11]
  • CD117 -ve (0 +ve/21 cases[11]).
  • CK (pooled) -ve.[11] (???)
  • WT1 -ve (0 +ve/21 cases[11]).
  • PAX8 +ve (16 +ve/21[11]).

Notes:

  • Poor man's panel - if one doesn't have the more informative stains:
    • CK (pooled), EMA, Melan A, HMB-45, CK7, AMACR, CD10, vimentin, RCC.
  • ‡ The IHC (in comparsion to FISH) has both false negatives and false positives; in one study by Qu et al. the false positive rate was 7% (2/30) and false negative rate was 4% (2/46).[12]

Molecular

  • Translocation involving TFE3.[4]
    • A very low list of partners have been described.

The most common are:[13]
