Renal tumour with t(6;11) translocation, also t(6;11) renal cell carcinoma, is a rare kidney tumour seen primarily in children.

It also known as TFEB RCC.[1]

General

  • Very rare - approximately 2 dozen reported cases as of 2014.[1][2]
  • Lymph node metastases are common.
  • Traditionally thought of as a pediatric tumour... but cases in adults are reported.[1][3]

Microscopic

Features:

  • Hyaline material between nests.
  • Large cells with clear to eosinophilic cytoplasm.

IHC

Molecular

  • t(6;11)(p21;q12) MALAT1[4]/TFEB.[5]
