Eosinophilic, solid and cystic renal cell carcinoma, abbreviated ESC-RCC, is recently described, evolving kidney tumour that is presumed to be malignant.[1]

It is not within the WHO 2016 classification of renal neoplasia.

General

Gross

Features:[1]

  • Tan colour.
  • Solid and usually cystic.

Microscopic

Features:[1]

  • Epithelioid cells with abundant stippled eosinophilic cytoplasm +/- peripheral clearing.
  • Round nuclei with one prominent nucleolus.
  • Nested or solid architecture +/- cystic spaces with hobnail lining cells.
  • +/-Scattered histiocytes (common).
  • +/-Multi-nucleation (common).
  • +/-Small intracytoplasmic globules - usually seen but only present in a handful of cells.
