SMARCB1-deficient renal medullary carcinoma is a rare malignant kidney tumour associated with sickle cell trait and a poor prognosis.

SMARCB1-deficient renal medullary carcinoma
Diagnosis in short

Renal medullary carcinoma (right of image), reactive urothelium and sickled red blood cells. H&E stain. (WC/Nephron)
LM variable architecture (reticular - resembling a net, adenoid cystic carcinoma-like, yolk sac tumour-like), desmoplastic stroma (usu. prominent), drepanocytes (sickled red blood cells)
LM DDx collecting duct carcinoma, yolk sac tumour, hereditary leiomyomatosis and renal cell carcinoma syndrome-associated renal cell carcinoma, ALK translocation renal cell carcinoma
IHC SMARCB1 (INI1) -ve, PAX8 +ve, cyclin D1 +ve, CK7 +ve, vimentin +ve, EMA +ve
Gross well-circumscribed mass in renal medulla
Grossing notes total nephrectomy for tumour grossing, partial nephrectomy grossing
Staging kidney cancer staging
Site kidney, medulla - see kidney tumours
Associated Dx sickle cell disease or sickle cell trait
Clinical history usu. young adults with sickle cell disease or sickle cell trait
Prevalence rare
Radiology muscle hypertrophy (due to exercise)
Prognosis poor
Clin. DDx other renal tumours

It was previously called renal medullary carcinoma, abbreviated RMC.

General

  • Rare.
  • Usually young adults.
  • Strong association with sickle cell trait (heterozygotes for the sickle cell allele)[1] and sickle cell disease.[2]
    • A large series (217 cases) showed 88% (191/217) have sickle cell trait and 8% (16/217) have sickle cell disease.[3]
  • Aggressive/poor prognosis.[4]
  • Closely related to collecting duct carcinoma.[5]
  • Associated with high-intensity exercise.[6]

Aside:

Note:

Gross

Features:[4]

  • Well circumscribed.
  • Renal medulla.

Imaging

  • Increase muscle surface area (muscle hypertrophy) - due to exercise.[6]

Microscopic

Features:[1][4]

  • Variable architecture:
    • Reticular (resembling a net) - classic.
    • Adenoid cystic carcinoma-like appearance:
      • Cystic spaces.
    • Yolk sac-like.
    • Tubular.
  • Desmoplastic stroma - prominent.
  • Inflammation:
    • Lymphocytes.
    • Neutrophils - margination in vessels.
  • +/-Drepanocytes (sickled red blood cells) - especially among extravascular red blood cells.

IHC

Features:[2]

  • SMARCB1 (INI1) -ve.[10]
  • Vimentin +ve.
  • EMA +ve.
  • CAM5.2 +ve.
  • AE1/AE3 +ve.
  • Cyclin D1 +ve.[5]

A panel:

  • AE1/AE3, cyclin D1, CK7, PAX8, p63, INI-1, L-ALK, RCC, CKIT, AMACR, GATA3, CK34betaE12, CK5/6, vimentin.
