Synonyms

This tumor was previously named “multilocular cystic renal cell carcinoma.”

Definition

Multicystic tumor with septa containing individual or groups of clear cells with ISUP/WHO 2016 low nucleolar grade (1–2).

Clinical Features

  • Incidence

    This tumor accounts for less than 1% of all renal tumors, usually incidentally discovered.

  • Age

    It occurs in middle-age adults.

  • Sex

    There is no difference between male and female.

  • Site

    There is no site predilection.

  • Treatment

    Partial or radical nephrectomy is the surgical treatment of choice.

  • Outcome

    To date there are no evidence of recurrence or metastasis.

Macroscopy

The tumor consists exclusively of variably sized cysts separated by thin septa and filled with clear, serous, or gelatinous fluid (Fig. 1). Solid, grossly discernible tumor mural nodules are incompatible with the diagnosis.
