Definition

Tubulocystic carcinoma is an uncommon multicystic renal cell tumor.

Clinical Features

  • Incidence

    The tumor comprises less than 1% of all renal carcinomas.

  • Age

    Tubulocystic carcinoma occurs most commonly in the fifth and sixth decades of life.

  • Sex

    There is a male predominance.

  • Site

    There is no site predilection.

  • Treatment

    Radical nephrectomy is generally recommended, but partial nephrectomy may be performed for small tumors located in the superficial renal cortex.

  • Outcome

    They usually display an indolent behavior with a few cases with metastasis or recurrence.

Macroscopy

The tumors are solitary well-circumscribed multicystic renal mass. They are frequently 4 cm or less and composed of multiple small- to intermediate-sized cysts and have a white and sponge-like cut surface.

Microscopy

The cysts above described are lined by a single layer of flattened, cuboidal, and hobnailed eosinophilic renal cells with enlarged nuclei with prominent (ISUP/WHO 2016 grade 3) nucleoli (Fig. 1)....
