Rethinking about tubulocystic carcinoma of the kidney after taking into account the existence of tubulocystic chromophobe renal carcinoma

Chromophobe renal cell carcinoma (ChRCC) is a variant of RCC with certain histological, immunohistological and cytogenetic characteristics. It is believed to arise from the intercalated cells of distal tubules and has a more favourable prognosis than other more common subtypes, clear cell and papillary RCC. Microscopically, neoplastic cells of ChRCC are typically arranged in solid sheets, trabeculae, sometimes acini. Areas of tubulocystic morphology have been reported rarely (1). But a prominent multicystic presentation is very unusual.
