“…Patients age ranged from 58 to 79 years (median 71 years), slightly older than the average age for all RCC patients. The RCC histological subtype was clear cell in 1 case [4], papillary cell in 3 cases [2, 3, 6] and granular cell in 1 case [5] (note: it has recently been shown that “granular cell” type RCC is not an independent histological type). The location of liposarcoma was perirenal [4, 5] in 2 cases, retroperitoneal [2, 6] in 2 cases, and cardiac [3] in 1 case (found by autopsy).…”
