Completing a Renal Cell Carcinoma (RCC) diagnosis can sometimes be difficult due to the lack of specific tumour markers, validated and ready to use in the daily clinical practice (1, 2). Liquid biopsies are gaining consensus among the scientific urological community representing a potential adjunctive tool to diagnose kidney malignancies within the next future (3, 4). We report a challenging diagnosis of an isolated retroperitoneal mass, resulting at final histo-pathological examination an unusual RCC degenerating from the tubular cells within the cystic wall, exophytic and contralateral to the renal parenchyma.
SUMMARY
KEY WORDS: Renal Cell Carcinoma, retroperitoneal mass.
RADIOLOGICAL PICTURE QUIZ A UROLOGY CONSULT WAS DONE FOR A 65 YEARS-OLD FEMALE PATIENT DUE TO THE INCIDENTAL FINDING OF A 40 MM RIGHT RETROPERITONEAL MASS WHILE PERFORMING AN ABDOMINAL ULTRASONOGRAPHY (US) (FIGURE 1); DURING REGULAR ONCOLOGICAL FOLLOW UP, AFTER THE EXCISION OF A THORACIC DORSUM MELANOMA IN 2019. A SUBSEQUENT ABDOMINAL COMPUTED TOMOGRAPHY (CT) SCAN OF THE ABDOMEN REVEALED A SOLID 33X37 MM RETROPERITONEAL MASS DISLOCATING THE INFERIOR VENA CAVA (IVC), AND ADHERING TO A SIMPLE CYSTIC FORMATION OF 44X46 MM ADJACENT TO THE ANTERIOR RIGHT RENAL POLE (FIGURE 2). THE RADIOLOGICAL DIAGNOSTIC STUDY OF THE LESION WAS COMPLETED WITH AN ABDOMINAL MAGNETIC RESONANCE IMAGING (MRI) (FIGURE 3). Figure 1.
