Incidental Finding of Renal Cell Carcinoma in Recurrent Retroperitoneal Liposarcoma

The small renal masses SRMs have increased over the past two decades due to more liberal use of imaging techniques. SRMs have allowed discussions regarding their prognostic, diagnosis, and therapeutic approach.

Clinical presentation, incidental diagnosis, and prognosis factors of SRMs are discussed in this review. SRMs are defined as lesions less than 4 cm in diameter. Clinical symptoms like hematuria are very rare, being diagnosed by chance incidental in most cases.

Size, stage, and grade are still the most consistent prognosis factors in RCC. An enhanced contrast SRM that grows during active surveillance is clearly malignant, and its aggressive potential increases in those greater than 3 cm.

Clear cell carcinoma is the most frequent cellular type of malign SRM. Only some SRMs are benign. The great majority of malign SRMs have good prognosis low stage and grade, no metastasis with open or laparoscopic surgical treatment nephron sparing techniques.

Active surveillance is an accepted attitude in selected cases. Although mean tumor size has decreased in the last years, several studies indicate that this variable is one of the most important prognosis factors for RCC, and it has also contributed to the last modifications of RCC staging and treatment [ 1011 ].

Years ago, when most RCC were symptomatic, hematuria was the main symptom, so asymptomatic tumors were diagnosed later or not diagnosed. These data support the fact that some RCC have a favorable evolution and support active surveillance in select cases.

Natural history of SRM has not been historically well established because most masses were surgically removed soon after diagnosis.

A significant number of SRMs are incidentally diagnosed [ 212 ]. Renal masses benign and malign can be considered incidental if they are diagnosed in the absence of symptoms or signs.

Small renal masses include all solid or complex cystic lesions lower than 4 cm. Among them, different benign tumors are found in a Incidental renal tumors have a mean size of 3. Nevertheless, tumors greater than 4 cm could be incidental.

Incidental diagnosis is performed in the If a cut-off should be made, most cases of RCC lower than 7 cm are incidentally discovered, while tumors greater than 7 cm are mainly symptomatic but, as mentioned previously, this cannot be taken as a rule [ 7 ]. Prognostic of those RCC diagnosed by hematuria is worse than those incidentally diagnosed [ 23 ].

Stage I lesions were observed in Among the different entities causing the incidental diagnosis of an SRM, many have been considered; evaluation for other malignancy No differences were found among incidental or symptomatic RCC according to age, sex, and laterality [ 15 ].

Laboratory findings have a significant impact on the patients with organ-confined RCC prognosis. Some demographic data may help to presume the matter of SRM: RCC is unusual in young patients; angiomyolipomas and multilocular cystic nephromas are more common in women [ 25 ]. However, as the patient ages, the SMR stage is higher; so the incidence of SRM finally staged as pT3 tumors in younger than 45 years, 45—75 years, and older than 75 years is 2.

The probability of developing metastases, with 12 years follow-up, is greater in men [ 27 ].

Apr 16,  · Renal cell carcinoma (RCC) may remain clinically occult for most of its course. The classic triad of flank pain, hematuria, and flank mass is uncommon (10%) and is indicative of advanced disease.

Twenty-five to thirty percent of patients are asymptomatic, and their renal cell carcinomas are found on. The widespread use of cross-sectional imaging techniques means that renal masses are now a common incidental finding. The term renal mass covers a diverse group of pathologic entities, including inflammatory, vascular, and benign tumors and neoplastic lesions.

Mar 21,  · The present iconographic essay developed with multidetector computed tomography images of selected cases from the archives of the authors’ institution, is aimed at describing imaging findings that can help in the diagnosis of renal cysts.
