Intradural Extramedullary

Background: The cauda equina (CE) is the most common site for intradural extramedullary metastasis from systemic malignancies such as lung, breast, and thyroid carcinomas. However, renal cell carcinomas (RCC), with their high metastatic potential, are rarely responsible for CE metastatic lesions. Here, we report an intradural cauda equina mass, as the first and only site of metastasis of a renal cell carcinoma. Case Description: A 55-year-old female had undergone a left nephrectomy for renal cell carcinoma 8 years ago. She now presented with a unifocal renal cell metastasis to the CE. As such metastases are rare, establishing the correct pathological diagnosis proved to be a challenge. Conclusion: The cauda equina was the first and only site of an 8-year-delayed metastasis attributed to a renal cell carcinoma.

This article presents a clinical case demonsratinga high metastatic potential of clear cell renal cell carcinoma combined with atypical metastases to breast and paranasal sinuses. The prevalence of metastatic lesions to the breast and paranasal sinuses in various malignant tumors depending on their morphological forms is analyzed. The authors present an analysis of data published for the last 30 years. The optimal diagnostic algorithms to detect the progression of renal cell carcinoma and to evaluate the effectiveness of the treatment are considered.

Renal cell carcinomas (RCCs) are known for their unpredictable metastatic pattern. We present the case of a 63-year-old woman who initially presented in 1992 with a metastasis in the left calcaneus that led to the discovery of RCC. In 1998, a new metastasis was found in the ovary. In 2008, the diagnosis of a gallbladder metastasis was made. All metastases were surgically removed; no additional systemic therapies were used. Aggressive surgical treatment can prolong the survival of patients with resectable metastases. Patterns of metastasis are discussed, and a brief review of the literature is given regarding each localization.

Intradural spinal metastasis is rare. This is the third case ever reported on the finding of intradural spinal metastasis from a renal cell carcinoma that had been removed surgically. The patient had a history of epidural metastasis for which excision and anterior stabilization were done 3 years before the new presentation with cauda equina lesion. Seeding from the involved osseous structure to the cerebrospinal fluid through the dura was believed to be the course that tumour had taken to reach the intradural space.

Renal Mass Biopsy

OVERVIEW: The incidental renal mass represents a heterogeneous group that contains both benign and malignant pathologies. The majority of renal cell carcinomas are discovered incidentally, without the presence of symptoms directly related to the mass, and are closely associated with the term small renal masses because of the discovery before the onset of symptoms. In general, small renal masses are defined as 4 cm or smaller, and may account for greater than half of renal cell carcinoma diagnosis. The use of renal mass biopsy may offer additional pathological information but the clinician must be reminded of the technical and diagnostic limitations of renal mass biopsy. Patient-dependent factors, such as life expectancy and comorbidities, guide the management of small renal masses, which include active surveillance, partial nephrectomy, radical nephrectomy, and ablative techniques (cryoablation and radiofrequency ablation). Partial nephrectomy has demonstrated durable oncologic control for small renal masses while preserving renal function and, if feasible, is the current treatment of choice. In the other extreme of the renal cell carcinomas spectrum and in the presence of metastatic disease, the removal of the renal primary tumor is termed cytoreductive nephrectomy. Two randomized trials (SWOG 8949 and EORTC 30947) have demonstrated a survival benefit with cytoreductive nephrectomy before the initiation of immunotherapy. These two studies have also been the motivation to perform cytoreductive nephrectomy in the targeted therapy era. Currently, there are two ongoing randomized prospective trials accruing to investigate the timing and relevance of cytoreductive nephrectomy in the contemporary setting of targeted therapy.

The incidence of renal cell carcinomas in adults ranges has been increasing over the past decades in both men and women. Once the incidence was 2.9%, now is reported to have increased to 3%–5% with male predominance according to the most recent reports of cancer statistics. The disease typically describes a group of different histopathological subtypes; the most common is clear cell carcinoma which accounts for 70%–80% of the diagnosed cases, while papillary renal cell carcinoma and chromophobe types represent 20% and 5%, respectively. In 1996, the renal cell carcinomas Heidelberg classification was introduced by Delahunt et al. It divides renal cell tumors into benign and malignant parenchymal neoplasms, excluding Wilm’s tumor and secondary metastases and limiting each subcategory to the most commonly documented genetic abnormalities, if applicable. In this report, we discuss a case of metastatic type I papillary renal cell carcinoma treated with the anti-vascular endothelial growth factor receptor sunitinib and showing marked long-term clinical response. Through this case, we highlight the importance of re-classifying papillary renal cell carcinoma subtypes to prioritize the clinical management of these cases.

Renal cell carcinomas in children are extremely rare and are usually associated with specific chromosomal rearrangements, different from those seen in adult patients. We present the case of a 9-year-old girl with a renal cell carcinoma with t(X;17) diagnosed at our institution. We also review the pertinent literature, with an emphasis on the genetic and molecular aspects associated with this rare neoplasm.
