Renal cell carcinoma (RCC) is an uncommon malignant tumor of the kidney, particularly in the Asian population. It is more commonly seen in an elderly male patient with typical complains of haematuria, flank pain and lump. Recently incidental diagnosis of small RCCs has been rising due to increased used of abdominal imaging for other reasons. Spontaneous rupture of a renal mass leading to large perinephric collection and presenting as an acute pain abdomen in an adult male is a rare finding but should be considered as a differential diagnosis. The most common cause of spontaneously ruptured renal mass includes benign tumor as angiomyolipoma followed by malignant tumor like RCC, vascular causes, coagulation defects and infection in other cases. Contrast enhanced CT scan is the most common imaging modality used for diagnosis. Initial resuscitation depending up on the patient’s general condition followed by nephrectomy for malignant tumors and embolization for benign tumors is the treatment of choice.

357 Background: Use of cross-sectional imaging has increased the detection rate for small renal tumors; more patients now present with early-stage renal cell carcinoma (RCC) or benign or indolent renal masses. Histopathology after surgical resection is the definitive method for characterizing renal tumors. Stage migration of renal masses creates uncertainty about the percentage of resected masses that will be benign vs malignant. We sought to better define these proportions through a targeted review of the literature. Methods: PubMed/select congresses were searched to identify the histologic classification of renal masses in a representative sample from the contemporary literature: [search] incidence AND (renal cell carcinoma AND benign); incidence AND (renal tumor AND benign); percentage AND (renal cell carcinoma AND benign); limit: 2003–2011. Results: Most representative studies included procedures conducted in the mid-1990s to the mid-to-late 2000s. Studies origin was US (n=8), Korea (n=3), China, Japan, Germany, Austria, Australia, and multisite (Israel/France/US; all n=1). Only 8 studies had n≥500 (range, 70–10,404). The proportion of benign masses are shown (see Table); half of the studies reported values between 16% and 17%. The majority found that benign tumors were more likely to be smaller in size (<4 or <7 cm) than malignant tumors. 11 studies reported the RCC subtype (% clear cell range, 46%–83%). Conclusions: Benign renal tumors occur ~15% of the time and are more prevalent among small masses. Nearly 25% of resected lesions are benign or indolent and may not require surgery. Preoperative discrimination of more aggressive renal masses would be an important clinical advance that could improve clinicians’ diagnostic confidence and guide patient management.

Background: Kidney can be involved in various pathological process. Both benign & malignant tumors can occur in the kidney. They arise from different components of renal parenchyma, notably tubular epithelium.1 99 percent of renal neoplasms are malignant, with renal cell carcinoma and wilm’s tumor being the most common2. Men have higher incidence than women (approximately 1.6:1) and vast majority are diagnosed after 65 years of age. Material and methods: Prospective and retrospective study from January 2017 to December 2019 in the Department of Pathology. Results: The study comprised of 67 cases of neoplastic conditions, out of which 63 cases are malignant and only 4 cases were recorded as benign. Conclusion: Malignant tumors far more common than benign lesions. In adults and older individuals, renal cell carcinoma was most common while among paediatric age group, wilms tumor was most common. Benign tumors were uncommon. Keywords: Kidney, renal cell carcinoma, wilms tumor

Intramammary metastasis of renal cell carcinoma (RCC) is extremely rare, accounting for only 1.5% of all intramammary metastases. Distinguishing intramammary metastases from benign tumors and breast cancer is clinically problematic. Some patients undergo excessive surgery after a misdiagnosis of breast cancer instead of a mammary tumor. We performed a core needle biopsy (CNB) of a breast mass that developed in a 71-year-old woman after surgeries for bilateral RCC and breast cancer, leading to a diagnosis of intramammary metastasis of RCC. In this case, the CNB and immunohistochemical examination were critical for reaching a definitive diagnosis. We conclude that, when examining patients with mammary tumors, establishing their history of malignant tumors may help diagnose intramammary metastasis and select the best treatment strategy.

Renal Mass Biopsy

Pathologic characteristics of extirpated renal cell carcinoma (RCC) specimens <7  cm were reviewed to get better information on technical nuances of renal mass biopsy (RMB). Specimens were stratified according to tumor stage, nuclear grade, size, histology, presence of lymphovas-cular invasion (LVI), necrosis, and sarcomatoid features. When considering pT1 (0–7 cm) tumors pT1b (4–7 cm), RCC masses were more likely to have necrosis (43% vs 16%, P < 0.001), LVI (6% vs 2%, P = 0.024), high-grade nuclear elements (29% vs 17%, P < 0.001), and sarcomatoid features (2% vs 0%, P = 0.006) compared with pT1a (0–4 cm) tumors. Additionally, pT3a tumors were more highly associated with necrosis (P = 0.005), LVI, sarcomatoid features, and high-grade disease (P for all < 0.001) when compared to pT1 masses. For masses <4 cm, pT3a cancers were more likely to demonstrate necrosis (38% vs 16%, P < 0.001), LVI (10% vs 2%, P = 0.037), high-grade nuclear elements (31% vs 17%, P = 0.05), and sarcomatoid features (3% vs 0%, P = 0.065) compared to pT1a tumors. Similarly, for masses 4–7 cm, pathologic T3a tumors were significantly more likely to have sarcomatoid features (16% vs 2%, P < 0.001) and LVI (28% vs 6%, P < 0.001) compared to pT1b tumors. In summary, pT3a tumors and those RCC masses >4 cm exhibit considerable histologic heterogeneity and may harbor elements that are not easily appreciated with limited renal sampling. Therefore, if RMB is considered for renal masses greater than 4 cm or those that abut sinus fat, a multi-quadrant biopsy approach is necessary to ensure adequate sampling and characterization of the mass.
