Metastatic renal cell carcinoma is renowned for its potency to spread to almost any organ of the body; however metastasis to the gall bladder is very rare. We present a case of a 48 year old man who initially demonstrated renal cell carcinoma, and in who gallbladder metastasis was later detected. A review of the literature revealed only a small number of cases of renal cell carcinoma metastasizing to the gallbladder, and these were primary found upon necropsy. Gall-bladder metastasis in this case was detected clinically.

Since 2006, tyrosine kinase inhibitors and anti-angiogenic drugs have revolutionized the treatment of metastatic renal cell carcinoma by improving progression-free survival and overall survival. The prognostic factors in metastatic renal cell carcinoma treated by targeted therapy include anatomical, histological, clinical, biological, and molecular parameters. The accuracy of these prognostic factors are not high when applied alone. A renal cancer prognostic system that combines all these prognostic factors can improve the risk assessment of renal cancer and prognosis prediction, and thus guide clinical decision-making.

We report a case of pathologically proven simultaneous duodenal and colonic metastases about four years after nephrectomy for mixed clear and granular cell type renal cell carcinoma (RCC). A 76-year-old female patient who had undergone a left radical nephrectomy 4 years previously for RCC presented with a 1-month history of dyspepsia and pain in the right upper abdomen. An abdominopelvic CT scan showed circumferential wall thickening with high enhancement at the second portion of the duodenum and additional enhancement of an irregular protruding mass into the lumen of the ascending colon. A gastroscopy showed a large and ulcerative protruding mass nearly obstructing the second portion of the duodenum. A colonoscopy revealed a polypoid, nodular and purplish mass in the ascending colon. Microscopy of the biopsy specimen showed the features identical to those of the RCC which was resected 4 years earlier in this patient. We believe this to be the first case illustrating a metastatic renal cell carcinoma as simultaneous duodenal and colon masses.

Objective: To report a rare case of epididymal liposarcoma with multiple metastases to the retroperitoneal space and peritoneal cavity for the purpose of improving the diagnosis and treatment of the disease. METHODS: We retrospectively analyzed the clinical data about a case of epididymal liposarcoma with multiple metastases to the retroperitoneal space and peritoneal cavity, reviewed relevant literature at home and abroad, and investigated the presentation, diagnosis and treatment of the disease. RESULTS: A 47-year-old male patient with epididymal liposarcoma underwent radical left orchiectomy with high ligation of the spermmatic cord. Ten years later, recurrence and metastasis were observed in the retroperitoneal space with a mass of 15.6 × 9.4 × 25.5 cm occupying an area from the upper pole of the left kidney to the pelvic cavity and enclosing the left kidney and upper ureter, for which the patient received radical resection of the retroperitoneal tumor. However, multiple retroperitoneal and intraperitoneal metastases occurred again 4 years later, which was treated by another surgical resection. The patient died of lung failure a year later. CONCLUSIONS Epididymal liposarcoma is a rare entity, which can be diagnosed by careful clinical and radiological examinations and confirmed by pathology. For its treatment, radical inguinal orchiectomy should be performed as early as possible, but the roles of adjuvant radiotherapy and chemotherapy remain controversial. Given the high rate of recurrence and metastasis, long-term follow-up is necessitated for the patient postoperatively.

Paraganglioma is a rare neuroendocrine tumor arising from the undifferentiated cells of the primitive neural crest. We report a case of malignant paraganglioma originating from the left kidney. The 55-year-old female patient was admitted for intractable cough for a month and the presence of a solid mass in the left lung detected by computer tomography (CT). Sonography revealed a mass in the left kidney after admission. Complete surgical resection of the tumor was performed and the diagnosis of malignant paraganglioma originating from the left kidney was established pathologically. During the follow-up for 12 months, the patient showed a good general condition and sonography revealed no evidence of recurrence. Based on these findings, we discussed the diagnosis of this disease using medical imaging modalities.
