ABSTRACT
Gastrointestinal metastasis of a renal cell carcinoma is very rare, and the clinical course of the disease ranges from months to several decades. We experienced a case of solitary duodenal metastasis about 22 years after a right nephrectomy for clear-cell type renal cell carcinoma in a 77-year-old man who complained of melena. This case is the longest reported time interval between surgical nephrectomy to presentation with a duodenal metastasis. Patients usually present with recurrence within a year after radical nephrectomy but can present after many years, warranting lifelong surveillance.

Thin basement membrane disease is defined as diffuse thinning of the glomerular basement membrane, and is clinically characterized by persistent hematuria, minimal proteinuria, normal renal function, and a benign course. It can occur together with other glomerular diseases. We experienced a case of thin basement membrane disease concurrent with minimal-change disease. Treatment with corticosteroid resulted in improved proteinuria and peripheral edema during the follow-up period.

Primary prostate sarcomas are rare neoplasms that accounts for less than 0.1% of primary prostate malignancies. Leiomyosarcoma is the most common histologic type in adults, whereas rhabdomyosarcoma is more common in pediatric patients. Historically, long-term survival rates for adult patients with prostate sarcoma are have been poor. So, early diagnosis is very important. Surgery has been the mainstay of treatment. We experienced a case of primary stromal sarcoma of the prostate. We review the literature to discuss the clinical, diagnostic, and therapeutic aspects of this uncommon tumor.

Most cases of cardiac metastasis from renal cell carcinoma (RCC) involve the vena cava or right atrium. Left ventricular metastases from RCC without involving the vena cava or right atrium are extremely rare. Herein we report a case of RCC with left ventricular metastasis causing left ventricular outflow obstruction (LVOT).
