Primary renal lymphoma (PRL) is a rare entity with a history of controversy regarding its existence. Lymphomatous involvement of the kidney is more commonly seen secondarily to spread from an adjacent lymphomatous mass, rather than arising primarily from the kidney. PRL can mimic other renal lesions such as renal cell carcinoma, renal abscess, and metastasis; therefore, an early diagnosis is cr...
BACKGROUND/AIMS We investigated the incidence and clinical characteristics of renal cell carcinoma (RCC) in the native kidney of renal transplant recipients. METHODS Between 1991 and 2010, 1,425 patients underwent kidney transplantation at our institution. We retrospectively evaluated the clinical features and outcomes in renal transplant patients with RCC in the native kidney after renal tra...
Thyroid metastases account for approximately 1.4-3% of all malignancies of the thyroid gland. Thyroid metastases are most common in: clarocellular carcinoma of the kidney, lung cancer, breast cancer, malignant melanoma and cancers of gastrointestinal tract. A rare situation is when thyroid metastasis is diagnosed before detecting primary malignant focus and when it is the first manifestation of...
Erythropoietin was measured by exhypoxic polycythemic mouse method in the course of a 64-yr-old male with renal cell carcinoma associated with erythrocytosis. Serum erythropoietin fluctuated with progression of the disease. Preoperative elevated erythropoietin (0.1 1 U/mI. p < 0.05) subsided after nephrectomy and again increased with developing lung metastasis (0.1 U/mI, p < 0.02). Erythropolet...
E-cadherin, a member of the cadherin family, plays a major role in cell-cell adhesion of normal epithelium. Recent studies have demonstrated that heterogeneous expression, reduction or loss of E-cadherin is involved in invasion and metastasis of cancer cells. In this study, the localization of E-cadherin in the normal human kidney and the relationship between E-cadherin expression and histopath...
Adult pancreatic hemangioma is a rare disease. We presented a case of a woman with pancreatic tail mass mimicking a distant metastasis from the kidney. A 68-year-old woman was found with a left kidney mass on medical checkup. Computed tomography scan showed a 4.3 cm-sized mass in the left kidney, suggesting renal cell carcinoma (RCC), and a strongly enhancing tiny nodule in the pancreatic tail....
Solitary fibrous tumors of the kidney are extremely rare tumors with unpredictable behavior. We describe a case of a patient with a solitary fibrous tumor of kidney with malignant findings with distant metastasis and nephrectomy managed with subcutaneous interferon achieving 23 months of progression-free survival. To date there is no prospective evaluation of any specific modality of treatment,...
Primitive neuroectodermal tumor (PNET) is usually an aggressive, rapidly progressing and metastasizing tumor. Occurrence of this type of tumor in the kidney is considered as unusual and few cases have been reported so far. We present a metastatic PNET arising probably from the kidney in a 17-year-old female patient with local invasion and metastasis to the stomach. PNET should be considered as ...
In the present study, the case of a 51-year-old female with a metastatic tumor in the left kidney originating from cervical carcinoma, is reported. The patient had undergone chemoradiotherapy for stage IIB squamous-cell carcinoma of the uterine cervix 3 years earlier. Computed tomography (CT) identified low-density left renal nodules, which were diagnosed post-operatively as renal cysts during ...
Description of a male patient case, 22 years old, presenting visual acuity decrease in the left eye associated with the diagnosis of metastatic testicular tumor to lung and kidney. Evaluation of the evolution of a choroid lesion compatible with ocular metastasis of testis tumor through ophthalmologic and echographic examinations. There was resolution of the intraocular lesion together with lung...
