Renal Pelvic Cancer Revealed by Renal Biopsy

Renal capsule metastasis from renal pelvic cancer: a case report

BACKGROUND Metastatic renal cancers are relatively common. Most are metastases to the renal parenchyma via a hematogenous route and are derived from lung, breast, and gastrointestinal cancer, malignant melanoma, and hematologic malignant cancer. However, little is known about renal capsule metastasis from other cancers. CASE PRESENTATION We report a 71-year-old woman with breast cancer who wa...

Renal Involvement in Non-Hodgkin Lymphoma: Proven by Renal Biopsy

AIMS To determine the spectrum of renal lesions in patients with kidney involvement in non-Hodgkin's lymphoma (NHL) by renal biopsy. METHODS The clinical features and histological findings at the time of the renal biopsy were assessed for each patient. RESULTS We identified 20 patients with NHL and renal involvement, and the diagnosis of NHL was established following the kidney biopsy in 18...

Asymptomatic renal pseudoaneurysm after percutaneous renal biopsy.

A 37-year-old man was referred to Division of Nephrology for a new renal cystic lesion that was found on ultrasonography. Four years prior to presentation, a percutaneous renal biopsy had been performed. Computed tomography scan showed a 4.4-cm-sized renal artery pseudoaneurysm in the left kidney. Selective renal angiography revealed a pseudoaneurysm in the left lower pole of the kidney. The re...

Autophagy by podocytes in renal biopsy specimens.

Autophagy, a process of bulk protein degradation and organelle turnover, is induced under starvation conditions in yeast and plays an important role in developmental processes and human diseases. Autophagy is a nonapoptotic form of programmed cell death. Disturbances in autophagy and programmed cell death may lead to cancer and several degenerative diseases in humans. During the routine ultrast...
