Metastatic renal cell carcinoma from a native kidney of a renal transplant patient diagnosed by endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) biopsy

چکیده
Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) biopsy sampling of enlarged lymph nodes is increasingly used to diagnose metastatic tumors, especially of the gastrointestinal tract and the lungs. Herein, we describe the diagnosis of metastatic renal cell carcinoma from a native kidney of a 54 year-old male patient, who had a 5-years history of renal transplant, by EUS-FNA of mediastinal and celiac lymph nodes. Histological and immunohistochemical findings confirmed the origin of metastatic tumor. EUS-FNA with proper cytological evaluation can be useful in the diagnosis of metastatic renal cell carcinoma in renal transplant patients.

Metastatic Renal Cell Cancer to Thyroid Diagnosed by Endoscopic Ultrasound Guided Fine Needle Aspiration Technique
Medical literature about the role of endoscopic ultrasound (EUS) in identifying thyroid lesions is limited. We present a case of secondary thyroid cancer from renal cell carcinoma (RCC) metastasis, diagnosed by thyroid EUS-fine needle aspiration (FNA) approach that was done for staging of esophageal adenocarcinoma, in a patient with 11-year history of complete right nephrectomy for RCC. An 81-y...

INTRODUCTION The increasing use of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) cytology to examine pancreatic neoplasms has led to an increase in the diagnosis of metastases to the pancreas. Renal cell carcinoma (RCC) is the most common metastasis to the pancreas. Our study examines 33 cases of metastatic RCC to the pancreas sampled by EUS-FNA from four large tertiary care hos...

We fully support the use of a single linear endobronchial ultrasound (EBUS) bronchoscope for both endobronchial ultrasoundguided transbronchial needle aspiration (EBUS-TBNA) and endoscopic ultrasound-guided fi ne-needle aspiration (EUS-FNA) of mediastinal lymph nodes, as reported in the recent CHEST article by Herth et al. 1 Having initially established and reported our own results with EBUS-TB...
متن کاملPancreatic metastases from ovarian carcinoma--diagnosis by endoscopic ultrasound-guided fine needle aspiration.
Pancreatic metastases are very uncommon and originate most commonly from lung, colon, breast and kidney cancer. Ovarian adenocarcinoma has been reported as a primary site of pancreatic metastasis, but its diagnosis has rarely being reported by endoscopic ultrasound guided fine needle aspiration (EUS-FNA). We report a case of multiple metastases to the pancreas from ovarian carcinoma occurring f...
