4583 Eus fna combined with flow cytometry and immunocytochemistry in the diagnosis of lymphoma.

Endoscopic Ultrasonography

“…EUS-FNA in colorectal cancer has been previously discussed [107,108]. EUS-guided FNA with flow cytometry and immunocytochemistry is useful in the diagnosis of lymphoma [109]. Injection of CO 2 microbubbles may improve the differentiation between malignant and benign lymph nodes on EUS [110].…”

EUS-guided fine-needle aspiration in the mediastinum

“…25,26 However, some reports have described its use in the mediastinum as well. 27 It is imperative that in cases where mediastinal lymph nodes are suspicious and when the diagnosis of lymphoma is being considered, the endosonographer must obtain ample EUS-FNA specimens and submit a separate container for flow cytometry and immunocytochemistry. This will improve the yield of EUS-FNA and may influence diagnostic workup and treatment decisions.…”

“…This will improve the yield of EUS-FNA and may influence diagnostic workup and treatment decisions. 27 We recently evaluated a patient with a history of pheochromocytoma. The patient had a chest CT that showed a mediastinal mass located at the azygoesophageal recess.…”
