A Case of Hodgkin's Lymphoma Diagnosed by Endobronchial Ultrasound-Guided Transbronchial Forceps Biopsies

Endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA) has proven to be highly accurate in lung cancer diagnosis and staging. However, its efficacy in diagnosing lymphoma, especially Hodgkin’s lymphoma, remains controversial, mainly due to the need for larger biopsies for definitive diagnosis. This case study presents a 53-year-old HIV-positive man with a controlled viral load, who presented with a large left hilar mass and a left upper lobe nodule, both showing significant uptake on positron emission tomography scans. The patient underwent bronchoscopy with bronchoalveolar lavage, EBUS-TBNA using an Olympus™ Vizishot 2 needle (Center Valley, PA), and EBUS-guided transbronchial forceps biopsies (TBFB) of a left hilar lymph node using a 1.8 mm Boston Scientific™ forceps (Marlborough, MA). The EBUS-TBNA revealed granulomas, while the subsequent EBUS-guided TBFB revealed nodular lymphocyte-predominant Hodgkin's lymphoma. EBUS-TBFB may be a promising technique for obtaining larger tissue samples and enhancing diagnostic yield in cases of mediastinal lymphadenopathy with suspected lymphoma.
