Clinical Challenges and Management Strategies in Pulmonary Large-Cell Neuroendocrine Carcinoma.

ABSTRACT

Pulmonary large-cell neuroendocrine carcinoma (LCNEC) is a rare but aggressive malignancy of the lung. Its nonspecific presentation and propensity for severe disease at the time of diagnosis create challenges in treatment. We report a case of an asymptomatic 61-year-old female who was incidentally found to have a pulmonary nodule after a fall. Upon further workup, she was found to have an aggressive LCNEC. The patient underwent a robotic-assisted left upper lobectomy, which was complicated by left lower lobe bronchus kinking and post-obstructive atelectasis, warranting further management by thoracic surgery. The patient additionally underwent video-assisted thoracoscopic surgery (VATS), open thoracotomy, pneumopexy, and bronchial stenting. This case highlights the need for strategies for early detection in at-risk populations. A multidisciplinary approach, which may involve both medical and surgical subspecialties, is essential in the management of this complex disease from the time of diagnosis to follow-up postoperatively to achieve the best clinical outcome.
