Synchronous Diagnosis of Squamous Cell Carcinoma of the Lung and Mixed Cellularity Hodgkin Lymphoma of the Nasopharynx.

ABSTRACT

Hodgkin lymphoma (HL) is a highly curable B cell lymphoproliferative neoplasm with a bimodal age distribution. Lung cancer is the leading cause of cancer-related deaths in both sexes. We present a rare case of synchronous squamous cell carcinoma (SCC) of the lung and mixed cellularity HL of the nasopharynx. A gentleman in his 70s presented with right-sided chest pain and shortness of breath. CT of the chest showed a peripheral lung mass, and a biopsy confirmed SCC of the lung. The patient underwent a positron emission tomography/computed tomography (PET/CT) for staging that revealed an 18F-fluorodeoxyglucose (FDG)-avid mass in the nasopharynx. Flexible nasal endoscopy and biopsy of the nasopharyngeal mass revealed mixed cellularity classical HL. The patient was started on chemoimmunotherapy for lung cancer. Unfortunately, two months after initiation of treatment, the patient died from COVID-19 pneumonia and multiorgan failure.
