Primary Pulmonary Hodgkin's Lymphoma: A Rare Etiology of a Cavitary Lung Mass.

Primary pulmonary Hodgkin's lymphoma (PPHL) is an uncommon disease. This entity is different from Hodgkin's lymphoma with parenchymal or nodal lung involvement. In this report, we highlight the case of a young female presenting with a six-month history of a productive cough and constitutional B symptoms. Imaging showed cavitary lesions in the right-upper and right-middle lobes. The initial comprehensive infectious workup was negative. Histopathology and immunochemistry confirmed the diagnosis of PPHL. PPHL is an uncommon etiology of cavitary lung lesions. Despite its diagnostic difficulties, awareness of such a disease is crucial, given its high rate of response to treatment, especially in the young population.
