A perplexing primary novel hilar lesion: Remember the pneumonic PPNHL!

ABSTRACT

A 60-year-old female presented with dyspnea, cough, and chest pain with a left hilar mass lesion. In our case, clinicoradiological correlation, bronchoscopy, and computed tomography-guided biopsy revealed the diagnosis of primary pulmonary non-Hodgkin's lymphoma (PPNHL) on histopathology and immunohistochemistry. We discuss the approach to hilar masses. PPNHL is a rare malignant lymphoma most common being mucosa-associated lymphoid tissue lymphoma. Various therapeutic options are available. The chemotherapy regimen consisting of CHOP (cyclophosphamide, doxorubicin, vincristine, prednisolone) is preferred.
