ABSTRACT

A 68-year-old man diagnosed with lung adenocarcinoma (cT3N3M1c, Stage IVB) received second-line chemotherapy with docetaxel and ramucirumab, which induced Grade 4 neutropenia and Grade 3 oral mucositis. A chest X-ray on day 56 showed a new cavitary lesion in the left upper lung field. Neisseria sicca was detected in the tissue culture obtained by endobronchial ultrasonography with a guide sheath (EBUS-GS). We diagnosed a lung abscess due to N. sicca and treated with amoxicillin. There have been only four previous cases of N. sicca pneumonia reported, and this is the first case report of lung abscess caused by N. sicca.
