A 64-year-old man presented a nodular shadow in the right lower lobe on a chest computed tomography (CT) scan. The nodule had grown remarkably in 3 years and was suspected to be a lung cancer. An open lung biopsy showed a solid lesion adjacent to lung abscess, and histopathological examination of a biopsy specimen revealed follicular bronchiolitis. Follicular bronchiolitis is a rare condition and is reported to occur mainly in association with connective tissue disorders or immunodeficiency syndromes. In such conditions, it generally exhibits bilateral, diffuse, small nodular lesions or ground-glass opacities. The present case was not associated with such underlying diseases and was thought to have occurred in association with lung abscess. Few cases of follicular bronchiolitis caused by non-specific airway infection have been reported in Japan.
