Herein, we reported on a case of so lid type of pulmonary actinomycosis
in a 10-year -o ld boy. He had productive cough
for 40 days. Bronchoscopy was normal. Cmputed tomography
revealed a so lid large mass in the upper lobe of his left lung
with mimick ing mal ignant leis ions. He was referred for surgery
and underwent left upper lobectomy. Macroscopically,
the specimen measured 13x9 x5 ern and was creamy to whitish
on cut section. Microscopic find ings included a large number
of inflamma tory ce lls and colonies of actinomyces. Pulmonary
actinomycosis should be included in the differential diagnoses
of pulmonary mass lesions, especially in the young adult s.
