Pulmonary actinomycosis in children: A prompt diagnosis can prevent surgery

Pulmonary actinomycosis is an extremely rare disease in children. The diagnosis is challenging as the clinical presentation and radiological investigations may be atypical. We report a case of a pulmonary lesion extending to the chest wall posing as a malignant lesion. Biopsy revealed colonies of Actinomyces. Antibiotic therapy resolved the mass. A rare diagnosis of pulmonary actinomycosis should be kept as a differential diagnosis of such a mass in children.
