title: [Thoracic actinomycosis in the differential diagnosis of neoplasm: a propos of a case].
abstract: Actinomycosis is an infrequent infection caused by bacteria from Actinomyces genus that manifests as a chronic, suppurative and progressive disease. It's more common in men. Thoracic actinomycosis occurs in 15% of the cases, and infection of the chest wall is less frequent. The clinical presentation mimics tuberculosis or neoplastic processes. In this article we present the case of a 63 year-old man with no comorbidity, with pulmonary actinomycosis involving the chest wall mimicking a neoplastic process, basing the diagnosis on histopathologic findings.
