RESUMO: A actinomicose é uma infecção bacteriana, supurativa e crónica caracterizada por multiplos abcessos, trajectos fistulosos, fibrose e tecido de granulação envolvendo a face, pescço, tórax ou abdomen devido a uma bactéria anaeróbica,gram positiva, saprófita e que só vive em cavidades. A actinomicose primária pulmonar é uma doença rara e provà velmente resulta da aspiração de secrções da orofaringe. Sem sinais clÃnicos caracteristicos, pode apresentarse como uma doença respiratória crónica. Aproximadamente 90% dos doentes são submetidos a procedimentos de diagnóstico e tera-pêutica baseado numa hipótese errada. Os autores apresentam uma revisão da actinomicose torácica a propósito de três casos clÃnicos. Um caso era suspeito de ter um tumor pulmonar,o segundo caso foi considerado ser a recurrência de uma doença maligna e o terceiro caso apresentouse com uma forma de pneumonia recidivante após aspiração de um corpo estranbo. O diagnóstico foi confirmado através do exame histológico.REV PORT PNEUMOL 1999; V (3): 341-348 ABSTRACT: Actinomycosis is a chronic, suppurative bacterial infection characterized by multiple abscesses, sinus tracts, fibrosis, and granulation involving the face, neck, thorax and abdomen due to an anaerobic gram positive commensal bacteria, harbored in the healthy cavities. Primary actinomycosis of the lung is a rare disease and probably results from aspiration of oropharyngeal secretions. Without characteristic clinical signs, may present as chronic respiratory, disease with abnormality of radiography. Approximately 90% of patients have undergone diagnostic and therapeutics procedures based on a wrong diagnostic hypothesis. The authors present a comprehensive review of thoracic actinomycosis apropos of three clinical cases. One case was suspected as lung tumor, the second case was consider as recurrence of lung malignancy, and the third case present as recurrent pneumonia after foreign body aspiration in airway. Final diagnosis was confirmed by histology examination.REV PORT PNEUMOL 1999; V (3): 341-348 Palavras-chave: Actinomicose, Radiografia de tórax, Broncoscopia, Grânulos sulfurosos, Penicilina G, Key-words: Actinomycosis, Thoracic radiography, Bronchoscopy sulfur granules, Penicillin G
