title: [Thoracic actinomycosis: three cases].
abstract: Actinomycosis is a rare condition which, in the thoracic localisation, can mimic cancer or tuberculosis. We report a series of three case of thoracic actinomycosis treated in the Ibn Sina University Thoracic Surgery Unit in Rabat, Morocco. CASE N degrees 1: This 45-year-old patient presented a tumefaction on the left anterior aspect of the chest. Physical examination identified a parietal mass with fistulisation to the skin. Radiography demonstrated a left pulmonary mass. Transparietal puncture led to the pathological diagnosis of actinomycosis. The patient was given medical treatment and improved clinically and radiographically. CASE N degrees 2: This 68-year-old patient presented repeated episodes of hemoptysis. The chest x-ray revealed atelectasia of the middle lobe and bronchial fibroscopy demonstrated the presence of a bud in the middle lobar bronchus. Biopsies were negative. The patient underwent surgery and the histology examination of the operative specimen revealed pulmonary actinomycosis. The patient recovered well clinically and radiographically with antibiotic therapy. CASE N degrees 3: This 56-year-old patient presented cough and hemoptysis. Physical examination revealed a left condensation and destruction of the left lung was noted on the chest x-ray. Left pleuropulmonectomy was performed. Histological analysis of the surgical specimen identified associated Aspergillus and Actinomyces. The outcome was favorable with medical treatment. The purpose of this work was to recall the radiological, clinical, histological, therapeutic, outcome aspects of this condition and to relate the problems of differential diagnosis when can suggest other diseases.
