SILVA, Renata Violante; APOLINARIO, Dulce; LOUREIRO, Ana Isabel    GUIMARAES, Fernando. Actinomycosis with Organizing Pneumonia, Cervical Pyomyositis and Brachial Diparesis. []. , 23, 4, pp.39-41. ISSN 0872-671X.

Actinomycosis is an uncommon infectious disease nowadays, usually presenting a relenting course, with suppuration, sometimes complicated by sinus tract formation. Actinomyces are agents of normal flora existing on many human mucosae, usually nonpathogenic. However, under certain situations of mucosal disruption they can produce disease. Oral-cervicofacial disease is the most common form of acinomycosis, followed by abdominopelvic and pulmonary forms. The diagnosis is often difficult and it is based on microbiological isolation of actinomyces or recognition of the typical ‘sulfur granules’ in affected tissues or purulent material. In this case-report we present the rare situation of a 49-year-old man with cervical form of the disease, complicated by prevertebral myositis and involvement of nervous roots, resulting in brachial diparesis, as well as by organizing pneumonia.
