Disseminated actinomycosis due to Actinomyces meyeri and Actinobacillus actinomycetemcomitans.
A 44-year-old man presented with pulmonary lesions and neurological symptoms suggestive of lung carcinoma with cerebral metastases. He had non-specific chest X-ray findings since 6 years and he also suffered from relapsing purulent skin lesions which resolved spontaneously or by short courses of antibiotic treatment. When corticosteroids were given, multiple subcutaneous swellings developed that spontaneously ruptured. The pus contained Actinomyces meyeri and Actinobacillus actinomycetemcomitans. On operation, the intracerebral lesions appeared to be abscesses and the same bacteria were cultured as from the skin lesions. Bronchoscopical examination did not reveal a diagnosis. Amoxicillin was given for 12 months and the patient recovered.
