Thoracic actinomycosis imitating a malignant chest wall tumor. Diagnosis: pulmonary actinomycosis

Actinomicose torácica simulando doença neoplásica em Pediatria

OBJETIVO: Descrever um caso de actinomicose pulmonar em paciente pediátrico. DESCRIÇÃO DO CASO: Menina de dez anos, saudável, com história de dor torácica há três meses, evoluindo há dois meses com abaulamento em parede torácica anterior esquerda. Ao exame físico, apresentava massa de 8,0cm de diâmetro em região inframamilar esquerda, sem sinais flogísticos. A tomografia do tórax mostrou processo expansivo em parede torácica anterior esquerda. Realizou-se biópsia e a cultura do material identificou Actinomyces israelli. Foi tratada com penicilina cristalina e amoxicilina, com desaparecimento da massa torácica. COMENTÁRIOS: A actinomicose é uma doença bacteriana rara, indolente, invasiva e, frequentemente, não considerada em crianças como causa provável de massas torácicas, sendo incomum o diagnóstico precoce.

Pulmonary actinomycosis as a pseudotumor: a rare presentation

Some lung diseases are true diagnostic challenges due to their various clinical presentations. Actinomycosis is one such disease, potentially affecting various organs and systems. We report the case of a patient with pulmonary actinomycosis as a pseudotumor, which is usually only diagnosed by thoracotomy or thoracoscopy.

A case of pulmonary aspergilloma and actinomycosis

Pulmonary aspergilloma and pulmonary actinomycosis are rare pulmonary infectious diseases. Clinical manifestations of pulmonary aspergilloma and pulmonary actinomycosis include chronic cough, fever, chest pain, haemoptysis and other pathologies, but some patients may be asymptomatic. We report a case of a healthy 33-year-old woman without any underlying diseases, who was admitted to Zhongxing Branch of Taipei City Hospital, Taiwan, for intermittent haemoptysis and right upper chest pain, which had persisted for several months. A chest radiograph revealed a focal consolidation in the right upper lobe (RUL) of the lung, which grew in size over time. A sputum study and bronchoscopy revealed no positive findings, although malignancy could not be ruled out. Thus, the patient received a wedge resection of the RUL lesion. Subsequent, pathological examination demonstrated the presence of pulmonary aspergilloma and pulmonary actinomycosis. The patient's symptoms resolved after resection of the RUL lesion.

Mixed infection involving Actinomyces, Aggregatibacter, and Fusobacterium species presenting as perispinal tumor

A representative case in which a polymicrobial infection involving Fusobacterium nucleatum, Actinomyces israelii and Aggregatibacter (formerly Actinobacillus) actinomycetemcomitans was initially diagnosed as malignancy in an edentulous patient. Additional history obtained after the nature of the syndrome was elucidated revealed that he had had his two remaining teeth extracted four months prior to this episode.
