ABSTRACT

Nondiphtherial corynebacteria are ubiquitous in nature and commonly colonize the skin and mucous membranes of humans, however they rarely account for clinical infection. We present the first reported case of multiple pulmonary nodules caused by Corynebacterium striatum. The infection occurred in a 72-year-old immunocompetent female, and the diagnosis was obtained by Gram's stain and culture of lung biopsy. C. striatum should be recognized as a potential pathogen in both immunocompromised and normal hosts in the appropriate circumstances.


Bacilos não diftéricos são ubiquitários na natureza e comumente colonizam a pele e as membranas mucosas humanas, contudo eles raramente acarretam doença clínica. Apresentamos o primeiro relato de múltiplos nódulos causados por Corynebacterium striatum. A infecção ocorreu numa mulher imunocompetente de 72 anos de idade e o diagnóstico foi obtido pela coloração de Gram e cultivo de biópsia pulmonar. C. striatum deve ser reconhecido como potencial patógeno tanto em pacientes imunodeprimidos como em hospedeiros normais, em circunstâncias apropriadas.

ABSTRACT

We present a case of histoplasmosis with multiple pulmonary nodules in a patient with a history of melanoma. This case closely simulated malignancy, including the presence of feeding vessel sign, which occurs in pulmonary metastasis. We emphasize the need to be aware of this infection in areas where histoplasmosis is endemic.


Apresentamos caso de histoplasmose com múltiplos nódulos pulmonares em paciente com história de melanoma. Este caso simula malignidade, incluindo o sinal de vaso nutridor que ocorre na metástase pulmonar. Enfatizamos a necessidade de considerar esta infecção em áreas onde a histoplasmose é endêmica.
