Non-pneumophila species pneumonia with orange-coloured sputum.

We herein report an immunocompromised patient familiar with gardening admitted to our hospital suffering from severe pneumonia caused by . We suspected non-pneumophila species pneumonia because of gardening habits, the negative urine antigen test and the non-significant Gram staining results of orange-coloured sputum. The pathogen was identified using mass spectrometry analysis of bronchoalveolar lavage fluid.

Anti-neutrophil cytoplasmic antibody-associated vasculitis complicated with diffuse alveolar haemorrhage and central nervous system vasculitis.

Diffuse alveolar haemorrhage and central nervous system vasculitis are life-threatening complications of anti-neutrophil cytoplasmic antibody-associated vasculitis. The simultaneous occurrence of diffuse alveolar haemorrhage and central nervous system vasculitis is a rare presentation of antibody-associated vasculitis. Its diagnosis by histopathology is difficult because biopsy is difficult to perform, and urgent treatment is needed.
