Acute fibrinous and organizing pneumonia associated with Candida: A case report.

Background: Acute fibrinous and organizing pneumonia (AFOP) is a rare form of pneumonia, is characterized by the deposition of fibrin in alveoli, the formation of fibrin spheres, and deposition of fibrin in alveolar junctions and bronchioles adjacent to or adjacent to the alveoli, forming institutional loose connective tissue.The clinical characteristics of AFOP lack specificity. We report a special case of AFOP that may be associated with Result: In this patient who was early misdiagnosed with community-acquired pneumonia (CAP), the empirical anti-infective treatment was ineffective, and various infectious and non-infectious factors were excluded. Flexible bronchoscopy was subsequently performed, and metagenomics Next Generation Sequencing (mNGS) of Bronchoalveolar lavage fluid (BALF) showed Conclusion: The clinical manifestation, laboratory examination and imaging examination of AFOP has no specificity, lung biopsy and pathological examination should be carried out to make a clear diagnosis by comprehensively considering the clinical manifestations, auxiliary examination, pathology and other aspects of the patients. After definite diagnosis, it is still necessary to rule out various diseases and environmental exposure and further classify them as idiopathic or secondary, so as to choose monotherapy or combination therapy.
