[A clinico-pathological study of 14 open lung biopsy cases of clinically suspected diffuse panbronchiolitis]

Abstract:
To elucidate the relationship between clinical and histopathological findings in diffuse panbronchiolitis (DPB), we reviewed 14 open lung biopsy cases clinically suspected of having DPB. According to the histopathological criteria for "PB unit lesion" proposed by Kitaichi in 1988, 11 cases were diagnosed as having DPB; 3 cases were excluded by the criteria. The pathological diagnosis was not concordant with the evaluation according to the clinical diagnostic criteria for DPB previously proposed by Homma et al. in 1983. The present results indicate 1) the necessity to reexamine the pathological criteria for DPB, especially in open lung biopsy cases, and 2) the difficult differential diagnosis between DPB cases and non-DPB ones by current clinical diagnostic criteria.
Insights
Clinical and histopathological findings in diffuse panbronchiolitis (DPB) show discrepancies. Current diagnostic criteria for DPB require reevaluation, particularly for open lung biopsy cases.
Area of Science:
- Pulmonology
- Pathology
- Medical Diagnostics
Context:
- Diffuse panbronchiolitis (DPB) is a chronic airway inflammatory disease.
- Accurate diagnosis relies on correlating clinical and histopathological findings.
- Open lung biopsy is an invasive procedure used for definitive diagnosis.
Purpose:
- To investigate the concordance between clinical and histopathological diagnoses of diffuse panbronchiolitis (DPB).
- To evaluate the adequacy of existing diagnostic criteria for DPB.
Summary:
- This study reviewed 14 open lung biopsy cases suspected of DPB.
- Histopathological analysis using Kitaichi's criteria diagnosed 11 cases as DPB.
- A significant discordance was found between pathological diagnoses and clinical criteria (Homma et al., 1983).
Impact:
- Highlights the need to revise histopathological criteria for DPB, especially in biopsy specimens.
- Underscores the challenges in differentiating DPB from other conditions using current clinical criteria.
- Suggests potential improvements in diagnostic accuracy for DPB.
