Sample Signout
If no additional specific histologic features are identified, consider the following approach to signing the case out:
Fibrosing Interstitial pneumonia (see comment).
Comment: The biopsy shows advanced fibrosis with architectural distortion. No additional specific histologic features to indicate an etiology are identified. There is a broad differential diagnosis including UIP, chronic HP, CTD-associated ILD, and pneumoconiosis among others. The diagnosis of ILD requires a multidisciplinary approach. Correlation with imaging studies and clinical history is suggested.
