This case highlights a rare adenocarcinoma of the lung with desquamative interstitial pneumonia (DIP)-like features. Pathologists should consider immunohistochemical markers for lung cancer with this unexpected histological pattern.
Area of Science:
- Pulmonology
- Oncology
- Pathology
Background:
- Part-solid lung nodules can be challenging diagnostic entities.
- Unexpected histological findings in lung nodules may lead to diagnostic confusion.
- Desquamative interstitial pneumonia (DIP) is a diffuse interstitial lung disease, while respiratory bronchiolitis (RB) is its focal counterpart.
