Rounded atelectasis, abbreviated RA, is a benign pathology of the lung that may be mistaken for lung cancer.[1][2]

General

  • Benign clinical diagnosis.
  • May be biopsied to exclude malignancy.
  • Type of lung collapse[3] often associated with asbestos exposure.

Clinical (radiologic findings):[3]

  • Pleural thickening.
  • Mass lesion with "comet tail" (curvilinear opacification of bronchi and vessels).

Microscopic

Features:

  • Pleural fibrosis.
  • No features of malignancy.

Note:

  • Findings on core biopsy are non-specific.

DDx:

  • Pleural plaque.

Sign out

Lung Lesion, Right Lower Lobe, Core Biopsy:
- Benign fibrous tissue and skeletal muscle.
- NEGATIVE for lung parenchyma. 
- NEGATIVE for evidence of malignancy.

Comment:
Clinical correlation is suggested.
