Solitary fibrous tumour of the pleura, also pleural solitary fibrous tumour, is a relatively common chest wall tumour.
The solitary fibrous tumour in general is dealt with in the solitary fibrous tumour article.
General
- Uncommon overall[1] ~ 800 cases reported.[2]
- Common for the anatomical site.
- Usually benign ~ 80% of the time.[2]
- Slow growing.[1]
- Elderly.
- May be large - impair respiratory function.[3]
- May be associated with hypoglycemia.
- Known as Doege-Potter syndrome.[4]
Gross/radiology
- Chest wall mass.
- May be "large".[2]
Microscopic
Features:
- Spindle cells - usually bland cytology.
- Patternless pattern.
- +/-Ropy collagen.
- Staghorn vessels.
Suggestive of malignant:[3]
- Mitotic rate >4/10 HPF.
- Definition suffers from HPFitis.
DDx:
- Malignant mesothelioma.
- Metastatic carcinoma.
- Lung adenocarcinoma.

Features:
- CD34 +ve (19/23 cases[6]).
- Ki-67 low (<5%).[3]
- Vimentin +ve (23/23 cases[6]).
- BCL2 +ve (23/23 cases[6]).
- CD99 +ve (23/23 cases[6]).
- SMA -ve/+ve (7 +ve/23 cases[6]).
Others:
Suggested stains:[citation needed]
- CD34, CD99, BCL2, S-100, Ki-67.
