Solitary fibrous tumour of pleura

Case contributed by Dr Jeremy Jones

Large left basal pleural mass adjacent to the diaphragmatic surface.

CT confirms the large pleural mass at the left diaphragm with internal calcification.

Clinical Details:

Probable fibroma. Cacification on CT. Large left basal mass

Macroscopic Description:

Three cores, the largest 5x1x1mm.

Microscopic Description:

One of these cores consists of vascular collagenous tissue in which there is a dispersed population of cytologically bland spindle-shaped cells that are immunopositive for CD34 and bcl2 but immunonegative for AE1/3, MNF116, CD31, calretinin, SI00, SMA, desmin and caldesmon.

These appearances are those of a solitary fibrous tumour (also known as submesothelial fibroma).
