SFT is usually diffusely and strongly positive, whereas PHAT is focally or partially positive...but I favor PHAT. The truly morphologic differential, in my opinion, is ancient schwannoma...but CD34 positivity is usually focal and in Antoni B areas.

This is a solitary fibrous tumour (STAT6+ve). I have not knowly seen a case present in the skin and I'm very grateful to Florence & George for kindly giving me sections from their case. My notes as follows:

DDx: PHAT, Solitary fibrous tumour
STAT6 +ve (99% of SFT)
Final Dx: Solitary fibrous tumour (STAT6+ve)
Primary cutaneous = rare
DDx Spindle cell lipoma, DFSP
WHO since 2013: Haemangiopericytoma = SFT
