A rare case of malignant solitary fibrous tumor of the pancreas

Solitary Fibrous Tumor (SFT) of the Pancreas is a rare tumor with a recent literature review tallying only 18 cases. Only 2 cases of cytologically malignant SFT of the pancreas have been reported till date. A SFT histology shows a patternless architecture, characteristic hypercellular and hypocellular areas separated by collagen bands and branching thin walled vessels. IHC plays an important role in separating tumors with SFT like features. CD34 is positive in 90-95% of SFT although the most emerging sensitive and specific marker is STAT6. Complete surgical excision is the treatment of choice. We are reporting the third malignant SFT of pancreas and the first instance where a similar tumor recurred.
