[Benign solitary fibrous tumor of the pancreas: a rare location of extra-pleural fibrous tumor. Single case report and review of the literature].
OBJECTIVE
Extra pleural solitary fibrous are very rare, but occasionally they appear in extraserosal soft tissues or parenchymatous organs, where their diagnosis is often a challenge. In this report we describe the case of a patient with a single primary solitary fibrous tumor of the pancreatic head with a review of the literature.


RESULTS
A 62 years old woman underwent a Traverso-Longmire procedure in November 2004. Sixteen months after resection there is no evidence of recurrence. The tumour showed immunoreactivity for CD34, CD99, bcl-2, vimentin and smooth muscle actin. MIB-1 proliferating activity was < 5%.


CONCLUSIONS
Extra pleural solitary fibrous tumor are often benign lesions. In the pancreas only 2 cases have been described so far. Other mesenchymal tumours that may occur in the pancreas include leiomyosarcoma, tumours of the peripheral nerve sheath, fibrous histiocytic tumours and rare vascular tumours. The differential diagnosis is mainly based on immunohistochemistry. The surgical approach is fundamental for the treatment of solitary fibrous tumour.
