Solitary fibrous tumor arising in the mesentery: a case report

BACKGROUND: Solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm usually found in the pleura, soft tissues and visceral organs. We describe one case arising in the mesentery, which is an exceptional localization. CASE PRESENTATION: A 71-year-old man was referred to our establishment for a painless hypogastric mass. Further investigation revealed a vascular tumor, which was resected en bloc. Pathological findings confirmed solitary fibrous tumor of the mesentery. CONCLUSION: This is the second case of solitary fibrous tumor of the small intestine mesentery ever reported. It was managed by en bloc resection and close follow up considering the high risk of recurrence. Investigation should be made regarding the use of adjuvant systemic therapy to improve long-term survival for these patients.
