Abstract
Introduction: Undifferentiated pleomorphic sarcoma (UPS), formerly known as malignant fibrous histiocytoma, is a high-grade soft tissue sarcoma arising from mesenchymal stem cells. UPSs are rare and account for about 5% of all soft tissue sarcoma. UPSs arising in the head and neck are especially rare, comprising 1-3% of all UPSs.
Case presentation: In this report, we describe 2 cases of intraocular UPS. Both cases concern 68-year-old males: one developing a UPS in an eviscerated socket after a chronic fibrinous inflammation and the other years after ocular trauma.
Conclusion: Our cases may support the hypothesis of chronic inflammation playing a role in sarcoma formation as they are characterized by a longstanding history of (surgical) trauma with signs of chronic inflammation and phthisis bulbi.
