A case report of primary ovarian fibrosarcoma

Background: Ovarian fibrosarcoma is a rare malignant tumor that should be distinguished from benign fibrous ovarian tumors and other malignancies, as it has a predilection for early and aggressive metastasis. Case: A 52-year-old woman presented with a large adnexal mass comprised of atypical spindle cells with increased mitotic activity, high Ki-67 index, and positive vimentin staining, consistent with primary ovarian fibrosarcoma. The patient required multiple laparotomies for large volumes of recurrent, rapidly growing disease. She died 15 months after initial surgery. Conclusion: Ovarian fibrosarcoma is an important diagnostic consideration when evaluating adnexal masses. Further study is required to clarify the impact of potential prognostic factors and establish optimal management and treatment.
