Intraperitoneal solitary fibrous tumor

Area of Science:

• Gynecologic Oncology
• Pathology
• Surgical Oncology

Background:

• Solitary fibrous tumors (SFTs) are rare mesenchymal neoplasms.
• Pelvic SFTs are exceptionally uncommon, posing diagnostic and therapeutic challenges.
• This report details a significant abdominopelvic SFT case.

Purpose of the Study:

• To present a rare case of a large solitary fibrous tumor in the pelvis.
• To discuss the diagnostic and management approach for pelvic SFTs.
• To underscore the importance of long-term surveillance for these rare tumors.

Main Methods:

• Case report of a 32-year-old female with an abdominopelvic mass.
• Imaging studies (ultrasound, CT/MRI) to characterize the mass.
• Exploratory laparotomy for surgical resection.
• Histopathological and immunohistochemical analysis for definitive diagnosis.

Main Results:

• A 32-year-old patient presented with a large abdominopelvic mass.
• Imaging revealed a significant right adnexal mass exceeding 10 cm.
• Surgical exploration identified a 20 cm mass in the pouch of Douglas, adhered to the uterus.
• Histology confirmed the mass as a solitary fibrous tumor.

Conclusions:

• Solitary fibrous tumors of the pelvis, though rare, can present as large masses.
• Complete surgical resection is the primary treatment modality.
• Long-term follow-up is crucial due to the potential for aggressive behavior and recurrence.
