Summary
A rare retroperitoneal malignant fibrous histiocytoma (MFH) invaded the colon, leading to rectal bleeding. Pre-operative diagnosis was challenging due to the atypical presentation of severe lower gastrointestinal bleeding.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Malignant fibrous histiocytoma (MFH) is a rare soft tissue sarcoma.
- Retroperitoneal tumors can present with vague or atypical symptoms.
- Gastrointestinal bleeding necessitates thorough diagnostic evaluation.
Observation:
- A case of retroperitoneal malignant fibrous histiocytoma (MFH) invading the colon is presented.
- The patient exhibited profuse fresh bleeding per rectum, an unusual manifestation for this tumor location.
- Pre-operative diagnostic challenges were significant due to the atypical presentation.
Findings:
- The primary challenge was differentiating the retroperitoneal MFH from other causes of lower gastrointestinal hemorrhage.
- Histopathological examination confirmed the diagnosis of malignant fibrous histiocytoma.
- The tumor's invasion into the colon was the direct cause of the severe bleeding.
Implications:
- This case highlights the importance of considering rare retroperitoneal neoplasms in the differential diagnosis of unexplained gastrointestinal bleeding.
- Advanced imaging and endoscopic techniques may be required for accurate pre-operative diagnosis.
- Early recognition and diagnosis are crucial for effective management and improved patient outcomes in retroperitoneal tumors.
