Abstract
BACKGROUND
Dedifferentiated liposarcoma (DDLS) has a worse prognosis and occurs most commonly in the retroperitoneal region and rarely in the intraperitoneal region. Histological diagnosis was revolutionized by the combined contributions of histo-immuno-chemistry and molecular biology. Aside from surgery, there is no consensus on the optimal treatment for this chemoresistant cancer.
CASE SUMMARY
A thirty-year-old black female presented with a large painful abdominal mass occupying nearly the entire abdomen and progressive weight loss was admitted for surgery. Abdominal computed tomography showed a large heterogeneous mass of the mesentery that was sized 18 cm × 16 cm in size and had heterogeneous contrast enhancement. During laparotomy, en bloc excision of the large and multilobulated gastrocolic ligament mass was performed. The initial postoperative histopathological diagnosis was undifferentiated sarcoma. Finally, the results of immunohistochemistry and molecular biology allowed us to confirm the diagnosis of DDLS. The tumour followed an aggressive evolution with diffuse metastasis, causing the death of the patient less than 5 mo after the operation.
CONCLUSION
Dedifferentiated liposarcomas are rare tumours that typically originate in the retroperitoneum but may arise in unexpected locations.
Core Tip: Dedifferentiated liposarcoma has a worse prognosis and occurs most commonly in a retroperitoneal location but rarely in an intraperitoneal location. Complete surgical excision with a negative microscopic margin (R0) remains the ideal treatment when the tumour is still localized. Here, we report the case of a young woman with disseminated giant dedifferentiated liposarcoma of the gastrocolic ligament. This case demonstrates the poor prognosis of dedifferentiated liposarcomas. To the best of our knowledge, a giant dedifferentiated liposarcoma of the gastrocolic ligament has not yet been reported.
