Primary Pleomorphic Liposarcoma of Fallopian Tube with Recurrence: A Case Report and Review of the Literature

BACKGROUND: Liposarcoma, which develops in adipose tissue, is one of the most common soft tissue sarcomas. It appears mostly in the lower limbs, particularly in the thigh and limb girdles, followed by the upper extremities, thoracoabdominal wall, and the internal trunk and retroperitoneum. Pleomorphic liposarcoma (PLS), a rare subtype of liposarcoma is considered a highgrade malignancy. CASE PRESENTATION: We present a case of primary PLS in the left fallopian tube of a 47-year-old female. Ten months previously, she was diagnosed with PLS of the left fallopian tube in another hospital and had a wide excision of left fallopian tube mass, including total abdominal hysterectomy and bilateral salpingo-oophorectomy for left fallopian tube PLS. Presently, she has developed a recurrence and metastasis of PLS in the pelvic and abdominal cavities. CONCLUSION: This may be the first case of primary fallopian tube PLS, wherein the prognosis of this patient was poor due to the high-grade malignancy of PLS.
