 note = {Background: Liposarcoma is the most common soft tissue sarcomas in adults, and it
typically occurs in either the retroperitoneum or extremities. However, this malignant
tumor is very rare in the female reproductive system.
Case: As 58-year-old female presented with acute abdominal pain, and computed
tomography (CT) scan detected multiple masses measuring 4-6 cm in size with a fatty
density in her adnexal region. Laparoscopic evaluation revealed tumors of the left
fallopian tube with normal left ovary. Histopathologic evaluation of the resected pelvic
tumors showed lipocytes and lipoblasts of various sizes, leading to diagnosis of
well-differentiated liposarcoma of the left adnexal region.
Conclusion: This is the first known case of a liposarcoma arising from the fallopian tube.
When a pelvic mass with fatty density that does not show typical findings of a mature
cystic teratoma is detected by either CT or magnetic resonance image (MRI) imaging,
the possibility of a liposarcoma should be considered., The Journal of Obstetrics and Gynaecology Research 34(4pt2), pp.713-716; 2008},
