Multiple Primary Dedifferentiated Liposarcoma of the Jejunal Mesentery: A Case Report and Review of Literature

Liposarcoma arising primarily from the intestinal mesentery is a rare malignancy. Malignancy is said to be synchronous when there is occurrence of two or more tumours that have not spread from a common site or recurred and show no evidence of metastasis. Multiple synchronous primary liposarcoma of the mesentery is a very unusual clinical finding. Here, we report a rare case of synchronous multiple primary dedifferentiated liposarcoma of jejunal mesentery in a 36-year-old female patient. Radiological investigations aided in making a provisional diagnosis of an ovarian malignancy. A staging laparotomy was performed and general surgeon's help was sought due to the presence of three separate jejunal mesenteric masses of sizes 8x6 cms, 6x6 cms and 25x20 cms respectively. Complete excision of mesenteric masses with one feet of involved jejunum was done and a jejuno-jejunal anastomosis made. The histopathology report was indicative of multiple dedifferentiated liposarcoma of jejunal mesentery. Postoperatively patient received Doxorubicin, Dacarbazine and Ifosfamide based adjuvant chemotherapy in view of poorly differentiated tumour. Patient remains tumour free for the last 12 months of follow up.
