Mesenteric leiomyosarcoma in a pregnant woman: A case report and review of literature

Sanjay P Deshmukh, Minish Jain, Taher ChharchhodawalaIndian Journal of Cancer 2021 58(2):267-272 We herein describe a case of primary leiomyosarcoma of descending mesocolon mesentery in a pregnant woman. A 31-year-old woman was referred to our clinic for the presence of a suspicious mass (solid heterogenous lesion with lobulated margins) detected during routine obstetric ultrasonography (USG), growing throughout her term. Imaging in her third trimester showed a considerable increase in the size of the mass and was suspected to be malignancy of uterine origin. Tru-cut biopsy performed post-partum indicated leiomyosarcoma. She underwent neoadjuvant chemotherapy with six cycles of dacarbazine and doxorubicin with partial response. Subsequently, she underwent surgery, and the tumor was found to be present in sigmoid colon mesentery extending in retroperitoneum involving 5 cm of ureter. The mass was resected along with part of the colon and ureter that was involved by disease. Patient had uneventful recovery post-surgery. Considering moderate response to chemotherapy and discussion in tumor board, she was not given adjuvant chemotherapy. At follow-up of 15 months, the patient is disease-free with a normal, healthy baby.
