A rare case of aggressive uterine leiomyosarcoma: a case report

Uterine leiomyosarcoma is a rare aggressive uterine malignancy that arises from a smooth muscle of the uterus which accounts for 2-5% of all uterine malignancies. Definitive treatment is surgery with a high rate of recurrences. Our patient presented with lower abdominal pain and mass per abdomen which was diagnosed to be uterine leiomyosarcoma. A 56-year-old woman of East Indian origin presented with abdominal pain and a huge rapidly growing suprapubic abdominal mass with an almost monthly doubling. Her CA 125 and Lactate dehydrogenase (LDH) level was elevated and Computed Tomography (CT) scan showed a large irregular-shaped abdominopelvic solid heterogeneously enhanced lesion with focal central hyperdensity and areas of necrosis causing mass effect. A primary cytoreductive surgery was performed and the histopathology report confirmed the diagnosis of uterine leiomyosarcoma. A combination chemotherapy of six cycles was given to prevent recurrence. No recurrence was detected during her more than two years follow-up period. As the cases are rare in nature, screening is impractical. Hence, the diagnosis of uterine leiomyosarcoma is done by histopathologic examination after surgery.
