Uterine leiomyosarcoma is an uncommon tumour accounting for 1% of all uterine malignancies These are aggressive tumors with common sites of metastasis as peritoneal cavity, omentum, lung, pelvic lymph nodes, etc .Here we report a rare case of metastasis of uterine leiomyosarcoma to the anterior abdominal wall. A 36 year old patient with a history of supra-vaginal hysterectomy for uterine leiomyosarcoma 10 years back, presented with a lump in lower abdomen since 4 months. CECT pelvis suggested 7.7 *6.1 cm neoplastic mass in the anterior abdominal wall involving rectus abdominis and adjacent abdominal muscles. Tru-cut biopsy confirmed leiomyosarcoma. Repeat CECT after chemotherapy showed marginal reduction in the size. She underwent wide local excision of mass with a resulting defect of 20 x 15cm & abdominal wall reconstruction with a composite mesh & tensor fascia lata flap on 17/7/18.Final histopathology report confirmed the diagnosis. PET CT done on 21/9/18 revealed no residual disease.
