A rare case of anterior abdominal wall sarcoma

Background: Soft-tissue sarcomas are a varied group of rare mesenchymal malignancies that can arise at any location in the body and affect all age groups. oft-tissue sarcomas arising from the abdominal wall mostly appear as palpable mass, abdominal wall deformity, or pain that is more clinically apparent. Case report: This case corresponds to a 44 years old female patient with ulcer over anterior abdominal wall extending up to the perineum since 1 year which gradually increased in size since 6 months. CT scan of the pelvis showed a large ulcerated soft density mass lesion in the abdomino-pelvic-perineal and inguinal region on right side measuring 23cm x 17cm x 15cm in size. The microscopic features from the biopsy showed epitheloid tumor cells with high N: C ratio, myxoid changes and final impression of Undifferentiated tumor. Outcome: The patient was initially kept on conservative treatment for pain and was advised for IHC markers to plan for further management but the patient refused for the same and did not follow up lately after discharge. Discussion: Abdomen and pelvis soft tissue sarcomas constitute 25-30% of all soft tissue sarcomas, with equal incidence in men and women. Although surgery remains the principal therapy for soft-tissue sarcomas, some tumors are not amenable to surgical resection because of the location and extent of the tumor or the presence of distant metastatic disease, or due to comorbid condition. Prognosis depends on location, on malignancy grade, histological subtype, size and quality of the operative resection.
