Intra‐abdominal omental mass as a desmoplastic round cell tumor: A rare case report.

Key Clinical Message: Desmoplastic round cell tumor, though rare, must be taken into consideration as a differential diagnosis, thus aiding in early evaluation and changing the trajectory of the natural history of the disease condition, and improving the prognosis of patients. Desmoplastic small round cell tumor is a rare, aggressive tumor of mesenchymal origin with an incidence of 0.74 cases per million. We present a young adult with a periumbilical mass who was diagnosed as a desmoplastic round cell tumor and later was treated with exploratory laparotomy and resection of the tumor with no recurrence during a 6‐month follow‐up period.
