Area of Science:

  • Oncology
  • Surgical Pathology

Background:

  • Primary abdominal extraskeletal osteosarcoma (EOS) is exceptionally rare.
  • This tumor type presents diagnostic and therapeutic challenges due to its infrequent occurrence.

Purpose of the Study:

  • To report a case of primary abdominal extraskeletal osteosarcoma (EOS) involving the greater omentum.
  • To review the existing literature on the etiology, diagnosis, pathology, treatment, and prognosis of abdominal EOS.

Main Methods:

  • Case report of a patient with primary abdominal EOS.
  • Literature review encompassing etiology, diagnosis, differential diagnosis, pathological features, treatment, and prognosis.
  • Surgical intervention via laparoscopy followed by pathological examination.

Main Results:

  • The pathological examination confirmed malignant spindle cells with neoplastic osteoid and osseous/cartilaginous components.
  • The patient experienced tumor recurrence three months post-surgery.

Conclusions:

  • Primary abdominal extraskeletal osteosarcoma (EOS) is a challenging diagnosis.
  • Early recurrence highlights the aggressive nature and need for effective treatment strategies for this rare malignancy.
