Highlights

  • A 33 year-old woman presented with a mass in her upper abdomen.

  • Non-mobile fullness palpated in her epigastric region and left upper quadrant of the abdomen without any tenderness or abdominal guarding.

  • Pathology assessment reported a neoplasm composed of various tissues including skin, respiratory mucosa, gastrointestinal mucosa, fat, smooth muscle, hyaline cartilage, peripheral nerves and ganglions along with vast areas indicative of previous bleeding with aggregation of hemosiderin. The final diagnosis was made as a mature cystic teratoma with no evidence of malignancy or immature components.

Abstract

Background

Mature cystic teratoma is one of the most common tumors of the ovaries; however, primary retroperitoneal lesions are rare entities in adults.

Case summary

We report a case of a 33 year-old woman noticing a mass in her epigastric and left upper abdominal region without any specific signs and symptoms. Radiological evaluation revealed a retroperitoneal mass with extension from the posterior aspect of the pancreas to the pelvic cavity, composed of calcifications and cystic elements.

Conclusion

The tumor was resected through a midline laparotomy and the pathology report confirmed the diagnosis of a mature cystic teratoma with no evidence of malignancy or immature components.
