Abstract
Teratoma can be defined as a true neoplasm that contains tissues that either are foreign
to the primary site of origin or are histologically diverse and represent more than
one of the embryonic germ layers. A 20-year-old female patient presented with chief
complaints of swelling in the right upper abdomen since childhood and back pain for
the past 4 years. Per abdomen, examination revealed a lump of around 15 cm in size
in the right hypochondrial region extending to the epigastric region. Contrast-enhanced
computed tomography abdomen revealed a 14.3 × 14.1 × 17.4 cm well-defined heterogeneously
hypoattenuating nonenhancing complex cystic mass with focal areas of calcifications
and fat attenuation in retroperitoneum. The patient was taken up for exploratory laparotomy
and a tumor was found in the retroperitoneum, retrocavally and was excised with due
care. Histopathological examination features were suggestive of mature cystic teratoma.
The postoperative stay was uneventful.
