Children's Hospital with an 8-day history of abdominal cramping, pain, and bile-stained vomiting. During the past 6 months he had experienced episodes of abdominal distention, constipation, and bile-stained vomiting and 1 episode of hematemesis and rectal hemorrhage 3 days before his admission. He weighed 37 kg; although his abdomen was not distended, the upper abdomen was tender, with normal bowel sounds and no palpable mass. The results of laboratory examinations were all normal. An abdominal radiograph did identify an abnormally dilated loop of the small bowel. Investigations

Teratomas are neoplasms of the embryonic tissues that typically arise in the gonadal and sacrococcygeal regions. Primary adrenal teratoma are extremely rare and only few cases were published in literature. Teratomas contain more than one embryonic germ cell layer, mostly elements derived from ectoderm and least frequently from endoderm. Though these tumors are mostly benign, malignant transformation may occur. Treatment includes surgical removal. We report a rare case of a primary mature retroperitoneal teratoma in an infant with liver metastasis. Imaging modality CT and MRI were useful in diagnosis. The diagnostic and therapeutic challenges of dealing with such a case have been discussed and the literature reviewed.

Early diagnosis of ovarian tumours in children and adolescents is important. Since most of these tumours are benign, surgical treatment should be conservative to minimise the risk of subsequent infertility, while the treatment of malignant tumours should include complete staging, resection of the tumour, postoperative chemotherapy when indicated, to give the patient a chance for future childbearing.
