“…The differentiation between these two neoplasms in the kidney is often problematic. Although teratomas and teratoid WT may have similar histology, teratomas display unequivocal organogenesis such as stratified squamous epithelium associated with skin adnexa, intestinal mucosal epithelium surrounded by smooth muscle bundles, and neuroglial tissue associated with choroid plexus epithelium (34). In occasional cases of TWT, the serum AFP levels may be elevated.…”

Teratoid Wilms tumor is a rare variant of Wilms tumor composed predominantly of well-differentiated epithelial and/or mesenchymal heterologous elements. Like the classical Wilms tumor, this variant may also occur as a renal mass or may be found in extra renal locations. This tumor may be treated effectively by surgical resection; however, it generally fails to respond to chemotherapy. A review of the literature revealed 30 reported cases of intra renal and 5 reports of extra renal teratoid Wilms tumor. We report our experience with an additional three cases of renal teratoid Wilms tumor adding to the 30 cases previously reported.

“…Intrarenal teratomas are extremely rare [2 , 5] and only 20 case reports have been reported in the literature from 1934 to 2004. Out of these cases, only 5 had associated congenital abnormalities such as horseshoe kidney, prune belly syndrome, and duplicated collecting system [6] .…”

“…The latest renal teratoma was described by Balanji et al in 2018 where they found a mature teratoma within the renal pelvis [7] . The most common location for teratomas are as follows: 40% in sacrococcygeal region, 25% in ovary, 18% in mediastinum and neck, 12% in testis, and 5% in brain tissues [5 , 8] . Its occurrence is considered less than 5% in the abdomen [5] .…”

Teratomas commonly occur within ovaries, sacrococcygeal regions, testis, mediastinum, and intracranial regions. One of the rare sites for this tumor includes kidneys. Renal anomalies such as horseshoe kidneys with teratoma are one of the extremely rare presentations. The authors present a case of a large teratoma within a horseshoe kidney in an 8-year-old girl whose main clinical manifestation was abdominal distension. Intrarenal teratoma within horseshoe kidneys is a rare and interesting clinical entity that would require an appropriate therapeutic approach to salvage the kidneys and remove the mass.

“…In this case tumor was not arising in kidney it originated in retroperitoneum and due to extremely large size it displaced left kidney and its hilum to right side casing it appears like 'acquired crossed nonfused renal ectopia'. 10 Various renal migration anamolies are congenital such as simple renal ectopia -abnormal position of the kidney in the cranial or caudal direction on same side of origin. There are 4 different recognized types of simple renal ectopia:…”

This is a rarest of rare case of surgical resection of giant retroperitoneal teratoma in a 15 yr old female child, causing displacement of left kidney to right by its huge volume (45X30X25cm= 33750cm3), making it appear like acquired crossed confused renal ectopia. Teratomas can occur anywhere in abdomen. Ovary being most common site followed by retroperitoneum. The most common age group is <1yr of age but they can present in any age. There are various case reports describing giant teratomas of various sizes in children and adults. Largest reported size is of 35x35cm size in a 33 yr old female. The case author has operated is rare case ever reported of ‘most voluminous retroperitoneal teratoma in 15 yr old female’ with displacement of all intra-abdominal structures by its volume. Tumor was 45x30x25cm with 12kg weight. When presented patient had complaints of vague discomfort and extreme abdominal distension progressive over last 1 yr. Patient underwent surgery -Excision of tumor, which needed dissection from superior mesentric artery and vein, splenic vein, pancreas, retroperitoneum, splenic vein, diaphragm and left kidney. Left kidney was rotated to right side, causing it to appear like ‘acquired crossed confused renal ectopia’ The left kidney was safely replaced to its original position in left renal fossa. The histopatholgy of tumor was of mature teratoma with no evidence of malignancy. Patient remained symptom free and recurrence free during 5 yrs follow up. Mature cystic teratomas are benign in nature they can attain enormous size in abdomen and can displace any intrabdominal structure. Surgeons should be aware that these big tumors can be resected with preservation of displaced structures in abdomen. Careful surgery is essential for preservation of abdominal organs and to ensure quality of life of patient.
