Adrenal lipomatous tumour is a group of adrenal tumours with a significant component of adipose tissue. According to the current World Health Organization (WHO) classification of tumours of endocrine organs, adrenal myelolipoma is the only entity amongst the group of tumours being described. In the literature, other more recently documented adrenal lipomatous tumours included 24 lipomas, 32 teratomas and 16 angiomyolipomas. Rare fatty tumours of the adrenal gland comprised liposarcoma, hibernoma, adrenocortical tumours with fat component and rare adrenal tumours with fat component. Myelolipoma comprises approximately 3% of primary adrenal tumour. It is noted more commonly in females and in the right adrenal gland. Approximately 40 bilateral myelolipomas were reported. The tumour is most frequently recorded in patients between fifth and seventh decades of life. Adrenal lipomas are often seen in males and in the right adrenal gland. They were commonly noted in patients in the sixth decade of life. The diagnosis could only be possible on examination of the surgically removed specimen. Adrenal teratomas were more common in females and with a bimodal age distribution. Slightly over 60% of the patients with adrenal teratoma are symptomatic. Adrenal angiomyolipomas were often symptomatic, more common in females and in the fifth decades of life. To conclude, adrenal lipomatous tumour is uncommon. They are often benign and non-functional. It is important to recognize the features of this group of lipomatous tumours in the adrenal gland as they are being detected on increasing incidence as a result of the wide-spread use of modern imaging modalities.

Background: Extra-gonadal teratomas are rare tumors in Pediatric surgical practice. We studied the teratomas of atypical sites attended in our tertiary care center. Aim: Aim of the study was to find out the incidence of pediatric teratomas in atypical sites, clinical presentation and histological variation. Material and Methods: Over 15 years (January 2005 to December 2020), 29 cases of pediatric teratomas in atypical sites were studied. These sites included neck (number-one), retroperitoneum (number-fourteen), adrenal gland (number-two), renal (number-two), gastric(number-three), pancreas (number-one), pulmonary (number-one), floor of the mouth(number-one), oral (number-two), abdominal wall (numberone) and the mesentery (number-one). Patients were treated in the Department of Pediatric Surgery and specimens were reviewed in the Department of Pathology. Age, sex, clinical presentation, investigations (all patients had complete blood examination and alpha-fetoprotein) and imaging (USG of the local part and CECT as guided by the organ of involvement). Results: 29 pediatric teratomas in uncommon sites were reviewed. Out of 14 cases of retroperitoneal teratoma, three were immature. Cervical teratoma in a neonate was mature. Three cases of gastric teratomas were reported as mature. Two cases of adrenal teratomas also showed the histological features of mature teratoma. Renal teratomas (two) were benign. One each of pulmonary teratoma, pancreas and floor of the mouth were reported as mature. Two patients presented with oral teratoma were reported as mature teratomas. One patient had teratoma arising from the abdominal wall and was resected completely (mature teratoma). Teratoma arising from the mesentery also underwent complete resection. Conclusion: A small percentage of Pediatric teratomas occur in atypical sites. In our series, retroperitoneal tumors were predominant. Early surgical excision is the treatment of choice. Malignant change is known to occur in Pediatric teratoma and the patients need long term follow-up.

“…Teratomas are uncommon congenital tumours which may or may not always arise from all three primordial germ cells (ectoderm, endoderm and mesoderm), Radiological evaluation are not precise in showing the origin of the retroperitoneal teratomas [ 2 ]. Teratomas found extra gonadal account for 15 % of all teratomas, while retroperitoneal site being the least site for teratoma 1–11 % and the extremely rare adrenal teratoma is less than 4 % of the Retroperitoneal teratomas [ 3 , 18 ].…”
