Giant non-functioning adrenocortical carcinoma: an unusual tumour presentation

Adrenocortical carcinoma is a rare tumour with incidence of 1 per million all over the world. Age distribution is bimodal with peaks occurring at 5-20 years and 40-50 years. Tumours greater than 9 cm commonly involve inferior vena cava (IVC) or right side of heart. 80 percent of the carcinomas are functional. We describe a case report of a rare tumour of a non-functioning adrenocortical carcinoma in a 40 year old female having incidence of 0.5/million world over with no extra-adrenal spread at presentation without IVC or right heart involvement in spite of having a large size of 12 cm. Patient underwent successful surgical extirpation with adjuvant radiotherapy with regular follow ups and disease free survival since the surgery. It is imperative to determine hormone levels in symptomatic and asymptomatic patients with adrenal masses. The possibility of adrenocortical carcinoma should not be ruled out in a functioning/non-functioning tumour. All solid incidentalomas on computed tomography (CT)/magnetic resonance imaging (MRI) greater than 5 cm in size should be removed surgically with adjuvant therapy consideration after histopathological reporting.

Large retroperitoneal dermoid cyst in a 55 year old lady: a rare case report

Retroperitoneal cysts are usually rare asymptomatic lesions but may present with unspecific symptoms depending on the size, location and complications such as hemorrhage, infection, or rupture. A 55-year-old lady presented with complaints of non-obstructed umbilical hernia. CT scan of abdomen and pelvis was done suggestive of a large cystic non-enhancing thin walled lesion of size 27×15 cm in right lumbar region. Intraoperatively, there was a large mesenteric cyst from retroperitoneum of size 25×15 cm, extending from right iliac fossa up to right hypochondrium. A confirmatory diagnosis of dermoid cyst was made following histopathology. Retroperitoneum is a rare site for dermoid cyst. Retroperitoneal cysts which develop within the retroperitoneal space are rare intra-abdominal tumours with an incidence of 1 per 1,40,000. The incidence of recurrence for retroperitoneal cysts is higher than with other forms of cysts because their proximity to major blood vessels and other organs makes them difficult to completely excise. Surgical resection is indicated to establish a diagnosis and prevent eventual complications. Complete excision of tumour is necessary due to the risk of malignancy. After complete surgical resection the 5 years survival rate is nearly 100%.
