Primary mature teratoma of the left adrenal gland: a case report.

Teratoma are germ cell tumors, most frequently arising in the gonads and retroperitoneal teratomas are rare, especially adrenal teratomas. Only a few case reports have been documented in the literature so far. We report the case of a 52-year-old asymptomatic male patient who had an incidental finding of a left adrenal teratoma during an abdominal computed tomography scan; due to the large size of the tumor, he underwent laparoscopic left adrenalectomy, and histopathological examination revealed a mature teratoma of the left adrenal gland, Patient recovering well after surgery and had no recurrence after 6 months of postoperative follow-up. The preoperative diagnosis of adrenal teratoma is challenging because imaging features are usually non-specific. Minimally invasive surgical resection is the best option for diagnosis and treatment of adrenal teratoma.
