Laparoscopic simultaneous resection of bilateral giant primary mature retroperitoneal teratoma of the adrenal region: A case report

Jianqing Wang et al. Medicine (Baltimore). 2019 Nov.

Abstract

Rationale: Giant mature retroperitoneal teratoma of the adrenal region is quite rare in adults. In most cases, open adrenalectomy is required to ensure complete resection. We describe a case of bilateral giant primary mature cystic teratoma in the region of both adrenal glands in a 22-year-old female patient.

Patient concerns: A 22-year-old female patient was admitted to our hospital with no complain after detecting to have 2 giant well circumscribed masses in a routine investigation.

Diagnoses: She was diagnosed with bilateral giant primary mature retroperitoneal teratoma of the adrenal region.

Interventions: The patient underwent en bloc excision of the mass through laparoscopic simultaneous resection.

Outcomes: We carefully separated and retained most of the adrenal tissue on both sides during surgery. Pathology reported mature teratomas. Eleven days after operation, the patient made uneventful recovery and left the hospital without any complication.

Lessons: Preoperative imaging and histologic analysis confirmed mature retroperitoneal teratomas. It is feasible to treat such giant benign tumors by laparoscopic simultaneous resection.
