Introduction: Primary retroperitoneal mature cystic teratomas (PRPMCT) are uncommon in adults. They typically occur in infants under six months old and young females. So far, some limited case reports have been documented in the literature. This case report presents a rare case of an adult patient with PRPMCT aged over 30 years. Case Presentation: The patient was a 34-year-old female with PRPMCT in the site of the left adrenal gland and abdominal discomfort. Computed tomography (CT) scan revealed a 66 mm hypodense lesion with fat attenuation and calcification in the left retroperitoneum. Laparotomy with resection of the retroperitoneal (RP) lesion was done. Gross examination showed a solid multicystic mass measuring 8x6.5x6 cm. Histopathologic examination revealed a neoplastic tissue composed of mature osseous and cartilaginous tissue associated with stratified squamous epithelium and lumens lined by ciliated columnar epithelium, and the diagnosis was mature cystic teratoma. The patient had an uncomplicated postoperative course without recurrence after seven months of follow-up. Conclusions: PRPMCT in adults is extremely rare. RP metastasis of primary gonadal teratoma and non-functioning adrenal tumors should be excluded first. Due to the diagnostic difficulty of posterior peritoneal teratoma with radiological imaging and its risk of malignancy, surgical resection would be the most effective diagnostic and therapeutic option. Complete resection of the mass is important to judge the existence of immature and solid components that require a long-time follow-up because of the increased risk of malignancy.

Objectives:Primary retroperitoneal mature cystic teratomas are exceedingly uncommon in males aged 50 years and above, and only seven cases have been reported in the literature so far. They usually occur in infants less than 6 months and young females. The aim of this article is to present a rare case of a 51-year-old male with a primary retroperitoneal mature cystic teratoma located in the right infrarenal area adherent to the psoas muscle and to discuss a historical literature review.Methods:An incidental hypoechoic, solid appearing 8.2 × 7.6 × 7.8 cm3 mass arising off the inferior pole of the right kidney was found on abdominal ultrasound during evaluation for a history of alcoholism. Computerized tomography (CT) scan revealed small calcifications in the lower part of the cystic mass. Laparotomy with excision of the retroperitoneal mass was performed.Results:On gross examination, the specimen consisted of a cyst filled with pale yellow greasy material with entrapped hair. Histopathologic examination revealed a dermoid cyst with focal chronic inflammation, dystrophic calcification, and foreign-body giant cell reaction.Conclusions:Retroperitoneal mature cystic teratoma in an older male is extremely rare. Primary gonadal teratoma with retroperitoneal metastasis should be excluded first. Evaluation of age and location of tumor are critical for its prognosis. Complete excision of tumor is necessary to evaluate whether there are immature and solid elements which need long-term follow up due to the increased risk of malignancy.
