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.

“…Commonly germ cell tumors arise in the gonads. [1][2][3] Teratomas belong to a class of tumors known as nonseminomatous germ cell tumor (N.S.G.C.T.). 4 Retroperitoneum is rare site of dermoid tumors (3.5 to 4% of all germ cell tumors in children) 5 in which 90% of these tumors are benign.…”

Malignant retroperitoneal teratoma in a young girl: a rare case report

Exploratory laparotomy revealed a large retroperitoneal mass of size 32x15x15cms with solid and cystic components. Tumor was located posterior to descending colon and mesocolon. Stomach and pancreas were pushed upwards and anteriorly where as left kidney was grossly ABSTRACT Of all primary retroperitoneal teratomas, less than four percent occur in children and 90% are benign. Here we report a case of malignant retroperitoneal teratoma (dermoid) in a 15 year old girl who presented to our hospital-Acharya Vinoba Bhave Rural Hospital (AVBRH). She presented with a tender, large, irregular mass with variegated consistency in the entire left side of abdomen crossing midline. Ultrasound of abdomen suggested a complex intraabdominal mass with septations and lobulations. It was not feasible to use other imaging modalities for evaluation due to poor socioeconomic status and illiteracy. Patient underwent exploratory laparotomy with tumor resection along with left kidney and part of the descending colon which was densely adhered to tumor. Histopathological examination of tumor was suggestive of immature teratoma. Post operative recovery was uneventful and patient was discharged from the institution. Tissue adherence which can be observed in both benign and malignant form of teratomas, requires extended surgery for removal of adhered organ for the completeness of surgery and good prognosis.

erm cell tumors are most commonly located within the gonads.1 Rare extragonadal locations of these tumors include the retroperitoneum, mediastinum, sacrococcygeum, and central nervous system and are considered to result from aberrant migration of germ cells from the yolk sac during fetal development. [1][2][3][4] We present transvaginal sonographic and magnetic resonance imaging (MRI) findings of a massive epidermoid cyst extending from the pelvis to the buttock. Case ReportA 28-year-old woman, para 1, presented with gluteal pain exacerbated during sitting and walking. Other than endometriosis confirmed by laparoscopy after secondary dysmenorrhea 7 years before her current presentation, her history was unremarkable. On physical examination, the patient was in no acute distress. Vital signs were normal, and her abdomen was soft and nontender. Pelvic examination disclosed a normal-sized uterus and adnexa. A symmetric soft pelvic mass approximately 6 cm in diameter was noted posterior to the uterus. A large cystic mass measuring approximately 10 cm in diameter bulging into the medial aspect of the right buttock was noted.Transvaginal sonography depicted a retroverted uterus with normal ovaries (the right containing a hemorrhagic cyst). A large heterogeneous mass located posterior to the uterus was noted (Figures 1 and 2). The patient was offered yet declined sonography of the right buttock. Magnetic resonance imaging delineated a pelvic mass with a large extrapelvic extension protruding to the medial aspect of the right buttock (Figure 3).
