Laparoscopic Removal of Benign Pelvic Retroperitoneal Teratoma

Abstract

Fig. 2. Laparoscopic view after enucleation of teratoma. A 31-year-old fertile woman had a pelvic mass that was diagnosed as fibroid uterus. At laparoscopy, a well defined retroperitoneal soft-tissue mass 8 cm in greatest diameter was observed in the pelvis over the right pararectal and presacral area; the uterus and both ovaries were normal (Fig. 1). Laparoscopic enucleation of the cyst wall was performed with difficulty; it contained thick, cheesy, sebaceous material and hair. Histopathologic analysis confirmed a mature cystic teratoma containing pilosebaceous elements, endocrine and apocrine glands, fat lobules, nerve fascicles, and calcification. No immature elements were present. The laparoscopic view after enucleation of the mass is shown in Fig. 2. Primary retroperitoneal teratoma is extremely rare in adults [1]. Ultrasonography can reveal the cystic, solid, or complex components of the tumor [2]. Computed tomography and magnetic resonance imaging can demonstrate the
