Ovarian teratoma with peritoneal gliomatosis and elevated serum alpha-fetoprotein

An adolescent girl, had a grade 1 immature teratoma combined with a rare manifestation of glial peritoneal implants of grade 0. A unilateral salpingo-oophorectomy was performed. Alpha-fetoprotein levels, which were elevated before the operation, returned to normal. The patient has been symptom-free for more than three years after the surgical treatment. Repeated normal assays for alpha-fetoproteins can serve as a guide to a projected favorable course. The World Health Organization grading of the teratoma is listed and pertinent medical literature is briefly discussed.
