PED-11: Embryonal Rhabdomyosarcoma of the Urachus Presenting as Acute Abdomen: A Case Report

scopic gonadectomy did not affect subsequent laparoscopic assisted vaginoplasty (2). Conclusions: Laparoscopy with gonadal assessment is a useful diagnostic adjunct in complex cases of DSD when Y chromosomal material is found on the karyotype. Laparoscopic gonadectomy can be performed alone or with other indicated procedures (clitoroplasty, vaginoplasty) as an outpatient with minimal morbidity. We advocate early laparoscopic evaluation, and in appropriate cases, gonadectomy for patients with DSD and Y chromosome containing karyotype. This is based on our data showing gonadal tumors in children as young as 18 months.

Materials and Methods: We performed a retrospective review of all testicular tumors treated in two pediatric hospitals during the last 7 years (Jan 2001 to Dec 2007). We examined more closely those

treated with conservative surgery (tumorectomies and partial orchiectomies), their preoperative investigation, indications for surgery and outcome. All had preoperative ultrasound, and tumors markers ultrasound and clinical examination were used for follow-up. Results: Of 27 primary testicular masses, 13 were treated with testicular sparing surgery, 7 mature teratomas, 4 epidermoid cysts, 1 Leydig cell nodular hyperplasia and 1 Sertoli cell tumor. Mean age at treatment was 8.5 years, being the youngest cystic form of teratomas. The age range was from 4 months to 13 years old. Eleven boys presented with a testicular mass without pain; one presented with mild pain for 3 weeks prior to diagnosis (Sertoli cell tumor), and the last was an incidental finding during ultrasound for a contralateral varicocele. All had intratesticular mass in ultrasound and negative tumor markers (alpha-fetoprotein and HCG). They were treated by sparing procedure with intraoperative biopsy that showed no malignant lesions and were discharged the same or the following day. At mean a follow-up of 4 years, there was no recurrence. Post-operative examination and ultrasound were normal in all 13 cases. Conclusions: In our series we had a similar number of “benign” vs. “malignant” intratesticular masses. The first can be treated safely with conservative surgery, with intraoperative biopsy, with excellent results and conservation of testicular tissue. Pediatric testicular tumors differ from the adult cases, and we must bear this in mind when treating.
