PURPOSE
Although surgical therapy for testicular tumors (TT) is often radical orchidectomy, tumor resection with preservation of healthy testicular parenchyma has been proposed. This study herein reports a 20 year single center experience applying testicular sparing surgery (TSS) as a primary operative strategy in pediatric patients. A systematic literature review summarizes the utility and outcomes of TSS in appropriately selected patients.
METHODS
Pediatric patients with TT who underwent TSS between 1997 and 2018 were studied. TSS was indicated if patients presented evidence of adequately spared healthy testicular parenchyma on preoperative ultrasound and negative serum tumor markers. A systematic review of the literature was also performed.
RESULTS
12 cases met full inclusion criteria with 10 of 12 subjects in the prepubertal age group. Follow-up was 73 months (range 18-278 months). Only a single male patient (GSCCT) presented with early recurrence and orchidectomy was then performed. No cases of postoperative testicular atrophy were identified. Sexual maturation (Tanner stage) expected for age in each patient was documented. Review of the literature identified 34 published studies including 269 patients (94% prepubertal). Pathologic lesions here were mainly mature teratoma(s)-(62%) with a follow-up period of 4 years. Recurrent tumors were observed in only three patients (1.1%) notably two Leydig Cell Tumors and one Teratoma. Testicular atrophy reportedly occurred in only one single case (0.37%).
DISCUSSION
TSS is a feasible alternative to radical orchidectomy in pediatric male patients with localized TT and negative tumor markers. Long term follow-up is essential to monitor testicular growth, puberty with sexual development and psychological male health.

Review
BACKGROUND
The aims of this report were to describe a case of ovarian adenosquamous carcinoma and to systematically review the pertinent literature.
METHODS
We describe a case in which a 57-year-old woman had stage IC ovarian cancer histologically diagnosed as adenosquamous carcinoma. We also systematically reviewed the literature using the PubMed database.
CASE PRESENTATION
Preoperative computed tomography and magnetic resonance imaging showed a tumor measuring 14 cm in diameter and containing solid areas. Tumor marker levels were as follows: CA125, 42.6 U/mL; CA 19-9, 134.1 U/mL; CEA, 0.9 ng/mL; and SCC, 1.6 ng/mL. The patient underwent multiple surgeries including total abdominal hysterectomy, bilateral salpingo-oophorectomy, pelvic lymph node dissection, para-aortic lymph node biopsy, and total omentectomy. Based on the cytological features of the ascitic fluid, the tumor was diagnosed as a squamous cell carcinoma. Histological examination of an excised specimen showed the transition of an endometrioid adenocarcinoma to a squamous cell carcinoma. There was no evidence of any teratomas or endometriosis-related features. We considered the tumor to be an adenosquamous carcinoma, with the squamous cell carcinoma component arising from the endometrioid adenocarcinoma component. After surgery, the patient underwent 6 cycles of paclitaxel and carboplatin chemotherapy. There has been no recurrence to date, 66 months after the initial treatment.
RESULTS
Histologically, the 8 adenosquamous carcinomas reported in the literature either arose from the mature cystic teratoma (4 cases) or endometriosis (3 cases) or were pure adenosquamous carcinomas (1 case). Our literature search uncovered no cases of ovarian adenosquamous carcinomas originating from endometrioid adenocarcinomas.
CONCLUSIONS
This is the first reported case of an adenosquamous carcinoma arising from an endometrioid adenocarcinoma. Because such tumors are rare, their standard management is unclear.

Neurosurgery Sep 2019Myelomeningocele (MM) is an open neural tube defect treated by pediatric neurosurgeons with prenatal or postnatal closure.
Congress of Neurological Surgeons Systematic Review and Evidence-Based Guideline on the Management of Patients With Myelomeningocele: Whether Prenatal or Postnatal Closure Affects Future Ambulatory Status.
BACKGROUND
Myelomeningocele (MM) is an open neural tube defect treated by pediatric neurosurgeons with prenatal or postnatal closure.
OBJECTIVE
The objective of this systematic review was to answer the question: What is the evidence for the effectiveness of prenatal vs postnatal closure of MM regarding short and long-term ambulatory status? Treatment recommendations were provided based on the available evidence.
METHODS
The National Library of Medicine PubMed database and Embase were queried using MeSH headings and keywords relevant to ambulatory status after prenatal or postnatal closure of MM. Abstracts were reviewed to identify which studies met the inclusion criteria. An evidence table was assembled summarizing the studies and the quality of evidence (Classes I-III). Based on the quality of the literature, a recommendation was rendered (Level I, II, or III).
RESULTS
One randomized controlled trial (Class II) and 3 retrospective cohort studies (Class III) were included as evidence. Initial ambulatory status depended on anatomic level of the neural tube defect. In the short term, prenatal closure may improve ambulatory status compared to postnatal closure. Spinal cord tethering or dermoid inclusion cyst has been associated with neurologic deterioration in infants closed in utero and after birth. Ambulation may cease in both groups over time. No long-term studies evaluated whether there is a difference in the ability to ambulate upon reaching adulthood.
CONCLUSION
Prenatal closure of MM may improve ambulatory status in the short term (Level II). Spinal cord tethering in both groups caused deterioration in the ability to walk. Evaluation and treatment of spinal cord tethering may help maintain ambulatory status (Level III). No studies evaluate whether prenatal or postnatal repair provides improved ability to ambulate upon reaching adulthood.The full guideline can be found at https://www.cns.org/guidelines/guidelines-spina-bifida-chapter-3.

Germ cell tumors are the most frequent neoplasia in young males. The aims of this study is to describe a case in which a postpuberal teratoma suffers a transformation to choriocarcinoma and metastasize to stomach. We have made a systematic review in PubMed and consensus documents to study this mismatch between the tumour, metastasis and the exception of gastric metastatic affectation. We describe three options to explain this discordance: a mixed germ cells tumour, a burned out tumour or a germ cells tumour derived from a malignant germ cell tumour precursor or different clonal strains. After made a thorough investigation we conclude that the most truly option is the last one as we extensive explain below. Once the gastric metastatic lesions are extremely rare and reach to <5%, but there are not conclusive assessments.

RATIONALE
Well-differentiated liposarcomas (WDLPS) are rare retroperitoneal tumors that can reach significant size as they can grow without constrains before becoming symptomatic. Laparotomic open radical tumor resection represents the most common surgical approach.
PATIENT CONCERNS
A mass with "fat fluid level" was found in the right pelvis of an asymptomatic woman undergoing routine transvaginal ultrasound: the preoperative diagnosis was right mature ovarian teratoma.
DIAGNOSIS
Postoperative histopathology confirmed the diagnosis of WDLPS.
INTERVENTIONS
A radical laparoscopic excision of the retroperitoneal mass with bilateral salpingectomy was performed.
OUTCOMES
Patient is free of disease at 18 months after surgery.
LESSON
Despite computed tomography scan is the gold standard technique to identify WDLPS, such neoplasms can be misdiagnosed for mature ovarian teratomas. When a retroperitoneal mass is incidentally discovered during a surgery, an open core-needle biopsy is usually performed, and appropriate treatment planned only after complete staging and final pathology are available. Instead, when tumor margins are identified, resection of an incidentally diagnosed WDLPS would benefit from laparoscopic magnification that could improve distinguishing the disease from the surrounding tissues. Therefore, laparoscopy could represent a safe and effective technique to diagnose and treat retroperitoneal diseases.
