Genetic Basis of Posterior Urethral Valves Inheritance.

OBJECTIVE: To highlight genetic pattern of posterior urethral valves (PUVs), we performed a genetic study on 2 siblings affected. PUVs are the most common congenital cause of lower urinary tract obstruction and an important cause of renal failure in infants (50% progress to end-stage renal disease in 10 years). PUVs occur in 1 of 5000-8000 male infants, but real incidence is arduous to determine because of the wide spectrum of possible clinical presentation. A different recurrence rate is reported in African Americans and children with Down syndrome, although usually PUVs are not found in syndromic conditions but constitute an isolated disorder. Although most cases appear to be sporadic, some reports in literature suggest a partial genetic etiology. MATERIALS AND METHODS: We report 2 brothers with PUVs. The children's mother was a healthy woman but had a history of urinary tract infections of unknown etiology. We investigated possible familial genetic anomalies using a DNA array comparative genomic hybridization technique. RESULTS: We identified 2 partial duplications in the short arm of chromosome 11 recurring in both children and mother. CONCLUSION: This finding, not previously reported to our knowledge, adds new data to support the hypothesis of the presence of a hereditary component in the occurrences of PUVs.

An Uncommon Case of Adolescent Ovarian Teratoma Incarcerated in Inguinal Hernia.

Mature cystic teratoma is the most frequent benign ovarian neoplastic lesion in adolescents and is generally composed of fully differentiated tissue arising from multipotential three germinal layers. It accounts for approximately 50% of benign ovarian tumors in childhood. Rarely, a bilateral, synchronous, or metachronous presentation can be observed, supporting a conservative approach as the first surgical approach. We report a case of an ovarian mature cystic incarcerated in indirect inguinal hernia in a 15-year-old girl undergoing ovary-sparing surgery. To our knowledge this is the first case of such lesion incarcerated in an inguinal hernia reported in literature.

Solitary Myofibroma of the Bladder Trigone in a 3-Month-Old Patient: First Case Report.

Visceral solitary myofibromas are uncommon in childhood. We report a case of a solitary asymptomatic visceral myofibroma of the bladder trigone occurring in a 3-month-old boy. Once malignancies were ruled out by cystoscopy, radical excision was performed in order to avoid any potential impairment of bladder dynamic. Postoperative course was uneventful and patient was discharged on day 3 after surgery. After 36 months of follow-up, the patient is toilet-trained and remains well; bladder function is normal.

Splenogonadal Fusion: A Genetic Disorder?-Report of a Case and Review of the Literature.

Splenogonadal fusion is a rare congenital anomaly in which there is fusion between the spleen and gonad, epididymis or vas. We treated a patient with scrotal mass. A discontinuous fusion between the spleen and epididymis was found: after frozen section mass was excised sparing testis. Although rare, the splenogonadal fusion should be considered in the differential diagnosis of scrotal masses in children, and orchiectomy should be avoided. Moreover, examination of siblings showed a brother affected from accessory spleen. This finding, not reported previously to our knowledge, suggests a possible familiarity of this disorder.
