[Meconial hydrocele].

Presentation of one case of meconial hydrocele, a very infrequent disease that should be taken into account in all newborns presenting intrascrotal mass. Ultrasonography performed to a 29 year-old female during the 36th week of pregnancy, demonstrated in the fetus the presence of an enlarged right hemiscrotum with homogenous material inside, which was diagnosed as an intrascrotal haematoma due to a likely intrauterine spermatic cord torsion. After eutocic delivery, within one month from birth the newborn developed signs and symptoms which were compatible with acute scrotum and the emergency surgical exploration showed meconial hydrocele secondary to patency of peritoneal-vaginal duct with associated inguinal hernia. The causes, forms of presentation, differential diagnoses and therapeutical options of meconial peritonitis, a rare condition with favourable evolution in most cases, are analyzed showing that, under certain circumstances, treatment is controversial.

[Vesical endometriosis after cesarean section: diagnostico-therapeutic aspects].

Endometriosis is a benign condition with an aggressive behaviour defined by the presence of ectopic endometrial tissue, outside the uterus. It occurs in 15-20% women with child bearing potential. Most commonly it affects organs such as the ovaries, uterine ligaments, fallopian tubes, rectum and the cervico-vaginal region. Involvement of the urinary tract, however, is rare. It can be seen in just about 1% cases, vesical location being the most frequent of these presentations (84% cases). We describe one case of vesical endometriosis that developed after a cesarean section. The intra-operative findings confirmed the existence of infiltration of the detrusor muscle and the vesical mucosa by endometrial tissue from the area of the uterine incision. A discussion of the different diagnostic and therapeutic options is also included.

[Bladder pseudosarcoma in pediatrics: clinico-pathological features and treatment].

OBJECTIVES: To review the most common clinical signs and symptoms of inflammatory pseudotumor of the bladder in children and to distinguish this benign lesion from malignant neoplasms such as rhabdomyosarcoma and leiomyosarcoma. METHODS: Two cases os pseudosarcomatous tumor of the bladder in children are described. In the first patient, the tumor had appeared spontaneously in a 9-year-old boy. The second had developed in a 6-year-old girl and was considered to be reactive to prior surgery. The literature is reviewed and data from 16 cases of inflammatory pseudotumor of the bladder in patients under 16 years of age are also presented. RESULTS: The mean age at presentation was 8 years. The male-to-female ratio was 3:1. Hematuria (56%), dysuria (37%) and abdominal pain with a palpable mass (18%) were the most commonly described clinical manifestations. Tumor size ranged from 3 to 10 cm and they were frequently located in the lateral walls and base of the bladder. Histological analysis showed an inflammatory pseudosarcomatous reaction. Immunohistochemical analysis showed moderate staining for vimentin, mild staining for focal muscle actin and negative for keratin and S-100 protein. Patients were treated by local resection (7 pts), partial cystectomy (5 pts), radical cystectomy (2 pts) and pelvic exenteration (2 pts). The mean follow-up was 34 months. All patients that had been followed (14/16) were reported to be free of disease with no evidence of recurrences or metastases. CONCLUSIONS: Inflammatory pseudotumor of the bladder is an unusual benign tumor that is very rare in children. Long-term follow-up confirms the benign nature of the lesion and conservative management is therefore advocated. However, given its histological similarity to malignant tumors, a close follow-up is recommended.
