A case of malignant schwannoma of the larynx in a 9 year old boy is reported. The lesion recurred 29 months later with the same histological pattern. The malignant peripheral nerve sheath tumours of the larynx are rare and are almost exceptional in paediatric age. The Authors discuss the main differential diagnosis of spindle cell paediatric tumors of the laryngeal region.

The diagnostic usefulness and practical possibilities of mass X-ray screening in lung cancer is examined. On the basis of the literature and personal experience, the conclusion is cautiously pessimistic, in agreement with what has recently been stated by Lemoine, Corda and others.

The Authors describe the case of an immunologically healthy 14 year old boy presenting a hepatic infection with multiple abscesses. This case is of particular interest because of its rarity in Pediatrics. Probable etiologies, pathogenic mechanisms and treatments are discussed. The Authors underline the usefulness of ultrasonography as a diagnostic tool and as a non-invasive means of following the course of the disease.
We compared the results, by prenatal ultrasonography, effected on 2592 foetus at the 15th-25th-35th weeks of gestation with the ones, made by postnatal ultrasonography, effected the 5th day of life on 2539 infants born from pregnancies previously monitored. We considered the obstructive and not obstructive malformations. The prenatal ultrasonography put in evidence 19 cases of urological pathology, which is 0.75%. The postnatal research established the truth of 14 cases, which is 0.55%; 7 cases underwent a precocious surgical operation. Percentage of positive false is 0.2%. The postnatal ultrasonography made evident 30 cases which can be considered pathological: 25 uropathy obstructive cases and 5 uropathy not-obstructive cases; 3 of them underwent precocious surgical operation. The result is 44 pathological cases (1.74% of infants). We also considered an heterogeneous group of non-nephro-urological anomalies (0.47%), a casual medical report of this research; in particular, 10 cases of surrenal hematoma and 1 case of neuroblastoma. The Authors remark that it's useful to complete the prenatal ultrasonographic research with another postnatal ultrasonographic research, particularly in the nephro-urological pathology; and they hope this system can be much more diffuse.
