[An apocrine hidrocystoma of the scrotum. A case report]. / Idrocistoma apocrino dello scroto. Presentazione di un caso.

A benign neoplastic lesion of the skin originating from cystic proliferation of apocrine secretory glands is defined as an apocrine hidrocystoma or cystadenoma. The tumor usually occurs in adults as a solitary cystic lesion; it is commonly found on the periorbital region, neck, upper torso and limbs. The case presented is unusual because of the age of the patient--cystadenoma is very rare in childhood--and the localization of the lesion. From a literature review and to the best of our knowledge, a scrotal cyst has never been previously described. Surgical excision is the treatment of choice since the lesion does not tend to recur.

Vas deferens anomalies in paediatric age.

Vas deferens anomalies have been observed with high incidence in cystic fibrosis patients, whereas the overall incidence in the general population is estimated less than 0.05%. Vas deferens anomalies are sometimes associated with renal abnormalities and they are due to a damage occurring within the first weeks of gestational age. In other cases they can be the expression of a mild form of cystic fibrosis. The authors report on 7 patients with 10 anomalies of vas deferens: 2 patients with cystic fibrosis; 3 patients with urinary tract anomalies; 2 patients with no evidence of cystic fibrosis and without urinary tract anomalies. It is suggested that every patient presenting with vas deferens anomalies and no evidence of cystic fibrosis should be further evaluated with renal ultrasound; moreover all patients without evidence of both cystic fibrosis and renal anomalies should have genetic investigations.

[A rare case of acute scrotum. Thrombophlebitis from ectasia of the left pampiniforme plexus]. / Raro caso di scroto acuto. Tromboflebite su ectasia del plesso pampiniforme destro.

The acutely painful scrotum may be due to testicular torsion, twisted testicular appendages, twisted spermatic cord or epididymitis. Most rarely it occurs as a result of a testicular trauma, orchitis, idiopathic scrotal edema, idiopathic infarction of testis and vaginalis tunica or testicular neoplasm; a spontaneous thrombosis of the spermatic vein vessels is quite unusual. A rare case of thrombosis of a dilated pampiniform plexus which occurred in a 6 year-old child is reported and its clinical presentation, diagnosis and treatment is discussed. The difficulty in making such a diagnosis is stressed since thrombosis of the spermatic vein is quite a rare entity; a conservative approach is suggested as a treatment of choice whenever a definite diagnosis is made, otherwise surgical intervention (ligation of the spermatic vein, if necessary) is required in order to rule out any other urologic emergency.

Congenital cystic mesoblastic nephroma.

Congenital mesoblastic nephroma is a relatively rare infantile renal tumor. It comprises 3-6% of renal masses in childhood and 50% during the neonatal period. Most mesoblastic nephroma occur in the newborn period, with 80% of the cases being reported within the first month of life. Macroscopically the tumor is composed of a solid mass of different sizes tending to invade the surrounding structures and renal parenchyma. The authors report a case of cystic mesoblastic nephroma of the cellular subtype, with diffuse areas of hemorrhage and necrosis. The tumor was treated by surgical excision with radical nephrectomy and the child is doing well 4 years after the operation.
