RESUMEN
Rosai-Dorfman disease or sinus histiocytosis of the lymph nodes is a rare, idiopathic, and benign disorder. Painless lymphadenopathy is the most frequent systemic presenting symptom and involves the cervical region in up to 90% of the patients. Extranodal involvement is less common and can represent the initial or the only presentation of the disease. We present the ultrasound and sonoelastographic features of a case of extranodal, pure cutaneous Rosai-Dorfman disease involving the breast, in which the breast involvement led to the final diagnosis. We discuss the ultrasound appearance of the disease (on B-mode, Doppler ultrasound, and sonoelastography) with a review of the literature and the different morphological patterns encountered in extranodal and cutaneous involvement.

Ultrasonography represents the method of choice in the investigation of the female pediatric pelvis. While the investigation itself poses no real challenges, an accurate interpretation of the images must take into consideration the specific features of the ovaries and uterus at certain ages. The present essay aims to demonstrate the normal appearance of the female pelvis and the changes that occur during the various stages of development as well as the some of the most common pathological conditions.

Urinary collecting system duplication is a congenital anomaly and can associate various types of urinary tract pathologies. Authors will illustrate by cases some of associated anomalies such as ureterocele, extravesical ectopic ureter, vesicoureteral reflux or reflux nephropathy; one case presented an association between posterior urethral valve and bilateral collecting system duplication.
