the difference between variables was analyzed with statistical Chi square test or Fisher's when appropriate. The strength of the relationship between variables was analyzed with Pearson's r coefficient. The sensitivity and specificity of US tests were also calculated. Sixty-five malignant lesions and 39 benign lesions were identified at Doppler US. In the 34 melanomas, typical US and vascular patterns were identified depending on the thickness of the lesion and a strong correlation between the latter and Breslow index was confirmed. Doppler US is a valuable diagnostic tool for the study of skin and for pre-excision characterization of skin lesions.

The data acquired demonstrate that the eco color Doppler with high resolution can be considered a valid non-invasive tool for the assessment of morphological and quantitative degree of engraftment of autologous adipose tissue transplanted. Lipofilling is an accurate and effective choice for the correction of congenital or acquired skin disorders for its filler effect and consequent benefit for all tissue layers.

Transmural migrated retained sponges usually impact at the level of the ileo-cecal valve leading to a small bowel obstruction. Once passed through the ileo-cecal valve, a retained sponge can be propelled forward by peristaltic activity and eliminated with feces. We report the case of a 52-year-old female with a past surgical history and recurrent episodes of abdominal pain and constipation. On physical examination, a generalized resistance was observed with tenderness in the right flank. Contrast-enhanced multi-detector computed tomography findings were consistent with a perforated right colonic diverticulitis with several out-pouchings at the level of the ascending colon and evidence of free air in the right parieto-colic gutter along with an air-fluid collection within the mesentery. In addition, a ring-shaped hyperdense intraluminal material was also noted. At surgery, the ascending colon appeared irregularly thickened and folded with a focal wall interruption and a peri-visceral abscess at the level of the hepatic flexure, but no diverticula were found. A right hemi-colectomy was performed and on dissection of the surgical specimen a retained laparotomy sponge was found in the bowel lumen.
