In 14 (11.29%) of the 124 patients, we found that the cortical had irregular outlines (i.e., a mono-lobulated or multi-lobulated appearance). Moreover, none of the patients showed protrusions from the cortex into the soft tissue. In these 14 cases, the cortex consistently

showed only slight focal thickening (< 4 mm, which only slightly exceeds normal thickness). Of these patients, 5 had a single extroflexion of the cortex; 6 patients had 2 and 3 patients had 3. In 6 (4.84%) of the 124 patients, the cortex showed a structural irregularity; in particular, 3 of these patients showed macro-calcification and 3 showed hyperechoic areas. The mean age of those patients with irregularities in the lymph nodes selleckchem outlines and/or cortex was slightly higher than that of patients without these irregularities, though the difference was not statistical significant. None of the patients had lymph nodes with marked focal alterations in vascularisation, yet cortical vascular signals were found in 3 of the 6 patients with cortical irregularities; these patients also showed extroflexions of the

cortex exactly in correspondence with the color-power MGCD0103 concentration Doppler signal. All patients showed fatty hilus, but 22 (17.74%) patients had at least one lymph node with a non-homogeneous or partially hypoechoic hilus. Although some recent studies have reported this pattern in non-pathological Dimethyl sulfoxide axillary and inguinal lymph nodes [11], according to other studies [3], these findings could be indicative of metastases. With respect to the patient’s medical history, no associations were found between morphological

anomalies in the lymph nodes and diabetes mellitus (reported by 10 of the 124 patients; 8.06%), recent moderate loco-regional trauma (12 patients, 9.67%), or habitual hair removal from the limbs and/or pubic region (48 patients, 38.71%). Overall, the above results show that 42 (34%) of the 124 patients had at least one morphological GSK458 molecular weight alteration of lymph nodes that were considered to be potentially suspect for metastases, independently of the size of the lymph nodes. A size of > 2 cm, which was found in more than 20% of our patients, was not associated with the presence of irregular outlines or structural irregularities in the cortex. The characteristics of the lymph nodes are summarized in Table 2.
