Abstract
OBJECTIVES To review our radiological experience in metaplastic carcinoma together with the clinical and histopathologic findings. METHODS AND MATERIALS Eight cases of histologically confirmed metaplastic carcinoma of breast were reviewed. Imaging findings from US, mammography and MRI, and immunohistochemistry results from preoperative biopsy were assessed. Conventional prognostic factors, chondral differentiation markers, striated and straight muscle markers, neural markers, cytokeratin, vimentin and intermediate filaments were determined. RESULTS Eight patients aged ranged from 41-72 years. Metaplastic carcinoma presented as a palpable nodule in five cases, as a nipple retraction in ones case, and was discovered as an incidental mammographic finding in two. Mammographic appearance was a round, high-density nodule, measuring 10-50 mm, with variable margins in seven patients. One had architectural distortion. In three there were calcifications. Skin and nipple retraction appeared in one. On sonographic examination nodules were ill defined and showed low heterogeneous echogenicity. On MRI, T2-weighted images showed a relatively well-defined mass with high signal intensity. In the dynamic study, all showed contrast uptake, with signal-time intensity curves similar to those of infiltrating carcinoma of the breast. Histopathologic study found one squamous-cell, one sarcomatous, three chondroid, one giant-cell, one spindle-cell, and one acantholytic carcinoma, all of which were of high histologic grade. CONCLUSIONS Metaplastic carcinoma should be included in the differential diagnosis of a nodule presenting with high density and variable margins on mammography, low heterogeneous echogenicity and ill defined margins on sonography, and hyperintense at T2 with malignant enhancement at MR. Immunohistochemical assessment is mandatory for the final diagnosis. The radiologist can suggest this particular subtype of tumour.

Abstract
626 Background: The determination of ER and PR has a considerable importance when evaluating the prognosis and the response to treatment in breast cancer (BC). Assessment of HER2 status is also a standard for the management of BC. Hormone receptors (HR), HER2, and increasingly, genomic profiles distinguish at least four major classes of BC: HER2+; HER2-HR+, which can be divided into two classes, favorable and unfavorable; and basal-like that express neither HER2 nor HR. In the clinical practice is possible to divided BC according to ER, PR and HER2: ER-PR-HER2+, ER-PR-HER2-, ER+PR+HER2-, ER+RP+HER2+; and less frequently ER+PR-HER2-, ER+PR-HER2+, ER-PR+HER2+ and ER-PR+HER2-. In the neoadjuvant setting the pathological complete response (pCR) to primary chemotherapy (PC) is associated to negativity for ER and PR receptors, and in patients (pts) with HER2 + BC, the addition of trastuzumab to PC increasing the rate of pCR. The aims of this study were to determine the pCR of PC with anthracyclines (A) and taxanes (T) in pts with LABC grouped according to ER, PR and HER2 status. Methods: Pts with LABC treated with PC including A and T were grouped according to ER, PR and HER2 status, and the pCR rate were analyzed using the chi-squared test and correlations with a p value of ≤0,05 were considered statistically significant. Results: A total of 103 pts were treated. There were 14.6% of ER-PR-HER2+ BC, 23.3% ER-PR-HER2-, 35.0%ER+PR+HER2-, 8.7% ER+PR+HER2+, 11.7% ER+PR-HER2-, 2.9% ER+PR-HER2+, 1.9% ER-PR+HER2+, and 1.9% ER-PR+HER2-. For the analysis of pCR only 100 pts were included. There were18 pts who achieved a pCR. Of these pts, 9/18 (50.0%) were RE-RP-HER2-, 5/18 (27.8%) ER-PR-HER2+, 3/18 (16.7%) ER+PR+HER2+, and 1/18 (5.6%) ER+PR+HER2- (p≤0.01). The table 1 show the pCR rate for each subgroup of BC. Conclusions: In patients with LABC to group BC according to ER, PR and HER2 status can help to predict pCR to PC. [Table: see text] No significant financial relationships to disclose.

Abstract
PURPOSE To assess the feasibility of the Sentinel lymph node biopsy (SLNB) technique in cutaneous non-melanoma malignancies. MATERIALS AND METHODS Nine patients were retrospectively evaluated performing a scintigraphy with 99mTc-nanocolloid. On the day of the surgery, an initial dynamic study and static images were obtained. The first drainage station visualized was considered the sentinel node (SLN). The SLN position was marked on the skin and after a correct localization in the surgical field with a gamma probe the SLN was obtained. Patients of this study have been followed up for 8 to 48 months. RESULTS Lymphoscintigraphy detected the sentinel node in 88,8 % of our studies (the SLN was not observed in a patient with a Merkel's tumour on the back). The SLN was identified intraoperatively in those patients with positive imaging. Those cases without scintigraphic demonstrated migration were also not found intraoperatively. Histopathological analysis of the SLN showed non metastatic disease and none patient developed metastases or local recurrence in the monitoring period. CONCLUSIONS Sentinel node biopsy can be applied to certain cutaneous non-melanoma malignancies. In patients with unclear drainage and to avoid unnecessary lymphadenectomy, the technique offers clear advantages. In our study the SLN analysis was related to the clinical progress. A large number of patients should be examined to truly assess the benefit of this technique in this kind of malignancies and to determinate when the technique must be performed.

Abstract
We present an unusual case of hepatocellular carcinoma presenting as massive portal vein thrombosis with progression to the intrahepatic bile ducts without demonstrable primary hepatic tumor. Ultrasound, magnetic resonance, and percutaneous transhepatic cholangiography findings are described. The histologic diagnosis was achieved by means of percutaneous forceps biopsy of the endobiliary mass.
