Abstract
Objectives To investigate the relationship between high-molecular-weight cytokeratin (34βE12) and clinicopathological parameters (including HER-2, Ki67 and steroid receptors) in breast cancer to determine its usefulness as a prognostic marker. Methods In this retrospective study, the expression level 34βE12 was assessed in surgically resected breast cancer specimens by immunohistochemical staining. Data were correlated with the patients’ clinicopathological parameters. Results Of the 348 breast cancer tissue samples, 232 (67%) showed positive expression of 34βE12. There were statistically significant differences between the positive and negative 34βE12 expression groups in tumour size, lymph node involvement, oestrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER2) status. There were no differences between groups in age, tumour grade, or Ki67 status. In addition, patients who were positive for 34βE12 had significantly extended overall survival. In multivariate analysis, the expression level of 34βE12 was found to be a significant independent prognostic factor. Conclusion These results suggest that positive 34βE12 expression is associated with a favourable outcome in breast cancer and so may be a useful prognostic factor. Further studies are required to confirm these results.

Abstract
Papillary renal neoplasm with reverse polarity is a form of recently described tumor. These tumors are defined by GATA3 positivity, negative vimentin staining, and the presence of both papillary structures and a layer of eosinophilic cells with apical nuclei and a granular cytoplasm. In the present report, we review 7 cases of papillary renal neoplasm with reverse polarity that were GATA3+ and vimentin-, consistent with past reports. In all 7 of these cases, we found that these tumors were additionally positive for 34βE12. All 7 of these tumors were categorized as stage pT1. On histological examination, these tumors exhibited branching papillae with apical nuclei. All 7 of these patients were alive on most recent follow-up, with 6 being disease free and one having developed prostate cancer. Together, this overview of 7 additional cases of papillary renal neoplasm with reverse polarity offers further insight into this rare and poorly understood disease.

Abstract
BACKGROUND Prostate carcinoma (PC) is the second most diagnosed cancer in men population worldwide. The small amount of the tissue in prostate needle biopsy is often sufficient for the correct interpretation. Novel antibodies, as ERG, could add to the diagnostic value of IHC study in analysing difficult core biopsies. AIM The aim of the present study was to establish a diagnostic use of ERG in a work-up of prostate needle biopsies containing minute PC, individually and in combination with AMACR/34βE12. MATERIALS AND METHODS From total number of 1710 consecutive prostate needle biopsies based on HE stain 114 biopsies containing minute PC. Selected biopsies were incubated with anti-ERG, AMACR and 34βE12 antibodies using immunohistochemical technique. RESULTS Among 98 selected biopsies, 57 showed positive and 41 negative ERG staining. AMACR staining was positively expressed in 86 of the cases and completely absent in remaining 12. In 9 of the AMACR-negative cases the final diagnosis was establish by manifestation of ERG expression in the tumour foci. 95 of the biopsies demonstrated lack of 34βE12 expression and only 3 cases showed weak patchy staining. Among these cases 2 were ERG-positive. CONCLUSION ERG antibody could be especially helpful in the cases with controversial expression of AMACR and 34βE12.

Abstract
Clear cell papillary renal cell carcinoma (CCPRCC) is a recently recognised neoplasm with a broad spectrum of morphological characteristics, thus representing a challenging differential diagnosis, especially with the low malignant potential multicystic renal cell neoplasms and clear cell renal cell carcinoma. We selected 14 cases of CCPRCC with a wide spectrum of morphological features diagnosed on morphology and CK7 immunoreactivity and analysed them using a panel of immunohistochemical markers, focusing on 34βE12 and related CKs 1,5,10 and 14 and several molecular analyses such as fluorescence in situ hybridisation (FISH), array comparative genomic hybridisation (aCGH), VHL methylation, VHL and TCEB1 sequencing and multiplex ligation-dependent probe amplification (MLPA). Twelve of 13 (92%) CCPRCC tumours were positive for 34βE12. One tumour without 3p alteration by FISH revealed VHL mutation and 3p deletion at aCGH; thus, it was re-classified as clear cell RCC. We concluded that: (1) immunohistochemical expression of CK7 is necessary for diagnostic purposes, but may not be sufficient to identify CCPRCC, while 34βE12, in part due to the presence of CK14 antigen expression, can be extremely useful for the recognition of this tumour; and (2) further molecular analysis of chromosome 3p should be considered to support of CCPRCC diagnosis, when FISH analysis does not evidence the common loss of chromosome 3p.

Abstract
Seborrheic keratosis with basal clear cells (SKBCC) is an extremely rare histopathological variant of seborrheic keratosis that has histological similarities to melanoma in situ. We herein report two cases of SKBCC and provide the first description of the dermoscopic features of this condition, in addition to the histopathological findings. Both of the two lesions showed typical histological architectures of seborrheic keratosis with rows or focal clusters of monomorphic clear cells with abundant pale cytoplasm and small round nucleus in the basal layer. Immunohistochemical examination revealed that most clear cells were positive for high molecular weight cytokeratin (34βE12) in a peripheral pattern but were negative tor Melan-A. Dermoscopy revealed typical features of ordinary seborrheic keratosis, while unfortunately did not reflect the presence of basal clear cells.

Abstract
Prostatic lesions on routine staining sometimes cause diagnostic dilemma especially in premalignant lesions like atypical adenomatous hyperplasia and prostatic intraepithelial neoplasia. Benign small acinar lesions also may be difficult to differentiate from small acinar adenocarcinoma. An important differentiating point is the loss of basal cell layer in adenocarcinoma and its presence in benign lesions. Basal cell markers (e.g. 34βE12 cytokeratin) & proliferative markers (e.g. AgNOR and PCNA) can help in this regard. Total 60 cases of different prostatic lesions studied. After history taking, clinical examination, radiological & other investigations were done. Routine H&E staining, immunohistochemical staining against 34βE12 cytokeratin & proliferative markers (AgNOR & PCNA) was performed. Statistically significant differences found in expression of 34βE12 cytokeratin and proliferative markers between benign, premalignant and malignant prostatic lesions. Basal cell markers and proliferative markers are important parameters to distinguish between different benign, premalignant and malignant prostatic lesions.
