    ABSTRACT: Infiltrating angiolipoma and osteolipoma of the hand are rare. A 40-year-old man presented with slowly enlarging swelling of his right hand for two and half years without functional deficit but it became painful with slight limitation of movement for the past few months. Plain radiograph showed a large soft tissue swelling with specks of calcifications. Ultrasonography and magnetic resonance imaging revealed an infiltrative mass in the right palm deep to the flexor tendons. As biopsy suggested infiltrative angiolipoma of skeletal muscle, debulking of the tumor was performed. The tumor showed coexistence of all four mesenchymal elements, fat, blood vessel, smooth muscle and bone in various combinations in the form of angiolipomatous, osteolipomatous, ossified intramuscular hemangiomatous, myolipomatous and angiomyolipomatous patterns throughout the entire tumor. Small meningothelial-like whorls of spindle cells were focally seen, some showed intramembranous ossification forming small woven bony spicules in their centers. There were no atypical cells or lipoblasts. Staining for CDK4, MDM2, p16, HMB45 and Melan A was negative. The diagnosis was "infiltrating hybrid mesenchymal tumor of skeletal muscle showing lipomatous, hemangiomatous, leiomyomatous and osseous features". The fairly even admixture of the various components supports the neoplastic participation of each individual element. Hybrid mesenchymal tumor most probably originates from multipotent neoplastic cells showing multidirectional differentiation. Copyright © 2015 Elsevier GmbH. All rights reserved.

    ABSTRACT: Inflammatory myofibroblastic tumor is an uncommon tumor regarded as “intermediate malignancy”. We present the clinical, pathological and molecular features of a mesenteric inflammatory myofibroblastic tumor in a 9-month-old male infant. The patient was referred to Anna Meyer Children Hospital of Florence, Italy, for an asymptomatic abdominal mass measuring about 7 cm. The lesion was radically excised, and the postoperative course was uneventful. Histologically, the tumor was composed of spindle cells immunopositive for vimentin and desmin admixed with an inflammatory infiltrate. Rearrangement of ALK gene was demonstrated by FISH and immunohistochemistry (cytoplasmic, perinuclear and punctate immunocoloration). The peculiar punctate ALK immunocoloration suggested a possible unusual ALK gene rearrangement involving the CLTC gene.

    ABSTRACT: The aim of the present study was to determine the chemokine RANTES (regulated on activation, normal T-cell expressed, and secreted) levels in plasma and atherosclerotic plaques and to assess their diagnostic efficacy in the evaluation of vulnerable plaques. The rabbit models of vulnerable atherosclerotic plaque (VAP) were established by high fat diet and pharmaceutical triggering. The serum RANTES levels of VAP group (91.97 ± 8.51 ng/ml) were significantly higher than that of AS (atherosclerosis) group (50.03 ± 2.92 ng/ml). Consistently, the mRNA and protein of RANTES in vulnerable atherosclerotic plaques were also obviously up-regulated compared to AS group (P < 0.01). Moreover, corrected plaque area and vulnerability index of VAP group proved to be significantly higher than AS group. The correlation coefficient between RANTES and plaque vulnerability indicated that RANTES, especially plaque RANTES, was positively correlated with VAP. In addition, increased expression of Nuclear factor kappa B p65 (NF-κB p65) was observed in VAP group compared to AS group (P < 0.05), which partly accounted for the increased RANTES levels. In conclusion, positive associations between RANTES and plaque vulnerability suggest that higher RANTES levels may be associated with atherosclerosis and high-risk plaques. Our study highlights the utility of both serum and plaque RANTES levels as indicators of plaque vulnerability in the field of preventive cardiology.

    ABSTRACT: Temsirolimus acts as a mammalian target of rapamycin (mTOR)-dependent autophagic inhibitor. In order to clarify its effects and mechanisms on human salivary adenoid cystic carcinoma (ACC), we examined that whether temsirolimus induced autophagy as the mTOR inhibitor in ACC, both in vitro and in vivo. In this study, MTT assay showed that the inhibition effect of temsirolimus assumed an obvious dose-response relationship on ACC-M cells, and the 50% inhibitory concentration (IC50) approached 20 μmol/l; numerous autophagosomes were observed by the transmission electron microscopy (TEM) in temsirolimus treatment groups; what's more, expression of LC3 and Beclin1 was significantly up-regulated by temsirolimus. More importantly, the xenograft model provided further evidence of temsirolimus-induced autophagy in vivo, by inhibiting mTOR activation as well as up-regulation the expression of Beclin1. These results suggest that temsirolimus could act as an mTOR inhibitor to induce autophagy in adenoid cystic carcinoma both in vitro and in vivo.

    ABSTRACT: Background and Aims TRAF2- and NCK-interacting kinase (TNIK) is a member of the germinal center kinase family and a transcription factor 4 (TCF4) interactor that is recruited to promoters of Wnt target genes via phosphorylation of the TCF/β-catenin complex. The aim of this study was to evaluate the TNIK, the active form of TNIK (p-TNIK), and β-catenin expression in hepatocellular carcinoma (HCC) and identify the prognostic significance of p-TNIK. Methods: We assessed the expression status of TNIK, p-TNIK, and β-catenin by using immunohistochemical analysis of 302 HCCs in 8 tissue microarray blocks, and we evaluated their clinicopathologic features and survival rates based on their p-TNIK expression. Results: Of 302 HCCs, 92.7% stained positive for TNIK in the cytoplasm. Nuclear expression of p-TNIK was identified in 7.9% HCCs. Aberrant cytoplasmic expression of β-catenin was identified in 77.2% and nuclear expression in 3.3%. p-TNIK nuclear staining was positively correlated to β-catenin nuclear expression (P = 0.036). Cytoplasmic and nuclear expression of p-TNIK was more frequently observed in high Edmonson–Steiner (ES) nuclear grade groups (P = 0.030). Nuclear p-TNIK expression was also associated with pathological M1 stage (pM1 stage) patients (P < 0.0001). Aberrant cytoplasmic expression of β-catenin was more frequently identified in bigger tumors (P = 0.014). Univariate (DFS, P = 0.049; OS, 0.037) and multivariate analysis (DFS, P = 0.006; OS, P = 0.003) confirmed the independent prognostic significance of nuclear p-TNIK expression. Conclusion: This is the first time that nuclear p-TNIK expression was studied in HCC, and p-TNIK nuclear expression was associated with poor prognosis and is a candidate prognostic marker for HCC.

    ABSTRACT: Introduction There is now increased understanding that invasive cribriform carcinoma is a relatively aggressive disease. In some recent publications, the recommendation is that all cribriform patterns be classified as Gleason pattern (GP) 4 rather than GP 3. Materials and Methods We assessed the cribriform foci (CF) associated with the more definitive patterns 3, 4, and 5 elsewhere on the 185 radical prostatectomy specimens and evaluated the association of the cribriform pattern with extraprostatic extension, surgical margin. Results CF were more frequently observed in cases with definitive patterns 4 and 5 than in cases with pattern 3 (all cases with pattern 5 exhibited CF). Cases with Gleason score 3 + 3 and CF were more frequently associated with extraprostatic extension, and a positive surgical margin. Conclusions Our results demonstrate that diagnosing all cribriform patterns as at least GP 4 would significantly affect further therapeutic options and prognosis. However, as many of these modifications are empirical and supported by only a few studies, long-term follow-up studies with clinical endpoints are necessary to validate these recommendations.

    ABSTRACT: Cyclooxygenase-2 (COX-2), overexpressed in many types of human cancer, may be valuable marker for human melanoma. However, there are discrepancies between expression levels detected by different groups. Majority of the studies was carried out using standard paraffin sections. Tissue microarrays (TMAs) might enable analysis of COX-2 expression in numerous lesions. Our study assesses to what extent reprocessing of tissue samples used for preparing TMAs may influence reproducibility of data obtained for standard sections. The study included TMAs and standard histopathologic sections. COX-2 was detected by immunohistochemistry with two primary antibodies targeting different epitopes. COX-2 expression levels detected with both antibodies in standard sections were similar as in our previous study. Surprisingly, results obtained in TMAs were significantly different. While one of the antibodies yielded for TMAs results similar to standard sections, COX-2 expression levels found with the second antibody were very low and expression patterns strikingly different from those observed for standard sections and for both TMAs studied with the first antibody. Good performance of the antibodies found in standard sections of human skin and melanocytic lesions does not guarantee similar results in TMAs. The finding discloses new aspect of immunohistochemical assays involving TMAs.

    ABSTRACT: The aim of the present study was to explore ERG immunoreactivity in a series of sarcomas, GIST and malignant rhabdoid tumor (MRT), considering the not fully elucidated specificity and sensitivity of this antibody. Paraffin-embedded tissue microarrays from those tumors were stained with anti-ERG against the C-terminus [(EPR3864(2)] and N-terminus (Clone 9FY). EPR3864(2) was positive in almost all angiosarcomas, and MRT.GIST were positive in a large proportion of cases (38.4%), and more than half the synovial sarcomas (52.7%) revealed EPR3864(2) staining. Several chondrosarcomas, osteosarcomas, rhabdomyosarcoma and Ewing's sarcoma family of tumors (ESFT) presented EPR3864(2) expression in a lower number of cases. 9FY was positive in most of the angiosarcomas; however, only sporadic ESFT and synovial sarcoma were positive and the other tumors tested were negative. Fourteen ESFT with EWSR1/Fli-1 gene fusion presented positive nuclear staining for EPR3864(2). Similarly, 5 ESFT with EWSR1/Fli-1 gene fusion presented positive staining for 9FY. We must stress that the difference between the present and previous studies may be due to the source of the anti-ERG employed, anti-ERG against C or N-terminus, protein cross-reactivity and dilution. In conclusion, specificity for ERG staining in sarcomas should be considered with caution apnd the immunoexpression is undoubtedly influenced by clone and antibody selection.

    ABSTRACT: Background and Aim To explore the expression and role of Activating Transcription Factor 3 in Human hepatocellular carcinoma. Methods Immunohistochemistry, Western blot assay and Real-time PCR were used to evaluate Activating Transcription Factor 3 protein and gene level in HCC clinical samples. Results Activating Transcription Factor 3 expression is lowest in HCC, and the protein level is lower in patients with capsule invasion, while no association with other main clinical pathological features. Conclusions Low expression of ATF3 may function as a tumor suppressor during human hepatocellular oncogenesis and targeting ATF3 pathway might be beneficial for anti-HCC therapy.

    ABSTRACT: Papillary thyroid carcinoma (PTC) is the most common type among thyroid cancers. The diagnosis of PTC may be challenging when follicular variant (FVPTC) of this disease is present due to the resemblance of nuclear properties of the classical type (CVPTC). However, making use of ancillary molecular markers in the diagnosis of PTC may help. In our study, we aimed to evaluate the SEPT7 protein expression in PTC. A total of 55 paraffin block tissue samples comprising encapsulated FVPTC (FVPTC(e), n = 25), and CVPTC (n = 15), and benign hyperfunctioning thyroid nodules (HypN, n = 15) were used in this study. Nuclear, cytoplasmic, and overall (total) SEPT7 protein expression levels were determined by using immunohistochemistry. Nuclear, cytoplasmic, and overall SEPT7 expressions (p = 0.02, p = 0.001, p = 0.002, respectively) were significantly lower in FVPTC(e) tissues when compared to HypN. In CVPTC group, nuclear expression was significantly lower (p = 0.004) while overall and cytoplasmic expressions were not changed (p > 0.05). In HypN group, highest nuclear (mean = 2.73), cytoplasmic (mean = 2.86), and overall (mean = 2.86) expression scores were detected. Significantly lower SEPT7 expression in all expressional categories in FVPTC(e) group may be a sign of different molecular signature in this type of tissue.

    ABSTRACT: Purpose Breast cancer is a heterogeneous disease. Immunohistochemistry has given rise to triple-negative carcinoma (TNC). Concomitantly, biological origins of neoplasia and its heterogeneity has been strongly debated in cancer stem cells (CSC) theme. This study investigates the prevalence of basal (BCC) and penta-negative carcinomas (5NC) in TNC and establishes associations with CSC (CD44CD24). Materials and Methods 94 TNC were tested for CK5/6, HER1, CD44 and CD24, evaluated by a simple immunohistochemistry score and correlated with clinicopathological and survival data. Results BCC had higher tumor grades than 5NC (p = 0.004). CD44 negativity (p = 0.007) and CD44-CD24+ phenotype (p = 0.013) were associated with less vascular invasion amongst TNC. CD44 expression was associated with BCC (p = 0.007). CD44-CD24-/low phenotype was associated with 5NC. None of the variables were associated with clinical outcome. Conclusion BCC and 5NC are closely related tumor subtypes. CD44-CD24-/low phenotype was associated with 5NC and CD44-CD24+ phenotype was associated with vascular invasion. These results require histogenetic confirmation in larger studies.

    ABSTRACT: The aim of the present study was to evaluate the expressions of beclin 1 and bcl-2 in prostate cancer (PC) and high grade prostatic intraepithelial neoplasia (HGPIN), and to investigate their relationship with clinicopathological parameters. The study included 30 benign prostatic hyperplasia (BPH), 40 HGPIN and 106 primary PC cases. The expressions of beclin 1 and bcl-2 were assessed semiquantitatively based on both the percentage and intensity of positive staining cells. Beclin 1 was positive in 27 (90%) BPH, 37 (92.5%) HGPIN, and 90 (84.9%) PC cases (p>0.05). Bcl-2 immunostaining was detected in 99 (93.4%) PC, 37 (92.5%) HGPIN, and 9 (30%) BPH cases (p<0.0001). Regarding expression scores, beclin 1 was significantly lower in PC cases than in the HGPIN and BPH groups (p<0.0001), and it was also negatively correlated with Gleason score (p=0.004, r=-0.274). Bcl-2 expression score was significantly higher in PC than in the other groups (p<0.0001), and also positively correlated with Gleason score (p<0.0001, r=0.425). Furthermore, a negative correlation was found between bcl-2 and beclin 1 expression scores in PC cases (p=0.006, r=-0.265). Our results suggest an association between bcl-2 and beclin 1 expressions in malignant transformation of prostate tissue and also in regulating PC cell differentiation, progression and the agressiveness of PC.

    ABSTRACT: The aim of this study was to investigate the expression rates of CD133 and CD90 in cirrhosis-dysplastic nodule-HCC (Crh-DN-HCC) sequence related to the etiologic background. Thirty-five HCC, 8 small cell dysplasia (SCD), and 63 cases of cirrhosis having different etiologies were collected. Immunohistochemical expressions of CD133 and CD90 were evaluated. CD133 positivity was higher in HCC cases with chronic hepatitis B and CD90 with chronic hepatitis C. The highest staining rate was seen in poorly differentiated HCC cases. Only one SCD case and almost half of the cirrhotic cases which were stained for CD133 were associated with hepatitis B; none was stained for CD90. Increased CD133 expression indicated a significantly shorter overall survival rate. No significant relationship was detected between the expression rates of CD133 or CD90 and other parameters. In this study, which investigates the immunohistochemical expression profiles of CD133 and CD90 through Crh-DN-HCC sequence, the highest staining rate was detected in HCC. It is rational to try to elucidate the earliest events in hepatocarcinogenesis by studying SCD. It is important to be aware of this issue in daily practice, which will provide a deeper insight into the understanding of the effects of CSCs in the progression and management of HCC.

    ABSTRACT: Sirenomelia, a developmental defect involving the caudal region of the body, is associated with several internal visceral anomalies. We report a detailed spectrum of anomalies in an autopsy study of four fetuses with sirenomelia (gestational ages–20, 21, 22.4, and 22.5 weeks). Three of the fetuses had single umbilical artery, with genitourinary and gastrointestinal anomalies. Central nervous system anomalies were evident in two of the fetuses, with alobar holoprosencephaly in one and lumbar meningomyelocele in another. The most common gastrointestinal anomaly was blind ended gut (imperforate anus), while esophageal atresia and omphalocele were noted in one case each. Renal hypoplasia was seen in two fetuses, agenesis in one and cystic renal dysplasia was noted in one case. Literature regarding pathogenesis of this condition is briefly discussed.
