Abstract
INTRODUCTION Insulin-like growth factor-II messenger RNA-binding protein-3 (IMP3) over-expression is a predictor of tumor recurrence and metastases in some types of human melanoma. Our objective was to evaluate the immunohistochemical expression of IMP3 and other molecules related to tumor prognosis in melanoma-xeno-tumors undergoing treatment. We test the effect of radiotherapy (RT) and mesenchymal stromal cells (MSCs) treatment, analyzing the tumorigenic and metastatsizing capacity in a mice melanoma xenograft model. MATERIALS AND METHODS We inoculated A375 and G361 human melanoma cell lines into NOD/SCID gamma mice (n = 64). We established a control group, a group treated with MSCs, a group treated with MSCs plus RT, and a group treated with RT. We assessed the immunohistochemical expression of IMP3, E-cadherin, N-cadherin, PARP1, HIF-1α, and the proliferation marker Ki-67. Additionally, we performed a retrospective study including 114 histological samples of patients diagnosed with malignant cutaneous superficial spreading melanoma (n = 104) and nodular melanoma (n = 10) with at least 5 years of follow-up. RESULTS Most morphological and immunohistochemical features show statistically significant differences between the 2 cell lines. The A375 cell line induced the formation of metastases, while the G361 cell line provoked tumor formation but not metastases. All three treatments reduced the cell proliferation evaluated by the Ki-67 nuclear antigen (p = 0.000, one-way ANOVA test) and reduced the number of metastases (p = 0.004, one-way ANOVA test). In addition, the tumor volumes reduced in comparison with the control groups, 31.74% for RT + MSCs in the A357 tumor cell line, and 89.84% RT + MSCs in the G361 tumor cell line. We also found that IMP3 expression is associated with greater tumor aggressiveness and was significantly correlated with cell proliferation (measured by the expression of Ki-67), the number of metastases, and reduced expression of adhesion molecules. CONCLUSIONS The combined treatment of RT and MSCs on xenografted melanomas reduces tumor size, metastases frequency, and the epithelial to mesenchymal transition/PARP1 metastatic phenotype. This treatment also reduces the expression of molecules related to cellular proliferation (Ki-67), molecules that facilitate the metastatic process (E-cadherin), and molecules related with prognosis (IMP3).

Abstract
BACKGROUND The incidence of glomerular disease recurrence in kidney transplant patients varies according to type of glomerulopathy; therefore, it is important to know the primary chronic kidney disease etiology. C3 glomerulopathy (C3G) is characterized by deposits of C3 in immunofluorescence and its pathogeny is based on the dysregulation of the alternative complement pathway. C3G has a high recurrence rate and, given its low prevalence, only case series have been published. A higher rate of recurrence and a more aggressive course have been described in association with monoclonal gammopathy (MG). CASE REPORT We describe the case of a 78-year-old man with chronic kidney disease of unknown etiology (no significant proteinuria) and monoclonal IgGl gammopathy with low risk of progression, who received a kidney transplant, presenting accelerated deterioration of kidney function. Histopathology showed predominant C3 deposits in immunofluorescence, compatible with C3 glomerulonephritis (C3GN). He was treated with eculizumab during 4 weeks while the study was completed. The response to treatment was not favorable and the patient remained in the dialysis program. CONCLUSIONS Further studies are needed to explain the pathogenic mechanisms of complement alternative pathway dysregulation mediated by monoclonal component in patients with C3GN and MG. Patients older than 50 years who are on a waiting list for kidney transplantation should have an MG detection study. The information provided to patients with MG on a waiting list for kidney transplantation should include not only the possibility of hematologic progression but also the recurrence/de novo appearance of associated kidney pathology.

Abstract
Background: An antibody panel is needed to definitively differentiate between adenocarcinoma (AC) and squamous cell carcinoma (SCC) in order to meet more stringent requirements for the histologic classification of lung cancers. Staining of desmosomal plaque-related proteins may be useful in the diagnosis of lung SCC.Materials and methods: We compared the usefulness of six conventional (CK5/6, p40, p63, CK7, TTF1, and Napsin A) and three novel (PKP1, KRT15, and DSG3) markers to distinguish between lung SCC and AC in 85 small biopsy specimens (41 ACs and 44 SCCs). Correlations were examined between expression of the markers and patients' histologic and clinical data.Results: The specificity for SCC of membrane staining for PKP1, KRT15, and DSG3 was 97.4%, 94.6%, and 100%, respectively, and it was 100% when the markers were used together and in combination with the conventional markers (AUCs of 0.7619 for Panel 1 SCC, 0.7375 for Panel 2 SCC, 0.8552 for Panel 1 AC, and 0.8088 for Panel 2 AC). In a stepwise multivariate logistic regression model, the combination of CK5/6, p63, and PKP1 in membrane was the optimal panel to differentiate between SCC and AC, with a percentage correct classification of 96.2% overall (94.6% of ACs and 97.6% of SCCs). PKP1 and DSG3 are related to the prognosis.Conclusions: PKP1, KRT15, and DSG3 are highly specific for SCC, but they were more useful to differentiate between SCC and AC when used together and in combination with conventional markers. PKP1 and DSG3 expressions may have prognostic value.

Abstract
PURPOSE To examine differences in morphology and in immunophenotype subsets between chronic periodontitis (CP) and peri-implantitis (P-I) lesions and to test the diagnostic agreement (CP vs P-I) among three independent observers, based on histopathological features. MATERIALS AND METHODS This observational cross-sectional study included 15 gingival biopsies of CP lesions and 15 biopsies of P-I lesions for double-blinded examination by three independent pathologists. Inflammatory infiltrate intensity was assessed semiquantitatively on a 4-point scale, determining the percentage of lymphocytes, plasma cells, monocytes/macrophages, and granulocytes and the presence/absence of bacterial colonies. Immunohistochemical analyses were performed to verify the inflammatory infiltrate subset data (CD45, CD38, CD68 and myeloperoxidase [MPO]-positive), and number of vessels. Kappa statistic was used to evaluate the degree of diagnostic concordance among examiners. RESULTS Inflammatory infiltrate was significantly more severe in P-I cases (P = 0.01), which showed a significantly higher percentage of plasma cells (P = 0.004) than in CP cases. Immunohistochemically, the percentage of leukocyte subsets was generally lower in CP (CD38: 32.05%; CD68: 6.45% and MPO: 8.62%) than in P-I (CD38: 61.13%; CD68: 9.09% and MPO: 7.47%) (CD38 P = 0.001, P = 0.955 and P = 0.463, for remaining subsets, respectively; Mann-Whitney U-test). The inter-observer diagnostic agreement was poor or slight (kappa = -0.18 to 0.13). CONCLUSIONS Despite the significantly more severe general inflammatory infiltrate and plasma cells in P-I cases, it proved difficult to detect reliable differential morphological features based on histopathological images of these CP and P-I soft-tissue samples, obtaining low inter-observer and intra-observer diagnostic agreement. Conflict of interest statement: This investigation was partially supported by Research Groups #CTS-138 and #CTS-583 (Junta de Andalucía, Spain). No conflict of interest.

Abstract
UNLABELLED The aim of this study was to characterize the morphology and immunophenotype of ganglion cysts (GCs) and explore their histogenetic origin. MATERIAL AND METHODS A cross-sectional morphological and immunohistochemical study of 354 GCs used the following antibody panel: vimentin, specific actin, β-actin, smooth-muscle actin, smoothelin, h-caldesmon, β-catenin, desmin, calponin, podoplanin, keratins 5/6, E-cadherin, cyclooxygenase 2 (COX-2), lysozyme, CD10, CD31, CD33, CD34, CD68, Ki-67, and PCNA. Double-blind semi-quantitative analyses were conducted to evaluate the immunopositivity on a 4-point scale. Samples from 10 synovial membranes and 10 scapholunate ligaments were compared. GCs showed a hyalinized wall with mesenchymal spindle cells and were intensely positive for vimentin, actins, h-caldesmon, calponin in all cases and for podoplanin in 53% of cases, suggesting features of early muscle differentiation, without ruling out a myofibroblastic origin. Focal cavity lining of non-synovial flat or raised cells (CD34/CD31/CD10/E-cadherin-negative and podoplanin-positive in 34% of cases) was detected in 93% of cases, showing differential expression with synovial membrane and scapholunate ligament cells. Nuclear positivity for proliferative markers was observed in GC wall cells (258.1±255; 1019.3±316 positive cells/mm², Ki-67 and PCNA, respectively) but positivity for these markers was significantly lower (p⟨0.001 Mann Whitney U-test) in scapholunate ligament samples. CONCLUSION In this first immunohistochemical study of GCs, focal cellular lining of the cavity was observed in almost all cases, and the immunophenotype was identical to that of GC wall cells. These cells are immunohistochemically different from synoviocytes and scapholunate ligament cells and show characteristics of myofibroblasts or mesenchymal cells undergoing early muscle differentiation.

Abstract
AIM To analyze and compare the expression of MTNR1A receptor in normal and pathological major and minor salivary glands. MATERIALS AND METHODS Twenty samples of major and minor salivary glands and 10 with Warthin's tumor were studied. Expression of the MTNR1A receptor (goat polyclonal antibody raised against a peptide mapping at the N-terminus of MEL-1A R of human origin) was analyzed. RESULTS The excretory ducts of major salivary glands demonstrated intense intracytoplasmic positivity but scant cytoplasmic membrane positivity for MTNR1A. The studied Warthin's tumors showed intense cytoplasmic positivity for MT1 receptor in all cylindrical epithelial cells lining spaces and a less intense positivity in basal cells. The lymphoid component accompanying the tumor was negative for MT1 receptor. CONCLUSION Intense intracytoplasmic positivity for the MTNR1A receptor in the excretory ducts of human major and minor salivary glands and Warthin's tumor was found. The intense expression of MTNR1A receptors observed in this study in the excretory ducts of major and minor salivary glands may be related to salivary regulation.

Abstract
AIMS To study liver lesions in morbidly obese patients who underwent liver biopsy at the time of bariatric surgery to define histological lesions, especially inflammatory infiltrate, diagnostic categories and the possible influence of gender in this respect. METHODS AND RESULTS 110 biopsies (36 males-M- and 76 females -F-) were evaluated and categorised, according to the NAS (NAFLD -non alcoholic fatty liver disease- Activity Score) system and other criteria, as non-NAFLD (15.5%, F predominance), non-alcoholic steatohepatitis (NASH) (16.5%, M predominance), non-alcoholic hepatosteatosis (NAHS) (21%, F predominance) and, the most numerous group, NASH-borderline (NASH-BORD) (47%), with three subgroups, characterised by centrozonal lesions, portal area preferential involvement or affecting both areas. The predominant form of hepatocytesteatosis was mixed with a multivesicular component that was present in most cases with fibroinflammatory portal involvement. Nuclear glycogenosomes were found in greater number of biopsies in patients in the third and sixth decades. Portal inflammation was present in a large number of cases (M predominance); the application of immunohistochemical techniques (myeloperoxidase and CD68 antibodies) to evaluate lobular inflammation revealed "surgical hepatitis" in one third of the cases, and the presence of microgranulomas (CD68+) (M predominance), which were more abundant with increasing lesion severity. CONCLUSIONS Portal inflammation and multivesicular hepatocytesteatosis are highly prevalent in morbidly obese patients. This study identifies a new subtype of NASH-BORD characterized by centrizonal and porto-periportal area involvement and the existence of liver biopsies without steatosis. CD68+ microgranulomas constitute an unequivocal marker of lobular inflammation in surgical biopsies and of lesion severity, which is gender-related.

Abstract
Myositis ossificans circumscripta is a form of heterotopic ossification that is benign in nature associated to a trauma, but may appear clinically and radiologically as a malignant neoplasm. We describe a rare case of calcifying of myositis ossificans not associated to trauma in a 35-year-old woman with a mass in her upper third and external of right thigh. We discuss some of the difficulties of diagnosis and histological evolution of the lesion.
