Abstract
After the study of circulating tumor cells in blood through liquid biopsy (LB), this technique has evolved to encompass the analysis of multiple materials originating from the tumor, such as nucleic acids, extracellular vesicles, tumor-educated platelets, and other metabolites. Additionally, research has extended to include the examination of samples other than blood or plasma, such as saliva, gastric juice, urine, or stool. LB techniques are diverse, intricate, and variable. They must be highly sensitive, and pre-analytical, patient, and tumor-related factors significantly influence the detection threshold, diagnostic method selection, and potential results. Consequently, the implementation of LB in clinical practice still faces several challenges. The potential applications of LB range from early cancer detection to guiding targeted therapy or immunotherapy in both early and advanced cancer cases, monitoring treatment response, early identification of relapses, or assessing patient risk. On the other hand, gastric cancer (GC) is a disease often diagnosed at advanced stages. Despite recent advances in molecular understanding, the currently available treatment options have not substantially improved the prognosis for many of these patients. The application of LB in GC could be highly valuable as a non-invasive method for early diagnosis and for enhancing the management and outcomes of these patients. In this comprehensive review, from a pathologist's perspective, we provide an overview of the main options available in LB, delve into the fundamental principles of the most studied techniques, explore the potential utility of LB application in the context of GC, and address the obstacles that need to be overcome in the future to make this innovative technique a game-changer in cancer diagnosis and treatment within clinical practice.

Abstract
Gastric cancer (GC) is a heterogeneous disease, often diagnosed at advanced stages, with a 5-year survival rate of approximately 20%. Despite notable technological advancements in cancer research over the past decades, their impact on GC management and outcomes has been limited. Numerous molecular alterations have been identified in GC, leading to various molecular classifications, such as those developed by The Cancer Genome Atlas (TCGA) and the Asian Cancer Research Group (ACRG). Other authors have proposed alternative perspectives, including immune, proteomic, or epigenetic-based classifications. However, molecular stratification has not yet transitioned into clinical practice for GC, and little attention has been paid to alternative molecular classifications. In this review, we explore diverse molecular classifications in GC from a practical point of view, emphasizing their relationships with clinicopathological factors, prognosis, and therapeutic approaches. We have focused on classifications beyond those of TCGA and the ACRG, which have been less extensively reviewed previously. Additionally, we discuss the challenges that must be overcome to ensure their impact on patient treatment and prognosis. This review aims to serve as a practical framework to understand the molecular landscape of GC, facilitate the development of consensus molecular categories, and guide the design of innovative molecular studies in the field.

Abstract
OBJECTIVES Several alternative lymph node staging systems have recently been described for gastric cancer. The log odds of positive lymph nodes (LODDS) system may be superior to the pN stage (American Joint Committee on Cancer) and lymph node ratio systems in predicting outcomes for patients with gastric cancers, as indicated by some researchers. Most studies, however, have been conducted in Asian countries, and conflicting results have been reported by other investigators. METHODS We conducted a retrospective study of all 377 cases of gastric cancer resected at a tertiary hospital in Spain between 2000 and 2019. Clinicopathologic features were collected, LODDS were calculated and categorized into 5 groups (S1-S5), and statistical analysis was performed. RESULTS The cases included (n = 315) were classified as S1 (25.6%), S2 (18.4%), S3 (21.3%), S4 (20.3%), and S5 (14.4%). The LODDS classification was significantly associated with tumor size, Laurén subtype, presence of signet ring cells, tumor grade, perineural infiltration, lymphovascular invasion, growth pattern, pT, tumor recurrence, and death. Kaplan-Meier analysis based on the LODDS classification demonstrated improved patient stratification compared with the pN stage for both overall survival (OS) and disease-free survival (DFS). Area under the curve values for recurrence and death were superior for the LODDS classification, and this classification was independently related to OS and DFS. In addition, the LODDS classification successfully divided patients without lymph node metastases (pN0) into subgroups with distinct prognoses. CONCLUSIONS For our cohort, the LODDS system showed better prognostic performance than pN stage; it was an independent predictor of OS and DFS, and it provided valuable prognostic information in cases without lymph node metastases. Its prognostic accuracy, however, decreased in cases with fewer than 16 lymph nodes resected.

Abstract
INTRODUCTION Lymph node (LN) involvement is one of the most critical prognostic factors in resected gastric cancer (GC). Some analyses, mainly conducted in Asian populations, have found that patients with a higher number of total lymph nodes (NTLN) and/or negative lymph nodes (NNLN) have a better prognosis, although other authors have failed to confirm these results. MATERIALS AND METHODS Retrospective study including all patients with GC resected in a tertiary hospital in Spain between 2001 and 2019 (n = 315). Clinicopathological features were collected and patients were categorized according to the NTLN and the NNLN. Statistical analyses were performed. RESULTS Mean NNLN was 17. The NNLN was significantly related to multiple clinicopathological variables, including recurrence and tumor-related death. The classification based on the NNLN (N1: ≥16, N2: 8-15, N3: ≤7) effectively stratified the entire cohort into three distinct prognostic groups and maintained its prognostic value within both the pN0 and pN+ patient subsets. Furthermore, it was an independent prognostic indicator for both overall and disease-free survival. Conversely, the mean NTLN was 21.9. Patients with ≤16 LN retrieved exhibited distinct clinicopathological features compared to those with >16 LN, but no significant differences were observed in terms of recurrence or disease-associated death. The application of alternative cut-off points for NTLN (10, 20, 25, 30, and 40) showed no prognostic significance. CONCLUSIONS In Spanish patients with resected GC the NNLN hold prognostic significance, while the NTLN does not appear to be prognostically significant. Incorporating the NNLN into GC staging may enhance the accuracy of the TNM system.

Abstract
Objectives The hyalinizing trabecular tumor (HTT) is a rare benign neoplasm of the thyroid gland. This neoplasm has overlapping cytological features with Papillary Thyroid Carcinoma, Medullary Carcinoma and Follicular Neoplasm with Nuclear Features of Papillary Carcinoma. This can lead to misdiagnosis of malignancy in fine needle aspiration (FNA) cytology specimens with unnecessary total thyroidectomy. The aim of this study is to determine if there are some cytological features that could help us to suspect HTT on FNA specimens and avoid radical surgery. Material and Methods With this purpose we have collected 6 cases diagnosed of HTT in Hospital Clínico San Carlos of Madrid (Spain) in the last 10 years and reviewed the cytological specimens. Result We conclude that the presence of hyaline material in FNA specimens of HTT is a constant feature being a diagnostic clue. We must be cautious not to confuse it with dense colloid or amyloid material, the latter seen in Medullary Carcinoma. Papillary architecture and fibrovascular cores are not present in a HTT. Special stains as ki-67, calcitonin and Congo Red staining could help us in achieving the correct diagnosis. Conclusion We feel the cytopathologists must be aware of the distinguishing features of this lesion, mainly the typical hyaline material to achieve a proper diagnosis and be able to reduce unnecessary aggressive management of these patients.

Abstract
The impact of age on various aspects of gastric cancer (GC) remains controversial. Clarifying this issue can improve our understanding of the disease, refine risk stratification models, and aid in personalized therapeutic approaches. This study aimed to evaluate the influence of age at diagnosis on the clinicopathological features, prognosis, and management of a specific cohort of Spanish patients with resected GC. The study encompassed 315 patients treated at a single tertiary hospital in Spain, divided into two age-based subgroups: ≤65 years and >65 years. The mean and median ages at diagnosis were 72 and 76 years. Most tumors were diagnosed at pT3 stage (49.2%), and 59.6% of patients had lymph node metastases. 21.3% of cases were diagnosed with GC at age ≤ 65 years. Younger patients showed a significantly higher prevalence of flat, diffuse, high-grade tumors, signet-ring cells, perineural infiltration, D2 lymphadenectomies, and adjuvant therapy. They also exhibited a higher rate of recurrences, but had a significantly longer follow-up. Kaplan-Meier curves indicated no significant prognostic differences based on age. Finally, age did not independently predict overall survival or disease-free survival. Our results suggest that younger patients may require more aggressive treatment due to adverse clinicopathologic features, but the lack of prognostic differences among age groups in our cohort indicates the need for further investigation into the complex interplay between age, clinicopathologic factors, and long-term outcomes in GC.

Abstract
BACKGROUND In the molecular era, the Laurén system is still a cost-effective and widely implemented classification for gastric cancer (GC) and it has been recently associated with clinical, histological and molecular features of these tumors. Despite recent advances in the understanding of the molecular biology of GC, there is a need to develop new prognostic tools for patient stratification in clinical practice. Thus, the identification of easily available prognostic factors in patients with intestinal and diffuse-type tumors can significantly improve risk assessment and patient stratification in GC.
AIM To identify clinicopathological differences, risk factors, and to develop cost-effective prognostic scores for patients with intestinal and diffuse-type GC.
METHODS Retrospective study of all patients undergoing surgery for GC at a tertiary referral center from 2001 to 2019. 286 cases met inclusion criteria (intestinal: 190, diffuse: 96). Clinical data and gross findings were collected. All specimens were reviewed by two independent pathologists and a detailed protocol for histologic evaluation was followed. Five tissue microarrays (TMAs) were constructed and sections of the TMA block were immunostained for HERCEPTEST, MSH2, MSH6, MLH1 and PMS2. Statistical analyses were performed and prognostic scores were developed based on hazard ratios.
RESULTS Intestinal and diffuse-type GC showed different epidemiological, clinicopathological and prognostic features. Diffuse tumors were significantly associated with younger age, less symptomatology, flat morphology, deeper invasion, perineural infiltration, advanced stage at diagnosis, administration of adjuvant therapy and poorer prognosis. Intestinal lesions were fungoid or polypoid, showed necrosis, desmoplasia, microsatellite instability and HERCEPTEST positivity and were diagnosed at earlier stages. Tumor depth, desmoplasia, macroscopic type and lymph node involvement were independently related to the Laurén subtype. Furthermore, intestinal and diffuse GC were associated with different risk factors for progression and death. Vascular invasion, perineural infiltration and growth pattern were important prognostic factors in intestinal-type GC. On the contrary, tumor size and necrosis were significant prognosticators in diffuse-type GC. Our recurrence and cancer-specific death scores for patients with intestinal and diffuse-type GC showed an excellent patient stratification into three (diffuse GC) or four (intestinal) prognostic groups.
CONCLUSION Our findings support that Laurén subtypes represent different clinicopathological and biological entities. The development of specific prognostic scores is a useful and cost-effective strategy to improve risk assessment in GC.

Abstract
OBJECTIVES The TNM classification is the main tool for lymph node (LN) staging in gastric cancer (GC). However, alternative LN staging systems have been proposed, and the role of features other than the number of metastatic LNs is being investigated. Our aim is to discuss the main challenges of LN assessment in GC. METHODS Comprehensive review of the literature on alternative LN staging systems, examined LNs, sentinel LN (SLN) biopsy, LN micrometastases (LNMIs), extracapsular extension (ECE), and tumor deposits (TDs) in GC. RESULTS Many controversies exist regarding LN assessment in GC. The TNM classification shows excellent prognostic performance, but alternative prognostic methods such as the LN ratio or log odds of positive LNs have demonstrated to be better than the TNM system in terms of prognostic accuracy. The value of SLN biopsy and LNMIs in GC is still unclear, and several challenges concerning their clinical impact and pathologic analysis must be overcome before their introduction in clinical practice. Most authors have identified ECE and TDs as independent prognostic factors for survival in GC. CONCLUSIONS Further studies should be performed to evaluate the impact of these features on the TNM classification and patient outcomes, as well as to standardize alternative LN staging systems.

Abstract
Most studies on the clinicopathological impact of Borrmann classification for gastric cancer (GC) have been performed in Asian patients with type IV tumors, and immunohistochemical features of Borrmann types have scarcely been analyzed. We assessed the clinicopathological, molecular features and prognostic value of Borrmann types in all patients with advanced GC resected in a Western institution (n = 260). We observed a significant relationship between Borrmann types and age, systemic symptoms, tumor size, Laurén subtype, presence of signet-ring cells, infiltrative growth, high grade, tumor necrosis, HERCEPTEST positivity, microsatellite instability (MSI) and molecular subtypes. Polypoid GC showed systemic symptoms, intestinal-type histology, low grade, expansive growth and HERCEPTEST positivity. Fungating GC occurred in symptomatic older patients. It presented intestinal-type histology, infiltrative growth and necrosis. Ulcerated GC showed smaller size, intestinal-type histology, high grade and infiltrative growth. Most polypoid and ulcerated tumors were stable-p53-not overexpressed or microsatellite unstable. Flat lesions were high-grade diffuse tumors with no MSI, and occurred in younger and less symptomatic patients. No association was found between Borrmann classification and prognosis. According to our results, Borrmann types may represent distinct clinicopathological and biological entities. Further research should be conducted to confirm the role of Borrmann classification in the stratification of patients with advanced GC.

Abstract
Gastric cancer (GC) is an aggressive tumor, which is usually diagnosed at an advanced stage and shows high mortality rates. Several GC classifications have been published, based on features such as tumor location, endoscopic features or microscopic architecture. However, TNM stage remains the mainstay of GC management and treatment. In the last years, technical advances have allowed us to investigate the biological heterogeneity of GC and develop new molecular classifications. This knowledge may enhance current classifications, and has the potential to refine GC management and aid in the identification of new molecular targets. In this literature review we have summarized the main findings in epidemiology, screening, classification systems and treatment of GC, focusing on the molecular alterations and new molecular classifications published in the last years.

Abstract
INTRODUCTION The TNM staging system is the main prognostic tool for GC, but the number of metastatic lymph nodes (LN) can be affected by surgical, pathological, tumor or host factors. Several authors have shown that lymph node ratio (LNR) may be superior to TNM staging in GC. However, cut-off values vary between studies and LNR assessment is not standardized. MATERIAL AND METHODS Retrospective study of all GC resected in a western tertiary center (N = 377). Clinical features were collected and pathological features were assessed by two independent pathologists. Eight LNR classifications were selected and applied to our patients. Statistical analyses were performed. RESULTS 315 patients were included. Most tumors were T3 (49.2%) N+ (59.3%). During follow-up, 36.7% of patients progressed and 27.4% died due to tumor. All LNR classifications were significantly associated with clinicopathological features such as Laurén subtype, lymphovascular invasion, perineural infiltration, T stage, tumor progression or death. All LNR classifications were independent prognostic factors for OS and DFS, and ROC analyses calculated similar AUC values for all staging systems. Kaplan-Meier curves showed that Pedrazzani, Wang, Liu and Huang classifications stratified patients better into three (Pedrazzani) or four categories. These classifications tended to downstage TNM N2 and N3 tumors. In cases with less than 16 LNs resected, Pedrazzani and Wang classifications showed the best prognostic performance. CONCLUSIONS Pedrazzani, Wang, Liu and Huang classifications showed good prognostic performance in western GC patients. Larger studies in other cohorts are needed to identify the most consistent LNR classification for GC.

Abstract
Gastric cancer (GC) is the fifth most common cancer and the third cause of cancer-related deaths worldwide. In western countries, more than half of GC patients are diagnosed at advanced stages and 5-year survival rates range between 20-30%. The only curative treatment is surgery, and despite recent advances in oncological therapies, GC prognosis is still poor. The main prognostic tool for patient categorization and treatment selection is the TNM classification, but its limitations are being increasingly recognized. Early recurrences may occur in early-stage disease, and patients at the same stage show heterogeneous outcomes. Thus, there is a need to improve GC stratification and to identify new prognostic factors, which may allow us to select drug-susceptible populations, refine patient grouping for clinical trials and discover new therapeutic targets. Molecular classifications have been developed, but they have not been translated to the clinical practice. On the other hand, histological assessment is cheap and widely available, and it is still a mainstay in the era of molecular medicine. Furthermore, histological features are acquiring new roles as reflectors of the genotype-phenotype correlation, and their potential impact on patient management is currently being analyzed. The aim of this literature review is to provide a modern overview of the histological assessment of GC. In this study, we discuss recent topics on the histological diagnosis of GC, focusing on the current role of Laurén classification and the potential value of new histological features in GC, such as inflammatory infiltration and tumor budding.

Abstract
INTRODUCTION Gastric cancer (GC) shows high recurrence and mortality rates. The AJCC TNM staging system is the best prognostic predictor, but lymph node assessment is a major source of controversy. Recent studies have found that lymph node ratio (LNR) may overcome TNM limitations. Our aim is to develop a simplified tumor-LNR (T-LNR) classification for predicting prognosis of resected GC. METHODS Retrospective study of all GC resected in a tertiary center in Spain (N = 377). Clinicopathological features were assessed, LNR was classified into N0:0%, N1:1-25%, N2:>25%, and a T-LNR classification was developed. Statistical analyses were performed. RESULTS 317 patients were finally included. Most patients were male (54.6%) and mean age was 72 years. Tumors were intestinal (61%), diffuse (30.8%) or mixed (8.1%). During follow-up, 36.7% and 27.4% of patients progressed and died, respectively. T-LNR classification divided patients into five prognostic categories (S1-S5). Most cases were S1-S4 (26.2%, 19.9%, 22.6% and 23.6%, respectively). 7.6% of tumors were S5. T-LNR classification was significantly associated with tumor size, depth, macroscopical type, Laurén subtype, signet ring cells, histologic grade, lymphovascular invasion, perineural infiltration, infiltrative growth, patient progression and death. Kaplan-Meier curves for OS showed an excellent patient stratification with evenly spaced curves. As for DFS, T-LNR classification also showed good discriminatory ability with non-overlapping curves. T-LNR classification was independently related to both OS and DFS. CONCLUSIONS T-LNR classifications can successfully predict prognosis of GC patients. Larger studies in other geographic regions should be performed to refine this classification and to validate its prognostic relevance.

Abstract
BACKGROUND Factors other than pTNM stage have been associated with gastric cancer (GC) prognosis, and several alternative prognostic scores have been constructed. Our aims are to identify prognostic factors in western GC patients and to build clinicopathological prognostic models for overall survival (OS) and disease-free survival (DFS). METHODS A Retrospective study of 204 cases of GC resected during the years 2000 to 2014 was conducted in our hospital. Clinicopathological features were assessed, univariate and multivariate analysis were performed and prognostic scores were constructed. RESULTS Most patients were diagnosed at pTNM stages II and III (36.9% and 48.1%, respectively). According to Laurén classification, tumors were intestinal (55.8%), diffuse (35.2%) and mixed (9%). During follow-up, 43.5% of patients had tumor recurrence, and 28.6% died due to tumor. Univariate analysis showed that patient age, Laurén subtype, signet-ring cell morphology, pTNM stage, tumor grade, perineural invasion, growth pattern, intratumoral inflammation, adjuvant therapy, and desmoplasia were significantly related to tumor progression or death. Multivariate analysis showed that Laurén subtype, pT stage, and lymph node ratio (LNR) were significantly and independently associated with GC recurrence. Laurén subtype and LNR were significantly related to patient survival. Prognostic scores for tumor progression and death were developed and patients were classified into four prognostic groups which showed good prognostic performance. CONCLUSION A prognostic model comprising histological features such as Laurén subtype can be easily applied in clinical practice, and provides more prognostic information than pTNM stage alone. These models can further stratify resected GC patients and have the potential to aid in the individualization of patient management.

Abstract
Immunophenotypical features from tumors can be variable and, sometimes, confusing. We herein report a 61 year old woman with two foci of papillary thyroid microcarcinoma who developed a bone lesion four months after total thyroidectomy/central lymphadenectomy (mpT1aN0), with an immunohistochemical pattern suggestive of a pulmonary rather than a thyroid origin (CK7, napsin-A and TTF1 positive; and negative thyroglobulin). Further biomarkers (HBME-1 and PAX8) were performed in order to confirm primary tumor, leading to conclusion of a bone metastasis from thyroid papillary carcinoma. We believe it is always advisable to perform more than one biomarker as part of a panel to get a more reliable diagnosis.

Abstract
INTRODUCTION Gastric cancer (GC) is a multifactorial disease. Several prognostic scores have been proposed for refining the prognostic information provided by the TNM classification. Our aim is to validate and compare the prognostic performance of different clinicopathological scores in a western cohort of patients (Marubini, Haraguchi and Kologlu scores). MATERIAL AND METHODS Retrospective study of all cases of GC resected in a western tertiary center (N = 377). Clinicopathological features were collected, scores were applied and statistical analyses were performed. RESULTS 315 cases were finally included. According to Marubini, Haraguchi and Kologlu scores, patients were stage I (18.5%, 13.3% and 49%), II (29.3%, 47.2% and 29.5%) and III (52.2%, 39.5% and 21.5%, respectively). All classifications were significantly associated with lymphovascular invasion, perineural infiltration, lymph node involvement, patient progression and death due to GC. All scores showed good patient stratification by Kaplan-Meier analyses, but OS and DFS curves depending on Haraguchi score were less evenly spaced. Kologlu classification showed prognostic superiority over Haraguchi and Marubini classifications by ROC analysis. AUC values for OS and DFS were 0.654 and 0.647 (Marubini), 0.626 and 0.618 (Haraguchi) and 0.724 and 0.709 (Kologlu). Kologlu and Marubini classifications were independent factors for both OS and DFS, but Haraguchi classification was independently associated only with DFS. CONCLUSIONS Clinicopathological scores can be easily validated and are cost-effective. Kologlu score is the most thorough classification, and it showed the best prognostic performance for both DFS and OS in our study. More studies are needed to validate its value in other populations.

Abstract
The distinction between reactive mesothelium and carcinoma in serous effusions can be very difficult. Immunocytochemistry (ICC) is the most widely used tool to improve the diagnostic accuracy of body fluid cytology, with several ICC markers being proposed. Ber-EP4 antibody has shown high sensitivity and specificity rates for diagnosing metastatic carcinoma. In our department, we have detected Ber-EP4 positivity in mesothelium in some cytological specimens. We reviewed all articles on Ber-EP4 staining in effusion cytology, summarized current findings and analyzed the staining pattern of all cases expressing Ber-EP4. Some cases showing Ber-EP4 positivity in mesothelium have been reported, most of which showed only weak Ber-EP4 staining or staining of less than 50% of mesothelial cells. However, some cases may show strong positivity both in cytological and histological specimens. Clinicians and pathologists should be aware of this source of misdiagnosis, and ICC results in mesothelium should be always interpreted cautiously and correlated with clinical tests, other ICC markers and patient's previous history.

Abstract
Reactive lymphoid hyperplasia of the liver is an unusual benign lesion of unknown pathogenesis. The largest reported series to date includes only 7 cases. Reactive lymphoid hyperplasia can be radiologically confused with malignant tumors such as hepatocellular carcinoma or metastases. Histological differential diagnosis should be chiefly made with lymphomas, Castleman disease and primary biliary cirrhosis. We report the clinicopathological findings in a 54-year-old woman with an incidental hepatic lesion when she consulted for hematuria. After histological, immunohistochemical and molecular studies, the diagnosis of reactive lymphoid hyperplasia was made.

Abstract
We herein report a rather peculiar case of acute liver injury. A 78-year-old woman developed asthenia and weakness. Her previous medical history was irrelevant, except for having received etoricoxib 60 mg/24 h for osteoarthritis 1 month before. Liver biochemistry indicated hepatic failure; all tests for viral, bacterial, or parasitic infections were negative, as were the autoimmunity tests. As the patient's status gradually declined, a transjugular hepatic biopsy was obtained and confirmed hepatocyte necrosis with severe inflammation and presence of numerous eosinophils. Suspecting a potential toxic cause of the disorder, the patient was requestioned and admitted curcuma consumption for a long time. She was asked to discontinue it and her status gradually improved, with normalization of all the analytical parameters. On the long-term follow-up, she remains well. We consider that this case of acute liver injury can be explained with the combination of the acute toxic effect of a drug, etoricoxib, and the herbal remedy curcuma. This case is illustrative of the risk of interactions between drugs and natural remedies, and to the best of our knowledge, it is the first case of severe hepatotoxicity related to etoricoxib, probably potentiated by long-term curcumin intake. Besides, it illustrates the fact that patients do not generally consider natural remedies as potential source of toxicity, and this can lead to a delay in diagnosis.

Abstract
INTRODUCTION Excisional or core needle biopsy is considered the gold standard for diagnosing soft tissue lesions (STL). However, the role of fine-needle aspiration cytology (FNAC) in STL remains controversial. MATERIALS AND METHODS We have reviewed 234 FNAC of STL diagnosed in our institution with the aim of analyzing the reliability of FNAC in STL. Cytological diagnoses were classified into groups and correlated with histological diagnoses. We have also reviewed the literature and compared our results with those previously reported. RESULTS The majority of patients were male (53.4%) and mean age was 61 years. Lesions were mainly located in the head and neck region. Inadequate material was obtained in 22.6% of cases and most lesions were inflammatory lesions or benign soft tissue tumors. Carcinoma and benign soft tissue tumor were the most frequent cytological diagnoses. Biopsy was performed in 36.1% of cases, and carcinoma was detected in 33.3% of inflammatory FNACs. General and specific concordances were 65.9% and 47.1%. Diagnostic sensitivity, specificity, negative and positive predictive values were 71.4%, 100%, 85.7% and 93.8%, respectively. CONCLUSIONS FNAC of STL is a valuable tool for diagnosing benign epithelial cysts, carcinomas, hematolymphoid neoplasms and benign soft tissue tumors. Inflammatory smears may be associated with false-negative cases. The availability of a multidisciplinary team, clinical and imaging features, ROSE and immunohistochemical and molecular techniques is required for improving the role of FNAC of STL.

Abstract
Histiocytic and dendritic cell neoplasms (HDN) are rare and their biology, prognosis, treatment and terminology are still under discussion. They are composed of macrophage and dendritic-derived cells and show a wide range of clinical, morphological and prognostic features. Clinicopathological correlation and a broad immunohistochemical panel are required to establish a correct diagnosis. After the detection of BRAF mutations in Langerhans cell histiocytosis, the potential role of other molecular alterations is being studied. We have reviewed the literature published in the last 10 years to provide an overview of NHD, with particular emphasis their molecular features.

Abstract
INTRODUCTION Neuroendocrine tumors (NETs) occur more often in lungs, gastrointestinal tract, or pancreas. Data about terminology and grading of NETs in rare locations are scarce and variable, and they have been reported mainly as case reports. MATERIALS AND METHODS We here describe our experience with NETs in unusual locations. We have reviewed all NETs diagnosed in our institution and summarized their clinicopathological features. We have also reviewed the literature and discussed the main characteristics of NETs in each site. RESULTS Two hundred and forty-three primary NETs were diagnosed. About 55.2% of patients were men and the mean age was 62 years. About 90.7% of NETs were located in lungs, gastrointestinal tract, or pancreas, and 50.8% of them were low-grade tumors. We identified 13 NETs in rare locations: breast, ovary, endometrium, vulva, uterine cervix, extrahepatic biliary tract, kidney, sinonasal tract, and thymus. Three additional tumors were diagnosed by the senior author in other institution. Patients were asymptomatic or presented with nonspecific symptoms. All NETs were treated with surgery and 31% of patients received adjuvant therapy. There were 10 Grade 3 (62.5%), 2 Grade 2 (12.5%), and 4 Grade 1 (25%) tumors. Mean follow-up was 72 months. About 60% of G3 tumors recurred or progressed. G2 tumors were located in breast, and both patients are stable. About 50% of G1 tumors recurred or progressed (both renal NETs). CONCLUSIONS NETs in rare locations are heterogeneous, and their behavior does not seem to correlate absolutely with tumor grade. More studies are needed to clarify the role of proliferation rate in these tumors.

Abstract
Adenomyoepitheliomas of the breast are infrequent tumors with a variable histological appearance, and they can mimic several epithelial, myoepithelial and biphasic lesions of the breast. We have reviewed four cases of adenomyoepithelioma of the breast diagnosed between 2005 and 2015 in our institution (Hospital Clínico San Carlos). Mean age was 57years. All lesions were solid irregular masses located in the upper quadrants (3 of them in the right breast and one in the left), with an average size of 13mm. Microscopically 2 of them were tubular and the remaining 2 were lobulated subtypes. Hyaline, myxoid and cystic areas, peripheral pseudoinfiltration and satellite nodules were occasionally seen. Myoepithelial cells were fusiform and immunohistochemically they were actin, calponin, p63, S100 and CD10 positive and CKAE1-AE3 negative, with variable CK23BE12 and CK5/6 staining. In all cases lumpectomy was curative, no recurrences or malignant degeneration were observed.

Abstract
Heterotopic neural tissue (HNT) has been identified in many sites. In our literature review, we have found only two cases of HNT located in the retroperitoneum. As far as we know, cytological features of HNT have not been described. We here report a case of retroperitoneal HNT diagnosed by fine-needle aspiration (FNA) cytology and subsequent resection. Our patient was a male infant born at 26 weeks' gestation. A retroperitoneal solid-cystic lesion measuring 3.8 cm was identified by abdominal ultrasound. FNA was performed and cytology showed highly cellular smears with single cells and masses of fibrillary material. Cells were small with rounded irregular nuclei and variable cytoplasm. Multinucleated cells, cells with neuronal morphology, calcifications, and hemosiderophages could also be seen. The lesion was excised and histology showed fibrillary areas, glial cells, neurons, and ependymal cells. Synaptophysin, GFAP, and EMA were expressed in distinct areas and cell types. No recurrences were observed.

Abstract
Neuroendocrine pancreatic tumors (PanNETs) are graded on the basis of their proliferative activity. Cytological samples are commonly the only samples available, but the determination of Ki-67 in cytology and its reliability as a measure of tumor mitotic activity is not well settled. We have retrospectively reviewed all the cases of FNA under EUS control of PanNETs in a 10-year period (2006-2016) in the Hospital Clínico San Carlos (Madrid). We identified 10 PanNET cases with histological correlation. Median age was 49.4 years and the patients were mainly women. PanNETs were located more frequently in the tail of the pancreas, with a median size of 33.8 mm. None of our cases was a grade 3 tumor. The seven grade 1 tumors confirmed in histology had consistent Ki-67 in cytology. In three cases (30 %), there were discrepancies between the Ki-67 index measured in cytology and histology, and the differences ranged from 2 to 15 %; all these cases were grade 2 tumors in histology and were graded as grade 1 tumors in FNA material. Our results are consistent with previous studies which showed understaging when tumor grade was assessed in cytological samples, mainly in G2 tumors. Previous literature has shown that Ki-67 assessment in EUS-FNA samples is a useful tool to rule out G3 tumors, but can be problematic for distinguishing G1 and G2 tumors.

Abstract
OBJECTIVES To review our institutional experience and to analyze the clinical decisions made after a cytological diagnosis of atypia of undetermined significance or follicular lesion of undetermined significance (AUS/FLUS). STUDY DESIGN This is a retrospective review of all thyroid fine-needle aspiration (FNA) cytologies performed in the Hospital Clínico San Carlos (Madrid) between 2010 and 2014. RESULTS One hundred thirty thyroid FNA were categorized as AUS/FLUS (5%). One hundred six (81.5%) patients were women, and the mean age was 59 years. In 61 patients a repeated FNA was performed (46%). Fifty-five nodules were treated surgically (42.3%), with a histopathological diagnosis of nodular hyperplasia in 36 cases (65%), adenoma in 11 (20%), and carcinoma in 8 (14.5%). In the group of nonsurgical patients (n = 75), a repeated FNA was performed in 43 (57.3%) cases. We found no statistically significant association between sex or age and clinical management (p = 0.13 and p = 0.31, respectively). CONCLUSIONS Clinical management after an AUS/FLUS FNA diagnosis is erratic and does not match standardized management protocols. The AUS/FLUS classification has not led to new diagnostic tests in a relevant percentage of patients. The implementation of consensual institutional strategies could lead to better management of these cases.

Abstract
Leiomyoma of the seminal vesicles is an extremely rare type of benign tumor of the genitourinary system and can cause lower urinary tract symptoms. Despite their low incidence, these tumors can be identified with transrectal ultrasound of the seminal vesicles during prostate examination. The removal of these tumors is facilitated by a laparoscopic approach.

Abstract
INTRODUCTION AND OBJECTIVES Radical surgery is the standard treatment for localised gastrointestinal stromal tumours (GIST). A series of primary GIST, their treatment and pre-established risk of recurrence after their follow-up is evaluated. MATERIAL AND METHODS A retrospective, descriptive and multicentre study was conducted on primary, non-metastatic GIST operated on between June 2007 and December 2008. The variables of greater relevance were analysed, including, location, size, mitotic index, and NHI and AFIP recurrence prognostic criteria, and their correlation with the disease-free survival (DFS) of the patients. RESULTS The series included 141 patients with a mean age of 65 years. The most frequent GIST location was in the stomach (70.8%) and small intestine (22.9%), and with a mean tumour size of 6.7 cm (0.5-35 cm). The surgery was R0 in 97.2% of cases (laparoscopic approach, 21.5%). The distribution according to NHI/Flescher criteria was, high (31.95%), and intermediate (26.4%), and according to AFIP/Miettinen criteria it was, high (22.9%) and intermediate (12.5%). After a mean follow-up of 20.3 months, there was a 7.1% (10 cases) recurrence, with only 2 cases belonging to the group with a «low risk» using the NHI and AFIP prognostic criteria. The DFS at one year was 95.5% and 91.5% at 2 years. CONCLUSIONS The series showed a high DFS and a good correlation with both the Flescher and the Miettinen criteria. However, the risk of recurrence varied according to the AFIP criteria (intermediate/high, 58.3%), or the AFIP criteria (intermediate/high, 35.4%) which included the tumour location. For this reason, we consider these latter criteria as the most adequate for assessing the prognostic risk of GIST recurrence.

Abstract
Metastastic tumours involving the epididymis are rare and most often found in patients with disseminated disease. It is even more unusual when the metastasis of the epididymis is the first sign of tumour recurrence. We report a case of an asymptomatic recurrent colon carcinoma presenting as metastasis in the epididymis. Although metastatic cancer presenting as an intra-scrotal mass is extremely rare, it should be considered as a possibility in patients who present with a mass involving the testicle or epididymis.

Abstract
UNLABELLED SUMMARY-BACKGROUND: The present study investigates the hypothesis that cells from ill patients and from healthy subjects may have different reactivity under metabolic stimulation as a consequence of an disease-induced metabolic adaptation. METHODS Granulocytes either from healthy subjects or from type II-Non Insulin Dependent Diabetes Mellitus (NIDDM) patients were compared in their capacities to generate Reactive Oxygen Species (ROS). The ROS generation was comparatively determined in a chemiluminescence assay, luminol-dependent, after cell incubation in the presence of either cyclic AMP - elevating agents or Interleukin 10. In some experiments the cells were pretreated with H89 compound (a PKA inhibitor) or with diphenylene iodonium (DPI), a NADPH-oxidase inhibitor. RESULTS Our results showed an increased ROS generation in granulocytes from diabetic patients in absence of cyclic AMP-elevating agents or IL-10. In the presence of cyclic AMP-elevating agents was observed an inverse metabolic response in granulocytes from diabetic patients in comparison to cells from healthy subjects. The granulocytes were pre-incubated in the presence of cyclic AMP-elevating agents--amminophylline (AMF) or dibutyryl cyclic AMP (dbcAMP)--or interleukin 10 (IL-10). The AMF, dbcAMP and IL-10 inhibited ROS production by granulocytes from healthy subjects. By contrast, AMF and dbcAMP activated cells from diabetic patients while IL-10 had no effect. The inhibition of ROS induced by AMF, dbcAMP or IL-10 was promptly abolished by the pretreatment of the cells with either PKA H89 inhibitor or NADPH-oxidase inhibitor (DPI) in granulocytes from healthy subjects. In relation to the granulocytes from type 2 diabetics patients, the activation of ROS generation mediated by AMF and dbcAMP was fully abolished by NADPH-oxidase DPI-inhibitor, but not by PKA H89 inhibitor. CONCLUSIONS Our present results reinforce the hypothesis that cells from ill patients (type II diabetic) when compared to cells from healthy subjects have different reactivity under metabolic stimulation. ROS production by human granulocytes was modulated by cyclic AMP elevating agents and IL-10. The inhibition of the ROS production in cells from healthy subjects was PKA-dependent while the activation in granulocytes from patients was PKA-independent. This inverse metabolic response, in cells from patients, suggests the use of an alternative metabolic pathway PKA-independent, possible cAMP/Epac/PKB-dependent. The correlation between activation of ROS production in granulocytes from diabetic patients and pathogenesis of diabetes can be suggested, however, further and extensive studies are needed for demonstrating this suggestion.

Abstract
BACKGROUND The present study was designed to investigate the hypothesis that cells from ill patients and from healthy subjects may have different reactivities under metabolic stimulation. METHODS The study was performed with granulocytes from non-diabetic subjects and from type II -Non Insulin Dependent Diabetes mellitus (NIDDM) patients. The nitric oxide (NO) generation was comparatively determined by the nitrite concentration (micromolar of nitrite) after cell incubation in the presence of cyclic nucleotide-elevating agents. RESULTS Our results showed an inverse reactivity for granulocytes from diabetic patients when compared to non-diabetic subjects. Granulocytes were incubated in the presence of drugs that elevate the intracellular level of cyclic AMP aminophylline (AMF), dibutyryl cyclic AMP (dbcAMP)], cyclic GMP [8.Br. cyclic GMP(8.Br.cGMP) or levamisole (LEV)]. The cyclic AMP-elevating agents (AMF and d bcAMP) inhibited NO production by granulocytes from non-diabetic subjects and activated cells from diabetic patients. By contrast, cyclic GMP-elevating agents (8.Br.cGMP and LEV) activated cells from non-diabetic subjects and inhibited granulocytes from diabetic patients. The activation of NO generation by cyclic nucleotides was blocked by pretreatment of granulocytes with L-NAME. CONCLUSION The authors describe for the first time that both cyclic AMP and cyclic GMP were able to modulate nitric oxide production in human granulocytes and that cell reactivity in ill patients (diabetic) showed altered and inverse response in comparison to granulocytes from healthy subjects. This inverse reactivity possibly reflects a disease-induced adapted metabolic response. The consequences of this altered metabolic response on host defense and inflammation may be speculated, but further experiments are needed to confirm this hypothesis.
