Abstract
INTRODUCTION Synchronous visceral malignancy is rare especially for esophagogastric junction adenocarcinoma combined with malignancy in the pancreas. So far only 7 cases of combined partial pancreatoduodenectomy and esophagectomy for synchronous malignancy have been described in the literature and none for combined total pancreatectomy and esophagectomy. PRESENTATION OF CASE We report the case of a 67-year-old male patient, who underwent multi-modality treatment including two-stage total pancreatoduodenectomy and subsequent Ivor-Lewis esophagectomy for synchronous adenocarcinoma of the distal esophagus and pancreatic multilocal metastases of a renal cell carcinoma after nephrectomy 17 years ago. Pathology revealed R0 resections for both malignancies and there were no postoperative complications. A 12 months follow-up showed no signs of recurrence and a good quality of life. CONCLUSION Curative-intent, combined oncological two-stage open total pancreatoduodenectomy and esophagectomy with several days interval is safe and feasible in selected cases when performed by an experienced interdisciplinary team in a high-volume surgical center.

Abstract
Deciduosis is defined as the presence of decidual tissue in an ectopic location. It is caused by progesterone-mediated metaplasia of mesenchymal cells. We describe a case of a non-pregnant patient with extensive peritoneal spread. As in this report, this entity might mimic oncological conditions.
Ectopic decidual reaction (or deciduosis) can be rarely seen in the peritoneum and most of the cases in the literature are associated with pregnancy. It is more commonly found in the ovaries, uterus and cervix. Although its pathophysiology is not totally understood, it is accepted that peritoneal deciduosis develops as a result of the progesterone induced metaplasia of subserosal stromal cells during pregnancy. It is important to distinguish this entity from oncologic conditions, namely metastatic carcinoma and mesothelioma. We report an unusual case of a 40 year-old non pregnant patient that presented with imaging findings suggestive of peritoneal carcinomatosis.

Abstract
Metastatic castration-resistant prostate cancer (mCRPC) is considered as the final stage of the disease with limited therapeutic options to date. In this article, we review recent histopathologic and molecular pathologic findings that may expand our understanding of the disease and may lay, or have already laid the groundwork for the development of novel and individualized therapies. These include the detection of pathogenic mutations in the DNA repair genes BRCA1/2, androgen receptor splice variant 7 (AR-V7), deletion of the tumor suppressor gene PTEN, and evidence of neuroendocrine prostate cancer (t-NEPC) arising under antiandrogenic therapy. The theoretical and diagnostic basis behind the increasing relevance of pathology for therapeutic guidance in this stage of disease are presented.

Abstract
Chronic hypoxia is associated with a variety of physiological conditions such as rheumatoid arthritis, ischemia/reperfusion injury, stroke, diabetic vasculopathy, epilepsy and cancer. At the molecular level, hypoxia manifests its effects via activation of HIF-dependent transcription. On the other hand, an important transcription factor p53, which controls a myriad of biological functions, is rendered transcriptionally inactive under hypoxic conditions. p53 and HIF-1α are known to share a mysterious relationship and play an ambiguous role in the regulation of hypoxia-induced cellular changes. Here we demonstrate a novel pathway where HIF-1α transcriptionally upregulates both WT and MT p53 by binding to five response elements in p53 promoter. In hypoxic cells, this HIF-1α-induced p53 is transcriptionally inefficient but is abundantly available for protein-protein interactions. Further, both WT and MT p53 proteins bind and chaperone HIF-1α to stabilize its binding at its downstream DNA response elements. This p53-induced chaperoning of HIF-1α increases synthesis of HIF-regulated genes and thus the efficiency of hypoxia-induced molecular changes. This basic biology finding has important implications not only in the design of anti-cancer strategies but also for other physiological conditions where hypoxia results in disease manifestation.

Abstract
Melanoma is the deadliest form of skin cancer being responsible for 80% of skin cancer deaths. Furthermore, the incidence of metastatic melanoma has increased over the past three decades with a mortality rate that continues to rise faster than most of all other cancers. The last few years have witnessed an unparalleled change in treatment options for patients with metastatic melanoma by the development of new therapeutic strategies like targeted therapies and immunotherapies that highly improved the patient's prognosis. Despite the paradigm- shifting success of these novel treatments, their effectiveness is still limited by intrinsic or acquired resistance. The objective of this review is to provide an overview of the new available treatment modalities, criteria to select patients who might benefit from a specific therapy, mechanisms of innate and acquired resistance to these treatments and to discuss strategies to overcome drug resistance.

Abstract
In humans, the adaptive immune system uses the exchange of information between cells to detect and eliminate foreign or damaged cells; however, the removal of unwanted cells does not always require an adaptive immune system1,2. For example, cell selection in Drosophila uses a cell selection mechanism based on 'fitness fingerprints', which allow it to delay ageing3, prevent developmental malformations3,4 and replace old tissues during regeneration5. At the molecular level, these fitness fingerprints consist of combinations of Flower membrane proteins3,4,6. Proteins that indicate reduced fitness are called Flower-Lose, because they are expressed in cells marked to be eliminated6. However, the presence of Flower-Lose isoforms at a cell's membrane does not always lead to elimination, because if neighbouring cells have similar levels of Lose proteins, the cell will not be killed4,6,7. Humans could benefit from the capability to recognize unfit cells, because accumulation of damaged but viable cells during development and ageing causes organ dysfunction and disease8-17. However, in Drosophila this mechanism is hijacked by premalignant cells to gain a competitive growth advantage18. This would be undesirable for humans because it might make tumours more aggressive19-21. It is unknown whether a similar mechanism of cell-fitness comparison is present in humans. Here we show that two human Flower isoforms (hFWE1 and hFWE3) behave as Flower-Lose proteins, whereas the other two isoforms (hFWE2 and hFWE4) behave as Flower-Win proteins. The latter give cells a competitive advantage over cells expressing Lose isoforms, but Lose-expressing cells are not eliminated if their neighbours express similar levels of Lose isoforms; these proteins therefore act as fitness fingerprints. Moreover, human cancer cells show increased Win isoform expression and proliferate in the presence of Lose-expressing stroma, which confers a competitive growth advantage on the cancer cells. Inhibition of the expression of Flower proteins reduces tumour growth and metastasis, and induces sensitivity to chemotherapy. Our results show that ancient mechanisms of cell recognition and selection are active in humans and affect oncogenic growth.

Abstract
FOXO proteins represent a subfamily of transcription factors that belong to the forkhead family. The study of FOXO target genes can be performed using Real-Time PCR (RT-PCR). The RT-PCR is a sensitive method that allows the detection and quantification of minute amounts of nucleic acids. In RT-PCR the accumulation of the amplicon is detected and measured as the reaction progresses. Here, we describe the application of RT-PCR technique to monitor the transcriptional activity of FOXO transcription factors.

Abstract
OBJECTIVE A minority of lesions found in the sellar region are non-adenomatous neoplastic, inflammatory, or cystic masses. Our study aims to describe the prevalence and characteristics of these lesions in a multidisciplinary pituitary outpatient clinic. DESIGN We conducted an observational study which included 36 patients (15.9% of those followed up in this outpatient clinic between 2006 and 2016 who had pituitary surgery) submitted to pituitary surgery with histological results showing a non-adenomatous sellar lesion. We evaluated clinical, radiological, and biochemical (pituitary function) characteristics during the pre-operative and post-operative period. RESULTS Thirty-six patients (50% female) with a mean age of 41.3 ± 21.9 years and a mean follow-up duration of 8.0 ± 9.0 years were included. Histologic diagnoses were divided into benign neoplasms (80.6%), malignant neoplasms (11.1%), inflammatory lesions (5.6%), and cystic masses (2.8%). The most common clinical presentation was headache (66.7%) and visual defects (61.1%). Forty-seven percent of patients had at least one pituitary axis insufficiency at the time of diagnosis. In the majority of cases (58.3%), a transsphenoidal approach was used for the initial pituitary surgery. Thirteen patients had more than one pituitary surgery and eight also had radiotherapy. At the time of data retrieval, five patients had no pituitary hormonal insufficiency and 13 patients had some visual defect improvement. CONCLUSIONS Although rare, non-adenomatous sellar lesions may be associated with significant causes of morbidity, such as hypopituitarism and visual defects, per se or due to the various treatment modalities employed. Moreover, since the lesions are difficult to distinguish from adenomas, these patients require a careful multidisciplinary approach.

Abstract
The recent approval of several agents have revolutionized the scenario of therapeutic management of metastatic renal cell carcinoma (RCC) allowing us to reach important clinical end points with extended patients' survival. Actually, every new drug approved has represented an important step forward to the improvement of patient's survival. On the other hand, we now understand that RCC includes a large group of tumor entities, each of them with different genetic and mutational alterations, but also showing different clinical behavior; a reason behind the needs of subtype specific personalized approach to therapy of RCC. Immunotherapy is gradually becoming a key factor in the therapeutic algorithm for patients with locally advanced or metastatic RCC. Due to the combination of potent treatment success and potentially deadly adverse effects from immune checkpoint inhibitors (ICI), gathering prognostic and predictive information about FDA-indicated tumors seems to be prudent. Robust and reliable biomarkers are crucial for patient's selection of treatments with immunomodulatory drugs. PD-L1 expression is a poor prognostic factor and predictive of better responses from both PD-1 and PD-L1 inhibitors in a variety of tumor types including RCC. Each FDA approved PD-1/PD-L1 drug is paired with a PD-L1 Immunohistochemistry (IHC) assay. Thus, there is need for improved knowledge and application of PD-1/PD-L1 IHC biomarkers in daily practice. IHC staining appears in membranous fashion. The atezolizumab approved IHC assay is unique in that only immune cell staining is quantified for the use of this assay in RCC. A single biomarker for patient selection may not be feasible, given that immune responses are dynamic and evolve over time. Biomarker development for ICI drugs will likely require integration of multiple biologic components like PD-L1 expression, TILs and mutational load. New methodological approaches based on digital pathology may be relevant since they will allow recognition of the biomarker and to objectively quantitate its expression, and therefore might produce objective and reproducible cut-off assessment. Multidisciplinary approach is very much needed to fully develop the current and future value of ICI in clinical practice.

Granular cell tumours (GCT) are rare, slow-growing, benign neoplasms that are usually located in the head and neck. They are more frequent in the female gender and typically have an asymptomatic clinical course, being diagnosed only at autopsy. Symptomatic GCT of the neurohypophysis are exceedingly rare, being less than 70 cases described so far. The authors report on a case of a 28-year-old male that presented to the Endocrinology clinic with clinical and biochemical evidence of hypogonadism. He also reported minor headaches without any major visual symptoms. Further laboratory tests confirmed hypopituitarism (hypogonadotrophic hypogonadism, central hypothyroidism and hypocortisolism) and central nervous system imaging revealed a pituitary macroadenoma. The patient underwent transcranial pituitary adenoma resection and the pathology report described a GCT of the neurohypophysis with low mitotic index. The reported case is noteworthy for the rarity of the clinicopathological entity. Learning points Symptomatic GCTs are rare CNS tumours whose cell of origin is not well defined that usually give rise to visual symptoms, headache and endocrine dysfunction.Imaging is quite unspecific and diagnosis is difficult to establish preoperatively.Surgical excision is challenging due to lesion's high vascularity and propensity to adhere to adjacent structures.The reported case is noteworthy for the rarity of the clinicopathological entity.

Abstract
Iron pill-induced injury of bronchial mucosa is a complication following accidental aspiration of an iron tablet. Oral iron supplementation is a common therapy, particularly among advanced-age patients, who are more prone to aspiration. However, iron pill aspiration has been rarely reported in the literature, usually under the format of short case reports, with only 32 cases published in the literature. The cytologic features suspicious for this rare but potentially lethal entity have been seldom described. We report a case of a patient diagnosed with iron pill-induced bronchial injury, after oral ferrous sulfate has been prescribed during a hospital admission for pneumonia. In the bronchial washing specimen, a background of necrotic cell debris and acute inflammation involving extracellular golden-brown fibrils positive for iron stains was seen, along with the yeast forms, which, in this clinical context could confirm the iron pill aspiration. Our aim is to highlight the cytology features associated with iron pill aspiration bronchitis, and to review the literature for the histologic, clinical, bronchoscopy, and treatment aspects.

Abstract
One of the major genetic insights into the pathogenesis of polycythaemia vera included the identification of the somatic point gain-of-function mutations in Janus kinase 2 gene-first JAK2V617F on exon 14, present in 95%-97% of the cases, and later on exon 12. In the literature, we can find some reported studies where different exon 12 mutations are identified. Unlike patients with JAK2V617F mutation in exon 14, the mutation at exon 12 is not usually associated with an increase in the three haematopoietic series (erythrocytosis, leucocytosis and thrombocytosis). It appears to be associated with a distinct syndrome, mostly characterised by isolated and more marked erythrocytosis, independently of the mutational variant. We report here the case of a patient who is JAK2exon 12 positive, presenting a novel mutation-c.1605G>T (p.Met535Ile)-associated with c.1612C>T (p.His538Tyr) mutation previously described, evidencing an atypical clinical phenotype.

Abstract
Breast cancer epidemiological patterns vary in European countries, which present different incidence rates. Data have suggested that the reduction in breast cancer mortality is not only due to the early detection of the disease, but is, in almost equal part, due to screening and to the advances that have been made in molecular medicine and the development of novel therapies. The aim of the present study is to quantify the actual number of cases of breast cancer present in both of the sexes by calculating the prevalence of silent breast cancer in corpses. To achieve this quantification, bilateral subcutaneous radical mastectomies are performed in corpses of either sex above 40 years of age that lacked any clinical manifestation of the disease, and where the breast cancer or its complications was not the cause of death. Only five publications exist in the international literature based on medico-legal autopsies that were designed to define the ‘natural reservoir’ of the disease. To the best of our knowledge, the present study is the first one to appraise breast tissue via imaging by means of orienting the biopsy incision. In conclusion, to the best of our knowledge, the design of the present study is the first of its type, where image-guided biopsies are used to define the prevalence of silent breast cancer. The study aims to demonstrate that the ‘disease reservoir’ is, in reality, higher than was originally considered to be so. Furthermore, the study aims to contribute towards an improved definition of the disease by determining which tumour profiles potentially do not benefit from aggressive treatments (for example, in case where a high prevalence of low-grade ductal carcinoma in situ is to be detected). According to our pilot study, this analysis represents a feasible protocol.

Abstract
The diagnosis of tuberculosis is seriously hampered in the absence of standard biosafety laboratory facilities for specimen concentration and Mycobacterium tuberculosis culture. Within a laboratory twinning arrangement, heat-fixed direct smear and sediment from 74 bleach-processed and 20 non-processed specimens from Cumura Hospital, Guinea-Bissau, were sent to Lisbon for molecular evaluation of rifampicin resistance. Sequence analysis of a 369 base-pair rpoB locus detected 3.2% (3/94) resistant specimens. To our knowledge, this represents the first report on the molecular analysis of M. tuberculosis from bleach-processed sputum, an alternative to current diagnostic practice in low-resource settings.

Abstract
The adrenergic system has long been known to be activated in a situation of stress and thus during opiate withdrawal. A method for detoxification that decreases the stimulation of the sympathetic nervous system will prevent changes of catecholamine levels. Some of such methods have been developed. One of them uses direct transition from heroin to oral naltrexone after deep sedation with midazolam in conjunction with naloxone, droperidol, ondansetron, and clonidine treatment for 24 hours. Can such method prevent adrenergic changes? Moreover, 5-HT has been related to mood disorders. This study aims to determine plasma catecholamines and 5-HT before heroin withdrawal, during the day of the withdrawal, and at the ends of the first day, the first week, and the first 6 months. Forty-three patients with more than 6 years of drug abuse volunteered to seek help to detoxify. After clinical evaluation, blood samples were taken. Plasma catecholamines were isolated by standard alumina procedures and measured by high-performance liquid chromatography with electrochemical detection. Only for NE was there a significant decrease in the day of heroin withdrawal with deep sedation, followed the next day by an increase. During the following days, NE plasma concentrations returned slowly to basal levels. Epinephrine and dopamine plasma levels did not significantly change. Platelet 5-HT levels progressively decreased from the day before detoxification until the last period of observation. We also found that there were no abrupt changes in cardiovascular functions. In conclusion, our results suggest that this type of ultrarapid opiate detoxification prevents the dramatic activation of the autonomic nervous system.
