Abstract
INTRODUCTION AND IMPORTANCE Fine needle aspiration is the standard method for the pathological evaluation of pancreatic masses. In the following context, rare variants of such masses might present a challenge. Our goal is to describe the clinical, cytological, and histological findings of two cases of undifferentiated carcinoma with osteoclast-like giant cells (UCOCGC) a rare variant of pancreatic ductal adenocarcinoma (PDAC). CASE PRESENTATION Two cases were identified. Cytological findings exhibit similarities between the two cases. One patient received multiple chemotherapy regimens and a surgery and recurred within three years of diagnosis, while the other succumbed to cholangitis resulting from hepatic metastases a year after their initial surgery. DISCUSSION UCOCGC is a rare variant of pancreatic cancer, characterized by a unique cytological aspect. Recognizing this variant is essential considering its distinct prognosis compared to usual pancreatic adenocarcinoma. CONCLUSION We presented two cases of UCOCGC a rare pancreatic cancer variant, exposing diagnostic particularities and clinical evolution.

Abstract
In the past few years, numerous new insights have been gained in the field of giant cell tumor of bone (GCTB). On the one hand, the detection of the highly characteristic histone mutation in the H3F3A gene in GCTB is becoming increasingly important in diagnostics in differentiating GCTB from other giant cell-rich lesions of bone as well as for defining rare variants of GCTB without osteoclastic giant cells. On the other hand, the effects of the H3F3A mutation were shown to have an impact on the epigenetic profile of tumor-driving stromal cells, providing new insights into tumorigenesis of GCTB.

Abstract
Idiopathic Granulomatous Mastitis (IGM) is an infrequent, benign breast disease that primarily affects women during their childbearing years and can be mistaken for breast cancer. This study aimed to review the clinical, radiological, and histopathological findings of patients with IGM in addition to management and outcome. Retrospective cross-sectional study of biopsy-confirmed IGM at an academic medical center and a private hospital in Amman, Jordan. Fifty-four patients were included, with a mean age of 37.0 ± 9.04 years, mostly presenting with a breast lump (n = 52, 96.3%) and breast pain (n = 45 patients, 84.9%). Approximately half of the patients (51.9%) were parous, and 50% had breastfed for an average duration of 30.37 ± 22.38 months. Most of the patients had either solitary or multiple abscesses on breast ultrasound. Histopathological analysis (n = 35) showed mostly either moderate inflammation (n = 16, 45.7%) or severe inflammation (n = 14, 40%). Two-thirds of the patients underwent surgical interventions at the time of diagnosis, mostly incision and drainage (n = 16, 29%) or surgical excision (n = 7, 13%), and no mastectomies were performed. The most common medical treatment included a combination of antibiotics, corticosteroids, and methotrexate (n = 21, 38.8%). After follow-up, 31 patients remained in remission, 3 experienced relapses, and 3 had a chronic course. The use of corticosteroids was significantly associated with remission (p = 0.035). The presentation and demographics of IGM patients in Jordan were consistent with the existing literature. Prospective research is needed to explore different treatment options and disease outcomes.

Abstract
Central giant cell granuloma (CGCG) is a benign jaw lesion with variable clinical behavior. Cell cannibalism is a cellular process associated with aggressiveness and invasion in malignant neoplasms. Here, we morphologically investigated cell cannibalism as an auxiliary method to predict CGCG clinical behavior. Cell cannibalism was quantitatively evaluated in 19 cases of peripheral giant cell granuloma (PGCG), 38 cases of CGCG (non-aggressive and aggressive), and 19 cases of giant cell tumor of bone (GCT) stained with hematoxylin and eosin. T-test was performed to assess the differences between the variables analyzed (p ≤ 0.05). Cell cannibalism was identified in 21% of non-aggressive CGCGs and 68.4% of aggressive CGCGs. A significantly higher amount of cannibal multinucleated giant cells (CMGC) was observed in aggressive CGCG compared to PGCG and non-aggressive CGCG (p = 0.042; p = 0.044, respectively). There were no significant differences in the CMGC index between non-aggressive CGCG and PGCG (p = 0.858) and between aggressive CGCG and GCT (p = 0.069). CGGC cases that exhibited rapid growth and tooth displacement and/or root resorption had a higher amount of CMGC (p = 0.035; p = 0.041, respectively). Cell cannibalism can be identified in CGCG through routine anatomopathological examination. The quantification of CMGC can help to predict the clinical behavior of central giant cell granuloma.

Abstract
This report describes an unusual and diagnostically challenging case of subcutaneous soft tissue xanthogranulomas of bilateral orbits of a 58-year-old female patient seen in a private oculoplastics practice. Accurate and timely diagnosis is crucial in xanthogranulomatous diseases so that any systemic manifestations can be identified and addressed in a multidisciplinary fashion. Periorbital xanthogranuloma is a frequent early manifestation of adult xanthogranulomatous disease, and its association with life-threatening systemic disease requires accurate diagnosis and prompt work-up. This case describes an otherwise asymptomatic patient who presented with bilateral orbital masses causing visually significant ptosis, initially diagnosed as soft tissue xanthomas, and later identified as xanthogranulomas. It is important for physicians of all fields, from primary care to surgical subspecialty, to be aware that xanthogranulomatous disease may first present as periorbital lesions and/or orbital masses, and that further work-up for vision and life-threatening systemic disease is warranted.

Abstract
Myelodysplastic syndromes (MDS) are incurable diseases characterized by dysplastic hematopoietic cells, cytopenias in the blood and an inherent tendency for transformation to secondary acute myeloid leukemia (AML). Since most therapies fail to prevent rapid clonal evolution and disease resistance, new and non-invasive predictive markers are needed to monitor patients and adapt the therapeutic strategy. By using ISET, a very sensitive approach to isolate cells larger than mature leukocytes from peripheral blood samples, we looked for cellular markers in 99 patients (158 samples) with MDS and 66 healthy individuals (76 samples) used as controls. We found a total of 680 Giant Cells, defined as cells having a size of 40 microns or larger in 46 MDS patients (80 samples) and 28 Giant Cells in 11 healthy individuals (11 samples). In order to understand if we had enriched from peripheral blood atypical cells of the megakaryocyte line, we studied the Giant Cells using immunolabeling with megakaryocytes and tumor-specific markers. We report that the Giant Cells we found in the peripheral blood of MDS patients primarily express tumor markers. Our results show that Polyploid Giant Cancer Cells (PGCC), similar to those described in solid tumors, are found in the peripheral blood of patients with MDS and suggest the working hypothesis that they could play a role in hematological malignancies.

Abstract
Introduction The distinction between giant cell tumors and giant cell granulomas is challenging, as both entities have overlapping diagnostic criteria, especially in oral locations. The two entities have similar clinical and radiological presentations, but they differ in their prognoses. Objective The main objective of this study was to list the clinical, radiological, histological, and prognostic features of maxillomandibular giant cell tumors and giant cell granulomas cases n order to assess their value as a diagnostic referral factor that may allow the distinction between maxillo-mandibular giant cell granuloma and giant cell tumor. Study design Data of maxillomandibular giant cell granulomas and giant cell tumors were assessed through a scoping review and a pre-existing systematic review of literature. We have also realized a bicentric retrospective study. Results Various criteria facilitate the differential diagnosis like age, size, locularity and presence of necrosis zone but not the gender. The most discriminating factors was symptomatology (reported in 72% of GCTs while only 15% of GCGs) and the distribution pattern of giant cells in the stroma (homogeneously dispersed in 80% of GCTs versus grouped in clusters in 86.7% of GCGs). Recurrences were most described for giant cell tumors than giant cell granulomas. Malignant transformation and pulmonary metastasis were exclusively reported for giant cell tumors. Conclusion As clinical and radiological elements are not sufficient to distinguish between these two entities, immunohistochemistry and molecular genetics can be represent diagnostic biomarkers to distinguish giant cell granulomas and giant cell tumors in oral cavity. We have attempted to define the main criteria for the differentiation of giant cell tumor and giant cell granuloma and propose a decision tree for the management of single maxillomandibular giant cell lesions.

Abstract
Three types of nematode-feeding sites (NFSs) caused by M. graminicola on rice were suggested, and the NFS polarized expansion stops before the full NFS maturation that occurs at adult female stage. Root-knot nematodes, Meloidogyne spp., secrete effectors and recruit host genes to establish their feeding sites giant cells, ensuring their nutrient acquisition. There is still a limited understanding of the mechanism underlying giant cell development. Here, the three-dimensional structures of M. graminicola-caused nematode-feeding sites (NFSs) on rice as well as changes in morphological features and cytoplasm density of the giant cells (GCs) during nematode parasitism were reconstructed and characterized by confocal microscopy and the Fiji software. Characterization of morphological features showed that three types of M. graminicola-caused NFSs, type I-III, were detected during parasitism at the second juvenile (J2), the third juvenile (J3), the fourth juvenile (J4) and adult female stages. Type I is the majority at all stages and type II develops into type I at J3 stage marked by its longitudinal growth. Meanwhile, NFSs underwent polarized expansion, where the lateral and longitudinal expansion ceased at later parasitic J2 stage and the non-feeding J4 stage, respectively. The investigation of giant cell cytoplasm density indicates that it reaches a peak at the midpoint of early parasitic J2 and adult female stages. Our data suggest the formation of three types of NFSs caused by M. graminicola on rice and the NFS polarized expansion stopping before full NFS maturation, which provides unprecedented spatio-temporal characterization of development of giant cells caused by a root-knot nematode.

Abstract
Background Granulomatous interstitial nephritis in sarcoidosis (sGIN) is generally clinically silent, but in <1% causes acute kidney injury (AKI). Methods This Italian multicentric retrospective study included 39 sarcoidosis-patients with renal involvement at renal biopsy: 31 sGIN-AKI, 5 with other patterns (No-sGIN-AKI), 3 with nephrotic proteinuria. We investigate the predictive value of clinical features, laboratory, radiological parameters and histological patterns regarding steroid response. Primary endpoint: incident chronic kidney disease (CKD) beyond the 1°follow-up (FU) year; secondary endpoint: response at 1°line steroid therapy; combined endpoint: the association of initial steroid response and outcome at the end of FU. Results Complete recovery in all 5 No-sGIN-AKI-patients, only in 45% (13/29) sGIN-AKI-patients (p=0.046) (one lost in follow-up, for another not available renal function after steroids). Nobody had not response. Primary endpoint of 22 sGIN-AKI subjects: 65% (13/20) starting with normal renal function developed CKD (2/22 had basal CKD; median FU 77 months, 15-300). Combined endpoint: 29% (6/21) had complete recovery and final normal renal function (one with renal relapse), 48% (10/21) had partial recovery and final CKD (3 with renal relapse, of whom one with basal CKD) (p=0.024). Acute onset and hypercalcaemia were associated to milder AKI and better recovery than subacute onset and patients without hypercalcaemia, women had better endpoints than men. Giant cells, severe interstitial infiltrate and interstitial fibrosis seemed negative predictors in terms of endpoints. Conclusions sGIN-AKI-patients with no complete recovery at 1°line steroid should be treated with other immunosuppressive to avoid CKD, in particular if males with subacute onset and III stage-not hypercalcaemic AKI.

Abstract
PURPOSE The aim of this study was to evaluate the presence and distribution of multinucleated giant cell (MGC) reactions in 61 cases of OTSCC and to verify the association of this microscopic finding with clinicopathological parameters (gender, age, tumor size/extent, regional lymph node metastasis, distant metastasis, clinical stage, and histopathological grade of malignancy). METHODS Clinical data were collected from medical records and the histopathological grade of malignancy of OTSCCs was evaluated using the World Health Organization (WHO) grading system. The presence and distribution of MGC reaction in high power fields (HPFs) were evaluated in hematoxylin-eosin-stained histological sections. In all cases containing MGCs, immunohistochemical analysis for CD68 was performed in order to confirm the histiocytic nature of these cells. RESULTS Twenty-one (34.4%) cases had MGC reactions, with a higher frequency of the focal distribution pattern (57.1%). All MGCs were immunohistochemically positive for CD68. The absence of MGC reaction was significantly associated with regional lymph node metastasis (PR: 2.75; 95% CI 1.05-7.20; p = 0.027), advanced clinical stage (PR: 3.37; 95% CI 1.28-8.85; p = 0.006), and moderately/poorly differentiated tumors (PR: 3.36; 95% CI 1.51-7.48; p = 0.001). No significant associations were observed between the distribution of MGCs and clinicopathological parameters (p > 0.05). CONCLUSION Taken together, the results of this study suggest that the absence of MGC reaction may represent an indicator of tumor progression in OTSCCs.

Abstract
Root-knot nematodes are endoparasites whose mature females lodge and grow inside the root of some cultivated plants, leading to losses in productivity. Herein, we investigated if the infection of okra, Abelmoschus esculentus (Malvaceae), promoted by the root-knot nematode Meloidogyne incognita (Meloidogynidae) changes some agronomic traits of the host plant, as well as the cell wall composition of the root tissues. The okra Santa Cruz 47® cultivar was infected with a suspension of 5000 M. incognita juveniles. The inoculated and non-inoculated okra plants were then submitted to morphological analysis at the end of experiment, as well as histological (at 4, 11, 18, 39, ad 66 days after inoculation) and immunocytochemical analysis (control and 66 days after inoculation). Root-knot nematode infection reduced the dry weight of the stem system but, unexpectedly, the number and weight of fruits increased. At 11 days after inoculation, we detected the presence of giant cells that increased in number and size until the end of the experiment, at 66 days after inoculation. These cells came from the xylem parenchyma and showed intense and moderate labeling for epitopes recognized by JIM5 and JIM7. The presence of homogalacturonans (HGs) with different degrees of methyl esterification seems to be related to the injuries caused by the nematode feeding activity and to the processes of giant cell hypertrophy. In addition, the presence of HGs with high methyl-esterified groups can increase the cell wall porosity and facilitate the flux of nutrients for the root-knot nematode.

Abstract
There are multiple lesions in the jawbones with a common histological character of the presence of osteoclast-like giant cells under one category - giant cell lesions. The central giant cell granuloma (CGCG) is the most common of all and is found to be more prevalent in the Indian population. The pathogenicity still remains an enigma and needs to be differentiated from other look-alike lesions in order to have proper treatment planning. Furthermore, CGCG specifically needs to be differentiated from central giant cell tumor to avoid mutilating surgeries. This article is an attempt to give an outline of the CGCG with updating of the latest information on the perception of this lesion.

Abstract
Leprosy is an ancient insidious disease caused by Mycobacterium leprae, where the skin and peripheral nerves undergo chronic granulomatous infections, leading to sensory and motor impairment with characteristic deformities. Susceptibility to leprosy and its disease state are determined by the manifestation of innate immune resistance mediated by cells of monocyte lineage. Due to insufficient innate resistance, granulomatous infection is established, influencing the specific cellular immunity. The clinical presentation of leprosy ranges between two stable polar forms (tuberculoid to lepromatous) and three unstable borderline forms. The tuberculoid form involves Th1 response, characterized by a well demarcated granuloma, infiltrated by CD4+ T lymphocytes, containing epitheloid and multinucleated giant cells. In the lepromatous leprosy, there is no characteristic granuloma but only unstructured accumulation of ineffective macrophages containing engulfed pathogens. Th1 response, characterised by IFN-γ and IL-2 production, activates macrophages in order to kill intracellular pathogens. Conversely, a Th2 response, characterized by the production of IL-4, IL-5 and IL-10, helps in antibody production and consequently downregulates the cell-mediated immunity induced by the Th1 response. M. lepare has a long generation time and its inability to grow in culture under laboratory conditions makes its study challenging. The nine-banded armadillo still remains the best clinical and immunological model to study host-pathogen interaction in leprosy. In this chapter, we present cellular morphology and the genomic uniqueness of M. leprae, and how the pathogen shows tropism for Schwann cells, macrophages and dendritic cells.

Abstract
In order to understand events and mechanisms present in the pathophysiology of tilapia's chronic inflammation and based on the immunomodulatory activity attributed to cyclophosphamide which is widely used to suppress immune responses in human medicine, the present study investigated the effects of cyclophosphamide (CYP) treatment on the modulation of foreign body inflammatory reaction in Nile tilapia (Oreochromis niloticus) with round glass coverslip implanted in the subcutaneous tissue (9 mm of diameter). Forty tilapia (151 ± 10,2 g) were randomly distributed in 5 aquariums (n = 8) with a capacity of 250 L of water each, to compose two treatments (sampled 3 and 6 days post-implantation): implanted/untreated (control) and implanted/treated with 200 mg of CYP kg-1 of b.w., through i.p. route. A fifth group (n = 8) was sampled without any stimulus (naive) to obtain reference values. CYP-treated tilapia showed decrease in macrophage accumulation, giant cell formation and Langhans cells on the glass coverslip when compared to control fish. The treatment with CYP resulted in decrease of leukocyte and thrombocyte counts. Decrease in alpha-2-macroglobulin, ceruloplasmin, albumin and transferrin levels, as well as increase in haptoglobin, complement C3 and apolipoprotein A1 were observed in tilapias during foreign body inflammation. Blood levels of complement C3, alpha-2-macroglobulin, ceruloplasmin and transferrin were modulated by treatment with CYP. Therefore, the treatment with 200 mg of CYP kg-1 of b.w. in tilapia resulted in an anti-inflammatory effect by suppressing the dynamics between leukocytes in the bloodstream and macrophage accumulation with giant cell formation in the inflamed focus, as well as by modulating APPs during foreign body reaction.

Abstract
Background Osteosarcoma is a malignant tumor of the bone. The giant cell-rich osteosarcoma (GCRO) is a rare histological variant of the conventional osteosarcoma, accounting for 3% of all osteosarcomas. It has a variable clinical presentation, ranging from asymptomatic to multiple pathological fractures, mainly involving long bones, and less frequently the axial skeleton and soft tissues. Case presentation We present the case of a 25-year-old Hispanic woman, previously healthy, with a 1-month history of dyspnea on exertion, intermittent dry cough, hyporexia, and intermittent unquantified fever. She presented to the emergency department with a sudden increase in dyspnea during which she quickly entered ventilatory failure and cardiorespiratory arrest with pulseless electrical activity. Resuscitation maneuvers and orotracheal intubation were initiated, but effective ventilation was not achieved despite intubation and she was transferred to the intensive care unit of our institution. The chest radiograph showed a mediastinal mass that occluded and displaced the airway. The chest tomography showed a large mediastinal mass that involved the pleura and vertebral bodies. A thoracoscopic biopsy was performed that documented a conventional giant cell-rich osteosarcoma. The patient was considered to be inoperable due to the size and extent of the tumor and subsequently died. Conclusions The giant cell-rich osteosarcoma is a very rare histological variant of conventional osteosarcoma. Few cases of this type of osteosarcoma originating from the spine have been reported in the literature, and to our knowledge none of the reported cases included invasion to the chest cavity with airway compression and fatal acute respiratory failure that was present our case. Radiological and histological features of the GCRO must be taken into account to make a prompt diagnosis.

Abstract
Pulmonary pleomorphic carcinoma (PPC) is a poorly differentiated non-small cell lung carcinoma, including squamous cell carcinoma, adenocarcinoma, or undifferentiated non-small cell lung carcinoma with at least 10% spindle and/or giant cells. Here, we report a case of PPC showing undifferentiated non-small cell lung carcinoma with giant cells. A 71-year-old man with dyspnea underwent right lobectomy because of a mass in the right upper lobe of the lung. A 5.0 × 3.0 × 1.5 cm-sized tumor was identified; microscopically, the tumor composed of undifferentiated large sized tumor cells admixed with syncytial tumor giant cells and emperipoletic giant cells. Immunohistochemically, the tumor cells were reactive for pan-cytokeratin, but negative for P40, thyroid transcription factor 1 (TTF-1), and vimentin. The tumor cells were also positive for 3 clones of programmed death-ligand 1 (PD-L1). The clinical and histologic findings supported the diagnosis of an undifferentiated non-small cell lung carcinoma with giant cells, which is a subtype of pulmonary pleomorphic carcinoma. Unfortunately, after surgery, multifocal lymph node metastasis was identified in radiologic examination. Only palliative chemotherapy was administered to the patient, although he was indicated for immunochemotherapy. Pulmonary pleomorphic carcinoma is known to have a poor prognosis, even in early stages of the disease, therefore, we should be careful in the diagnosis to ensure optimal treatment.

Abstract
Root-knot nematodes (RKNs) are highly invasive plant parasites that establish permanent feeding sites within the roots of the host plant. Successful establishment of the feeding site is essential for the survival of RKN. The formation and development of the feeding cell, also called giant cell, involve both cell division and endoreduplication. Here, we examined giant cell development and endoreduplication in Prunus sogdiana infected with the RKN. We found that feeding sites were established 3-5 days post inoculation (dpi) and matured at 21-28 dpi. The giant cells began to form 5 dpi and continued to increase in size from 7 to 21 dpi. The large numbers of dividing nuclei were observed in giant cells from 7 to 14 dpi. However, nuclear division was rarely observed after 28 days. RT-PCR and in situ hybridization analyses revealed that PsoCCS52A was abundantly expressed at 7-21 dpi and the PsoCCS52A signal observed in giant cell nucleus at 7-14 dpi. The PsoCCS52B is highly expressed at 14 dpi, and the hybridization signal was mainly in the cytoplasm of giant cells. The PsoDEL1 expression was lowest 7-21 dip, with negligible transcript detected in the giant cells. This indicates that the PsoCCS52A plays a role in the process of cell division, while the CCS52B plays a role in the development of giant cells. The PsoDEL1 plays a negative regulatory role in megakaryocyte nuclear replication. These data suggest that an increased expression of PsoCCS52A promotes nuclear division and produces a large number of polyploid nuclei, the area of giant cells and feeding sites increase, ultimately leading to the formation of galls in Prunus sogdiana.

Abstract
Tuberous sclerosis (TSC) is a multisystem autosomal dominant genetic disorder due to loss of function of TSC1/TSC2 resulting in increased mTOR (mammalian target of rapamycin) signaling. In the brain, TSC is characterized by the formation of specific lesions that include subependymal and white matter nodules and cortical tubers. Cells that constitute TSC lesions are mainly Giant cells and dysmorphic neurons and astrocytes, but normal cells also populate the tubers. Although considered as a developmental disorder, the histopathological features of brain lesions have been described in only a limited number of fetal cases, providing little information on how these lesions develop. In this report we characterized the development of TSC lesions in 14 fetal brains ranging from 19 gestational weeks (GW) to term and 2 postnatal cases. The study focused on the telencephalon at the level of the caudothalamic notch. Our data indicate that subcortical lesions, forming within and at the vicinity of germinative zones, are the first alterations (already detected in 19GW brains), characterized by the presence of numerous dysmorphic astrocytes and Giant, balloon-like, cells. Our data show that cortical tuber formation is a long process that initiates with the presence of dysmorphic astrocytes (by 19–21GW), progress with the apparition of Giant cells (by 24GW) and mature with the appearance of dysmorphic neurons by the end of gestation (by 36GW). Furthermore, the typical tuberal aspect of cortical lesions is only reached when bundles of neurofilament positive extensions delineate the bottom of the cortical lesion (by 36GW). In addition, our study reveals the presence of Giant cells and dysmorphic neurons immunopositive for interneuron markers such as calbindin and parvalbumin, suggesting that TSC lesions would be mosaic lesions generated from different classes of progenitors.

Abstract
Laser capture microdissection (LCM) has become a powerful technique that allows analyzing gene expression in specific target cells from complex tissues. Widely used in animal research, still few studies on plants have been carried out. We have applied this technique to the plant-nematode interaction by isolating feeding cells (giant cells; GCs) immersed inside complex swelled root structures (galls) induced by root-knot nematodes. For this purpose, a protocol that combines good morphology preservation with RNA integrity maintenance was developed, and successfully applied to Arabidopsis and tomato galls. Specifically, early developing GCs at 3 and 7 days post-infection (dpi) were analyzed; RNA from LCM GCs was amplified and used successfully for microarray assays.

Abstract
Cryptococcosis is a potentially fatal fungal disease which has aggrandized with the emergence of AIDS and antifungal resistance. The currently used antifungals lack the broad-spectrum activity and result in several toxicities during long treatment regimens. Thus, the present study aims to evaluate the antifungal activity of cinnamaldehyde against Cryptococcus neoformans var. grubii, the etiological agent of the disease. Quantitative and qualitative in vitro fungal susceptibilities were carried out by minimum inhibitory concentration assay, flow cytometric analysis, and confocal microscopy. Micromorphological alterations were studied through scanning electron and light microscopies. "In vivo" antifungal efficacy of cinnamaldehyde was assessed. Cinnamaldehyde showed antifungal activity against C. neoformans in a dose-dependent manner. A concentration of 1.37 mg/mL of cinnamaldehyde was found to be inhibitory and fungicidal while the low concentration (0.68 mg/mL) was found to induce micromorphological changes and formation of giant/titan-like cells in this pathogen. The reparative activity of cinnamaldehyde and its ability to prolong the life even after the advent of cryptococcal meningitis in mice was also noticed. This study suggests potent anti-cryptococcal activity of cinnamaldehyde. Though, it has a couple of limitations like allergy and low bioavailability. However, these problems can be circumvented by developing suitable analogs of the compound. It, therefore, could be used as a therapeutic option against cryptococcosis and cryptococcal meningitis. Moreover, the evaluation of its pharmacokinetic and pharmacodynamic properties is desirable.

Abstract
Multinucleate cell angiohistiocytoma is a rare, benign vascular proliferation of unknown etiology. It occurs mainly in middle-aged women and usually affects the acral regions; the lesions appear as discrete, grouped, and asymptomatic violaceous papules. Histopathology shows proliferation and dilated small vessels in the papillary dermis, fibrous stroma with thickened collagen bundles, and multinucleated giant cells. To date, there are approximately 140 cases described in the indexed literature. This report presents the case of a 62-year-old woman with a typical clinical condition, who chose not undergo treatment, considering the benign character of her illness. The clinical and immunohistological aspects of this unusual dermatological entity are emphasized.

Abstract
Craniopharyngioma is an uncommon intracranial tumor that primarily occurs in the sella turcica. Giant cystic craniopharyngioma is rare in general and extremely rare in adults. We report a rare case of giant cystic craniopharyngioma in the anterior pontine cisterna and suprasellar cisterna. A 27-year-old man presented with double vision, and craniocerebral MRI revealed cystic masses in the anterior pontine cisterna and suprasellar cisterna. The masses were removed surgically and diagnosed as large cystic craniopharyngiomas by pathology and MRI. Giant cystic craniopharyngioma is rare in adults. Through this case report, we hope to increase awareness of this disease among various clinicians, including radiologists.

Abstract
Noonan syndrome (NS) is a relatively common congenital multiple-anomaly syndrome, resembling Turner syndrome, but without chromosomal anomaly. Besides the unusual facies, the maxillofacial and dental features of patients with NS are not well-summarized in the literature. The aim of this study was to describe these features and propose specific treatment guidelines for practitioners involved in oral and maxillofacial care. A retrospective multicentric study was conducted of 14 patients who were referred for NS screening. In total, 10 patients were found to carry a mutation involved in NS or NS-related disorders. Fifty percent of the mutations affected PTPN11. All patients presented with the typical extraoral features, such as macrocephaly, hypertelorism, ptosis, triangular face shape and ear dystrophy. Intraoral manifestations, including malocclusion (maxillary transversal deficiency, crossbite, anterior open-bite and class II malocclusion), dental anomalies (delayed eruption, agenesis and dystrophy, odontoma) and radiologic jaw lesions were identified in five out of 10 patients. These findings were searched in a review of the literature to obtain a comprehensive description of oral and maxillofacial features in patients with NS. The proposed treatment guidelines emphasize frequent coagulation anomalies that need to be considered prior to surgery. Early dental assessment and yearly follow-up with oral prophylaxis are recommended. Orthodontics and orthognathic surgery are also of primary importance in the management of NS patients.

Abstract
Germline mutations of the POLE gene are responsible for polymerase proofreading-associated polyposis syndrome (PPAP). These mutations were hypothesised to predispose to extra-gastrointestinal tumours (ovary, endometrium, brain), but this association has not been confirmed so far. We report a family with an autosomal dominant inheritance of PPAP due to a c.1089C>A; p.Asn363Lys mutation in the proofreading exonuclease domain of POLE. Ten patients presenting a history of colorectal tumours and three patients with polyposis are indexed in this family. Three carriers (including siblings and a distant cousin at 30, 45 and 52 respectively) and another member (at 37 not tested) presented glioblastoma. This is the second family reported to carry this mutation. Among the four glioblastomas in the family that we report, both show similar pathology: giant cell glioblastoma. These cases suggest that the c.1089C>A germline POLE mutation may confer an increased risk of brain cancer [incidence 17.4% (4/23) in mutation carriers combining the two families]. More observations are needed to support this hypothesis. It seems that not all mutations of POLE are equally associated with extra-gastrointestinal tumours. Although carriers of a mutation responsible for PPAP should benefit from screening for colorectal and uterine cancer, due to the rapid evolution of glioblastoma the value of neurological follow-up and brain imaging screening remains questionable. Nevertheless, considering the limitations of standard therapy for glioblastoma, mutation status could be useful for targeting therapy. The biological mechanism linking POLE mutation to glioblastoma remains to be determined.

Abstract
OBJECTIVE We describe the first case of a rare undifferentiated uterine sarcoma exhibiting both neuroectodermal differentiation and osteoclast-like giant cells, and elaborate its morphology. CASE REPORT A 54-year-old woman presented with suprapubic pain, frequent urination, and perimenopausal abnormal vaginal bleeding. Computed tomography revealed a large heterogeneous uterine mass and multiple lung nodules. She received a staging surgery. The tumor pathology examination revealed an undifferentiated uterine sarcoma (UUS) with neuroectodermal differentiation and osteoclast-like giant cells (OGCs). The patient was managed with palliative hospice care; however, she died within 1.5 months of diagnosis. CONCLUSION UUSs are rare high-grade tumors observed in elderly women. These women typically present with postmenopausal bleeding and extrauterine diseases and have a poor prognosis. Neuroectodermal differentiation in UUSs has a müllerian origin. The presence of OGCs may suggest a poor prognosis; however, further studies are necessary to determine the exact nature of such neoplasms.

Abstract
AIM Current development of novel systemic agents requires identification and monitoring of extensive Tenosynovial Giant Cell Tumours (TGCT). This study defines TGCT extension on MR imaging to classify severity. METHODS In part one, six MR parameters were defined by field-experts to assess disease extension on MR images: type of TGCT, articular involvement, cartilage-covered bone invasion, and involvement of muscular/tendinous tissue, ligaments or neurovascular structures. Inter- and intra-rater agreement were calculated using 118 TGCT MR scans. In part two, the previously defined MR parameters were evaluated in 174 consecutive, not previously used, MR-scans. TGCT severity classification was established based on highest to lowest Hazard Ratios (HR) on first recurrence. RESULTS In part one, all MR parameters showed good inter- and intra-rater agreement (Kappa≥0.66). In part two, cartilage-covered bone invasion and neurovascular involvement were rarely appreciated (<13%) and therefore excluded for additional analyses. Univariate analyses for recurrent disease yielded positive associations for type of TGCT HR12.84(95%CI4.60-35.81), articular involvement HR6.00(95%CI2.14-16.80), muscular/tendinous tissue involvement HR3.50(95%CI1.75-7.01) and ligament-involvement HR4.59(95%CI2.23-9.46). With these, a TGCT severity classification was constructed with four distinct severity-stages. Recurrence free survival at 4 years (log rank p < 0.0001) was 94% in mild localized (n56, 1 recurrence), 88% in severe localized (n31, 3 recurrences), 59% in moderate diffuse (n32, 12 recurrences) and 36% in severe diffuse (n55, 33 recurrences). CONCLUSION The proposed TGCT severity classification informs physicians and patients on disease extent and risk for recurrence after surgical treatment. Definition of the most severe subgroup attributes to a universal identification of eligible patients for systemic therapy or trials for novel agents.

Abstract
OBJECTIVES Brown tumours are benign bone tumours secondary to hyperparathyroidism. The authors describe the various clinical features, diagnostic methods and treatment modalities for maxillofacial brown tumours. MATERIAL AND METHODS This multicentre retrospective study comprised 5 patients (four women and one man, between the ages of 29 and 70 years) with one or several maxillofacial brown tumours observed over a 16-year period from January 2000 to December 2016. RESULTS Four patients presented secondary hyperparathyroidism in a context of chronic renal failure, one patient presented primary hyperparathyroidism due to parathyroid adenoma. Three patients presented a mandibular brown tumour, and two patients presented a maxillary brown tumour. The diagnosis was based on histological examination and laboratory tests. Brown tumours were treated either surgically or conservatively. A favourable outcome was observed in all cases. CONCLUSION Brown tumours are rare lesions. This diagnosis must be considered in a context of giant cell tumour associated with hyperparathyroidism. Brown tumours should be treated conservatively.

Abstract
Giant-cell fibroma is a localized, benign fibrous mucosal mass, which clinically mimics any other fibroepithelial growth, and its distinction from other lesions is on the basis of its peculiar histopathology. A case of giant-cell fibroma with stroma strewn with brown pigment-laden cells is presented herewith. Immunohistochemical staining aided with histochemical reaction to understand the origin of these cells was carried out. Various mechanisms that explain the presence of melanin granules in reactive lesions of giant-cell fibroma is discussed in the present report.

Abstract
Craniopharyngioma is a relatively benign intracranial tumour that involves sellar and supra-sellar regions. Spontaneous rupture of craniopharyngioma into the sub-arachnoid space or into the ventricles is a rare phenomenon and few cases are reported in literature. We hereby report a case of sellar-suprasellar craniopharyngioma with focal intra-parenchymal rupture into brain causing aggravation of headache in a 12-year-old female child. This complication is a relatively rare phenomenon, which requires attention for early intervention. This was managed by trans-nasal endoscopic trans-sphenoidal surgery. Usually rupture of craniopharyngioma causes chemical meningitis or it can be asymptomatic. Sometimes rupture can cause complete resolution of cyst and symptoms. In the present case, there was only focal rupture and it was into brain parenchyma causing brain oedema with aggravation of headache. Magnetic Resonance Imaging (MRI) in intra-parenchymal rupture of craniopharyngioma has been emphasized in this case report.

Abstract
A 28-year-old Syrian refugee presented with right-sided knee pain and progressive deterioration of the general condition over the past months. Laboratory diagnostics revealed severe hypercalcemia due to primary hyperparathyroidism, and computed tomography (CT) scanning demonstrated disseminated osteolytic lesions throughout the skeleton. Histologically, these lesions were characterized by multinuclear giant cells (defining these lesions as so-called brown tumors). Finally, surgical removal of a jugular mass allowed the histopathologic diagnosis of a sporadic parathyroid carcinoma. In the patient, this condition was associated with a mutation in the HPRT2 gene locus.

Abstract
We demonstrated an extremely unusual case of an 83-year-old male's sudden death secondary to characteristic myocardial necrosis and fibrosis with calcification and multinucleated giant cells infiltration, possibly due to sepsis and Stage IV pulmonary pleomorphic carcinoma-induced cachexia after postmortem study. We propose that this calcifying giant cell cardiomyopathy (CGC) would be a new entity especially from the pathological viewpoints and should be considered in the classification of noninfectious myocarditis. Further prospective studies are needed to validate the presence and significance of CGC and the association with any triggers of somewhat microvascular dysfunction and/or toxic agents, after collecting and investigating a larger number of CGC cases examined.

Abstract
Cyst nematodes are obligate biotrophs that induce the formation of a hypertrophied and hypermetabolic syncytial-feeding site in roots of the host plants. Cytokinin signaling is activated at the site of infection and contributes significantly to the formation of syncytium. Here, we describe a protocol for visualizing cytokinin signaling activation in Arabidopsis upon infection with cyst nematode Heterodera schachtii using promoter reporter lines, TCSn:GFP and ARR5:GUS.

Abstract
Multinucleated giant cells (MGC) are considered to be a hallmark of granulomatous inflammation; thus, they may play an essential role in the host response against pathogens, particularly Paracoccidioides brasiliensis. This study characterizes the MGC found in oral paracoccidioidomycosis and assesses the correlation of MGC with the amount of fungi within oral tissues. Twenty-six cases were included. They were classified as loose or dense granulomas, and the total MGC, including foreign-body and Langhans giant cells, besides the total and intracellular fungi, were taken into consideration. CD163 immunoexpression was performed, and CD163+ multinucleated giant cells were also quantified. Dense granulomas revealed more foreign-body type and total giant cells than loose granulomas (P < 0.05). Total giant cells showed a positive linear correlation with the CD163+ cells (P = 0.003; r = 0.56) and intracellular fungi quantification (P = 0.045; r = 0.40). Oral paracoccidioidomycosis lesions contain MGC that mainly belong to a CD163+ phenotype, also showing both Langhans and foreign-body arrangements. Additionally, the higher the presence of MGC, the higher the amount of phagocytized fungi.

Abstract
Mitosis which is a major step during plant development can also be observed in physiopathological conditions. During the compatible interaction between the root-knot nematode Meloidogyne incognita and its host Arabidopsis, the pathogen induce through repeated divisions without complete cytokinesis the formation of hypertrophied and multinucleate feeding cells, named giant cells. Due to the presence of hypertrophied plant cell material surrounding the giant cells, classical live cell imaging gave therefore very poor resolution. Here, we describe a protocol which allows the in vivo observation of the mitotic apparatus in developing giant cells using confocal imaging of vibrosliced tissues. This approach can also be used to visualize in vivo other cellular processes occurring in different steps of giant cells.

Abstract
Among plant-parasitic nematodes, the root-knot nematodes (RKNs) of the Meloidogyne spp. are the most economically important genus. RKN are root parasitic worms able to infect nearly all crop species and have a wide geographic distribution. During infection, RKNs establish and maintain an intimate relationship with the host plant. This includes the creation of a specialized nutritional structure composed of multinucleate and hypertrophied giant cells, which result from the redifferentiation of vascular root cells. Giant cells constitute the sole source of nutrients for the nematode and are essential for growth and reproduction. Hyperplasia of surrounding root cells leads to the formation of the gall or root-knot, an easily recognized symptom of plant infection by RKNs. Secreted effectors produced in nematode salivary glands and injected into plant cells through a specialized feeding structure called the stylet play a critical role in the formation of giant cells. Here, we describe the complex interactions between RKNs and their host plants. We highlight progress in understanding host plant responses, focusing on how RKNs manipulate key plant processes and functions, including cell cycle, defence, hormones, cellular scaffold, metabolism and transport.

Abstract
Spitzoid melanoma is a subtype of melanoma that, clinically and histologically, resembles a Spitz nevus. Clinically, spitzoid melanomas usually evolve from amelanotic nodular lesions, growing to 1 cm or more in diameter. They often remain clinically undiagnosed because of their wide variety of clinical appearances and a lack of pigmentation. Distinguishing a Spitz nevus from a spitzoid melanoma can be extremely difficult. Features that favor the diagnosis of a spitzoid melanoma are asymmetrical shape, diameter greater than 1 cm, a lesion with a deep invasive component, and a high degree of cytologic atypia. There have been only rare reports in the literature of the presence of giant cells in malignant melanoma, and the presence of these cells may result in its misdiagnosis as a histiocytic tumor. We present a case of spitzoid melanoma on the right ankle of a 22-year-old-woman.

Abstract
The non-Hodgkin lymphoma is a neoplastic entity that presents in extranodal form in 20 % of cases, usually occurs as solitary or generalized lymphadenopathy. There may be misdiagnosis if it manifests as primary extranodal disease because the primary infiltration may occur with different organs, despite the difficulty of diagnosis of primary extranodal location of non-Hodgkin lymphoma, histological and immunohistochemical studies are effective in preventing misdiagnosis. The presentation of this case is to describe this condition in its extranodal variety with cardiac infiltration in a 23 year-old woman with progressive dyspnea. Tumor mass was detected in right-atrial, venous catheterization biopsy was performed, this enabled the histopathological diagnosis and establish treatment. We present experiences from the attention of the case and review of the literature with special reference to diagnosis and treatment.

Abstract
Hypersensitivity pneumonitis (HP) is an immunologically mediated form of diffuse lung disease, with histopathologic features that include cellular bronchiolitis, interstitial pneumonia, poorly formed granulomas, isolated multinucleated giant cells (MNGCs), organizing pneumonia, and interstitial fibrosis. This study describes the clinical and histopathologic findings in a retrospective series of 40 consecutive patients diagnosed with HP at the Mayo Clinic in Rochester, MN, between 1997 and 2011. Because the literature indicates that granulomas and MNGCs are located in the interstitium, particular attention was given to their distribution. Of the 40 patients, 33 underwent surgical lung biopsy and 7 underwent lung transplantation. Thirty-eight (95%) patients had interstitial pneumonia; 37 (93%), cellular bronchiolitis; 32 (80%), nonnecrotizing granulomas; 31 (78%), isolated MNGCs; 34 (85%) organizing pneumonia, and 31 (78%); interstitial fibrosis. In 27 cases, the granulomas were within airspaces; and in 26, they were interstitial. In 25 cases, MNGCs were within airspaces; and in 24, they were interstitial. In 3 (8%) cases, both granulomas and MNGCs were seen only within airspaces. Interstitial fibrosis was centrilobular in 22 cases, resembled usual interstitial pneumonia in 18 cases, and resembled nonspecific interstitial pneumonia in 11 cases. The "classic triad" of bronchiolitis, interstitial pneumonia, and granulomas was seen in 29 (73%) cases and was most frequent in biopsy than explant specimens (P = .004). This study confirms that granulomas and MNGCs are not confined to the pulmonary interstitium in HP.

Abstract
Giant cell interstitial pneumonia (GIP) is a rare form of chronic interstitial pneumonia typically associated with hard metal exposure. Only two cases of GIP induced by nitrofurantoin have been reported in the medical literature. We are reporting a case of recurrent nitrofurantoin-induced GIP. Although extremely rare, GIP needs to be included in the differential diagnosis in patients with chronic nitrofurantoin use who present with respiratory illness.

Abstract
Emperipolesis is an uncommon biological process, in which a cell penetrates another living cell. Unlike in phagocytosis where the engulfed cell is killed by lysosomal enzymes of the macrophage, the cell exists as viable cell within another in emperipolesis and can exit at any time without any structural or functional abnormalities for either of them. This process can either be physiological or pathological and may be a pathognomonic feature of certain diseases. Histiocytes and Megakaryocytes are involved in Emperipolesis normally but tumour giant cells in Hodgkin's disease and Rosai-Dorfman disease are pathologic conditions in which this process is seen. We report a mini review as this process is rare and not much reported in the literature.

Central giant cell granuloma is a fairly common lesion in the jaws aetiology of which is still completely unknown but thought to be of a reactive process to some unknown stimuli. It usually arises either peripherally in periodontal ligament, mucoperiosteum, or centrally in the bone. The histological hallmark for both peripheral and central giant cell granuloma (CGCG) is the presence of distinctive multinucleated giant cells (MGCs) in a prominent fibrous stroma. Central giant cell granuloma is an uncommon benign proliferative lesion that almost exclusively occurs within the jaw. Eventually, it may become aggressive leading to the expansion and perforation of cortex resulting into mobility and displacement of teeth with root resorption. The present case focuses on the dilemma and perplexity in diagnosing aggressive CGCGs, due to its close proximity with respect to pathology, behavior and prognosis from giant cell tumors (GCT). Central giant cell granuloma persuaded extensive destruction to the hard and soft tissues with high rate of recurrence encourage us the need of exploring the possibilities of giant cell tumors having a definitive presence in the jaws.

Abstract
Central giant cell granuloma formerly called as giant cell reparative granuloma is a non neoplastic proliferative lesion of unknown etiology. It occurs most commonly in mandible, but can also occur in maxilla. The case described here involved maxilla which was treated with surgical excision.
