Abstract
Testicular mixed germ cell tumors (TMGCTs) are rare malignant tumors comprising of two or more types of germ cell tumors. Their onset may be undetectable and the patient may first present with symptoms of metastasis. We hereby report a case of a young male who presented with respiratory discomfort and had no symptoms of primary testicular tumor. CT-guided FNAC lung revealed mainly necrotic, keratinous debris with a focus of chondromyxoid stroma. Differential diagnoses of components of teratoma, squamous cell carcinoma and inclusion cyst was considered. FNAC was reported out for the possible presence of teratoma components. Retrospectively, physical examination and subsequent USG revealed testicular tumor. The case led to a diagnostic dilemma as the patient presented with no prior history suggestive of metastasis from testicular mixed germ cell tumor. The aim of the current case report is to alert the pathologists and clinicians about this uncommon clinical presentation and diagnostic relevance of FNA. It highlights that FNA lung revealing keratinous material should always be searched for the possibility of teratoma component.

Abstract
Peritoneal malignant mesothelioma is an uncommon neoplasm with a poor prognosis. We hereby report a case of a 20-year-old male, first diagnosed on biopsy with axillary lymph node metastasis. He presented with abdominal pain and axillary lymphadenopathy, with no history of asbestos exposure. CECT showed peritoneal thickening and ascites. Ascitic fluid cytology showed reactive morphology. The diagnosis of metastatic deposits of malignant mesothelioma was made on histopathology and confirmed by immunohistochemistry. Tumor cells were immune-reactive for CK 5/6, calretinin, D2-40, and WT1 and negative for TTF1, CK 20, and CD 3. This case report has two important highlights-(i) unusual presentation with axillary lymph node metastasis leading to diagnostic dilemma in a young male with no asbestos exposure history and (ii) confirmatory diagnostic role of IHC in Peritoneal malignant mesothelioma.

Abstract
In developing/underdeveloped countries there is still a great burden of adverse drug reaction (ADR), morbidity and mortality because of poor regulations and implementation of preventive measures. These countries try to copy/follow guidelines from international bodies like American Urology Association (AUA), European Association of Urology (EAU), AGS, UMC and WHO irrespective of their country of origin and success in implementation. Although recommendations of these organizations are obligatory, yet these are taken as the gold standard for good clinical practices. This manuscript highlights difference in view point of various apex health organizations in formulating health policies for prevention, diagnosis, treatment and ADR monitoring for urological disorders. Lacking role of regulatory bodies in implementation of existing policies may lead to potentially inappropriate medication and produce a great economic burden. This analysis has prompted us to recommend that these apex bodies should have better coordination in producing a single value document, make it mandatory part of curricula in medical schools for better awareness, awareness campaigns and separate reporting column in ADR form.

Abstract
The field of "Cancer Genomics and Epigenomes" has been widely investigated for their involvement in cancer to understand the basic processes of different malignancies. The aggregation of genetic and epigenetic alterations also displays a wide range of heterogeneity making it quite necessary to develop personalized treatment strategies. The complex interplay between DNA methylation and chromatin dynamics in malignant cells is one of the major epigenetic mechanisms that lead to gene activation and repression. Hence, each tumor needs to be fully characterized to satisfy the ideas of personalized treatment strategies. The present article addresses various aspects of genome characterization methods and their potential role in the field of cancer genomics and epigenomics.

Abstract
Nanoclusters offer a fascinating possibility of studying the evolution of properties of a physical system by varying the number, size and inter-cluster separation of a given cluster to go from one limit to another. By systematically varying the inter-cluster separation in a nanocluster assembly of Ni40Pd60 alloy, that is known to be a metal in bulk, we observe an unusual and hitherto unreported, spatial dimension change as well as a change in the transport mechanism. In the nanocluster form, the temperature dependent resistance shows an activated behavior for virtually all inter-cluster separations, contrary to, the bulk metallic behaviour. At large average inter-cluster separation, the transport happens via three dimensional Efros-Shklovskii hopping, due to the opening of a Coulomb gap at the Fermi surface. With a reduction in the inter-cluster separation, the transport mechanism changes from three dimensional Efros-Shklovskii hopping to that of a three dimensional Mott variable range hopping (VRH) due to the closing up of the gap. With a further reduction in average inter-cluster separation, the three dimensional Mott VRH changes to that of a two dimensional Mott VRH with additional signatures of an insulator to a weak metal-like transition in this particular assembly. So, nanoclusters offer a paradigm for studying the important problem of evolution of charge transport in physical systems with the possibility of directly tuning the average inter-cluster separation enabling the system to go from insulating to metallic limit via intermediate changes in the charge transport mechanism.

Abstract
OBJECTIVE Circulating tumor cells are isolated tumor cells in the peripheral blood that serve as important prognostic indicators for many kind of tumors. The study was conducted to know the rate of detection of circulating tumor cells among breast cancer patients in comparison with benign breast diseases and control subjects and to know the association between CTC positivity and various clinicopathological parameters, hormonal profile and microRNA polymorphisms. MATERIAL AND METHOD In the present case control study, we included 182 healthy controls, 108 cases of benign breast disease and 114 breast carcinoma cases. Various clinicopathological details of cases were recorded. Immunohistochemistry was performed for estrogen (ER) and progesterone receptors (PR) and Her-2 neu. Circulating tumor cells were analyzed using flow cytometry (EpCAM, CK, CD45). Genotypic frequency of micro RNA polymorphisms was determined by PCR-RFLP assay. RESULTS Circulating tumor cell positivity was observed in 11/114 (9.64%) breast cancer cases but absent in benign and control groups, and was significantly associated with tumor size, histologic type, tumor grade, metastasis and skin infiltration (p < 0.05). Circulating tumor cell positivity did not show any correlation with the immunohistochemical profile. No significant associations between pre-miRNA genetic variations miR-196a2 C/T (rs11614913), miR-146a G/C (rs2910164) and miR-499 T > C (rs3746444) polymorphisms and circulating tumor cell positivity were observed. CONCLUSION The flow cytometry protocol for detection and molecular characterization of circulating tumor cells is a time and cost-effective technique, suitable for routine clinical use. However, more elaborate studies are needed to establish the findings as our study was limited by small sample size.

Abstract
Background A significant development in the breast carcinoma management is the correlation between the presence of hormone receptors in the tumor and response to hormonal therapy and chemotherapy. Human epidermal growth factor receptor-2/neu (Her-2/neu) overexpression also serves as a very useful parameter to predict response to herceptin. Aim of Study The study was conducted to correlate immunohistochemical expression of markers such as estrogen receptor (ER), progesterone receptor (PR), and Her-2/neu with various clinicopathologic parameters. Materials and Methods The study included 509 cases of breast carcinoma over a period of 5 years (from May 2009 to May 2014). Immunohistochemistry (IHC) for ER, PR, and her-2/neu was performed. Results ER positivity was observed in 42.8% (218/509) cases, PR positivity in 31.8% (194/509) cases whereas her-2 neu positivity was seen in 40.7% (203/509) cases. Triple marker (ER, PR, and Her-2/neu) negative cases were 23.6% (120/509) cases. ER and PR expression was found to have a statistically significant correlation with tumor grade. Statistically significant correlation was observed between tumor size and tumor grade and her-2/neu expression. Her-2/neu expression showed statistically significant association with tumor stage. As the tumor grade increased, the proportion of triple-negative cases went on increasing, which was statistically significant. Conclusion IHC has an increasingly important prognostic role in determination of factors that affect clinicopathologic features. Nevertheless, the results of this large series showed different patterns of findings with respect to clinicopathologic features.

Abstract
BACKGROUND Breast cancer is one of the most common malignancies in women and is associated with a variety of risk factors. The functional single-nucleotide polymorphism (SNP) C677T in the gene encoding 5,10-methylenetetrahydrofolate reductase (MTHFR) may lead to decreased enzyme activity and affect the chemosensitivity of tumor cells. This study was designed to investigate the association of MTHFR gene polymorphism (SNP) in the pathogenesis of breast cancer among the North Indian women population. MATERIALS AND METHODS Genotyping was performed by polymerase chain reaction (PCR) using genomic DNA, extracted from the peripheral blood of subjects with (275 cases) or without (275 controls) breast cancer. Restriction fragment length polymorphism was used to study C677T polymorphism in the study groups. RESULTS The distribution of MTHFR (C677T) genotype frequencies, ie, CC, TT, and CT, among the patients was 64.7%, 2.18%, and 33.09%, respectively. In the healthy control group, the CC, TT, and CT frequencies were 78.91%, 1.09%, and 20.1%, respectively. The frequencies of C and T alleles were 81.2% and 18.7%, respectively, in the patient subjects, while they were 88.9% and 11.09%, respectively, among the healthy control group. Frequencies of the CT genotype and the T allele were significantly different (P = 0.007 and P = 0.005, respectively) between the control and the case subjects. CONCLUSION This study shows an association of the CT genotype and the T allele of the MTHFR (C667T) gene with increased genetic risk for breast cancer among Indian women.

Abstract
Aims: Nuclear size increases in malignant tumors and reflects DNA content, ploidy and proliferation index. Present study investigated if the nuclear morphometry could differentiate histomorphologically similar paediatric malignant small round cell tumors on hematoxylin and eosin stained sections for diagnostics in a resource poor setting. Settings and Design: All the consecutive malignant pediatric tumors received in Pathology Department from other faculties of King George's Medical University and also those referred directly to Pathology Department from other hospitals of city/other cities during 3 years period were recorded. Materials and Methods: Morphometric analysis was done in 22 confirmed (by higher ancillary techniques) but histomorphologically difficult to differentiate round cell tumors. All sections were analyzed by cell images from six different areas, using Leica Q win 500 images software. Results: Nuclear measurements were obtained for retinoblastoma (RB) (nine cases), neuroblastoma (five cases), Wilms tumor (WT) (three cases), rhabdomyosarcoma (three cases), malignant hemangiopericytoma (one case) and non-Hodgkin lymphoma (one case). Among the RBs, maximum mean nuclear area percent (24.93) was seen in a case with nerve involvement and metastasis, followed by cases with only nerve involvement (21.60) and smallest area (16.57) was in non-nerve involving, nonmetastatic cases. All five cases of neuroblastoma had almost similar mean nuclear area percent (18.05-18.29). WT case with metastasis had higher nuclear area (21.25) than nonmetastatic (19.47). Amongst all the tumors, minimum value (14.93) was seen in malignant hemangiopericytoma. Conclusion: Morphometric evaluation in paediatric malignant round cell tumors have generated useful data, and needs further multicentric confirmation for implementation.

Abstract
Objective MicroRNAs (miRNAs) are short regulatory RNAs that can modulate gene expression and function as negative regulators. Common genetic variants like single nucleotide polymorphisms (SNPs) in miRNA genes may alter their expression or maturation resulting in varied functional consequences in carcinogenesis. Therefore, we evaluated the genetic variants in pre-miRNAs: hsa-miR-146a G/C (rs2910164), hsa-miR-196a2 C/T (rs11614913), and hsa-miR-499 T>C (rs3746444) for their role in breast cancer susceptibility. Study design The study comprised 121 breast cancer patients, 115 with benign breast disease, and 164 controls. The genotypic frequency of miRNA polymorphisms was determined by PCR-RFLP assay. Logistic regression was used for statistical analysis using SPSS Software version 15.0. In silico analysis was done using various bioinformatics tools (F-SNP, FAST-SNP). Results The heterozygous variant of miR-146a G/C (rs2910164) is associated with the reduced risk of breast cancer at the genotype level as well as at the allele level (p < 0.05, OR = 0.5) as compared to controls. On the contrary, no significant difference was observed in the distribution of miR-196a2 C/T (rs11614913) and miR-499 T>C (rs3746444) polymorphisms in any groups both at genotype and allele levels. On the other hand, in multivariate analysis, we found that the miR-196a2 (rs11614913) C>T was associated with an increased risk of breast cancer risk in postmenopausal females (p = 0.02, OR = 3.2). We also attempted to find out the risk of malignant breast disease in relation to each of the above SNPs on dividing our data on the basis of benign and malignant status, but no significant difference was observed. In silico analysis using F-SNP showed change in transcriptional regulation by miR-146a G/C (rs2910164), miR-196a2 C/T (rs11614913) and miR-499 T>C (rs3746444) variations; the functional score was 0.100, 0.065 and 0.277, respectively. Conclusion The results of the present study demonstrate that miR-146a G/C (rs2910164) polymorphism is associated with reduced genetic susceptibility to breast cancer. However, multivariate analysis showed as miR-196a2 (rs11614913) C>T to be associated with increased risk of breast cancer risk in postmenopausal females. Further multicentric studies involving a large number of cases need to be carried out to strengthen the present results.

Abstract
Mycosis fungoides (MF) is the most common variant of primary cutaneous T-cell lymphoma (CTCL). It is generally associated with an indolent clinical course and characterised by well-defined clinicopathological features. Although rare, CTCLs constitute 65% of all cutaneous lymphoid malignancies, of which 50% are patients with MF. The erythrodermic variants of MF, a malignancy of mature, skin homing and clonal T lymphocytes, usually present in mid to late adulthood. Association with hypereosinophilia is important in prognosis. We report a case of erythrodermic MF with hypereosinophilic syndrome in a 22-year-old female presenting with gradually progressive intractable erythroderma with intensely pruritic multiple papules, plaques, and nodules involving more than 90% of body surface area. Diagnosis was confirmed by histopathological examination and immunophenotyping from multiple skin biopsies.

Abstract
Cutaneous metastases in patients with malignant tumours are an important clue to tumour progression or even the first manifestation of malignancy. Among the various topographic patterns of cutaneous metastasis, the zosteriform pattern of metastasis is rare, and very few cases have been published. Various theories have been proposed for this zosteriform pattern of metastases, but none have been proved. We collected the available PubMed articles on zosteriform skin metastasis from cutaneous melanoma published since 1970 and reviewed the cases, including our own case. Melanoma presents with cutaneous metastasis in up to 44% of patients. Clinicians treating oncology patients should consider zosteriform skin metastasis in the differential diagnosis of zosteriform lesions to avoid inadequate diagnosis and management.

Abstract
Filariasis is prevalent in tropical and subtropical areas and is endemic in regions of India. Lymphatic filariasis in India is caused mainly by two species of nematodes: Wuchereria bancrofti and Brugia malayi, which invade the human lymphatic system. We report two cases of superficial cystic lesions of the upper limb revealed on fine needle aspiration (FNA) to be clinically unsuspected filariasis. Despite similar aetiologies, both cases revealed variations in aspirate nature, smear morphology and peripheral blood findings. FNA provides definitive diagnosis and is an important tool for diagnosing soft tissue swellings owing to filariasis.

Abstract
Objective: Nucleolar organizer region (NOR) associated proteins are argyrophilic and visualized by silver stains. AgNOR pleomorphic dots increase in cancer and most researchers have done a common count of single dots. Pleomorphic dots are few and perhaps indicate a more severe prognosis. The present study was aimed at investigating the relative preponderance and diagnostic value of both pleomorphic and single AgNOR dots in cervical carcinogenesis. Study design: Silver nitrate staining was performed in 50 cervical smears each of cytologically diagnosed normal, inflammatory, low grade squamous intraepithelial lesion (LSIL), High-grade squamous intraepithelial lesion (HSIL), and squamous cell carcinoma cases registered at C.S.M. Medical University, Lucknow, India. Results: The accumulated data revealed a positive and significant correlation of cell counts of both pleomorphic (r = 0.94; p < 0.01) and single dots (r = 0.95; p < 0.01) with disease severity. The rate of increase in cell counts of pleomorphic dots (β = 2.61) was 1.1 times higher than the rate of increase in cell counts of single dots (β = 2.29). Conclusion: This study indicates the diagnostic potential of pleomorphic dots in the process of cervical carcinogenesis. The number of pleomorphic dots also varies significantly in different types of SIL, which may help in discriminating precancerous lesions of the cervix.

Abstract
A 59-year-old woman presented with a history of rapidly progressive recurrent tumor of 6.5 cm diameter of the scalp. Histopathological examination revealed a case of malignant cylindroma. There has been no recurrence or metastases and the patient is disease free at the end of 15 months postoperatively. Malignant transformation occurs less often in solitary form of cylindroma, but once transformed, tumors behave aggressively with extensive local infiltrative growth or metastases. The case is reported to document a rare case of malignant cylindroma arising in a patient with solitary cylindroma on the parieto-temporal region.

Abstract
To emphasize that solitary hydatid cyst can be localized in the soft tissue and present as a soft tissue mass even in an unusual site like face, we report the case of a 42-year-old male patient presenting with a slowly growing mass in right temporal region. Computed tomography (CT) scan showed an encapsulated mass with multiple cysts. Histopathological examination revealed the characteristic findings, which were consistent with soft-tissue hydatid disease. In the absence of visceral organ involvement, this is the first reported case of a primary subcutaneous hydatid cyst in the skin of face in India. In the English literature, only one case of this kind has been reported till date. When imaging methods confirm cystic nature of a swelling, even in unusual sites, one should always keep a possibility of hydatid cyst and manage accordingly during surgery to avoid precipitation of acute anaphylaxis.

Abstract
The KIT gene is a receptor tyrosine kinase class III expressed by early hematopoietic progenitor cells and plays a significant role in hematopoietic stem cell proliferation, differentiation and survival which is considered to be a remarkable feature in the course of growth of acute myeloid leukaemia (AML). Owing to insufficient study of mutations in the KIT gene, the diagnosis and rate of recurrence of these mutations with divergent subtypes in AML cases in India is of concern. In order to find out the frequency of mutations of KIT gene exon 8 in 109 AML cases, we have performed polymerase chain reaction-single-strand conformation polymorphism (PCR-SSCP) followed by DNA sequencing and have identified 24 mutations in exon 8 in 13 cases, including deletions at codon 418 (n = 3), 419 (n = 11) and 420 (n = 5) as well as point mutations at codon 417 (n = 1) and 421 (n = 4). In eleven AML cases, exon 8 deletion and point mutations involved the loss at codon Asp419 immoderately conserved cross species placed in the receptor extracellular domain. Frequency elevation of the KIT proto-oncogene exon 8 deletion and point mutations in AML cases allude a crucial function for this region of the receptor extracellular domain. Thus, we report the incidence of acquired mutations in exon 8, with consistent loss at codon Asp419, in 10.09 % of AML cases in a selected Indian population.

Abstract
BACKGROUND Fine needle aspiration (FNA) is a quick, minimally invasive procedure for evaluation of breast tumors. The Scarff-Bloom-Richardson (SBR) grade on histological sections is a well-established tool to guide selection of adjuvant systemic therapy. Grade evaluation is possible on cytology smears to avoid and minimize the morbidity associated with overtreatment of lower grade tumors. AIM The aim was to test the hypothesis whether breast FNA from the peripheral portion of the lesion is representative of Scarff-Bloom-Richardson grade on histopathology as compared to FNA from the central portion. MATERIALS AND METHODS Fine-needle aspirates and subsequent tissue specimens from 45 women with ductal carcinoma (not otherwise specified) were studied. FNAs were performed under ultrasound guidance from the central as well as the peripheral third of the lesion for each case avoiding areas of necrosis/calcification. The SBR grading was compared on alcohol fixed aspirates and tissue sections for each case. RESULTS Comparative analysis of SBR grade on aspirates from the peripheral portion and histopathology by the Pearson chi-square test (χ(2) =78.00) showed that it was statistically significant (P<0.001) with 93% concordance. Lower mitotic score on aspirates from the peripheral portion was observed in only 4 out of 45 (9%) cases. The results of the Pearson chi-square test (χ(2) = 75.824) with statistically significant (P=0.000). CONCLUSION This prospective study shows that FNA smears from the peripheral portion of the lesion are representative of the grading performed on the corresponding histopathological sections. It is possible to score and grade by SBR system on FNA smears.

Abstract
Extramedullary hematopoeisis (EMH) occurs when function of the bone marrow is insufficient or destroyed. We report a case of lymph nodal mass in a young patient, diagnosed on fine needle aspiration cytology (FNAC) as infiltration by leukemia along with features of EMH. FNA smears from axillary lymph node revealed lymphoblasts with hand mirror cell and teat cell morphology. Also seen were occasional megakaryocytes and metamyelocytes.

Abstract
AIM To delineate and characterize the cytomorphologic features of pilomatrixoma (PMX) helpful in correct diagnosis of the lesion on fine needle aspiration cytology (FNAC). MATERIALS AND METHODS Archival records of clinical findings, FNAC and histopathological reports of PMX cases were analyzed. Aspirate findings in 14 cases of PMX were correlated with detailed clinical data and subsequent histopathology on excisional biopsy. Different morphological findings were graded semiquantitatively from 0 to 3+. RESULTS The series showed female preponderance, with head and neck being the commonest site. Majority patients had a single tumor with mean size of 1.6 cm. Out of 14 biopsy proven cases of PMX, cytology findings revealed PMX in 7 cases on the basis of ghost cells, groups of basaloid cells, squamous cells in combination with multinucleated giant cells and calcium deposits in a background of debris. The main reasons for erroneous diagnosis were predominance of one component over the others and non-representative aspirated material. CONCLUSIONS The cytological features of PMX are characteristic and allow a conclusive diagnosis provided the smears are examined keenly bearing in mind the diagnostic traps that can mislead a cytopathologist.

Abstract
Background: Cytological examination of effusion fluid is a relatively easy and quick method for the diagnosis of primary or secondary malignancy. Aims: To analyze the cytological significance of cell cannibalism in malignant effusion samples. Materials and Methods: A retrospective review of 100 cases of malignant effusion was done. These 100 cases included 50 cases of contiguous, local spread to pleural/ascitic fluid. The remaining 50 cases were of disseminated malignancy. Effusions due to hematolymphoid malignancies were excluded. Smears from these cases were assessed for the presence of cell cannibalism, tumor cell within a tumor cell. Results: The cannibalistic cells were more common in effusions with disseminated malignancy (nine out of 50 cases i.e. 18%) compared with cases of contiguous, local spread (two out of 50 cases i.e. 4%). Chi square test showed this difference to be statistically significant (x2 5.005, P=0.025). The majority of the cases were of carcinoma lung (6/11). Cytomorphologically, histiocytes displaying phagocytosis can simulate tumor cells and need to be distinguished. Conclusions: Presence of cell cannibalism in malignant effusions is more often an indicator of disseminated malignancy with secondaries and higher tumor stage. Furthermore, cannibalism may provide a reliable predictor of progression of tumor from primary to the metastatic site.

Abstract
A 45-year-old male presented with a 6 month history of an enlarging smooth, erythematous plaque over the central part of his face. Mild erythema of both eyes was present. Sarcoidosis, Hansen disease, lupus vulgaris, cutaneous leishmaniasis, pseudolymphoma, foreign body granuloma, granuloma faciale, discoid lupus erythematosus, and granulomatous rosacea were considered in the differential diagnosis. CBC, urinalysis, renal function tests, liver function tests, serum electrolytes, and blood sugar were all normal. Chest X-ray and ECG revealed no abnormality. Serology for syphilis and HIV, and mantoux test were negative. Slit-skin smear, tissue smear and culture for AFB and fungi were negative. Skin biopsy revealed multiple non-caseating epitheloid granulomas around the pilosebaceous unit suggestive of granulomatous rosacea. Granulomatous rosacea, a rare entity comprising only about 10 percent of cases of rosacea can mimic many granulomatous conditions both clinically and histologically making the diagnosis an enigma. It usually presents as yellowish brown-red discrete papules on the face; non-caseating epithelioid granulomas are seen on histology examination. We herein report the case because it presented in atypical fashion, as a solitary indurated plaque on the nose, likely representing Morbihan's disease or solid persistent facial edema of rosacea (rosacea lymphedema).

Abstract
To evaluate the expression of HER-2/neu in various ovarian lesions, 75 cases of ovarian tissues (25 cases of benign lesions and 50 cases of carcinoma) were studied in the department of pathology, Pt. B.D. Sharma PGIMS, Rohtak. Besides conventional H&E staining, representative sections were processed for immunohistochemical staining for HER-2/neu detection. Two (8%) of benign cases were 1+ positive and 19 (38.0%) of malignant lesions were positive for HER-2/neu staining with intensity 1+/2+ in 16 cases (32.0%), 3+ in 2 cases (4%) and 4+ in 1 case (2%). It was observed that HER-2/neu expression was significantly associated with high grade ovarian tumours, however intensity of positivity did not correlate with the grade of tumour.
