Abstract
Manas Kumar BeheraBackground and Aims Gastric cancer is the third most common cause of cancer-related mortality worldwide after lungs and colorectum. Although controversial, Her2neu overexpression by immunohistochemistry is usually associated with poor prognosis in patients with carcinoma stomach. We conducted a prospective study to evaluate the prognostic role of Her2neu and its correlation with clinical, pathologic type, and stage of the disease. Methods A prospective study was performed on paraffin blocks of 111 gastric cancer specimens (88 patients were biopsy specimens and 23 were gastrectomy specimens). The paraffin blocks were processed for Her2neu receptor immunohistochemical staining and fluorescence in situ hybridization, and scoring was done. Results Her2neu overexpression was detected in 30 out of 111 (27%) patients. The mean age was 57.68 ± 12.82 years, with males constituting two-thirds of total patients. Tobacco addiction was found in 44% of the patients and smoking in 33% of the patients. Her2neu expression was similar in Lauren's intestinal and diffuse histologic type; however, proximal gastric tumors overexpressed Her2neu as compared with distal tumors. Her2neu 2+ or 3 + (odds ratio: 2.52, 95% CI: 1.61-3.95, p = 0.001) was the only independent predictor of survival in gastric cancer patients. Kaplan-Meir survival analysis showed that the survival of gastric cancer patients with Her2neu overexpression (Her2neu 2+ or 3 + ) was significantly lower than that of those with Her2neu nonexpression ( p = 0.001). Conclusion Her2neu positivity was a significant predictor of mortality in patients with carcinoma stomach, and Her2neu overexpression was associated with a lower overall survival rate compared with Her2neu nonexpression.

Abstract
BACKGROUND Subcutaneous insulin therapy is associated with important injection site complications, which can influence insulin pharmacokinetics resulting in glycemic fluctuations above and below target levels for blood glucose. OBJECTIVE Our objective was to assess the prevalence and risk factors of cutaneous complications including insulin derived amyloidosis in insulin-injecting diabetes patients and to study the role of ultrasonography (in comparison to gel-assisted palpation) in early diagnosis of lipohypertrophy (LH). METHODS This was a cross-sectional study conducted at a tertiary care center in India, wherein 500 patients injecting insulin for ≥2 years were randomly enrolled and evaluated for the presence of cutaneous complications of insulin therapy through clinical examination, ultrasonography and punch biopsy of skin. RESULTS Clinical examination detected LH in 44.6% of patients. Ultrasonography diagnosed additional 13.4% of patients with LH which were missed on clinical examination. Incorrect rotation of sites (P < 0.001) and insulin syringe reusage for more than five times (P < 0.001) significantly increased the risk of LH. Skin biopsy was performed in 100 cases, out of which two patients showed apple green birefringence and its association with insulin was confirmed by positive staining with anti insulin antibody in these two patients. CONCLUSION Improper rotation of sites and reuse of needles were the leading causes of LH in Indian diabetic patients. Ultrasonography is more objective and reliable method of detecting LH. Insulin-derived amyloidosis may be a more common complication of insulin therapy than previously thought.

Abstract
Epithelial-myoepithelial carcinoma (EMC) is a biphasic low-grade malignant tumor that shows ductal structures lined by the ductal cells with surrounding myoepithelial cells. EMC is most commonly reported in the parotid gland followed by other major and minor salivary glands. EMC of the tongue is an extremely uncommon tumor, with only five previously published case reports. We herein report the sixth case of EMC of the tongue. A 40-year-old female who had throat pain, dysphagia, and right earache for 3 years showed a 4 cm × 4 cm nodular tumor at the base of her tongue. Histopathological and immunohistochemical features were diagnostic of EMC with cervical lymph node metastasis. The metastatic behavior of EMC of the tongue in the absence of myoepithelial anaplasia or high-grade histological features is unusual and reported in this case report for the first time.

Abstract
BACKGROUND Ovarian tumors are one of the leading cancers in females with variable pathological types. This study describes the distribution, clinical and pathological details of various histopathological types of ovarian tumors in a tertiary care hospital in North India. MATERIALS AND METHODS A retrospective data of 3 years were collected for ovarian tumors submitted to the pathology department of a tertiary care hospital. Data were classified according to the latest World Health Organization (WHO) Classification into epithelial tumors, germ cell tumors, sex cord-stromal tumors, and others. RESULTS A total of 212 cases of ovarian tumors were studied, 186 were unilateral and 26 were bilateral. Resection specimen, part of specimen, and block review formed 80.2%, 15.1%, 4.7%, respectively. Epithelial tumors formed the majority in 71.7% of cases followed by germ cell tumors (22.2%), sex cord-stromal tumors (3.8%) and others (2.3%). Maximum number of cases in the respective groups occurred in the age groups 31-40, 21-30, 51-60, and 41-50 years, respectively. Overall, benign tumors were 63.7%, malignant tumors were 31.1%, and borderline were 5.2%. The most common histopathological type of benign and malignant tumor was benign serous cystadenoma (18.8%) and serous carcinoma (9.9%), respectively. CONCLUSION In the present study, ovarian tumors were classified according to the WHO classification, epithelial and germ cell tumors were the major types of ovarian tumors. Benign epithelial tumor formed the majority with 46.2% cases. Serous cystadenoma and mature cystic teratoma were the predominant type of epithelial and germ cell tumors, respectively.

Abstract
INTRODUCTION After the recent approval of Trastuzumab (anti-HER2 antibody) for the treatment of HER2 overexpressed Gastric Adenocarcinoma (GA), importance of HER2 testing is increasingly recognized. However, there is paucity of studies for HER2 overexpression in the Indian patients of GA. Similarly, study of p53 expression in the Indian patients of GA is infrequent. AIM To study immunohistochemical expression of HER2 and p53 in GA biopsy samples. MATERIALS AND METHODS This was a cross-sectional observational study. The expression of HER2 and p53 by immunohistochemistry were analyzed in 50 cases of GA. The HER2 expression was scored as negative (0 and 1+), equivocal (2+), and overexpression (3+). The p53 expression was quantified as negative (0-9% tumour cells) and positive (≥10% tumour cells). The intensity of p53 expression was assessed as strong and weak. RESULTS Mean age of the patients was 56.8±14.8 years. Male:female ratio was 2:1. Histological types of adenocarcinoma were intestinal (68%), diffuse (28%), and indeterminate (4%). HER2 overexpression and equivocal results were present in 10% cases, each. Overall, a positive expression of p53 was seen in 72% (strong and weak intensities: 66.7% and 33.3% cases, respectively). CONCLUSION As compared to HER2 overexpression, a higher incidence of p53 expression was seen (10% vs.72%) in GA.

Abstract
Male breast cancers constitute less than 1% of all the breast cancers. Papillary carcinoma is a very rare tumour of the male breast. Due to rarity, Fine Needle Aspiration Biopsy (FNAB) findings of papillary carcinoma in male breast are seldom reported. A 55-year-old male presented with a lump in the left breast of two years' duration. FNAB was reported as fibroadenoma. Histopathological examination of the excised breast lump revealed invasive papillary carcinoma. Immunohistochemistry showed expression of pancytokeratin, oestrogen receptor, and progesterone receptor. Negative immunostaining was seen for HER2, p53, 34βE12, and CD34. Ki-67 proliferative index was 5%. We have discussed cytological findings of invasive papillary carcinoma and its differential diagnoses. Cytopathologists must be aware of cytologic findings of invasive papillary carcinoma of the male breast.

Abstract
The conventional methods for diagnosis of tubercular lymphadenitis (TBLN) such as - fine needle aspiration cytology, Ziehl-Neelsen staining and culture have limitations of low sensitivity and/or specificity. So, it becomes essential to develop a rapid, sensitive, and specific method for an early diagnosis of TBLN. Therefore, the present study was conducted to evaluate nested multiplex polymerase chain reaction (nMPCR) targeting MTP40 and IS6110 gene sequences of Mycobacterium tuberculosis and Mycobacterium tuberculosis complex, respectively in 48 successive patients of TBLN and 20 random patients with non-tubercular lymph node lesions. Out of the 48 cases of TBLN, 14 (29.2%) were found to be positive by Ziehl-Neelsen staining, 15 (31.2%) were positive by culture and 43 (89.6%) cases were positive after first round of PCR while 48 (100%) cases were positive by nMPCR assay. The sensitivity and specificity of nMPCR was found to be 100% for the diagnosis of TBLN. The results thus obtained indicate that nMPCR assay is a highly sensitive and specific tool for the diagnosis of TBLN.

Abstract
Aims: To devise nested multiplex polymerase chain reaction (NMPCR) protocol for detection of mucosal human papilloma viruses (HPVs) and typing of HPV-16 and -18 in formalin-fixed, paraffin-embedded (FFPE) tissues of carcinoma cervix (CaCx). Settings and Design: Cross-sectional observational study. Materials and Methods: NMPCR was done for simultaneous detection of HPV, targeting 134 bp L1 capsid gene employing GP+/mGP+ primers and typing of genotypes-16 and -18, targeting E6/E7 gene from 34 FFPE tissue blocks of CaCx and cervical intraepithelial neoplasia (CIN). Detection of 142 bp consensus sequence of L1 capsid gene was performed by nested PCR employing MY/GP+ primers. Sequencing of selected PCR amplicons of the later protocol obtained from control cell line DNA and 5 select samples were done for validation of the NMPCR protocol. Statistical Analysis Used: Calculation of percentage from the Microsoft Excel Software. Results: Of 26 FFPE samples of CaCx, 17 (65.3%) samples were found positive for HPV by NMPCR. Amplicons of 142 bp L1 capsid gene employing MY/GP+ primers were observed in 11 (42.3%) samples of CaCx. Nearly 25% samples of CIN were positive for HPV. On sequence analysis, it was observed that the sample typed as HPV-16 by NMPCR was found to be the same on sequencing of amplicons obtained after MY/GP+ nested PCR. Conclusions: This study indicates the usefulness of our NMPCR protocol for detection of mucosal HPVs and typing of HPV-16 and -18 from FFPE tissue samples of CaCx. The NMPCR protocol may be used to detect HPV and type common genotypes-16 and -18 in fresh tissue of cervical biopsy or scrape samples for screening of CaCx.

Abstract
INTRODUCTION PAX5 is an immunomarker of B-cell origin and useful in the diagnosis of lymphoma. There is hardly any study on PAX5 expression in Indian patients with lymphoma. AIM To evaluate the diagnostic utility of PAX5 as an adjunct immunohistochemical marker in the diagnosis of Hodgkin Lymphoma (HL) and Non-Hodgkin Lymphoma (NHL). MATERIALS AND METHODS Immunohistochemistry was performed against CD20, CD3, CD15, CD30, and PAX5 on formalin fixed paraffin embedded tissue of 71 cases of lymphoma and CD20, CD3 and PAX5 in control samples of reactive lymph nodes. Frequency, mean values, and percentage were calculated. Fisher's-exact test and test for analysis of variance were applied. RESULT For 24 cases of HL and 47 cases of NHL, the mean age of patients was 17.6±14.8 years and 44.1±21.6 years, respectively. The male: female ratio for both HL and NHL were 1.7:1. Among NHL cases, the numbers of B-cell and T-cell types were 39/47 (83%) and 8/47 (17%), respectively. In comparison to control samples, PAX5+ expression was seen in 23/24 (95.8%) cases of HL (p=1.000) and 32/39 (82%) cases of B-NHL (p=0.0834). All the cases of T-NHL showed negative expression of PAX5 (p<0.0001). Analysis of variance between NHL, HL and control samples was statistically significant (p<0.0001). CONCLUSION PAX5 staining between control samples and cases of classical HL and B-NHL was statistically not significant, whereas, statistically significant difference was observed with T-NHL. Thus, PAX5 may be used as an adjunct marker in the diagnosis of classical HL and B-NHL.

Abstract
Intraosseous hemangiomas are one of the rarest lesion of jaw bones (0.5-1%) occurring most commonly in vertebral column, skull bone, and rarely in mandible. Mainly occurs in the second decade of life with female: male predilection (2:1). Origin of hemangiomas is still debatable. World Health Organization considers it as a true benign neoplasm of vascular origin, and many authors believe it to be a hamartoma. It is very difficult to diagnose due to variable clinical and radiological features. A biopsy is not done on a routine basis due to a higher risk of hemorrhage. Management is very difficult because of massive vascular network in that region. Here, we are presenting a case report of a 14-year-old boy with intraosseous hemangioma of right body of mandible, which was treated with en bloc surgical resection of mandible and followed by reconstruction.

Her barium X-ray showed absence of the duodenal bulb and the C-loop. Her endoscopy showed deformed stomach with multiple ulcers and diverticuli. The gastric outlet was not visualized. Distal gastrectomy with gastro-duodenal anastomosis was performed. Histopathological findings revealed transmural dense infiltrates of eosinophils, consistent with eosinophilic gastritis.

Abstract
Neoplastic lesions of the fallopian tube are rarely seen by surgical pathologists. Haemangioma of the fallopian tube is an extremely rare benign neoplasm. A 30-year-old lady with polymenorrhea and dysmenorrhea underwent hysterectomy and bilateral salpingo-oophorectomy. Her left fallopian tube showed a 2mm sized solid nodule in the wall. Histopathological examination revealed a well-defined vascular lesion in the left fallopian tube, consistent with capillary haemangioma. The vascular endothelium was highlighted by CD34 immunostaining. Our literature review has identified 10 cases of cavernous haemangioma of the fallopian tube. To the best of our knowledge, we report the first ever case of capillary haemangioma of the fallopian tube. This is also the smallest detected haemangioma in the fallopian tube.

Abstract
The aim of this study was to develop multi-walled carbon nanotubes (MWCNT) which were covalently conjugated with transferrin by carbodiimide chemistry and loaded with docetaxel as a model drug for effective treatment of lung cancer in comparison with the commercial docetaxel injection (Docel™). d-Alpha-tocopheryl polyethylene glycol 1000 succinate (TPGS) was used as amphiphilic surfactant to improve the aqueous dispersity and biocompatibility of MWCNT. Human lung cancer cells (A549 cells) were employed as an in-vitro model to access cellular uptake, cytotoxicity, cellular apoptosis, cell cycle analysis, and reactive oxygen species (ROS) of the docetaxel/coumarin-6 loaded MWCNT. The cellular uptake results of transferrin conjugated MWCNT showed higher efficiency in comparison with free C6. The IC50 values demonstrated that the transferrin conjugated MWCNT could be 136-fold more efficient than Docel™ after 24h treatment with the A549 cells. Flow cytometry analysis confirmed that cancerous cells appeared significantly (P<0.05) in the sub-G1 phase for transferrin conjugated MWCNT in comparison with Docel™. Results of transferrin conjugated MWCNT have showed better efficacy with safety than Docel™.

Abstract
Langerhans cell histiocytosis (LCH) is a rare clonal disorder of unknown etiology and characterized by the proliferation of dendritic cells. LCH most commonly involves the bone followed by the skin and the lymph nodes. Recently, only a few cases of LCH with predominant lymph node involvement have been diagnosed by fine-needle aspiration cytology (FNAC). A 2-year-old boy presented with generalized lymphadenopathy, fever, and cough. The patient had hepatosplenomegaly, anemia, and lytic lesions in the skull. FNAC from the largest submandibular lymph node showed features of LCH. The large cells of LCH showed positive immunostaining for S-100 protein on FNAC smears. Later, lymph node biopsy and immunohistochemistry against S-100 protein and CD1a confirmed the diagnosis of LCH. The patient was treated with chemotherapy and he is under regular follow-up. This case report highlights the importance of FNAC as a rapid and accurate investigation in the diagnosis of lymph node predominant LCH.

Abstract
AIM The present study was aimed to assess the contractile status of neonatal small intestinal smooth muscle of dilated pre-atretic part of intestinal atresia to resolve debatable issues related to mechanisms of persistent dysmotility after surgical repair. MATERIALS AND METHODS A total of 34 longitudinally sectioned strips were prepared from pre-atretic dilated part of freshly excised 8 jejunal atresia type III a cases. Spontaneous as well as acetylcholine- and histamine-induced contractions were recorded in vitro by using organ bath preparations. Chemically evoked contractions were further evaluated after application of atropine (muscarinic blocker), pheniramine (H1 blocker), and lignocaine (neuronal blocker) to ascertain receptors and neuronal involvement. Histological examinations of strips were made by using Masson trichrome stain to assess the fibrotic changes. RESULTS All 34 strips, except four showed spontaneous contractions with mean frequency and amplitude of 5.49 ± 0.26/min and 24.41 ± 5.26 g/g wet tissue respectively. The response to ACh was nearly twice as compared to histamine for equimolar concentrations (100 μM). ACh (100 μM) induced contractions were attenuated (by 60%) by atropine. Histamine (100 μM)-induced contractions was blocked by pheniramine (0.32 μM) and lignocaine (4 μM) by 74% and 78%, respectively. Histopathological examination showed varying degree of fibrotic changes in muscle layers. CONCLUSIONS Pre-atretic dilated part of jejunal atresia retains functional activity but with definitive histopathologic abnormalities. It is suggested that excision of a length of pre-atretic part and early stimulation of peristalsis by locally acting cholinomimetic or H1 agonist may help in reducing postoperative motility problems in atresia patients.

Abstract
Paraganglioma of the urinary bladder is a rare tumour derived from chromaffin tissue of the sympathetic nervous system. Paraganglioma of the urinary bladder especially the non-functional type is often misdiagnosed as urothelial cancer. Two female patients aged 32 years and 45 years presented with painless haematuria without any symptoms of catecholamine excess. Radiological investigations revealed urinary bladder tumour. The tumour was removed by transurethral resection in both the patients. Histopathological diagnosis was paraganglioma, which was confirmed by immunohistochemistry. Complete resection of tumour by transurethral approach is curative in paraganglioma of the urinary bladder. We hereby, also discuss the salient features of nonfunctional paraganglioma of the urinary bladder.

Abstract
Prostatic adenocarcinoma (PA) is a common visceral malignancy of elderly men. Cutaneous metastasis of PA is rare. The incidence is <1%. A 55-year-old man presented with urinary symptoms and multiple cutaneous nodules around suprapubic region, inner aspect of both thighs and scrotum. Fine-needle aspiration cytology (FNAC) of cutaneous nodules was suggestive of metastatic adenocarcinoma. Skin and prostatic biopsies confirmed the cytological diagnosis. Serum level of prostate specific antigen was raised. Total prostatectomy revealed adenocarcinoma of Gleason's score 7 (3 + 4). Though rare, cutaneous metastases of PA must be known to cytopathologists. Meticulously performed FNAC in such cases may help in early diagnosis.

Abstract
Thrombocytosis is defined as a platelet count greater than 400×10(9)/L. Electric shock may lead to tissue injury and marked thrombocytosis. We herein report a case of 45-year-old woman, who was hospitalized with progressively increasing weakness, tingling sensation, and numbness of the bilateral lower limbs. She had a history of receiving electric shock during household work, 15 days prior to her admission. Her laboratory investigations revealed a markedly increased platelet count (1,570×10(9)/L) along with increased level of serum uric acid (12 mg/dL), and mild increase in serum potassium (6.7 mmol/L), and serum alanine transaminase (50 U/L). She was treated with intravenous fluids, calcium, and multivitamins. Following hospitalization and treatment, condition of the patient improved, her symptoms resolved, and her platelet counts declined. We report this case because of rare presentation of marked thrombocytosis secondary to electric shock with a brief discussion on pathophysiology of this condition.

Abstract
The present study was undertaken to determine whether acute respiratory distress syndrome (ARDS) is produced after Mesobuthus tamulus (MBT) envenomation and compared it with oleic acid (OA)-induced ARDS. The trachea, jugular vein and femoral artery were cannulated in anesthetized adult rats. Lethal dose of MBT venom (5 mg/kg) or OA (75 μL) was administered intravenously and the time-dependent changes in respiratory frequency (RF), heart rate (HR) and mean arterial pressure (MAP) were recorded. Minute ventilation (MV) and the PaO2/FiO2 (P/F) ratio were also determined. At the end lungs were excised, one lung was used for histopathological examination and the other was used for determination of pulmonary water content physically. MBT venom or OA produced hypoxemia, pulmonary pathology (alveolar damage, infiltration of inflammatory cells, capillary damage and exudation) and pulmonary edema implicating for ARDS. However, the hypoxemia in MBT venom group was associated with decreased MV, apnea/bradypnea, and bradycardia whereas, in OA group it was seen with increased MV, tachypnea, and tachycardia. Lack of effect of hypoxemic drive on RF/MV or HR in MBT venom group unlike OA group, suggests the involvement of medullary centers. The present results demonstrate that MBT venom produces ARDS. However MBT venom-induced ARDS involves pulmonary as well as extrapulmonary mechanisms.

Abstract
Primary breast lymphoma (PBL) is a rare entity. It represents 0.4% of malignant breast lesions and 2% of extranodal lymphomas. A 23-year-old woman presented with a left breast lump followed by palpable left axillary lymphadenopathy. Fine-needle aspiration cytology (FNAC) and histopathology were diagnostic of non-Hodgkin lymphoma-large cell type. Immunohistochemistry was positive against leukocyte common antigen and CD20. Because PBLs are uncommon malignant lesions and they usually do not have characteristic clinical and imaging findings, FNAC may prove to be a simple, rapid, reliable, and cost-effective procedure for successful diagnosis of the PBL.

Abstract
PURPOSE Congenital pouch colon (CPC) associated with anorectal malformation (ARM) is most commonly reported from Northern India. So far, no physiologic study comparing the detailed contractile status of CPC with non-CPC conditions are available. The present article deals with the contractile study and histopathologic observations in CPC, which may be useful for better surgical management. METHODS Freshly excised 12 neonatal CPC and similar number of non-CPC (control) specimens were transferred to ice-cold (4 degrees C-6 degrees C) Krebs-Ringer solution bubbled with 100% oxygen. Longitudinally prepared 2 to 4 colonic strips were obtained from central part of each specimen and subjected to the contraction recording after exposure to cumulative concentrations of acetylcholine (ACh) and histamine. Acetylcholine-induced contractions were evaluated after application of atropine (muscarinic blocker), and histaminergic contractions were recorded after pheniramine (H(1) blocker), lignocaine (neuronal blocker), and atropine. Histopathologic observations were made by using H&E and Masson trichrome stains. RESULTS Control specimens showed spontaneous contractions, but CPC strips did not. Both control and CPC responded to ACh and histamine. The response to histamine was greater (P < .05) in CPC as compared to control, whereas the response to ACh was more (P < .05) in control. In CPC, response of histamine (100 micromol/L) was blocked by pheniramine (0.32 mmol/L) and lignocaine (4 mmol/L) by 97% and 80%, respectively, and enhanced by 57% after preapplication of atropine (10 micromol/L). Acetylcholine (100 micromol/L)-induced contractions were attenuated (86%) in presence of atropine. Histopathologic examination showed fewer mature ganglion cells with various changes in muscle layers including fibrosis, disruption, hypertrophy, atrophy, and constriction bands. CONCLUSION Congenital pouch colon associated with ARM lacks normal spontaneous contractions but retains ACh and histamine-induced contractility. In view of the functional and histologic abnormalities, we propose that CPC associated with ARM is an abnormally functional and developed tissue. Therefore, resection of the pouch should be considered for better functional outcome of the remaining bowel.

Abstract
The distribution of hemoglobin E (alpha2beta2 26Glu (R)Lys ) is mostly restricted to Northeastern India. While evaluating the patients of jaundice, we came across two cases of hemoglobin E (Hb E) disorders. The first case is in a 22-year-old Bengali male and the second case of Hb E/beta thalassemia in a 5-year-old Hindu boy. The family study revealed Hb E trait in both the parents of Case 1, whereas in Case 2, the father was found to have Hb E trait and the mother had beta -thalassemia minor, thus confirming the diagnosis. Herein, we present the laboratory diagnosis and comparative data of the spectrum of Hb E disorders (i.e., heterozygous Hb E trait, homozygous Hb E disease and compound heterozygous Hb E/beta -thalassemia) that was found in our index cases and their parents.
