Abstract
46 XX ovotesticular DSD is a rare disorder. It presents with cryptorchidism, hypospadias or ambiguous genitalia at birth, gynaecomastia in adolescent stage or infertility in adult age. We report here a 20 year old phenotypically male who presented with gynaecomastia and found to have testis on right side and left inguinoscrotal swelling consisting of ovary, uterus and fallopian tubes. Evaluation revealed SRY negative 46 XX karyotype. He underwent surgical removal of ovary and mullerian structures. The highlight of case is development of testicular tissue in absence of SRY gene.

Abstract
Amyloidosis is a group of disease that is characterized by the deposition of extracellular abnormal proteinaceous material (amyloid), in various organs. Amyloidosis involving the liver is common and the radiological findings are often nonspecific. We present the case of a 40-year-old female who presented with abdominal pain. Ultrasound abdomen was reported as massive hepatomegaly with diffuse liver parenchymal disease. Bone marrow aspiration showed normomegaloblastic erythroid hyperplasia and plasma cells were within normal limits (5%). Also, amorphous, eosinophilic fragmented to smudgy material within the interstitium of cell trails was seen. Bone marrow biopsy and liver biopsy also showed similar kind of homogenous eosinophilic material. Both liver biopsy and bone marrow biopsy were subjected to special stains which confirmed the presence of amyloid. The patient did not have clinical or laboratory findings suggestive of any other organ involvement. Thus, we conclude that clinical and imaging presentations of amyloidosis are often nonspecific, hence biopsy is always required to confirm the diagnosis. Amyloid deposits on bone marrow aspiration are a rare occurrence and are often missed. It is an unusual sighting with very few studies mentioning its occurrence.

Abstract
Avascular necrosis of the femur head (AVNFH) is a debilitating disease caused due to the use of alcohol, steroids, following trauma or unclear (idiopathic) etiology, affecting mostly the middle aged population. Clinically AVNFH is associated with impaired blood supply to the femoral head resulting in bone necrosis and collapse. Although Homocysteine (HC) has been implicated in AVNFH, levels of homocysteine and its associated pathway metabolites have not been characterized. We demonstrate elevated levels of homocysteine and concomitantly reduced levels of vitamins B6 and B12, in plasma of AVNFH patients. AVNFH patients also had elevated blood levels of sodium and creatinine, and reduced levels of random glucose and haemoglobin. Biophysical and ultrastructural analysis of AVNFH bone revealed increased remodelling and reduced bone mineral density portrayed by increased carbonate to phosphate ratio and decreased Phosphate to amide ratio together with disrupted trabeculae, loss of osteocytes, presence of calcified marrow, and elevated expression of osteocalcin in the osteoblasts localized in necrotic regions. Taken together, our studies for the first time characterize the metabolomic, pathophysiological and morphometric changes associated with AVNFH providing insights for development of new markers and therapeutic strategies for this debilitating disorder.

Abstract
A parathyroid adenoma present in an ectopic site, in the anterior mediastinum, is a rare cause of persistent hyperparathyroidism. Though its occurrence in the mediastinum is unusual, existence has been noted in literature for more than a century. We describe a case of a 35-year-old male presenting with complaints of pain abdomen, clinically diagnosed as acute necrotizing pancreatitis, with raised serum calcium. Patient received symptomatic treatment for the pancreatitis which subsided. However, high levels of serum calcium persisted. Suspecting hyperparathyroidism, ultrasound neck was done, revealing apical thoracic mass. CT scan of neck revealed a large heterogeneous enhancing mass in superior mediastinum. Fine Needle Aspiration (FNA) of the mass done endoscopically was confusing as it showed features suggestive of a cystic teratoma. However, persistently raised calcium levels along with raised parathormone warranted a Technetium - 99 (Tc-99m) sestamibi scan which revealed positive uptake involving right inferior parathyroid extending to superior mediastinum. The mass was surgically excised and it was diagnosed as a parathyroid adenoma. This case helps bring to light the necessity to consider ectopic parathyroid adenoma as an important differential diagnosis in mediastinal tumour with persistent hypercalcaemia, and as a cause of hyperparathyroidism.

Abstract
Spindle cell lesions of the head and neck region are diverse in nature by means of clinical and biological heterogeneity. Though few lesions are found to be malignant, several others are benign or merely reactive in nature. Although these lesions are fairly common occurring in other parts of the body, they are very rare in the oral cavity, accounting for less than 1% of all tumours in the oral region. Herein, a case of 48-year-old man who presented with a polypoid lesion of the maxilla has been reported. Histopathological examination and immunohistochemistry revealed spindle cell sarcoma of the left maxillary sinus. We present this rare tumour to contribute to the better understanding and awareness of this rare malignancy where diagnosis can be very challenging.

Abstract
INTRODUCTION Mutation in p53 gene and accumulation of p53 protein is a common genetic event in colorectal carcinomas. p53 mutation can be detected by various techniques such as DNA sequencing, polymerase chain reaction and immunohistochemistry (IHC). However, IHC is simple and is consistent with other techniques. AIM To establish a correlation between overexpression of p53 with the clinical features, tumour histopathology and stage of Colorectal Carcinoma (CRC). MATERIALS AND METHODS This prospective and retrospective study of clinical, histopathological and IHC features of CRC was conducted on colectomy and abdomino-perineal resection specimens received from January 2008 to June 2013. For each case, the clinical features, tumour morphology and p53 status (by IHC) were evaluated. RESULTS The most common histologic type of CRC was Non-Specific Type (NST) and grade II tumours were seen predominantly (60%). Overall, 67.5% of CRCs showed p53 positivity on IHC. Intense p53 positivity was observed in 37.5% of CRCs of NST type and 33.3% of mucinous adenocarcinomas showed moderate positivity. Grade III tumours showed variable p53 positivity and those with lymph node metastasis showed moderate (55.6%) or intense positivity (53.8%). But there was no statistically significant correlation of p53 status and various clinicopathological prognostic factors. CONCLUSION As p53 protein overexpression is seen in a relatively high percentage of CRCs, it seems that p53 mutation plays an important role in development of CRC. However, no direct correlation could be established between p53 results and the patients' age, sex, tumour site, size, histological type, grade, lymph node status, or TNM stage. A prolonged follow up is necessary to conclude whether p53 status has any influence on the long, term prognosis and patient survival.

Abstract
BACKGROUND Oral cancer is the sixth most common malignancy in the world. Viruses are the causative agents of approximately 10-15% of all cancers worldwide (Cancers, 6, 2014 and 2155). The tumorigenic roles of Epstein-Barr virus in oral cancer are unclear. Literature search results are conflicting and dependent on various factors such as geographical/regional variations, sociocultural lifestyles, dietary habits, chewing/smoking tobacco habit. This study is the first original observation about frequency of Epstein-Barr virus among South Indian tobacco-chewing patients to elucidate its involvement in oral carcinogenesis and to know whether this can be a valuable diagnostic and prognostic indicator. MATERIALS AND METHODS A total number of 75 tobacco chewer subjects aged between 23 and 76 years with histopathologically confirmed oral potentially malignant disorders (25), oral squamous cell carcinoma (25), and age-matched healthy controls (25) formed the study group. Immunohistochemical expression of Epstein-Barr virus latent membrane protein 1 was assessed among cases and healthy controls. RESULTS Out of the total 75 subjects, six subjects (8%) were positive for Epstein-Barr virus antigen and 69 subjects (92%) negative. The antigen positivity was observed among two cases of moderately differentiated oral squamous cell carcinoma, two cases of leukoplakia, and two healthy controls. CONCLUSION No significant association between Epstein-Barr virus positivity was observed among oral potentially malignant disorders and oral squamous cell carcinoma among South Indian tobacco-chewing patients. This can be partially explained by the methodology employed, by the patient population analyzed and different habits in various geographical regions.

Abstract
BACKGROUND Recent studies have revealed the involvement of hedgehog (Hh) signaling component in proliferation and invasive behavior of many carcinomas. AIM This study aims to identify the expression of sonic Hh (SHH) protein of SHH pathway in oral epithelial dysplasia and oral squamous cell carcinoma (OSCC) using SHH (H-160) (Santa Cruz, sc-9042) which could have therapeutic implication in future. MATERIALS AND METHODS A total of 250 cases comprising 50 normal oral mucosa, 50 cases of oral epithelial dysplasia, 50 well, 50 moderate and 50 poorly differentiated OSCCs were included in the study. Immunohistochemical evaluation of SHH protein expression was conducted using monoclonal antibody. Interpretation of the expression was done by immunoreactive score of Remmele and Stegner (IRS) scoring method. STATISTICAL ANALYSIS Chi-Square test was used to analyze the results. RESULTS The study showed that SHH signaling molecules are highly expressed in OSCC, and their expression was mainly in the cytoplasm of epithelial cells. CONCLUSION The SHH signaling component is associated with the pathological parameter in OSCC and oral epithelial dysplasia.

Abstract
Background: The Bcl-2 (B-cell lymphoma) gene product also known as apoptotic inhibitor is expressed in many normal and tumor tissues. This Bcl-2 gene protects the cell by blocking postmitotic differentiation from apoptosis, thus maintaining the stem cell pool. Objective: To study the expression of Bcl-2 protein in ameloblastoma and keratocystic odontogenic tumor (KCOT) to determine their apoptotic behaviors and to analyze biological nature of KCOT, which has higher proliferative potential and aggressive clinical behavior like odontogenic tumors. Materials and Methods: Formalin-fixed paraffin sections of ameloblastoma (n = 20) and KCOT (n = 20) are considered for immunohistochemical analysis using monoclonal antibody against antihuman Bcl-2 oncoprotein. Lymphomas (n = 3) were used as controls. Statistical Analysis: The statistical analysis was performed using software package of social science version 16. The data were analyzed using Chi-square test and Student's t test. In all the above tests, P < 0.05 was accepted as statistically significant. Results: The positive ratio of Bcl-2 was 85% (17/20) in ameloblastoma, 85% (17/20) in KCOT and 100% (3/3) in lymphomas. Bcl-2 was expressed in peripheral cells and few scattered cells of stellate reticulum in ameloblastoma. KCOT showed strong positivity for Bcl-2 mainly in the basal layer. Interpretation and Conclusion: The present study demonstrates the aggressive nature of KCOT and intrinsic growth potential of its lining epithelium. This study clearly demonstrates that KCOT like ameloblastoma demonstrates aggressive clinical and noticeable invasive behavior. Therefore, it is now considered as no longer a developmental cyst but as odontogenic tumor.

Abstract
Osteosarcomas are highly malignant bone tumours. Its appearance in craniofacial bones is a rare entity and accounts for only 1% of all head and neck malignancies. We present an uncommon case report of a 42 year old male patient with osteosarcoma of left maxilla, which was successfully excised under general anesthesia. The patient reported to us with a history of pain, swelling, pus discharge and tooth extraction, which led to the differential diagnosis of suppurative osteomyelitis, dentoalveolar abscess, benign odontogenic tumour, an infected cyst etc. Histopathological examination of incisional biopsy was reported as chondromyxoid fibroma which is a rare benign tumour. However the excisional biopsy specimen was reported as osteosarcoma of maxilla. The clinical presentation, diagnostic challenges and its therapeutic approach are addressed. This case serves to emphasize the need to recognize osteosarcoma when it presents in unexpected locations, especially because of its rarity.

Abstract
The nephrotic syndrome (NS) is a well documented complication of hematological malignancies. However, chronic myeloid leukemia (CML) is rarely complicated by the NS, and it occurs usually after allogenic stem cell transplantation or interferon alpha therapy for CML. The NS as a complication of untreated CML is also rare. We report a 31-year-old patient who presented with features of The NS. He was diagnosed to have CML one year ago and was on irregular treatment with imatinib mesylate. The renal biopsy and immunofluorescence revealed membrano-proliferative glomerulonephritis type I. The patient was retreated with imatinib mesylate and the NS resolved gradually over three months. This maybe the third case in literature of membrano-proliferative glomerulonephritis associated with CML.
