RESUMEN
INTRODUCTION: Gallbladder cancer is an aggressive cancer with short median survival from the time of diagnosis. Improved understanding of the pathological molecular mechanisms of gallbladder carcinogenesis is important to refine the diagnosis, prognosis, and also to develop novel targeted therapies for patients with advanced Gallbladder cancer (GBC) malignancy. Ki-67 is a marker of cell proliferation and its detection by immunohistochemistry is considered to be an effective method for the detection of prognosis in several tumors. In the present study, we have analyzed expression of immunohistochemical marker Ki-67 in gallbladder carcinoma and its correlation with clinicopathological and radiological parameters. MATERIALS AND METHODS: This prospective observational study was conducted from December 2017 to July 2020. The patients of newly diagnosed gallbladder cancer were enrolled as per the inclusion and exclusion criteria defined in the study protocol. Contrast-enhanced computer tomography of the chest and abdomen and serum tumor markers such as carbohydrate antigen (CA)-19.9, carcinoembryonic antigen, and CA 125 were done. Immunohistochemical expression of Ki-67 was evaluated on biopsy tissue from the gallbladder mass. RESULTS: Fifty newly diagnosed patients of carcinoma gallbladder were included in the present study. The correlation was studied between clinicodemographic parameters and Ki-67, but no association was found with age, gender, and symptoms. There was a weak positive correlation between Ki-67 and direct bilirubin, serum glutamic pyruvic transaminase, serum glutamic oxaloacetic transaminase, and alkaline phosphatase (P = 0.094; 0.126; 0.542; and 0.328, respectively). There was a weak positive correlation between body mass index (Kg/m2) and Ki-67, but this correlation was not statistically significant (P = 0.304). CONCLUSIONS: Ki-67 is a marker of proliferation and it correlated with histological differentiation, jaundice and liver function tests, presence of stones, and location of metastases but did not correlate with stage and extent of disease.
RESUMEN
INTRODUCTION: Gallbladder cancer exhibits striking variability in the global rates, reaching epidemic levels for some regions and ethnicities. The basis of its variability resides in differences in environmental exposure and intrinsic genetic predisposition to carcinogenesis. There is little information present regarding genetic and molecular alterations in gall bladder cancer (GBC). We, therefore, have evaluated the molecular marker expression in GBC and studied their correlation with clinicopathological staging. MATERIALS AND METHODS: This prospective observational study was conducted on newly diagnosed GBC patients from July 2017 to July 2020. After complete staging workup, the GBC biopsy samples paraffin block was tested for molecular markers estrogen receptor (ER), progesterone receptor (PR), p53, p16, Human epidermal growth factor receptor 2 (HER 2-neu), Survivin, Enhancer of zeste homolog-2 (EZH2), and Cyclooxygenase-2 (COX-2) expression by immunohistochemistry. RESULTS: Fifty newly diagnosed patients of carcinoma gall bladder were included in the present study. Age was ranged from 29 - 69 years (mean 53.42). p53 was the most common positive marker in 74% of patients, survivin in 58%, COX-2 in 44%, and p16 in 42% whereas Her 2 neu and EZH-2 were positive in 16% of patients each. None of the patients of GBC were ER or PR positive. There was a significant difference between the various groups in terms of the distribution of histological grade and Her 2 neu (χ2 = 9.886, P = 0.014) but not with other markers. Furthermore, there was a significant difference in terms of distribution of p16 and p53 with stage (χ2 = 7.017, P = 0.037 and χ2 = 5.861, P = 0.033) respectively. CONCLUSIONS: The present study shows the expression of molecular markers Her2 neu, p53, p16, survivin, COX-2, and EZH-2 in GBC. Now the time has come, and it is also the need of the day to establish early biomarkers of this highly lethal malignancy. It can be used in future for the detection of disease in the early phase and targeted therapy.
RESUMEN
Squamous cell carcinoma is known to occur as a serious complication of chronic burns, scars, and ulcers, but very rarely has it been reported to occur in a long-neglected meningocele. The authors wish to present the case of a 21-year-old man who presented to us when a previously asymptomatic meningocele developed a squamous cell carcinoma on the meningocele sac. The squamous cell carcinoma was excised in toto, followed by excision of the redundant meningocele sac. The neural placode was closed and dural closure done with an artificial dural patch. Reconstruction of the defect thus created was performed by a lumbar perforator-based reverse latissimus dorsi myocutaneous flap. The patient did not develop any postoperative neurological deficits and made an uneventful recovery in the postoperative period. He received adjuvant radiation therapy and is doing well at 4 months' follow-up.

BACKGROUND: Localization of primary tumor in insulinoma is often difficult. We evaluated the role of 68Ga-DOTA-Nal3-Octreotide (DOTANOC) PET/CT for localization of primary tumor in patients with clinical and biochemical suspicion of insulinoma. METHODS: Data of 35 patients (age: 38.4±16.5 years) who underwent 68Ga-DOTANOC PET/CT for clinical and biochemical suspicion of insulinoma (hypoglycemia, raised serum insulin and C-peptide levels) were retrospectively analyzed. PET/CT images were evaluated visually and semiquantitatively (SUV) by two experienced nuclear medicine physicians. A definite lesion in pancreas on non contrast CT showing increased 68Ga-DOTANOC was taken as positive. In the absence of CT lesion focal 68Ga-DOTANOC uptake in the pancreas more than liver was taken as positive. All patients had also undergone conventional imaging (CIM) (CT/MRI/endosonography) and their reports were retrieved for comparison. Histopathology and/or imaging/clinical/biochemical follow up (minimum 6 months) was used as reference standard. RESULTS: The mean serum insulin levels was 51.6±54 µIU/mL and C-peptide level was 6.9±7.3 ng/mL. 68Ga-DOTANOC PET/CT was interpreted as positive in 11 patients (31.5%) and negative in 24 (68.5%). PET/CT demonstrated total 16 pancreatic lesions in 11 patients. In two patients it also showed both liver and lymph nodal metastases. 68Ga-DOTANOC PET/CT was true positive in 8, true negative in 1, false positive in 3 and false negative in 23 patients. Per patient based sensitivity of PET/CT was 25.8% (95% CI: 11.8-44.6), specificity was 25% (95% CI: 0.6-80.5) and accuracy was 25.7%. The mean SUVmax of pancreatic lesions was 13.8±11.1. On comparison no significant difference was seen between CIM and PET/CT on patient based (P=1.00) or lesion based comparison (P=0.790). CONCLUSION: 68Ga-DOTANOC PET/CT has limited utility for localizing the primary tumor in patients with clinical and biochemical suspicion of insulinoma. However, it might be useful for differentiating benign and malignant insulinoma. Further prospective comparative studies are warranted.

PURPOSE: The purpose of the present study was to evaluate the diagnostic accuracy of (68)Ga-DOTANOC positron emission tomography (PET)/CT in patients with suspicion of pheochromocytoma. METHODS: Data of 62 patients [age 34.3 ± 16.1 years, 14 with multiple endocrine neoplasia type 2 (MEN2)] with clinical/biochemical suspicion of pheochromocytoma and suspicious adrenal lesion on contrast CT (n = 70), who had undergone (68)Ga-DOTANOC PET/CT, were retrospectively analyzed. PET/CT images were analyzed visually as well as semiquantitatively, with measurement of maximum standardized uptake value (SUVmax), SUVmean, SUVmax/SUVliver, and SUVmean/SUVliver. Results of PET/CT were compared with (131)I-metaiodobenzylguanidine (MIBG) imaging, which was available in 40 patients (45 lesions). Histopathology and/or imaging/clinical/biochemical follow-up (minimum 6 months) was used as reference standard. RESULTS: The sensitivity, specificity, and accuracy of (68)Ga-DOTANOC PET/CT was 90.4, 85, and 88.7%, respectively, on patient-based analysis and 92, 85, and 90%, respectively, on lesion-based analysis. (68)Ga-DOTANOC PET/CT showed 100% accuracy in patients with MEN2 syndrome and malignant pheochromocytoma. On direct comparison, lesion-based accuracy of (68)Ga-DOTANOC PET/CT for pheochromocytoma was significantly higher than (131)I-MIBG imaging (91.1 vs 66.6%, p = 0.035). SUVmax was higher for pheochromocytomas than other adrenal lesions (p = 0.005), MEN2-associated vs sporadic pheochromocytoma (p = 0.012), but no difference was seen between benign vs malignant pheochromocytoma (p = 0.269). CONCLUSION: (68)Ga-DOTANOC PET/CT shows high diagnostic accuracy in patients with suspicion of pheochromocytoma and is superior to (131)I-MIBG imaging for this purpose. Best results of (68)Ga-DOTANOC PET/CT are seen in patients with MEN2-associated and malignant pheochromocytoma.

It is an endogenous defence mechanism regulating multiple cellular pathways like apoptosis, inflammation, immune response and pathogen clearance and acts as a modulator of pathogenesis. This article highlights the emerging role of autophagy in inflammation and regeneration of human dental pulp. It emphasizes exploring autophagy and autophagy agonists as potential targets for the development of novel therapeutic interventions.
RESUMEN
Prostate cancer is a significant cause of cancer-related mortality among men worldwide, necessitating the exploration of prognostic biomarkers to aid in accurate risk assessment and treatment decision-making. This cross-sectional study aimed to comprehensively evaluate the role of Ki-67 as a prognostic marker in prostate cancer by examining its association with clinicopathological parameters. A total of 102 archived cases of prostate core biopsy specimens, histopathologically reported as prostate carcinoma, were included in this study. Histopathological grading was conducted using Gleason's scoring and grading system based on morphology. The statistical software "R" was utilized for data analysis. Kruskal-Wallis test and Fisher's exact test were employed to analyze the association between Ki-67 expression and clinicopathological parameters. The study revealed significant correlations between Ki-67 expression and various clinicopathological parameters in prostate cancer cases. High Ki-67 expression levels were associated with higher Gleason scores, increased incidence of perineural invasion, advanced T stages, lymph node metastasis, presence of distant metastasis, and higher prognostic stage groups. The findings of this cross-sectional study support the potential of Ki-67 as a prognostic marker in prostate cancer. The significant associations observed between Ki-67 expression and clinicopathological parameters indicate its usefulness in risk stratification and treatment decision-making. The incorporation of histopathological grading, including Gleason scoring, and analysis of perineural invasion strengthens the validity of the study. Ki-67, in combination with morphological assessments, provides valuable prognostic information for prostate cancer patients.

Background: An epidermoid cyst is a benign keratin-filled cyst, commonly located in the face, scalp, neck, and trunk. Although it is a common benign cystic neoplasm, large series of analyses in English literature are still scarce. To comprehend the clinical and pathological variation of epidermoid cysts in the sub-Himalayan region of India, as well as their clinical implications for late diagnosis, a retrospective study on epidermoid cysts was conducted. Materials and Methods: This was a retrospective observational study conducted on 217 cases of epidermoid cyst subjected for fine-needle aspiration cytology over a period of 3.6 years (from 2018 to 2021). The clinical details and other epidemiological data were archived from the pathology requisition forms. Results: It showed slight male preponderance with head and neck site as the most common area. Most patients were adults. Few uncommon sites were also seen namely breast, parotid, epididymis, and tonsils. Few large lesions were identified measuring up to 10 cm. The skin changes were seen in 5.5% cases, 0.9% cases show extreme ulceration, and 4.1% cases show foreign body giant cell reactions. Due to the province's steep terrain and limited access to medical services, the majority of patients arrived at out patient department (OPD) late. Conclusion: The findings suggest that fine-needle aspiration can be used as a quick diagnostic test even in remote areas by the general practitioner who can send the slides for evaluation to a pathologist. Many times, clinically looking epidermoid cyst can reveal certain challenging entities such as a biphasic fibroepithelial tumor with cystic squamous metaplasia and proliferating pilar tumor in our series. The study of this lesion is also needed for early diagnosis as long-standing lesion may rupture and cause requirement of extensive treatment followed cosmetic impairment.
RESUMEN
Background: Secretory carcinoma (SC) is a newly described entity which has been often misdiagnosed earlier as acinic cell carcinoma on cytology. Diagnosing SC was initially based upon identifying the ETV6:NTRK3 fusion gene with the help of fluorescence in situ hybridization (FISH). Lately, with more knowledge of the reliable histomorphology, cytology, and immunohistochemistry features, definitive diagnosis can be confidently made without the help of FISH in almost every case. Materials and Methods: Six histologically confirmed cases of SC were studied. The cytology slides of all the six cases were retrieved and reviewed to identify the characteristic features which could have helped in raising the possibility of SC on fine needle aspiration cytology itself. Cell blocks were also studied, wherever available. Results: Patients were all male with average age of 35.2 years. The six cases in the current study demonstrated at least focal cytoplasmic vacuolization of varying sizes, papillae formations, and bland nuclear features on fine needle aspirate smears. It was also seen that S-100 and mammaglobin immunohistochemistry (IHC) are very helpful in confirming the diagnosis. Conclusions: The results of the current study highlight the cytomorphological features which may help in clinching the diagnosis SC on cytology itself. They also highlight certain cytological features which help to rule out the other differential diagnoses.
RESUMEN
The management of neuroendocrine tumours is challenging when curative surgery is ruled out because of distant metastases. We report a case of gastrointestinal carcinoid with bilateral ovarian metastases in a 50-year-old female who received octreotide therapy followed by peptide receptor radionuclide therapy and surgery thereafter. Somatostatin receptor expression on neuroendocrine tumours has implications in diagnosis and therapy. (68)Ga-DOTA-NOC PET is a recent advancement in the field of somatostatin receptor imaging. The lesions which demonstrate tracer uptake on positron emission tomographic studies can be further planned for treatment with octreotide and (177)Lu-DOTA-TATE. The case in discussion responded well to non-invasive treatment options before proceeding to definitive surgical management.

Laryngeal chondrosarcomas are rare tumors. They usually clinically present late as they are slow growing tumors. We reported a case of laryngeal chondrosarcoma in a middle-aged male present with hoarseness of voice along with stridor. The tumor was located in subglottis with destruction of cricoid cartilage. The histopathological evaluation is particularly important as diagnosis and grading needs strict follow up of criteria.
RESUMEN
OBJECTIVE: The oral squamous cell carcinoma (OSCC) treatment protocol depends upon lymph node metastasis. Elective neck dissection for early-stage OSCC (pT1/T2) elective neck dissection reduces the morbidity rate. It also reduces the overall survival and thus it becomes important to detect lymph node metastasis in early-stage OSCC. MATERIAL AND METHOD: Various histomorphological parameters have been studied to predict nodal metastasis in early-stage OSCC. We aim to evaluate these parameters in the context of nodal metastasis. 78 cases of early-stage OSCC were included in the study with histopathologic parameters like tumor size, grade, tumor depth of invasion (DOI), lymphovascular invasion (LVI), perineural invasion (PNI), worst pattern of invasion (WPOI), and lymph node level. RESULTS: Out of the 78 patients, 32 patients had lymph node metastasis. T stage, DOI, LVI, and WPOI showed statistically significant deviance from the null model (P-values of 0.007, 0.01, 0.04 and 0.02 respectively). The Odds Ratio (OR) of T stage, DOI, LVI and WPOI were 4.45 (95% C.I =1.47-14.1), 4.4 (95% C.I =1.32-15.88), 8.12 (95% C.I =1.002-198.20), and 3.39 (95% C.I =1.24-9.74) respectively. On multivariate analysis (Firth logistic regression) using DOI, LVI, and WPOI as independent variables, only T-stage and WPOI retained statistical significance. CONCLUSION: The prognostic information supplied by evaluating DOI, LVI, and WPOI warrants the inclusion of these parameters in the standard reporting format for all cases of OSCC.

Introduction Urothelial carcinomas are the most common types of bladder tumors that have recently shown a changing trend in treatment protocols with the introduction and approval of immune checkpoint inhibitors. The most important immune checkpoint lies with the PD-1-PD-L1 axis. Although multiple drugs have been approved, there is uncertainty about patient selection criteria and diagnostic assays. Recent studies related to the laboratory-developed tests have opened up the horizon of PD-1 and PD-L1 immunohistochemistry even at resource-constrained laboratories. We propose to study these immunohistochemistry markers in our laboratory using newer clones. Materials and Methods We selected 116 consecutive cases of transurethral bladder tumor resection from our laboratory archive and applied PD-1 and PD-L1 immunohistochemistry. The study was approved by the institution's ethics committee. Results We found high expression of PD-1 and PD-L1 in urothelial carcinoma even with different cut-offs of PD-L1. Muscle invasion, lamina invasion, and grade of carcinoma had a statistically significant effect on the expression; however, age and sex did not affect the expression. Conclusion Based on our current study, we can conclude that the clones used in our study show high expression in urothelial carcinoma and can aid in patient selection and treatment protocol, irrespective of age and sex.
RESUMEN
Aims and objective This study describes postmortem and histopathological findings to understand the internal progression of methanol poisoning. The study also aims to examine clinical, biochemical, and histological changes seen with methanol poisoning. Materials and methods The study describes the methanol poisoning tragedy that occurred in February 2019 in the Haridwar district of Uttarakhand. Ninety-one patients were admitted to the hospital, four were brought dead, four died within a few hours of admission (designated as early deaths), and four died between 10 and 45 days of hospitalization (designated as late deaths). A medicolegal autopsy was performed on all 12 deaths. Gross external and internal findings were noted, and routine viscera and blood were preserved and sent to Uttarakhand's Forensic Science Laboratory (FSL) to estimate methyl alcohol. A section of the optic nerve was taken from the optic chiasma for histopathological examination. Data were collected retrospectively from records. All data were tabulated and analyzed using Microsoft Excel version 2019. The study was approved by the Institutional Ethics Committee of All India Institute of Medical Sciences (AIIMS), Rishikesh (249201), Uttarakhand, India. Results Methanol poisoning is a health-associated disaster in many regions of India. Autopsy, including histopathological examination, could elicit the adverse effects of methanol on different organs. Their mean age was 37.7 years (range 21-70), and 67% (n = 8) of all victims were in the age range of 30-50 years. The average methyl alcohol level reported among hospital deaths and brought dead was 116.08 mg/dl and 224.6 mg/dl, respectively. A blurred vision had been their most common complaint, identified in 75% (n = 6), followed by vomiting and abdominal pain, while 50% (n = 4) had features of respiratory insufficiency. Mean pH and bicarbonate levels among hospital deaths were 6.61 mmol/l and 6.18 mmol/l, respectively. An autopsy revealed signs of hypoxia in all cases. Internal organs were congested. Severe metabolic acidosis leading to the respiratory failure was the cause of death in early deaths. Cerebral and pulmonary edema consequent upon septicemic shock was the cause of late deaths. A case with the most extended survival duration showed cerebral edema with intracerebral hemorrhage. Cirrhotic liver, along with features of renal failure, was an additional internal finding in late deaths. Optic nerve histopathology showed no demyelination or axonal necrosis; however, mild edematous changes were evident. Conclusions Methanol poisoning is one of the manmade disasters in the developing world. There are various adverse effects of different organs and organ systems inside the body. Timely intervention and diagnosis can save several lives. The organ-directed meticulous autopsy can help autopsy surgeons in establishing the diagnosis and thus help the judiciary in delivering justice to the sufferers.
RESUMEN
BACKGROUND: Mucosal melanoma is a rare but aggressive tumor associated with a poor prognosis arising from pigmented cells called melanocytes. They are usually asymptomatic and present in an advanced stage. It has an aggressive clinical outcome and is proven to be of poor prognosis. MATERIALS AND METHODS: This is a retrospective review of the computer database and clinical records at the All India Institute of Medical Sciences, Rishikesh, India. The data between 2018-2022 were reviewed for all small biopsy or excision specimen-proven cases of oral mucosal melanoma. RESULTS: The most common site of involvement in the head and neck region is the nasal cavity and paranasal sinuses. In this retrospective study from our institute, all three cases presented involved oral cavities. The median age of presentation was 51 years. Some literature specifies male preponderance. Our patients presented clinically with a black nodule in the oral cavity, which was increasing in size and associated with bleeding. A biopsy performed confirmed the diagnosis of melanoma based on the morphology and immunohistochemical profile of the tumor cells. CONCLUSION: Surgical resection is the mainstay treatment, followed by radiation postoperatively to reduce local and regional recurrence. Mucosal melanoma has a poor prognosis, and the majority of patients develop incurable metastatic disease.
RESUMEN
Introduction Lymphocytic thyroiditis is an autoimmune disorder and one of the major causes of hypothyroidism. On cytomorphology, it is characterized by follicular destruction by lymphocytes with elevated biochemical markers, including a panel of autoantibodies against thyroid antigens. This study aimed to determine the prevalence of various cytological features of lymphocytic thyroiditis and their correlation with clinical presentation and biochemical parameters. Materials and methods We conducted a hospital-based cross-sectional study of 105 patients diagnosed with lymphocytic thyroiditis on cytology at our tertiary care center in the Himalayan foothills from December 2018 to December 2019. We recorded and analyzed baseline demographic characteristics, clinical features, and biochemical parameters to assess correlations between cytological findings and grades. Results The study included 105 patients with lymphocytic thyroiditis (90 females, 15 males). The study population age ranged from 11 years to 80 years, with the disease most common in patients aged 21 to 40 years. Grade II was the most common cytological presentation (n=65, 62%). Thyroid-stimulating hormone levels were elevated in 33.3% of cases, and anti-thyroid peroxidase levels were elevated in all 25 cases for whom data were available (p>0.05). Conclusion Cytological diagnosis of lymphocytic thyroiditis was compatible in all cases in the study. However, cytological grading did not correlate with the clinical presentation and biochemical parameters. The diagnosis of lymphocytic thyroiditis could be missed if clinicians use clinical findings and biochemical parameters alone.
