Liver Transplants from Donors with Schistosomiasis: Clinical and Epidemiological Profile of Patients at Clinics Hospital of Sao Paulo, Brazil

Abstract Organ transplantation is a surgical procedure that consists of awarding an organ. Considering that the transplantation of an organ or tissue is very competitive, due to the low rate of donors and as the function of the liver is preserved even in controlled schistosomatic fibrosis, it is possible to donate the organ even with the liver infected by verminosis. By analyzing the prevalence and evolution of liver donors with schistosomiasis in liver transplants performed at Hospital das Clínicas, Faculty of Medicine, University of São Paulo - HCFMUSP. This is a descriptive study, consisting of a series of cases, with a retrospective and cross-sectional analysis. The study evaluated the medical records of patients being followed up at the Liver Transplant Outpatient Clinic, at HCFMUSP, from January 2002 to December 2020. The Department of Pathology at USP found 16 patients with records of schistosomiasis reports, of which only one was effective as a donor, since the other patients were excluded due to the state of law of the organ. An analysis showed that almost all donors were men with schistosomiasis with a mean age of 52.55 years. In this context, there was a prevalence of a case of a liver donor with the hepatointestinal form of schistosomiasis, later the organ was transplanted, and the recipient, presented a good evolution until this moment, having been analyzed clinically and laboratory. It is noteworthy that this is the first HCFMUSP study that evaluates liver donors with schistosomiasis mansoni and the evolution of the respective recipient. Keywords: Schistosomiasis.

Haja vista que o transplante de um órgão ou tecido é muito concorrido, em decorrência da baixa taxa de doadores e como a função do fígado está preservada mesmo na fibrose esquistossomatica avançada é possível doador o órgão mesmo com o fígado infectado pela verminose. O objetivo desse estudo foi analisar a prevalência e evolução de doadores fígado, portadores de esquistossomose, nos transplantes hepáticos realizados no Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo - HCFMUSP. Trata-se de um estudo descritivo, composto por uma série de casos, sendo a analise retrospectiva e de corte transversal. O estudo avaliou os prontuários de pacientes em seguimento no Ambulatório de Transplante hepático, do HCFMUSP, no período de janeiro de 2002 a dezembro de 2020. O departamento de Patologia da USP constatou 16 pacientes com registros de laudos de esquistossomose, dos quais somente um foi efetivado como doador, uma vez que os outros pacientes foram excluídos em razão do estado de deterioração do órgão. A análise mostrou que quase a totalidade dos doadores eram homens com esquistossomose com idade média de 52,55 anos. Dentro desse contexto, houve a prevalência de um caso de um doador hepático portador da forma hepatointestinal de esquistossomose, posteriormente o órgão foi transplantado, e o receptor, apresentou uma boa evolução até este momento tendo sido analisado clinicamente e laboratorialmente. Vale ressaltar, que este é o primeiro estudo do HCFMUSP que avalia doadores de hepáticos portadores de esquistossomose mansoni e a evolução do respectivo receptor. Palavras-chave: Esquistossomose.

Epidemiological and clinical description of patients with oropharyngeal cancer treated in a public oncology referral hospital in Chile.

The incidence of squamous carcinoma of the oropharynx (OPSCC) has presented an increase worldwide, a fact that occurs along with a phenomenon of epidemiological transition, whose pathogenesis is linked to human papilloma virus (HPV) in a significant part of the cases. Published evidence at the Latin American level is scarce. The present study aims to evaluate the epidemiological and clinical characteristics of patients with oropharyngeal cancer treated in a public oncology reference centre in Chile. A cross-sectional study was carried out. Patients with histological confirmation of OPSCC aged 18 years or older, referred to the National Cancer Institute of Chile between 2012 and 2023 were included. The association with HPV was determined by immunohistochemistry for p16. 178 patients were analysed, most of them in locoregionally advanced stages involving the palatine tonsil. Seventy-seven percent were male, with a median age of 60 years. Sixty-seven percent of patients were positive for p16, with a progressive increase to 85% in the last 2 years of the study. The p16(+) patients were younger and had fewer classical risk factors. Primary treatment was radiotherapy in 94% of patients. The epidemiological profile of patients with OPSCC treated in a Chilean public oncology referral centre reflects the epidemiological transition observed in developed countries. This change justifies the need to adapt health policies and conduct research that considers the characteristics of this new epidemiological profile.

Epidemiology of acute stroke presentations to an emergency ambulance service

Objective Stroke is a devastating condition with significant societal and personal costs. Attempts to improve outcomes have increasingly focussed on improvements in prehospital care of these patients. This study aims to provide an epidemiologic profile of stroke presentations to an ambulance service. Methods A descriptive quantitative analysis of linked administrative and clinical patient data across prehospital, hospital, and death records from a two-year period (2016–2017), was used to profile the acute stroke cohort transported by ambulance in Queensland, Australia. The epidemiologic profile of patients and sub-type of stroke is presented. Results There were 17,603 presentations of suspected acute stroke in Queensland during the study period amongst 2,078,140 ambulance responses. A total of 11,578 patients had a confirmed diagnosis of stroke at the time of their final discharge. Of this population 49.8% suffered an Acute Ischaemic Stroke, 12.9% had intracerebral haemorrhage, 4.5% had subarachnoid haemorrhage and 32.8% were transient ischaemic attack. Of those with acute ischaemic stroke (AIS) 9.2% were due to a large vessel occlusion. The three-month stroke related fatality rate was 10%. Conclusion This study demonstrated a lower annual presentation rate of stroke, to an emergency ambulance service, than would be expected based on population studies while the overall mortality rate amongst this population was higher. The reasons for these differences warrant further investigation.

Clinical-epidemiological profile of vestibular migraine patients: Indian scenario

Background: The main objective of this study was to observe the Indian clinical scenario and analyse the clinical and epidemiological profile of patients with vestibular migraine. Methods: This is a retrospective observational descriptive study. The outpatient records of the vertigo clinic at Department of Otorhinolaryngology of SGT medical college, Budhera, Gurgaon, Haryana was assessed from April 2023 to July 2023. Patients who were diagnosed with vestibular migraine based on ICD classification as follows was included in the study.   Results: Study population predominantly comprised of 77% (17) females and 23% (5) of males. Almost 80% of the study population belonged to age group 31-40 years. Each episode of vertigo lasts for seconds in 50% of the patients and minutes in 45% of the patients. All patients had episodic vertigo.59% of patients described the vertigo as rotatory,18 % of the study population reported imbalance,18 % described swaying and 5% reported blackouts. Most of the examination was normal except 5 out of 22 patients reported giddiness on testing vertical saccades. Conclusions: Vestibular migraine is an underdiagnosed condition in India, there’s not much research and awareness, hence this study aims to overcome these limitations. Most of the patients were middle aged women. The physical and audiological examination of most patients were normal but showing abnormalities on testing saccades.

Syphilis: Is it Back with a Bang?

Syphilis was brought under control with the advent of penicillin. However, in recent times, a rise in the incidence of syphilis has been reported by Centers for Disease Control and Prevention (CDC). To study the clinical and epidemiological profile of patients with syphilis attending sexually transmitted infection (STI) clinic at tertiary care center. Observational, cross-sectional analysis of sociodemographic, clinical, and investigational data of all syphilis patients visiting STI clinic from August 2019 to July 2021 was done and analyzed. Out of 1330 STI patients that attended the clinic, 15.04% (n = 200) were diagnosed with syphilis, among them 72% (n = 144) were males, and 28% (n = 56) were females, with male-to-female ratio of 2.5:1. Of these 24.5% (n = 49) had primary, 44.5% (n = 89) had secondary, 30.5% (n = 61) had latent, and 0.50% (n = 1) had congenital syphilis. Among secondary syphilis patients, rash was the most common presentation seen in 43 patients, followed by condyloma lata in 30, palmoplantar syphilis in 17, oral mucous patch in 3, and iridocyclitis in 3 patients. Human immunodeficiency virus (HIV) was positive in 16.5% (n = 33). Herpes genitalis was the most common coinfection among 25 patients who were diagnosed with mixed venereal disease. RPR titer was positive in all 200 patients, with 1:16 titer being most common. India is experiencing a new trend in the prevalence of syphilis, mainly due to the changes in risk behavior, misconceptions, and social stigma associated with STIs, improved laboratory diagnosis, and increased public awareness. Particularly secondary and latent stages have shown a rising trend over the past few years. Awareness about safe sexual practices and contraception is very important to control the current resurgence.

Monitoring of pregnancy and labour by cardiotocography: 155 cases from the maternity ward of the institut hygiène sociale Hospital in Dakar

Objectives: To determine the epidemiological and clinical profile of patients monitored by cardiotocography, to assess the performance of the device in detecting labour abnormalities and to identify factors influencing the results of cardiotocography. Patients and methods: We conducted a retrospective, descriptive and analytical study of labour monitoring and pathological pregnancies using the cardiotocograph at the Maternity Unit of the Institut Hygiène Sociale hospital in Dakar over a two-year period from 1 January 2019 to 31 December 2020. All cardiotocographic tracings were subject to a 2nd blind interpretation by a senior. The results were interpreted using the 2007 classification of the Collège National des Gynécologues et Obstétriciens Français (CNGOF). An APGAR score of less than 7 at 1 minute was defined as neonatal asphyxia. Data were collected from the patients' records and entered on a computerised form. Data analysis was performed using SPSS version 22 software. Results: During the study period, 208 patients were monitored with the cardiotocograph out of a total of 4123 deliveries, i.e. a frequency of use of 5%. Of these, 155 were included in the study (74.5%). These included 118 parturients (76.1%) and 37 pathological pregnancies (23.9%). The epidemiological profile of the patients was that of a woman aged 28 years on average, of low socio-economic status (83.2%), paucigest (48.4%), pauciparous (46.5%), carrying a full-term pregnancy (67.7%) and living outside the South District (72.3%). Ninety-seven FHR tracings contained abnormalities (62.2%). These included 47 pathological FHR tracings (30.1%) and 50 FHR tracings at intermediate risk of acidosis (32.1%). The basic rhythm was most often normal (87.2%). The abnormalities found were bradycardia (4.5%), tachycardia (7.7%) and absent rhythm (0.6%). Variability was mostly normal (78.9%). However, it was reduced in 12.2% of cases. Fifty tracings showed accelerations (32.1%) and decelerations were noted in 49 foetuses (31.4%). These were most often early (16%) or late (7.1%) decelerations. Tocography was mostly normal (60%). The abnormalities noted were dominated by hypertonia (11.7%) followed by hyperkinesia of intensity (7.7%). The majority of patients (54.8%) had given birth by caesarean section and the indications were dominated by the non-reassuring state of the foetus (69.4%). Most of the newborns had an APGAR score greater than 7 at 1 minute (82.7%) and 5 minutes (91.7%). Comparison of the results of the ERCF with the neonatal status revealed 20 true positives, 7 false negatives, 27 false positives and 102 true negatives, giving the ERCF a sensitivity of 74.1%, a specificity of 79.1%, a positive predictive value of 42.1% and a negative predictive value of 93.6% for the diagnosis of non-reassuring foetal status. A bivariate analysis enabled us to identify factors associated with the occurrence of perinatal asphyxia. Basic rhythm abnormalities (p = 0.001) and variability (p = 0.004), hypertension in the pregnant woman (p = 0.034), premature rupture of the membranes of more than 6 hours (p = 0.044) and intrauterine growth retardation (p = 0.013) were significantly associated with the risk of neonatal asphyxia. Conclusion: Cardiotocography is a powerful tool for monitoring labour, but its effectiveness is influenced by the conditions in which it is performed and the qualifications of the operator.

Study of the clinical and epidemiological profile of heart failure

The purpose was to describe the clinical and epidemiological profile of patients with Heart Failure (HF) treated at a specialized clinic in the Unified Health System. This is a descriptive, individual and cross-sectional study, which collected data from medical records of patients with HF. Patients were divided into three groups according to the stroke volume: preserved, mid-range and reduced. A total of 545 medical records were evaluated, with a mean age of 64.9 ± 13.6 years, and 55.6% of which were male. Hypertension (76.7%), coronary artery disease (38.5%), and diabetes mellitus (37.2%) were the main risk factors. Myocardial ischemia was the main etiology (36.40%), followed by Chagas disease (20.22%). The valve etiology was frequently associated with reduced LVEF (left ventricular ejection fraction) (Pearson's ρ <0.06), with mid-range LVEF (Pearson's ρ <0.10) and with preserved LVEF (Pearson's ρ <0.39). The ischemic etiology was frequent in preserved LVEF (Pearson's ρ <0.08). The findings showed a strong association between valve disease and preserved LVEF; frequent association between mid-range LVEF and valve and ischemic disease; frequent association between valve disease and reduced LVEF.

Clinico-Epidemiological Profile of Patients with Chronic Kidney Diseases of Unknown Etiology: A Hospital-Based, Cross-Sectional Study from Central India

Abstract Introduction: Chronic kidney disease (CKD) not associated with known risk factors, called CKD of unknown etiology (CKDu), has been reported from several geographically distinct regions across the world. This study reports the clinical and epidemiological profile of patients with CKDu from a new hotspot in central India. Methods: This cross-sectional study describes the sociodemographic, clinical, and laboratory profile of the patients diagnosed with CKDu visiting a tertiary care public hospital in the state of Chhattisgarh in central India between June 2019 and June 2021. CKDu was diagnosed as progressive CKD, minimal proteinuria, absence of hematuria, diabetes, severe hypertension, systemic illness, glomerulonephritis or other urinary tract diseases, and presence of symmetrically contracted kidneyon ultrasound. Results: A total of 166 (3.1%) out of 5365 patients with CKD were diagnosed with CKDu. The mean age was 53.6 ± 11.8 years. The patients were predominantly male (n = 113, 68.1%), belonged to rural areas (n = 147, 88.6%), and were engaged in farming (n = 105, 63.3%). The estimated glomerular filtration rate (eGFR) at presentation was 21.5 ± 15.1 ml/min/1.73m2. Forty-four (26.5%) had stage 3 CKD, 57 (34.3%) had stage4 CKD, and 65 (39.2%) had stage5 CKD. There was an over-representation of CKDu cases in patients with CKD from Gariyaband (36.0%) and Mahasamund (25%) districts of Chhattisgarh and Nuapada (35.0%) and Balangir (30.0%) districts of Odisha. Conclusion: The study suggests clustering of cases of CKDu in certain districts of Orissa and Chhattisgarh.

Oral cancer over six decades: a multivariable analysis of a clinicopathologic retrospective study.

Studies have reported changes in the epidemiological profile of patients with oral cancer in recent decades, especially regarding gender and age. This study aimed to evaluate a historical series of oral malignant lesions prevalence over six decades and define characteristics associated with the occurrence, mainly, of oral squamous cell carcinoma (OSCC). A retrospective review of histopathological records from 1953 to 2019 was conducted in three oral pathology laboratories in South Brazil about age, sex, anatomical site, clinical aspect, and histopathological diagnosis. Descriptive and analytical analyses were performed comparing the histopathological diagnoses with other variables. Multivariable logistic regression was applied to determine the associated predictors of OSCC. Of the 53,065 records available in the institutions, 986 were oral malignant tumors (including all malignant neoplasms), representing 1.86% of all diagnoses. The occurrence of OSCC in the 1960's was 80.0%, decreasing over time reaching the lowest percentage of cases in the 1990's (75.8%) and significantly increasing to 88.7% in the 2010s. Females had a lower chance than males of having OSCC independently of the decade (odds ratio=0.30, p<0.001). This was the same for older individuals compared to those younger than 40 years. No interactions between sex, age, and decade were observed. The number of diagnoses of oral malignant lesions increased over time, and the occurrence of OSCC varied. Older individuals and males had higher chances of having OSCC independently of the decade. Therefore, in this study sample, no changes were observed in the epidemiological profile over the years concerning these predictors.

Clinical and Epidemiological Profile of Patients with Ewing's Sarcoma

Introduction: Understanding that cancer is a pathology that is challenging to detect, treat, and comprehend is what makes the study of cancer so important. The goal of this case study is to show how a 20-year-old woman was affected by a variety of factors and symptoms that, when combined, raised suspicion of Ewing's sarcoma, the second most common primary tumor in children and young adults. Ewing's sarcoma has the characteristics of being an aggressive malignancy originating in the bones.

Study of Clinico- Epidemiological Profile of Patients with Gallbladder Perforation

Background: Gallbladder perforation (GBP) is rare but a potentially fatal disease; its presentation can vary and hence is difficult to diagnose early. It is usually a complication of acute cholecystitis with or without gallstones. Most perforations are subacute, producing a pericholecystic collection. Acute free perforation with biliary peritonitis and chronic perforation with an internal biliary fistula are rare. The fundus of the gallbladder is the most common site of perforation because of its poor blood supply. Material &amp; Methods: This retrospective observational study included all cases of gallbladder perforation that presented to general surgery ward from January 2019 to January 2022. Cases of traumatic gallbladder perforation and gangrenous gall bladder were excluded. The patients were assessed for epidemiological and clinical parameters like age, gender, socio economic status, presenting complaints, history of substance abuse, co- morbidity, hemoglobin, total leucocyte count, renal function tests, liver function tests, history of fever, fever on presentation, pulse, blood pressure and respiratory rate on presentation, type and site of perforation, method of management, diagnostic procedures(ultrasound and contrast CT abdomen findings), duration of hospital stay, and post-operative complications if any were evaluated. Results: This study included 14 patients ( 4 males and 10 females). The mean age of patients was 63.7 years. Gallbladder perforation was most common in the 5th and 6th decade of life. Two Patients had type l perforation and 12 patients had type ll perforation(Neimer’s classification) . Cases were diagnosed on the basis of contrast enhanced CT scan. Patients were managed with carbapenems, intravenous fluids and analgesics . 11(79%) patients were managed conservatively. One patient presented with impending rupture of anterior abdominal wall abscess that was communicating with pericholecystic abscess. Patients on conservative management were managed empirically with Carbapenem antibiotics and recovered well. Two patients underwent cholecystostomy. The mean hospital stay was 11.5 days for conservatively managed group and 18 days for patients who underwent upfront surgery. There was no reported mortality. All patients underwent interval open cholecystectomy after 06 weeks.Mean post operative hospital stay was 4 days in these patients. Each patient was followed up for 06 months in outpatient department and through telecommunication. Conclusion: Gallbladder perforation represents a special diagnostic and surgical challenge. Careful selection and management of patients with broad spectrum antibiotics can help us manage patients conservatively.

The relation between human papillomavirus (HPV) and oropharyngeal cancer: a review.

Oropharyngeal squamous cell carcinomas (OPSCC) represent a major public health challenge. In 2020, the international agency for research on cancer (IARC) recorded 98,421 cases of OPSCC worldwide. Over the past decade, the epidemiological profile of patients with OPSCC has shifted, mainly due to a change in etiological factors. Previously, alcohol and tobacco were considered the primary contributors, but the human papillomavirus (HPV) is now recognized as the leading cause of these tumors. This study aimed to conduct a literature review on the relationship between OPSCC and HPV for the general practitioner. The review examined the primary clinical differences between HPV+ and HPV- OPSCC, their prognosis and treatment. In addition, the various HPV diagnostic methods were analyzed. Although there is a vast amount of literature on HPV, this review is unique in its ability to present the key information in an organized and accessible way and enables healthcare professionals to gain a better understanding of the relationship between HPV and oropharyngeal cancer. This, in turn, can contribute to the prevention of various cancers caused by the HPV virus, including oropharyngeal cancer.

Epidemiological Profile of Patients with Vulvovaginal Candidiasis from a Sexually Transmitted Infection Clinic in Southern Spain.

Epidemiological data on women suffering from vulvovaginal candidiasis and its recurrence are outdated and vague. The aim of this study was to identify the prevalence of women diagnosed with vulvovaginal candidiasis, as well as the epidemiological profile and associated risk factors in the province of Granada (Spain). Data from the Centre for Sexually Transmitted Infections of the Granada province between 2000 and 2018 (N = 438) were used in this study. Associations between sociodemographic and sexual behaviour variables with vulvovaginal candidiasis were analysed using the Chi-square test and bivariate logistic regression. The prevalence of candidiasis was 14.6%. The sociodemographic profile corresponded to a woman aged 25.14 ± 4.8 years on average, who is of Spanish nationality (60.9%), a student (55.7%), in non-active employment (59.7%), with a higher education (56.7%), single (93.5%), and under 30 years of age (79.7%). Variables associated with this diagnosis were the absence of oro-genital contact (OR = 1.99; 95% CI = 0.25-0.74), having a regular partner (OR = 1.99; 95% CI = 1.05-3.75), and age of sexual debut, with the probability increasing by 12% (95% CI = 1.00-1.24) with each year. In this context, vulvovaginal candidiasis infection is common, and its epidemiological profile is contradictory, so our results do not suggest a relevant role of sexual risk behaviours in the diagnosis. Further research is needed to improve the estimates and factors associated with this infection.

Clinical and Epidemiological Profiles of Patients with End Stage Kidney Disease on Dialysis at Dialysis Centers in Addis Ababa, Ethiopia.

End-stage kidney disease is increasing worldwide, primarily in the developing countries. It is affecting mainly the productive age group. Though the prevalence of the disease is increasing in Ethiopia, there are few studies. We therefore sought to describe the clinical and epidemiological characteristics of hemodialysis patients. A descriptive cross-sectional study was conducted at 17 hemodialysis centers in Addis Ababa. Patients who received hemodialysis for at least three months were included in the study. Socio-demographic and clinical data were collected via questionnaires from October to November 2021. This study involved 318 participants with males making up 197 (61.9%) of the participants. Among the total, 248 (78.0%) were in the age group of 20 to 60 years and 155 (48.7%) were unemployed. Hypertension and diabetes mellitus were the major risk factors for end-stage kidney disease. The mean duration of dialysis was 2.26 years. The frequency of dialysis was twice weekly in 150 (47.2%) of the patients and thrice weekly in 138 (43.4%) of the patients. Arterio veneous fistula was used in approximately three-quarters of patients, i.e. 237 (74.5%). The majority of the patients on hemodialysis, 193 (60.7%), pay their own expenses, and 52 (16.4%) of the patients received hemodialysis at public hemodialysis centers. More than two-third of the patients were not in the process of undergoing a kidney transplant due to a variety of factors, including inability to find a donor, 106 (47.7%), being unfit for surgery, 56 (25.2%), and financial constraints, 38 (17.1%). The majority of the patients on dialysis were men, middle-aged, and unemployed. The majority of the patients underwent dialysis in private institutions and were self-funded, and most of them had inadequate dialysis doses. The inability to find a living donor was the most difficult aspect of undergoing kidney transplantation.

CHONDROSARCOMA OF THE PROXIMAL HUMERUS IN A STATE PHILANTHROPIC HOSPITAL

Objective: To analyze the clinical and epidemiological profile of patients with chondrosarcoma of the proximal humerus treated at a Philanthropic Hospital over a period of 5 years. Methods: Documentary, exploratory, descriptive study, conducted by 04 medical records of patients admitted to the Orthopedic Oncology service, with a diagnosis of chondrosarcoma located in the proximal humerus in the period 2014 to 2018. The sex, age, staging, radiology, and surgery performed were investigated. The data obtained were analyzed by descriptive statistics with the aid of the RStudio software. The study was approved by the Research Ethics Committee. Results: All patients were female, and the age ranged from 37 to 50 years. The most frequent symptom was mild local pain, there was no evidence of loss of function at the time of diagnosis. Radiology showed an expansive, lobulated lesion with intermingled calcification. Histology, two cases of grade I chondrosarcoma, one case grade II and one grade III. Enneking I staging 50% and Enneking II in 2 cases. Surgery ranged from local curettage to en bloc resection. Recurrence was null at follow-up time. Conclusion: It is a rare disease with a small number of cases, but it initiates an analysis for further studies in its epidemiology and treatment.

Epidemiological Profile of Patients with Conjuntival Tumors in a Reference Ophthalmological Hospital in Eastern Amazonia

This research aimed to report the prevalence of conjunctival tumors, and their severity between genders, age groups, and to observe the distribution of their laterality in patients of a public health service in Belém do Pará, in the Eastern Amazon, Brazil. Methods: Data were collected,at the Bettina de Souza Ferro University Hospital,in253medical records for the last 12 years (2010 to 2022),regarding conjunctival tumors were removed and examined histopathologically by the Department of Ophthalmology of the Federal University of Pará (UFPA). The incidence of tumorsundergoing excision surgery,the malignancy rate, and margins were investigated, and matched for gender, age, and laterality. Results: Subjects included161men and 92 women, with a mean age of 49.4± 47.2 years. Of these, 193 were benign tumors (76.3%), the most commonly found: 99 Pterygium; followed by 28Epidermoid Carcinomas;24Pyogenic Granulomas;20Intraepithelial Neoplasia and 18squamous papilloma. Among the 31 cases (23.7%) of malignant tumors, the number of male patients was 21 and female patients 10. Most malignant tumors were composed of squamous cell carcinoma (28 cases), followed by melanoma (3 cases). The mean age of patients with malignant tumors removed was 65.0 ± 31 years, as malignant tumors were more prevalent in older patients (chi-square,p&lt;0.001). Conclusions: The most common conjunctival tumors were thepterygium and Epidermoid Carcinomas, more present in male patients, younger and older, respectively.
