“…(9,10) Several studies also found that dermatologists had the best results in the clinical diagnosis of melanoma. (9) Furthermore, accuracy was found to increase with greater professional experience, as was the case in the present study. (2,8,11) The accuracy of participants in determining the histological type of tumours was lower than in determining the presence of a malignancy, as shown in Tables 1 and 2.…”

“…(12) Diagnostic accuracy tends to be lower for SCC, at approximately 36%. (2,3,8,9) The mortality rate of melanoma has made it the focus of increased attention. According to Boiko et al, 75% of general practitioners and 50% of consulting physicians can fail to diagnose a melanoma.…”

Objective: To analyze the accuracy of the clinical examination in the diagnosis of eyelid lesions. Methods: From the observation of thirtyfive photos of benign and malignant eyelid tumors were presented to ophthalmologists, for each picture, it was asked 3 questions: 1) the lesion is malignant or not; 2) if considered malignant, the probably histological type; and 3) the tumor is aggressive or not. The phisicians were divided into 9 groups, according to academic degree (time since graduation and Oculoplastics specialty or not). Answers were compared with the results of the histopathologic study of the surgically resected tumor. Results: In total, one hundred and six ophthalmologists were interviewed. The professional experience influenced the diagnosis of malignancy of the tumor, as the Group 1 (first year residents) had the lowest accuracy (64.5%), with lower estimated agreement (kappa = 0.13), and Group 5 (graduated 5 years ago and with expertise in Oculoplastics) the highest accuracy (77.3%), with better agreement (Kappa = 0.45), and presented the best parameters for other analyzed items. For the histological type diagnosis, accuracy was lower: group 1 had the worst performance, with 51.1% accuracy, while the best was for group 6 (graduated over 5 years and with expertise in Oculoplastics, 77.2% ). As for the criterion of tumor aggressiveness, the results were closer among the different categories. Ophthalmologists trained longer and without expertise in Oculoplastics also showed a low diagnostic accuracy for malignancy and to determine the histological type of tumor. Conclusion: The low accuracy of clinical diagnosis of eyelid tumors in the groups above reinforces the need to improve ophthalmic oncology knowledge in these groups.Keywords: Eyelid neoplasms/diagnosis; Eyelid neoplasms/pathology; Medical oncology; Health knowledge, atitudes, practice RESUMOObjetivo: Analisar a acurácia do exame clínico no diagnóstico de lesões palpebrais. Métodos: A partir da observação de trinta e cinco fotos de tumores palpebrais benignos e malignos que foram apresentadas a médicos oftalmologistas, para cada foto foram feitas 3 perguntas: 1) lesão maligna ou não? 2) se considerado maligno, o provável tipo histológico; e 3) tumor agressivo ou não? Os médicos foram agrupados em 9 grupos, de acordo com a formação profissional (tempo de formação e especialização ou não em Oculoplástica). As respostas foram comparadas com o resultado do exame histopatológico da peça retirada cirurgicamente. Resultados: No total, cento e seis médicos oftalmologistas participaram do estudo. A experiência do profissional influenciou no diagnóstico de malignidade do tumor, já que o grupo 1 (residentes de primeiro ano) apresentou a menor acurácia (64,5%), com menor concordância estimada (Kappa = 0,13), e o grupo 5 (formados há 5 anos e especializados em Oculoplástica) a maior acurácia (77,3%), com melhor concordância (Kappa = 0,45), além de apresentar as melhores medidas para os demais itens avaliados. Para diagnóstico do tipo histológico, a ac...

“…(13,14) Vários estudos demonstram também a maior capacidade do dermatologista no diagnóstico clínico de melanoma. (14) Da mesma forma, a acurácia aumenta conforme o grau de experiência profissional. (5,15,16) O tratamento de tumores palpebrais envolve uma série de fatores que podem influenciar em sua recorrência, como tamanho, localização, doenças associadas e tipo histológico.…”
