PAD-UFES-20: a skin lesion dataset composed of patient data and clinical images collected from smartphones

Summary description - The PAD-UFES-20 dataset was collected along with the Dermatological and Surgical Assistance Program (in Portuguese: Programa de Assistência Dermatológica e Cirurgica - PAD) at the Federal University of Espírito Santo (UFES-Brazil), which is a nonprofit program that provides free skin lesion treatment, in particular, to low-income people who cannot afford private treatment. - The dataset consists of 2,298 samples of six different types of skin lesions. Each sample consists of a clinical image and up to 22 clinical features including the patient's age, skin lesion location, Fitzpatrick skin type, and skin lesion diameter. - The skin lesions are: Basal Cell Carcinoma (BCC), Squamous Cell Carcinoma (SCC), Actinic Keratosis (ACK), Seborrheic Keratosis (SEK), Bowen’s disease (BOD), Melanoma (MEL), and Nevus (NEV). As the Bowen’s disease is considered SCC in situ, we clustered them together, which results in six skin lesions in the dataset, three skin cancers (BCC, MEL, and SCC) and three skin disease (ACK, NEV, and SEK) - All BCC, SCC, and MEL are biopsy-proven. The remaining ones may have clinical diagnosis according to a consensus of a group of dermatologists. In total, approximately 58% of the samples in this dataset are biopsy-proven. This information is described in the metadata. - The images present in the dataset have different sizes because they are collected using different smartphone devices. All images are available in .png format. - The metadata associated with each skin lesion is composed of up to 26 features. All features are available in a CSV document in which each line represents a skin lesion and each column a metadata feature. - In total, there are 1,373 patients, 1,641 skin lesions, and 2,298 images present in the dataset. Each image/sample has a reference to the patient and the skin lesion in the metadata. Ethics statement The dataset was collected along with the Dermatological and Surgical Assistance Program (PAD) of the Federal University of Espírito Santo. The program is managed by the Department of Specialized Medicine and was approved by the university ethics committee (nº 500002/478) and the Brazilian government through Plataforma Brasil (nº 4.007.097), the Brazilian agency responsible for research involving human beings. In addition, all data is collected under patient consent and the patient’s privacy is completely preserved. ____ If you have any question do not hesitate to get in touch with us.

### 摘要描述
PAD-UFES-20数据集采集自巴西圣埃斯皮里图联邦大学（Federal University of Espírito Santo, UFES-Brazil）的皮肤与外科援助项目（葡萄牙语原名：Programa de Assistência Dermatológica e Cirurgica，缩写PAD），该项目为非营利性项目，专为无力承担私人诊疗费用的低收入人群提供免费皮肤病变治疗服务。
- 数据集共包含2298个样本，涵盖6类不同的皮肤病变。每个样本由1张临床图像与最多22项临床特征组成，特征包括患者年龄、皮损部位、菲茨帕特里克肤色分型（Fitzpatrick skin type）以及皮损直径。
- 数据集涉及的皮肤病变原本包括7类：基底细胞癌（Basal Cell Carcinoma, BCC）、鳞状细胞癌（Squamous Cell Carcinoma, SCC）、光化性角化病（Actinic Keratosis, ACK）、脂溢性角化病（Seborrheic Keratosis, SEK）、鲍恩病（Bowen’s disease, BOD）、黑色素瘤（Melanoma, MEL）与痣（Nevus, NEV）。由于鲍恩病被视为原位鳞状细胞癌，因此将其与鳞状细胞癌合并，最终数据集内共包含6类皮肤病变：3类皮肤癌（BCC、MEL、SCC）与3类皮肤疾病（ACK、NEV、SEK）。
- 所有BCC、SCC及MEL样本均经活检证实，其余样本可通过皮肤科医师团队的共识获得临床诊断。数据集内约58%的样本经活检证实，该信息已记录于元数据（metadata）中。
- 数据集内的图像因使用不同智能手机设备采集，尺寸各不相同，所有图像均以.png格式存储。
- 每个皮损对应的元数据包含最多26项特征，所有特征存储于逗号分隔值（CSV）文档中，文档每行对应一处皮损，每列对应一项元数据特征。
- 数据集总计包含1373名患者、1641处皮损以及2298张图像，每个图像/样本在元数据中均关联至对应的患者与皮损。
