FLUO-SC: a fluorescence image dataset of skin lesions collected from smartphones

Dataset Summary

The Fluorescence Skin Cancer (FLUO-SC) dataset was developed over approximately one year, resulting in 1,563 new samples of clinical images (CLI), captured under natural white light conditions, and 1,563 fluorescence (FLUO) samples. The fluorescence images represent endogenous, label-free autofluorescence acquired using the LINCE device (MMO, São Carlos, Brazil), provided by the Institute of Physics of the University of São Paulo (IFUSP).

The dataset collection was conducted as part of the Dermatological and Surgical Assistance Program (PAD, in Portuguese: Programa de Assistência Dermatológica e Cirúrgica), a nonprofit program at the Federal University of Espírito Santo (UFES, Brazil). The PAD program focuses on providing free treatment for skin lesions, particularly benefiting low-income individuals in rural areas.

The dataset encompasses images of six distinct skin lesion categories:

- Basal Cell Carcinoma (BCC), Squamous Cell Carcinoma (SCC), Melanoma (MEL) (biopsy-proven skin cancers);
- Actinic Keratosis (ACK), Seborrheic Keratosis (SEK), and Nevus (NEV) (non-cancerous skin diseases).

The images in the dataset vary in dimensions due to the use of different smartphone devices during acquisition. All images are provided in .jpg format.

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.

数据集概述

荧光皮肤癌（Fluorescence Skin Cancer, FLUO-SC）数据集历经约一年时间开发完成，共计获取1563幅自然光线下拍摄的临床图像（Clinical Images, CLI）样本，以及1563幅荧光（Fluorescence, FLUO）样本。该荧光图像为使用巴西圣卡洛斯MMO公司LINCE设备采集的内源性无标记自发荧光图像，由圣保罗大学物理研究所（Instituto de Física da Universidade de São Paulo, IFUSP）提供。

本数据集的采集工作是巴西圣埃斯皮里图联邦大学（Universidade Federal do Espírito Santo, UFES）旗下非营利项目——皮肤与外科救助计划（葡萄牙语全称：Programa de Assistência Dermatológica e Cirúrgica, 简称PAD）的一部分。该PAD项目致力于为皮肤病变患者提供免费治疗，尤其惠及农村地区的低收入群体。

本数据集涵盖六大类皮肤病变图像：
- 基底细胞癌（Basal Cell Carcinoma, BCC）、鳞状细胞癌（Squamous Cell Carcinoma, SCC）、黑色素瘤（Melanoma, MEL）：均为经活检证实的皮肤癌；
- 光化性角化病（Actinic Keratosis, ACK）、脂溢性角化病（Seborrheic Keratosis, SEK）以及痣（Nevus, NEV）：均为非癌性皮肤疾病。

由于采集过程中使用了不同的智能手机设备，数据集中的图像尺寸各不相同，所有图像均以.jpg格式存储。

伦理声明

本数据集的采集工作依托圣埃斯皮里图联邦大学皮肤与外科救助计划（PAD）开展。该项目由专科医学部负责管理，已通过该校伦理委员会（编号：500002/478）以及巴西负责人类受试者研究的官方机构Plataforma Brasil（编号：4.007.097）的审批。此外，所有数据均在获得患者知情同意后采集，且严格保护患者隐私。
