Essential oils (EOs) are products with complex chemical composition that are obtained from plants, usually by steam distillation or coldpressing. 1 Allergic contact dermatitis (ACD) from EOs is well-known and has been described for more than 80 different EOs. CASE REPORT A 46-year-old female massage therapist with an atopic background presented at our department with a 7-month history of eczematous lesions in the interdigital folds and dorsum of both hands. Occasionally, lesions were found in the perioral area and also in the axillae in relation to the use of deodorants. The patient had been working at the same aesthetic center for 15 years. One year before, the center had started using Alquimia products (El Taller de Alquimia, Tortellà, Girona, Spain), which included more than 20 EOs. She usually applied a small amount of product to the dorsum of her hands to allow her clients to smell the scent, and afterwards she put her gloves on to carry out the massage. The patient also washed her hands more than 20 times per day. In

BackgroundWhile skin cancer awareness programs have significantly furthered public understanding about the harmful effects of the sun, there is a disparity between photoprotection knowledge and protection practices.ObjectiveTo compare sun exposure habits and photoprotection measures in patients diagnosed with basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma versus controls.MethodsMulticentre case–control observational study carried out by 13 Spanish dermatologists between April 2020 and August 2022. Patients diagnosed with BCC, SCC, or melanoma were considered cases. The control group consisted of individuals with no history of skin cancer.ResultsOf the 254 cases (56.2% female; mean age, 62.67 ± 15.65), 119 (31.2%) had BCC, 62 (16.27%) SCC, and 73 (19.1%) melanoma. The control group consisted of 127 (33.33%) individuals. Avoiding sun exposure between 12:00 and 16:00 was the most commonly used photoprotection measure (habitually/always: 63.1%), followed by the use of sunscreen (habitually/always: 58.9%). Patients with melanoma were less likely to use clothing and shade to avoid sun exposure (p < .05), whereas those with BCC and SCC reported greater use of head coverings (p = .01). BCC and SCC groups reported greater sun exposure 15 years prior, whereas controls reported greater use of sunscreen. However, at the time of this study all groups reported using SPF ≥ 21, and the majority SPF > 50. No differences were observed in photoprotection measures between people with and without a previous history of skin cancer.ConclusionsWe describe differences in photoprotection measures and sun exposure patterns among patients diagnosed with different skin tumor types. Whether these differences may influence the type of tumor each developed will require further investigation.
