Background: Introduction of informatics has facilitated the apparition of lesions affecting the hand responsible of mouse movement. Different cases of contact dermatitis related to the use of personal computers have been published in the last years and two new morphologic patterns within cutaneous pathology affecting hands have been described in direct relationship with professional occupation, named generally “computer fingers” and “computer palms”. Case report: We present a 7‐patient series presenting lesions suggesting contact dermatitis after continued use (min 8 hours/day) of personal computer from a total of 700 patients revised. Patch tests including standard series of the GEIDC, series for plastics and glues and others related to specific details of each patient were performed in all cases. Six of our patients presented lesions in the 2, 3 and 4 fingers of the right hand while the other one was affected in the right hand palm. In our patients, all the epicutaneous tests were negative or without relevance, suggesting a mechanical cause to the occupational dermatitis presented. Comments: Products used in the fabrication of ABS plastics, employed to make personal computers mouse, such as ftalates, cobalt salts and resorcinol monobenzoate have been described as possible allergens. However, concentration of these allergens is too small to ensure a causal relationship. Pressure or an excessive sweating could facilitate these reactions. Wide use of informatics nowadays obliges us to consider those factors in patients presenting chronic dermatoses in their hands. Furthermore, better ergonomics in work places could prevent this kind of occupational dermatitis.
