Purpose: The aetiology of pigmented purpuric dermatoses is unclear. Recent studies speculate about contact sensitivity to play a role in the aetiology of the disease. In most patients, the lesions begin and stay limited on the lower extremities as textile products are in tight contact with the skin. Also, textile dyes can cause contact dermatitis of purpuric type. This study was conducted in order to understand whether the contact sensitivity plays a critical role in the aetiology of pigmented purpuric dermatoses. Materials and methods: Patients with diagnosis of pigmented purpuric dermatoses were included in the study. Patch tests were applied at the back of all patients with textile series (Chemotechnique Diagnostics TF-1000) which have 33 allergens containing textile dyes, material and protectors by IQ Ultra Chamber. Test sites were evaluated at 48, 72, 96. h and on the 7th day according to the criteria of the International Contact Dermatitis Research Group. The evaluation results were recorded in patient files and the results were statistically compared. Results: Eighteen males (60%) and 12 females (40%), a total of 30 patients were included in the study. Schamberg disease in 23 patients (76.7%), lichen aureus in 5 patients (16.7%) and Majocchi disease in 2 patients (6.7%) were described out of total 30 patients. No contact sensitivity was detected in any of the patients. Conclusion: Contact sensitivity to textile dyes was not found as an etiologic factor in our study group.
