We present the case of a 69-year-old Caucasian and non-smoker patient with erythematous, itchy, violaceous lesions on the ankles, wrists, lower legs, forearms and trunk developed within 15 months. Her condition was diagnosed as prurigo and she was treated for a long period of time with antihistaminic drugs, with no resolution of lesions. In October 2008, she presented to a Private Practice of Dermatology in Timisoara. The dermatologist noticed the development of violaceous lesions on her trunk. The patient had similar lesions on the ankles, wrists, lower legs, and forearms for the last eight months. At physical examination many hyperpigmented, 1 to 6 cm, thin plaques were present on the flanks, shoulders, and infra-mammary area. There was no vaginal involvement. This eruption had a good response to topical glucocorticoids, but recurred multiple times after discontinuation of treatment. A biopsy specimen showed some histopathological features of lichen planus.

Colophony is a solid form of resin derived from coniferous trees that has both adhesive and water-resistant properties. For these reasons, this allergen is incorporated into many personal care products, medications, and occupational materials, and is thus commonly implicated in allergic contact dermatitis. Dedicated "dental" allergen series often include colophony, but dermatologists are likely not well-versed on its use in a dental setting.
