Contact Hypersensitivity as a Murine Model of Allergic Contact Dermatitis

Depigmented contact dermatitis due to incense
Abstract:
A 63-year-old male school teacher with itchy depigmented macules on his left dorsum manus, left shoulder and abdomen presented at our clinic on 8 July 1986. He had practiced the incense ceremony for about 15 years, and had burnt several incenses and sandalwood. 48 h closed patch testing revealed perfume in the incenses was the cause. We assumed that perfume in the incense was volatized in air when incense was burnt; skin surface contact occurred with airborne particle, which dissolved in sebum; thus allergic contact dermatitis accompanied by depigmentation might arise.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
