Abstract:
Lichen planus (LP) is a relatively common papulosquamous disorder that is characterized by pruritic, polygonal papules in a characteristic distribution. We present a case of a 71-year-old man with erythroderma, who was ultimately diagnosed with severe, generalized LP. Treatment of severe LP is challenging, and there are few, robust, clinical trials in the literature to guide the selection of appropriate treatment. We discuss the treatment options for generalized LP and the evidence in support of these agents.

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.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
