Abstract:
Sarcoidosis is a multisystem inflammatory disease manifesting as noncaseating epithelioid cell granulomas. 25 to 30% of individuals with systemic sarcoidosis show variable cutaneous manifestations. A 59-year-old female was seen with reticular purplish-red nodules and plaques on the legs for three months. A skin biopsy of the livedo area revealed non-caseating epithelioid cell granulomas surrounding blood vessels in the dermis. She was diagnosed with sarcoidosis livedo, and cutaneous lesions subsided with oral prednisone. Sarcoidosis livedo (SL) assumes a uncommon livedo reticularis-like presentation. This is the first Chinese patient with SL, and more patients are needed to unveil the unique characters of SL.

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.
