Platelet-rich plasma injections and the development of cutaneous sarcoid lesions: A case report

Sarcoidosis is a systemic disorder characterized by noncaseating granulomas that most commonly affect the lungs but may also affect the skin, lymph nodes, joints, and eyes. Skin manifestations of sarcoidosis can occur at sites of cutaneous injections with foreign materials including tattoos, insulin injections, and cosmetic fillers.1 We report the first case of cutaneous sarcoid lesions developing at nonforeign material injection sites in a patient who received platelet-rich plasma (PRP) therapy with no previous history of injections with foreign materials.
