Scar sarcoidosis: a case report and brief review

Abstract

Scar sarcoidosis refers to lesions of cutaneous sarcoidosis that appear in preexisting scars. This condition may be caused by mechanical trauma such as skin cuts or venipuncture, scars caused by infection such as herpes zoster, and tattoos. We present a case of a 34-year-old man who developed scar sarcoidosis following minor trauma to the left calf. We review the epidemiology, clinical presentations, pathophysiology, and treatment options for scar sarcoidosis.
