What's your diagnosis and differentials?
Scrofuloderma results from the involvement and breakdown of the skin overlying a tuberculous focus, usually a lymph gland but sometimes an infected bone or joint. The most common site is cervical region and less often the axillary, inguinal, epitrochlear and retro-auricular areas.
Clinically the lesions first manifest as blue-red, painless swellings overlying the infected glands and then break down to form undermined irregular ulcers in association with fistula formation. After healing, characteristic puckered scarring marks the site of the infection
