Lupus pernio following facial trauma.

Cutaneous sarcoidosis may occur at sites of trauma. Two patients are reported in whom lupus pernio developed in the area of facial fractures. Injury may be a factor in the site of development of lupus pernio in some individuals and may have medico-legal implications. Cutaneous sarcoidosis is known to occur at the sites of scars and trauma but lupus pernio has not been widely recognized to show this phenomenon. We report two patients in whom lupus pernio developed at the site of facial trauma.
