Dissecting Cellulitis (DSC)-Healed Sinus Tracts

Dissecting Cellulitis (DSC), is a rare scarring hair loss condition that is characterized by deep inflammation and leads to the formation of draining sinus tracts (especially tunnels that allow pus and inflammation to escape). The diagnosis of DSC in advanced stages is easy as these openings (sinus tracts) can be seen all over the scalp. In early stages, up close exam and use of a dermatoscope can prove extremely helpful.

Early DSC is characterized on dermoscopy by large yellow dots, thin vellus hairs within the area, broken hairs and healing (covered) or open sinus tracts. This picture shows a sinus tract at an earlier stage than the picutre yesterday (panel 4 in our 5 day series). There is inflammation in the skin which gives a red color.
