Dissecting Celluliti(DSC)

Healed Sinus Tracts

We will continue our week's theme of Dissecting cellulitis (DSC), a rare scarring hair loss condition. It 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 to be extremely helpful.

As seen yesterday, 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 healed sinus tract (arrow).
