ACNE SINUS TRACT
By Gary M. White, MD
A sinus tract is an epithelial-lined tunnel with one opening at the surface of the skin and the other ending blindly. It may form and persist in the setting of acne.
A linear or angular dermal lesion with an opening or pore is characteristic. In contrast to a typical acne cyst, the sinus tract persists. It may periodically fill, become inflamed, drain etc.
Usually, sinus tracts need to be excised.
