• SD can manifest in numerous locations, including the scalp, in and behind the ears, or on the face, chest, genitals, axillae, and intergluteal areas.
• Stress is a common trigger for exacerbations of SD.
• Often displaying an annular configuration, SD is frequently mistaken for fungal infection (“ringworm”).
• A flare of SD can be an early sign of Parkinson’s disease or undiagnosed HIV.
• A significant part of the treatment of SD is patient education, not only about the diagnosis and treatment, but also regarding prognosis.
