Seborrheic Dermatitis Introduction
Seborrheic dermatitis is a common, chronic, inflammatory disease. It has been proposed that Pityrosporum yeast is the cause. All ages can be affected though the clinical presentation among children differs from that of adults.
For many patients, seborrheic dermatitis is primarily a cosmetic issue. Patients are bothered by facial redness or showers of dandruff on dark colored clothing. For some patients, seborrheic dermatitis is a manifestation of another underlying process. Seborrheic dermatitis has greater severity and is more difficult to control in patients with neurologic disease such as head trauma, spinal cord injury, Parkinson’s disease or stroke. Patients with human immunodeficiency virus (HIV) infection are often afflicted with severe recalcitrant flares.
