Dermatological diseases and treatments
Seborrheic dermatitis or eczema
This is a chronic dermatitis which is usually mild and typically affects skin regions with high sebum production and large body folds. There are two forms: infant and adult. Adult seborrheic dermatitis or eczema is probably the most common type of eczema. It usually presents in the form of patches or plaques, which vary from yellowish pink to reddish brown, with greasy flakes. Sometimes small blisters and scabs appear (generally caused by irritation after excessive treatment), usually in areas rich in sebaceous glands. The symptoms of seborrheic dermatitis vary in intensity depending on the patient. Some patients do not present any symptoms, and others experience itching or burning. Seborrheic dermatitis can be difficult to distinguish from other diseases; for instance, when it affects the face it may look like early rosacea. When seborrheic dermatitis affects the scalp it must be distinguished from psoriasis, fungal infections and atopic dermatitis, among others. The treatment chosen will depend on the severity and extension of the lesions and any previous treatments undertaken by the patient.
