Overview
Seborrheic dermatitis
(SD) is a chronic relapsing inflammatory skin disorder mostly confined to areas
where sebaceous glands are prominent, as stated in the Introduction section.
Seborrheic dermatitis
has a global estimated prevalence of 4-5%, with biphasic incidence occurring in infants between the ages of 2 weeks and 12
months, and during adolescence and adulthood. A detailed discussion about the
prevalence of seborrheic dermatitis is in the Epidemiology
section.
The Pathophysiology section
states that seborrheic dermatitis is usually caused by inflammatory responses
(eg T cell depression, complement pathway activation) to Malassezia sp
proliferation in the stratum corneum. The development process of seborrheic
dermatitis in affected patients is in this section.
Discussion of factors that contribute to the
development of seborrheic dermatitis is in the Risk
Factors section.
Seborrheic Dermatitis_Disease SummaryHistory and Physical Examination
The Clinical
Presentation section
describes the clinical features of seborrheic dermatitis depending on the age
group.
The History section and the Physical Examination section
explain the need for further inquiry and thorough examination of patients with
seborrheic dermatitis.
The Screening section
discusses the use of SEborrheic Dermatitis Area and Severity Index (SEDASI) to
assess the severity of facial seborrheic dermatitis.
Diagnosis
Discussions on Wood’s
light, cultures, and skin biopsies in patients with seborrheic dermatitis are
in the Laboratory Tests and Ancillaries
section.
Other conditions that should be ruled out in
the diagnosis of seborrheic dermatitis are listed in the Differential Diagnosis section.
Management
The goals of
pharmacological therapy for seborrheic dermatitis are enumerated in the Principles of Therapy section.
The Pharmacological
Therapy section discusses in
detail therapeutic options in patients with seborrheic dermatitis, such as
antibiotics, antifungals, corticosteroids, or emollients.
The Nonpharmacological
section includes things to educate the patient or caregiver about the
management of seborrheic dermatitis and other therapeutic advice or options.
