Alopecia – Definition

Alopecia refers to hair loss in areas of skin that normally have hair. There are two forms of alopecia: scarring and non-scarring.

Scarring is the loss of hair follicles. This form causes permanent hair loss. The most prevalent forms of scarring alopecia are:

  • Cutaneous lupus erythematous
  • Central centrifugal cicatricial alopecia
  • Fungal kerions

In the case of non-scarring, the hair shaft is gone, but the follicles are still present. It often is reversible. It can also develop into the scarring type. Non-scarring types include:

  • Androgenetic (hereditary) alopecia
  • Telogen effluvium
  • Alopecia areata is an autoimmune process; the cause is not known

Acne – Definition

Acne occurs when the pores of the skin become clogged, inflamed, and sometimes infected. These clogged pores can result in blackheads, whiteheads, or pimples. Acne tends to occur in teenagers, but can also occur in adults.

Acne – Causes

Acne starts in the skin’s sebaceous glands. These glands secrete an oily substance called sebum. The sebum normally travels through a tiny hair follicle from the gland to the skin’s surface. Sometimes the sebum becomes trapped, mixing with dead skin cells and bacteria. This causes clogged pores called comedones.

(Systemic Sclerosis)

Scleroderma – Definition

Scleroderma is a rare disease of the connective tissue. It can cause the tissue in skin, joints, and internal organs to thicken and stiffen. There are three major forms of the disease:

  • Localized scleroderma (also known as morphea) — usually affects only the skin in isolated parts of the body. This form is less serious.
  • Systemic scleroderma — affects widespread areas of skin and/or internal organs, most often the lungs (Certain categories of this form of scleroderma are more serious and can be fatal.)
  • Overlap syndrome — may involve features of scleroderma and features of other autoimmune syndromes
