Insights

Trichoscopy effectively diagnoses tinea capitis (TC) and alopecia areata (AA). Key differences include broken hairs in TC and yellow dots in AA, aiding differential diagnosis.

Area of Science:

  • Dermatology
  • Trichology

Background:

  • Trichoscopy, or hair and scalp dermatoscopy, is crucial for diagnosing hair and scalp conditions.
  • Differentiating between tinea capitis (TC) and alopecia areata (AA) can be challenging.

Purpose of the Study:

  • To identify specific trichoscopic features for diagnosing tinea capitis (TC).
  • To compare trichoscopic findings in TC with those in alopecia areata (AA).

Main Methods:

  • A study involving 15 children with TC and 10 children with AA.
  • Scalp examinations were conducted using a digital dermatoscope at 20X and 40X magnification.

Main Results:

  • All TC patients exhibited broken and dystrophic hairs, along with corkscrew hairs, comma hairs, and black dots.
  • Alopecia areata (AA) patients presented with yellow dots, exclamation mark hairs, and vellus hair.

Conclusions:

  • Distinct trichoscopic features differentiate TC (broken hairs, corkscrew hairs, comma hairs, black dots) from AA (yellow dots, exclamation mark hairs, vellus hair).
  • Further research with larger cohorts is necessary to solidify these findings for differential diagnosis.

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Accessory Structures of the Skin: Hair Growth and Types

Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...
