Description this chapter describes dermoscopyThe examination of [skin lesions] with a 'dermatoscope'. This traditionally consists of a magnifier (typically x10), a non-polarised light source, a transparent plate and a liquid medium between the instrument and the skin, and allows inspection of skin lesions unobstructed by skin surface reflections. Modern dermatoscopes dispense with the use of liquid medium and instead use polarised light to cancel out skin surface reflections. of inflammatoryThis glossary term has not yet been described. scalpThis glossary term has not yet been described. diseases

this chapter describes dermoscopy of inflammatory scalp diseases

It has the following subchapters:

Tinea capitis Anna Waskiel Burnat, Lidia Rudnicka
Seborrheic dermatitis Anna Waskiel Burnat, Lidia Rudnicka
Scalp psoriasis Anna Waskiel Burnat, Lidia Rudnicka


Tinea capitisThis glossary term has not yet been described.

The most characteristic trichoscopic findings of tinea capitisThis glossary term has not yet been described. include comma hairs, corkscrew hairs, zigzag hairs and Morse code hairs (1-3) (4, 5) (6-8). Moreover black dots and broken hairs are frequently detected (9). Other trichoscopic features include bent hairs, i-hairs, block hairs and perifollicular/interfollicular scaling (10, 11).

The successful treatment of tinea capitis is characterized by reduction of short broken hairs, corkscrew hairs and zigzag hairs and latter comma hairs and black dots (10).

Moreover, blood extravasations may be observed (12).

Seborrheic Dermatitisalso known as eczema is a group of diseases that results in inflammation of the skin.

In seborrheic dermatitisThis glossary term has not yet been described. thin arborizing vesselsanalytic term is branched vessels; Bright red sharply in focus large or thick diameter vessels dividing into smaller vessels; BCC, atypical vessel and yellowish interfollicular scaling are mainly observed (13).
