Trichoscopy and seborrheic dermatitis of the scalp

Argir Argirov, Ilko Bakardziev


Seborrheic dermatitis (SD) is a common chronic form of dermatitis that mainly affects the scalp and the face. Different age groups can be affected as well. The cause of seborrheic dermatitis is not completely understood and it is still debated. There are many diseases in the differential diagnosis of SD which should be considered for the correct diagnosis and the most appropriate treatment option.

Dermoscopy of the scalp (thrichoscopy) is a modern option used in the dermatological practice based on the easy performance and effectiveness. The characteristic trichoscopical features in seborrheic dermatitis on the scalp (SDS) are yellowish desquamation and thin arborizing vessels, which can help for it to be distinguished from socially significant skin diseases such as psoriasis.
