Dermoscopic features seen in telogen effluvium were as follows: peripilar brown halo - 2 (7.4%), focal
atrichia - 17 (63%), pilosebaceous single and double - hair units - 21 (78%) and 5 (18%) patients, respectively.
The main clinical characteristics are hair loss, palmoplantar keratoderma, dystrophic nails,
atrichia or hypotrichosis, and discrete skin hyperpigmentation.
Congenital
atrichia with papular lesions (APL) is a rare disease with autosomal recessive inheritance characterized by scarring alopecia that develops soon after birth.
Particularly any staff exposed to contact of solution due to a leak or spill, and has consequent symptoms such as
atrichia, dermatitis, gastrointestinal system or mucous membrane problems should be evaluated with their complete blood count and basic biochemical observations.
This newly discovered molecular function likely explains why mutations in the hairless gene contribute to the pathogenesis of
atrichia with papular lesions.
In 1954, Damste and prakken (1) followed by lowenthal and Prakken in 1961 (2, 4) used the terminology for patients with
atrichia with multiple follicular keratinous cysts.
