Abstract
The aim of this study was to determine if there were characteristic trichogram changes
in scalp psoriasis in patients without clinically evident effluvium or alopecia. A
total of 45 patients (17 men and 28 women, aged from 15 to 73 years) with clinically
and histologically confirmed psoriasis vulgaris with scalp involvement were included.
The control group consisted of 60 volunteers (23 males and 37 females aged from 15
to 74 years) with no scalp involvement. Our results from the psoriatic group showed
highly increased proportions of dysplastic hair roots. Median proportion was 50% with
95% confidence interval (CI) for median 30–60%, whereas telogen hair ratio was slightly
increased—median proportion was 16% with 95% CI for median 15–20%. Within the psoriasis
patients’ group no statistically significant correlations were found between the proportion
of dysplastic hairs and the patients’ age, sex, and the intensity and duration of
disease. According to the results of this study, the dysplastic hairs in scalp psoriasis
are statistically significant much more frequently compared with the control group.
Thus, the increased proportion of dysplastic hairs in scalp psoriasis without effluvium
or alopecia might be its characteristic trichogram sign.
