Abstract

Introduction: Eczema-like psoriasiform dermatitis has been described as a complication after Brazilian keratin treatment, with the presence of perifollicular scale resembling the outer skin of an onion bulb reported as a characteristic trichoscopic feature. To date, no treatment for this condition has been communicated.

Methods: A retrospective study was conducted on patients diagnosed with eczema-like psoriasiform dermatitis. Clinical and trichoscopic images were analyzed, and the improvement in the scale and the vascular component of patients treated with oral isotretinoin was described.

Results: A total of 132 patients were included. The most frequent trichoscopic findings were perifollicular scale, peripilar desquamation, and interfollicular scale. Most of the 7 patients treated with oral isotretinoin showed a partial improvement in the scale and the vascular component.

Conclusion: The peripilar scale resembling the outer skin of an onion bulb could be used as a marker for this disease. We observed partial response to oral isotretinoin, probably due to the chronic character of this condition secondary to continuous release of formaldehyde, suboptimal doses, or a short treatment time.
