Frontal Fibrosing Alopecia Associated with Lichen Planus Pigmentosus: Not Only in Dark Phototypes

Abstract

The association between frontal fibrosing alopecia and lichen planus pigmetosus was first described in African women. Later, most reports about this association involved dark-skinned patients. Here, we describe 5 cases of frontal fibrosing alopecia associated with lichen planus pigmentosus in light-skinned women from Argentina. Our communication highlights the strength of both entities’ association also in lower Fitzpatrick phototypes.

Multiple Clinical Manifestations of Lichenoid Spectrum: A Patient with Frontal Fibrosing Alopecia, Lichen Planus Pigmentosus, and Nail Lichen Planus

“…The coexistence of two diseases is frequently described in women with dark-skin phenotypes (Fitzpatrick IV, V). However, a recent case and case series and our patient demonstrate that light-skin phenotype may also be affected (Fitzpatrick II, III) [6, 8]. The etiology of both diseases is not clear.…”

“…The association of FFA and LPP was first reported in 2013 by Dlova et al [5]. Since then several cases/case series have been reported in recent years [6-8]. The coexistence of two diseases is frequently described in women with dark-skin phenotypes (Fitzpatrick IV, V).…”

“…Although increasing number of reports of patients with FFA and LPP are published in the last decade [5, 6], data are still limited and new clinical features of this coexistence continue to be defined. Herein, we report a patient with multiple manifestations of lichenoid spectrum, with clinical, histological, and dermoscopic findings.…”
