Coexistence of nail lichen planus and lichen planus pigmentosus

Abstract We describe a fifty-six-year old, Afro-descendent female patient showing dystrophy of her twenty nails and hyperchromic, asymptomatic macule on her face. Histopathological examination of the macule showed vacuolization of the basal layer, melanophages in the superficial dermis and lymphoplasmocytic inflammatory infiltrate. Nail biopsy revealed orthokeratotic hyperkeratosis and lichenoid inflammatory infiltrate. Lichen planus pigmentosus is an uncommon variety of lichen planus. It is characterized by typical hyperpigmented macules on the face and neck. Nail changes might be present in 10% of lichen planus cases, but no associations with lichen planus pigmentosus have been described. We report a case of lichen planus in twenty nails associated with lichen planus pigmentosus on the patient's face.

A síndrome de ectrodactilia, displasia ectodérmica e fenda lábio-palatina (EEC) corresponde a uma rara anomalia genética congênita, de herança autossômica dominante, penetrância e expressividade variáveis, associada à mutação no cromossomo 7 ou translocação entre cromossomos 7 e 9, determinada essencialmente pelas características que a denominam. Relata-se caso de paciente de 35 anos, acometido por estigmas sindrômicos, desde o nascimento, com história familiar e sem fenda lábio-palatina.

Ectrodactyly - ectodermal dysplasia - cleft lip/palate syndrome (EEC) is a rare autosomal dominant genetic disorder, with variable expression and penetrance. This congenital disorder is associated either with a mutation in chromosome 7 or with a translocation between chromosomes 7 and 9, reflected primarily in the abnormalities listed in its name. This case report describes a 35-year-old male with syndromic stigmata since birth and no cleft lip/palate. Four relatives are also affected by the condition.
