Brimonidine-induced unilateral ocular lichen planus: a case report / Líquen plano ocular unilateral induzido por brimonidina: relato de caso

ABSTRACT This report was written to describe a case of unilateral brimonidine-induced conjunctival lichen planus. Because the ophthalmic examination indicated chronic conjunctivitis or drug-induced pseudopemphigoid, the patient underwent thorough ophthalmic and systemic examinations, as well as conjunctival biopsy and direct immunofluorescence studies. A 71-year-old woman with unilateral left eye findings of chronic conjunctivitis was referred to our Ophthalmology Department. The patient reported that chronic conjunctivitis began shortly after she initiated use of topical brimonidine. Ophthalmic examination revealed foreshortening of the inferior fornix and symblepharon. Conjunctival biopsy revealed submucous lymphocytes and shaggy distribution of fibrinogen on direct immunofluorescence; this was suggestive of ocular lichen planus. No other systemic lesions were found that were consistent with the presentation of lichen planus. A good response was observed to topical cyclosporine treatment. To our knowledge, this may be the first report of unilateral ocular lichen planus without systemic findings. The correlation with the initiation of topical brimonidine suggests that this might be the first case of biopsy-confirmed brimonidine-induced ocular lichen planus.

RESUMO Este relato é para descrever um caso de líquen plano conjuntival unilateral induzido por brimonidina. Como o exame oftalmológico indicava conjuntivite crônica ou pseudopenfigóide induzido por medicamento, o paciente foi submetido a exames oftalmológicos e sistémicos completos, além de biópsia conjuntival e estudos de imunofluorescência direta. Uma mulher de 71 anos de idade com achados unilaterais do olho esquerdo de conjuntivite crônica foi encaminhada ao nosso departamento de Oftalmologia. A paciente relatou que a conjuntivite crônica começou logo após o início do uso da brimonidina tópica. O exame oftalmológico revelou encurtamento do fórnice inferior e do symblepharon. A biópsia conjuntival revelou linfócitos submucosos e distribuição felpuda de fibrinogênio na imunofluorescência direta; isso era sugestivo de líquen plano ocular. Não foram encontradas outras lesões sistêmicas compatíveis com a apresentação do líquen plano. Uma boa resposta foi observada no tratamento tópico com ciclosporina. Pelo nosso conhecimento, este pode ser o primeiro relato de líquen plano ocular unilateral sem achados sistêmicos. A correlação com o início da brimonidina tópica sugere que este pode ser o primeiro caso de líquen plano ocular induzido por brimonidina confirmado por biópsia.

Liquen plano blaschkoide facial como expresión de mosaicismo cutáneo, a propósito de un caso / Lichen planus blaschkoide facial as expression of cutaneous mosaicism, on a case by case

El liquen plano es un trastorno inflamatorio adquirido de etiología desconocida que, excepcionalmente, puede presentarse de forma lineal, debido a la predisposición genética de un clon que se produce durante el desarrollo embrionario. El liquen plano lineal o Blaschkoide de localización facial, es aún más infrecuente, y traduce una mutación genética postcigótica, que así como en otras patologías inflamatorias dermatológicas, aumenta la susceptibilidad de los individuos a desarrollarla.

Lichen planus is an acquired inflammatory disorder of unknown etiology that in exceptional cases can occur linearly. This is due to the genetic predisposition of a clone that occurs during embryonic development. Facial localization of the lichen planus is even more infrequent, and translates to a postcigotic genetic mutation. This mutation increases individual susceptibility, just as in other dermatological inflammatory pathologies.

Frontal fibrosing alopecia and lichen planus pigmentosus: diagnosis and therapeutic challenge

Abstract Frontal fibrosing alopecia is a variant of lichen planopilaris with marginal progressive hair loss on the scalp, eyebrows and axillae. We report a case of frontal fibrosing alopecia and lichen planus pigmentosus in a postmenopausal woman, that started with alopecia on the eyebrows and then on the frontoparietal region, with periocular and cervical hyperpigmentation of difficult management. The condition was controlled with systemic corticosteroid therapy and finasteride. Lichen planus pigmentosus is an uncommon variant of lichen planus frequently associated with frontal fibrosing alopecia in darker phototipes. It should be considered in patients affected by scarring alopecia with a pattern of lichen planopilaris and areas of skin hyperpigmentation revealing perifollicular hyperpigmentation refractory to multiple treatments. This case illustrates diagnostic and therapeutic challenge in face of scarring alopecia and perifollicular hyperpigmentation.

Erosive lichen planus: a therapeutic challenge

Abstract Erosive lichen planus is an uncommon variant of lichen planus. Chronic erosions of the soles, accompanied by intense and disabling pain, are some of its most characteristic manifestations. We present the case of a woman who developed oral and plantar erosive lichen planus associated with lichen planus pigmentosus and ungueal lichen planus that were diagnosed after several years. The patient failed to respond to multiple therapies requiring longstanding medication but remained refractory. Knowledge of the treatment options for erosive lichen planus is insufficient. Further research is required to clarify their effectiveness, ideally adopting an evidence-based methodology.

Case for diagnosis

Graham-Little-Piccardi-Lassueur Syndrome is a rare form of Lichen Planus, characterized by the presence of the triad: non-scarring hair loss in the inguinal and axillary regions and follicular spinous or disseminated acuminate papules; typical, cutaneous or mucous LP; and scarring alopecia of the scalp with or without atrophy. These features do not have to be present simultaneously.

Líquen plano hipertrófico disseminado: relevante resposta à acitretina / Disseminated hypertrophic lichen planus: relevant response to acitretin

O líquen plano hipertrófico é uma variante do líquen plano, com pronunciada hiperplasia epidérmica em resposta à coçadura persistente. Clinicamente, caracterizam-se por placas hiperceratósicas, simétricas, de coloração cinza-violácea, com predileção pela região pré-tibial. O prurido intenso, a refratariedade aos tratamentos convencionais e a possibilidade de associação de um carcinoma epidermoide às lesões de longa duração impõem um tratamento eficaz. Os corticoides são considerados o tratamento de primeira linha e podem ser aplicados topicamente ou empregados de forma sistêmica. Outras modalidades terapêuticas propostas são a fototerapia com UVB-NB ou PUVA, imunossupressores e retinoides sistêmicos, com destaque para a acitretina. Relatamos um caso com apresentação clínica exuberante e excelente resposta à acitretin, totalizando um seguimento de nove meses.

Hyperthrofic lichen planus is considered a variant of lichen planus with marked epidermal hyperplasia in response to persistent itch. It is clinically, characterized by symmetric hyperkeratotic plaques, of purplish-grey color, often located in the pretibial region. Intense pruritus, refractoriness to conventional treatments and the possibility of association of the long-term injuries with squamous cell carcinoma requires an effective treatment. The first-line treatment is corticosteroids which can be applied either topically or systemically. Other therapeutic modalities proposed are: NB-UVB phototherapy or PUVA, immunosuppressive drugs and systemic retinoids, notably acitretin. We report a case with exuberant clinical presentation of hyperthrofic lichen planus with excellent response to acitretin after nine months of treatment.

Trasplante capilar en una paciente con alopecia fibrosante frontal asociada con liquen escleroatrófico de vulva / Hair transplantation in a patient with frontal fibrosing alopecia associated with lichen scleroatrophicus vulvae

La alopecia fibrosante frontal (AFF) puede representar una variedad del liquen plano pilaris. Se presenta una paciente con AFF asociada con liquen escleroatrófico de vulva que fue tratada con finasteride (1 mg/día) y aplicaciones tópicas de minoxidil a 2% dos veces al día. Se le efectuaron microtrasplantes de pelo en la zona alopécica frontal y frontoparietal, con resultado excelente que se mantiene 6 años después. Los microtrasplantes capilares pueden ser considerados una alternativa terapéutica no convencional.

Liquen plano anular atrófico / Atrophic annular lichen planus

El liquen plano anular atrófico es una dermatosis poco conocida, descripta por Friedman y Hashimoto en 1991. Se discute si es una variante del liquen plano anular o una forma clínica diferente calsificada dentro del liquen plano. Se caracteriza por placas anulares formadas por pápulas que se van extendiendo hacia la periferia dejando una zona atrófica en el centro. Histológicamente muestra elastolisis en la región central de las lesiones, lo que lo diferencia del liquen plano anular. La evolución generalmente es crónica, y la respuesta al tratamiento es escasa, siendo los corticoides tópicos los más utilizados. Se presenta una paciente con liquen plano anular atrófico, con las características clínicas e histopatológicas descriptas y buena evolución terapéutica.

[Patient with diabetes type 2 and lichen planus cured with SSRI]

Diabetes is one of the great problems in our age and important goal of cure it, is control of blood sugar in order to decreas hyperglycemic long time adverse effects. Also, lichen planus is a chronic skin disease with only conservative and long term treatments that happens many cosmetic and pscychiatric problems in patients. Thus, discover and research about control of diabetes type 2 and lichen planus with modern methods is will of the scientises in all the time. Patient is a 60 years old man with diabetes type 2 and lichen planus that treat with antidiabet oral drugs and routin lichen planus treatments. But blood sugar and lichen planus not controld. Also patient treated with luvox 100mg and xanax 0.5 mg in order to anxity disorder and seen lichen planus and diabet controled. Pay attention to results will hope that stress dependent disorders, such as diabetes type 2 and lichen planus, improved by removing stress factor

Linear lichen planus: a case report

Linear lichen planus [LP] is one of the rare variants of disease. We report here a case of linear LP who presented himself in the out-patient clinic with multiple papules and plaques which coalesced in a linear fashion over the left lower extremities extending from foot to thigh

Liquen plano actínico / Actinic lichen planus

Presentamos cuatro pacientes de raza blanca, oriundos de Sudamérica, con liquen plano actínico. Tres de ellos correspondían a la variedad anular, con lesiones localizadas casi exclusivamente en la cara, caracterizadas por placas ovaladas con bordes sobreelevados y centro de aspecto atrófico. Otro caso mostraba una forma de liquen plano actínico tipo melasma
