Dermoscopic pattern of Kyrles disease

Abstract The clinical diagnosis of Kyrle's disease may sometimes be challenging, due to the clinical similarity of lesions to other pruritic dermatosis. Although the dermoscopy is being increasingly used in daily practice, there is insufficient data in literature describing the dermoscopic patterns of Kyrle's disease, since only one report has been published to date. Herein we report our dermoscopic observation with additional diagnostic tips in a case who was diagnosed with Kyrle's disease histopathologically.

Case for diagnosis. Linear Darier's disease

Abstract: We present a different and rare manifestation of Darier's disease, namely linear Darier's disease. Only a few cases have been described in the literature. The case report is a male patient, 60 years old, presenting brown to red papules and plaques with hyperkeratosis distributed on the abdomen, following Blaschko's lines, with 6 years' evolution. It was a difficult diagnosis until the dermatological workup and biopsy.

Enfermedad de Darier. Presentación en dos hermanos / Darier's disease. Report in two brothers

La enfermedad de Darier (ED) o disqueratosis folicular fue descripta por Darier y White en 1889. Se trata de una alteración de herencia autosómica dominante, causada por la mutación del gen ATP2A2. Esta mutación interfiere en los procesos de diferenciación y crecimiento celular calcio dependientes. El diagnóstico es clínico e histopatológico. Se manifiesta con pápulas y costras eritematoparduzcas queratósicas, pruriginosas, localizadas principalmente en áreas seborreicas, pápulas blanquecinas en mucosa oral y alteraciones ungueales. Presentamos dos casos de ED en dos hermanos y realizamos una revisión de esta entidad (AU)

Darier's disease (DD) or keratosis follicularis was described by Darier and White in 1889. It is an autosomic dominant inheritance disorder caused by mutation of ATP2A2 gene. This mutation interferes in the processes of cell differentiation and calcium dependent growth. Diagnosis is clinical and histopathological. Clinical features include itchy keratotic papules and crusts, located mainly on seborrheic areas, whitish papules on oral mucosa and nail changes. Two cases of DD in two brothers is reported and a review of this entity is made (AU)

Acrokeratosis verruciformis of Hopf - Case report

Abstract: A 54 year-old woman with a 3-year history of rheumatoid arthritis (RA) consulted us because of weight loss, fever and skin eruption. On physical examination, erythematous plaques with a pseudo-vesicular appearance were seen on the back of both shoulders. Histological examination was consistent with rheumatoid neutrophilic dermatosis (RND). After three days of prednisone treatment, the skin eruption resolved. RND is a rare cutaneous manifestation of seropositive RA, characterized by asymptomatic, symmetrical erythematous plaques with a pseudo-vesicular appearance. Histology characteristically reveals a dense, neutrophilic infiltrate with leucocitoclasis but without other signs of vasculitis. Lesions may resolve spontaneously or with RA treatment. This case illustrates an uncommon skin manifestation of active rheumatoid arthritis.

Severe Darier's disease in a psychiatric patient

Darier’s disease is characterized by dense keratotic lesions in the seborrheic areas of the body such as scalp, forehead, nasolabial folds, trunk and inguinal region. It is a rare genodermatosis, an autosomal dominant inherited disease that may be associated with neuropsichiatric disorders. It is caused by ATPA2 gene mutation, presenting cutaneous and dermatologic expressions. Psychiatric symptoms are depression, suicidal attempts, and bipolar affective disorder. We report a case of Darier’s disease in a 48-year-old female patient presenting severe cutaneous and psychiatric manifestations.

Segmental Darier's disease: a presentation of difficult diagnosis

Darier's disease is a rare autosomal dominant genodermatosis. It has an estimated prevalence of 1 in 55,000 to 100,000 individuals, regardless of gender. It is characterized by multiple keratotic papules on the seborrheic areas of the trunk, scalp, forehead and flexures, and the clinical picture is worsened by heat, sun exposure, perspiration and mechanical trauma. Histopathology observed loss of epithelial adhesion and abnormal keratinization. About 10% of cases present in the localized form of the disease. We report a case of segmental Darier's Disease Type I and discuss the main characteristics of this condition.

Do you know this syndrome? / Voce conhece esta sindrome?

Noonan Syndrome is one of the most common genetic syndromes and also an important differential diagnosis in children presenting with syndromic facies similar to Turner's syndrome phenotype. This syndrome is characterized by facial dysmorphism, congenital heart defects, short stature and also a wide phenotypic variation. This article discusses the case of a 10 year-old patient with Noonan syndrome that presented typical facies, cardiac defects (pulmonary dilatation and mitral regurgitation), dental malocclusion, micrognatism, short stature and a certain degree of learning disability.

Síndrome de Noonan é uma das mais frequentes síndromes genéticas e importante diagnóstico diferencial em crianças com fácies sindrômica similar ao fenótipo da síndrome de Turner. É caracterizada por dismorfismo facial, defeitos cardíacos congênitos, baixa estatura e uma ampla variação fenotípica. Esse artigo apresenta um caso de uma paciente de 10 anos de idade com síndrome de Noonan que apresentava fácies tiípica além de defeitos cardíacos (dilatação de artéria pulmonar e insufiência mitral), má oclusão dentária, micrognatismo, baixa estatura e dificuldade de aprendizado.

Enfermedad de Darier diseminada / Extended Darier´s disease

La enfermedad de Darier o disqueratosis folicular es una genodermatosis poco frecuente. Se caracteriza por presentar pápulas hiperqueratósicas aisladas o con tendencia a confluir en áreas seborreicas del tronco y rostro. Pueden estar comprometidas las manos, pliegues, uñas y mucosas. Comienza generalmente en la pubertad y tiene un curso crónico con respuesta variable al tratamiento. Presentamos una paciente de 20 años de edad con enfermedad de Darier, que compromete áreas seborreicas del tronco, rostro y cuero cabelludo, así como miembros superiores e inferiores en casi toda su superficie. Recibió como tratamiento isotretinoína 40 mg/día vía oral durante 16 semanas con excelente respuesta y sin recidiva durante un año de seguimiento.

Enfermedad de Darier / Darier`s Disease

La enfermedad de Darier es un desorden de herencia autosómica dominante infrecuente, caracterizado por pápulas foliculares y perifoliculares y placas queratósicas distribuidas en áreas seborreicas que generalmente se manifiesta en la adolescencia. Se acompaña, además, de compromiso ungueal y mucoso. Se presentan tres pacientes con un cuadro clínico e histopatológico compatible con enfermedad de Darier evaluados en el Servicio de Dermatología del Hospital de Pediatría “Prof. Dr. Juan P. Garrahan”entre agosto de 1988 y mayo de 2010.La media de las edades al momento del diagnóstico fue de 11,33 años. La totalidad de los pacientes presentó manifestaciones cutáneas y ungueales características de la enfermedad. El 100% de los pacientes recibió tratamiento con emolientes, y a dos de ellos se les asoció retinoides tópicos, ácido láctico y/o urea. Es importante recordar que ante un paciente con estas características clínicas debe sospecharse esta enfermedad para poder instaurar un tratamiento oportuno.

Queratose folicular espinulosa decalvante: relato de caso / Keratosis follicularis spinulosa decalvans: case report

A queratose folicular espinulosa decalvante é afecção rara, de transmissão genética ligada ao X ou esporádica, caracterizada por hiperqueratose folicular e alopecia cicatricial. Inicia-se, geralmente, na primeira infância, exacerbando-se na adolescência. As terapias são pouco efetivas, com tratamento frustrante, quando já há alterações predominantemente cicatriciais. Relata-se caso de criança com quadro de alopecia cicatricial intensa, com alterações precoces (já ao nascimento) e rápida evolução para alopecia difusa cicatricial do couro cabeludo, o que tornou o tratamento limitado e desapontador.

Keratosis follicularis spinulosa decalvans is a rare disease, with genetic transmission either X-linked or sporadic, characterized by follicular hyperkeratosis and cicatricial alopecia. The disease usually begins in early childhood exacerbating throughout adolescence. The therapies are somewhat effective, with frustrating treatment when there are changes which are predominantly cicatricial. It is reported a case of child with intense cicatricial alopecia, with precocious changes (already present at birth) that rapidly evolved to diffuse cicatricial alopecia on the scalp, which has limited the treatment, with disappointing results.

Enfermedad de Darier: a propósito de 5 casos / Darier's disease: report of 5 cases

La enfermedad de Darier es un trastorno autonómico dominante que se caracteriza por alteraciones de la queratinización de la epidermis, uñas y mucosas. Es una entidad infrecuente, caracterizada por presentar pápulas queratósicas en áreas seborreicas. En todos los casos existe una mutación en el gen ATP2A2, que mapea en el cromosoma 12q23-24. Se presentan 6 pacientes con enfermedad de Darier y se consideran aspectos clínicos, histopatológicos y terapeúticos de esta entidad.

Caso para diagnóstico / Case for diagnosis

Queratose folicular espinulosa decalvante é uma genodermatose rara, ligada ao X, caracterizada por hiperqueratose folicular, fotofobia, alopécia cicatricial do couro cabeludo e supercílios. Descreve-se o caso de paciente do sexo feminino, de 25 anos, com quadro clínico e evolução típicos desta síndrome.

Keratosis follicularis spinulosa decalvans is a rare X-linked genodermatosis, characterized by follicular hyperkeratosis, photophobia, scarring alopecia of the scalp and eyebrows. A case of a 25 yearold female with typical clinical picture and progression of this syndrome is described.

Erythromelanosis follicularis faciei et colli: relationship with keratosis pilaris.

Erythromelanosis follicularis faciei et colli (EFF) is an unusual condition characterized by the triad of hyperpigmentation, follicular plugging and erythema of face and neck. This is less common in women and familial case reports are few. We report EFF in three siblings in an Indian family, two of whom are females. The possibility of this condition being genetically related to keratosis pilaris as well as being a variant of keratosis rubra pilaris is also discussed.

Enfermedad de Darier segmentaria / Segmental Darier's Disease

Presentamos el caso de una paciente de 34 años de edad, quien consultó por una dermatosis de reciente aparición, con lesiones papulosas de color pardovioláceo y superficie queratósica localizadas en flanco izquierdo. Al realizar el estudio histopatológico se comprueba la sospecha clínica de enfermedad de Darier. Debido a la distribución circunscripta de las lesiones, se la ha denominado enfermedad de Darier segmentaria o localizada. Desde sus primeras descripcines, diferentes autores plantearon una gran dificultad diagnóstica con esta enfermedad, pues no difiere clínica e histopatologicamente den nevo epidérmico disqueratósico acantolítico. La presencia de signos típicos de enfermedad de Darier en pacientes con lesiones localizadas, sumada a descubrimientos recientes en el campo de la genética, donde se revela la presencia de una mutación en el gen ATP2A2 en la piel comprometida por enfermedad de Darier clásica, y no en los pacientes con nevo epidérmico disqueratósico acantolítico, sustentarían el diagnóstico de enfermedad de Darier localizada.

Dermatosis acantolíticas: a propósito de un caso / Acantholytic dermatosis: a case report

Se presenta el caso de una paciente de 64 años que ha tenido episodios recurrentes de lesiones vesiculosas en su extremidad inferior derecha, diagnosticándose una dermatosis acantolítica. Existe un espectro de enfermedades acantolíticas que histopatológicamente presentan acantolisis, pero que no comparten factores genéticos. El diagnóstico clínico puede ser extremadamente difícil y es la suma de herencia, clínica, histopatología y evolución, la que permite llegar a un diagnóstico. Se realiza una reseña de todas estas enfermedades.

We present the case of 64-year-old female patient with recurrent episodes of vesicles in her lower right limb. Histopathological study revealed acantholytic dermatosis. There is a large spectrum of acantholytic dermatosis that histopathologically presents acantholysis but does not share genetic factors. Clinical diagnosis may be extremely difficult and results in the sum of genetics, clinical findings, histopathological studies and evolution. We also present a review of these diseases.

Coexistence of Darier's Disease and Acrokeratosis Verruciformis of Hopf

Darier's disease and acrokeratosis verruciformis are inherited with the same pattern and they share similar clinical properties. We present a patient with both Darier's disease and acrokeratosis verruciformis. The patient had had brownish and skin-colored papules, initially on her face and neck, since the age of 25. Similar lesions had gradually spread to various parts of her body and lastly the dorsal aspect of her feet. On dermatological examination, brownish and skin-colored, 2 to 5 mm, keratotic papules were observed on her face, neck, both axillae, inframammary regions, and dorsa of the hands and feet. The nail examination revealed "V" shaped notches and longitudinal ridges on the fingers of both hands. The biopsy taken from the neck showed typical findings for Darier's disease. The biopsy from the dorsa of the left foot revealed the distinctive structures of acrokeratosis verruciformis. In this article the clinical and histopathological findings of these diseases are reviewed based on our patient.
