Acrodermatitis continua de Hallopeau y artritis psoriática: reporte de caso / Acrodermatitis continua of Hallopeau and psoriatic arthritis: a case report

Un hombre de 44 años, previamente sano, consultó por poliartralgias asimétricas de características inflamatorias de tres meses de evolución, que comprometió pequeñas y grandes articulaciones. Poco tiempo después desarrolló pústulas periungueales sobre una base eritematosa y degeneración progresiva de la lámina ungueal del pulgar izquierdo, limitando severamente su funcionalidad. Destacó al examen físico la presencia de placas eritemato-escamosas y pustulosas bien delimitadas en el primer y tercer dedo de la mano izquierda con onicodistrofia severa, que fue un aspecto clave para establecer el diagnóstico de acrodermatitis continua de Hallopeau. Adicionalmente, se observaron otros hallazgos del espectro psoriático: parches eritematosos en el escroto, placas eritemato-escamosas con costras hemorrágicas en ambas rodillas y dactilitis. Se confirmó histológicamente el diagnóstico de psoriasis inversa, psoriasis en placas y psoriasis pustular, respectivamente y con los criterios de Classification Criteria for Psoriatic Arthritis, CASPAR, el diagnóstico de artritis psoriática.

A 44-year-old man, previously healthy, consulted for a three-month history of asymmetrical polyarthralgia with inflammatory features involving small and large joints. A few days later, he developed erythema covered by pustules in the nail folds and progressive degeneration of the nail plate of the left thumb, with severe functional limitation. The physical exam showed well-defined erythematous scaly and pustular plaques in the first and third fingers of the left hand, with severe onychodystrophy, which was a key aspect in the diagnosis of acrodermatitis continua of Hallopeau. Other signs of the psoriatic spectrum were observed: erythematous patches of the scrotum, erythematous scaly plaques with hemorrhagic crusts on both knees, and dactylitis. The diagnosis of inverse psoriasis, plaque psoriasis, and pustular psoriasis, respectively, were confirmed by histopathology and, with the CASPAR criteria, psoriatic arthritis. This case is of particular dermatological interest due to the variety of psoriatic manifestations recognized in a single patient and because of the poorly described association between acrodermatitis continua of Hallopeau with psoriatic arthritis.

Escabiasis costrosa imitando una acrodermatitis continua de Hallopeau / Crusted scabies mimicking an acrodermatitis continua of Hallopeau

Resumen Introducción: La escabiasis costrosa (EC) es una variante poco común de sarcoptiosis clásica, altamente contagiosa. Las lesiones poseen una elevada concentración del ácaro Sarcoptes scabiei var hominis, lo que conlleva a un cuadro clínico más extenso que en la escabiasis clásica. Se observa principalmente en pacientes con algún tipo de inmunocompromiso y se relaciona con el síndrome de Down. Caso clínico: Se describe una paciente pediátrica con síndrome de Down quien presentó placas escamosas que afectaron la porción distal de los dedos, asociadas con distrofia ungueal e hiperqueratosis subungueal, por lo que se consideró acrodermatitis continua de Hallopeau como diagnóstico diferencial. Se realizó una biopsia tipo punch con lo que se llegó al diagnóstico de EC. La paciente recibió tratamiento sistémico con ivermectina vía oral y tratamiento tópico con crema hidratante y desonida al 0.1%. Mostró mejoría clínica notoria dos semanas después de finalizar el tratamiento. Conclusiones: La EC es una variante prevalente en pacientes inmunocomprometidos y con síndrome de Down que fácilmente puede confundirse con patologías inflamatorias con alteración de la queratinización epidérmica. Este caso se considera una presentación atípica debido a la afección localizada en los dedos de las manos asociada con distrofia ungueal. El estudio histopatológico fue necesario para realizar el diagnóstico y descartar diagnósticos diferenciales.

Abstract Background: Crusted scabies (CS) is an uncommon, highly contagious, variant of classic scabies. Elevated concentrations of the mite Sarcoptes scabiei var. hominis are found in the skin lesions, which lead to a more exaggerated clinical picture than in classic scabies. This disease is mainly observed in patients with any kind of immunosuppression and relates to Down syndrome. Case report: A pediatric female patient with Down syndrome, who presented a crusty white plaque associated with nail dystrophy and subungual hyperkeratosis affecting the distal portion of the fingers is described. Because of these findings, the diagnosis of acrodermatitis continua of Hallopeau was considered. A punch biopsy was performed, attaining the diagnosis of CS. She received systemic treatment with oral ivermectin, topical treatment with emollient cream and desonide 0.1%. Notorious clinical improvement was observed two weeks after finalizing treatment. Conclusions: CS is variant of scabies prevalent in immunocompromised patients and Down syndrome that can be easily confused with inflammatory pathologies with abnormal epidermal keratinization. This case is considered as an atypical presentation of the disease because of local affection of the fingers and nail dystrophy. The histopathological study was necessary to obtain the diagnosis and rule out differential diagnosis.

Atypical Gianotti-Crosti syndrome

Abstract: We report the case of a male 22-month-old child, with atypical presentation of Gianotti-Crosti syndrome after infection with Epstein-Barr virus.

Acute prurigo simplex in humans caused by pigeon lice

Abstract: Pigeon lice are insects that feed on feathers of these birds; their life cycle includes egg, nymph and adult and they may cause dermatoses in humans. Four persons of the same family, living in an urban area, presented with widespread intensely pruritic erythematous papules. A great number of lice were seen in their house, which moved from a nest of pigeons located on the condenser of the air-conditioning to the dormitory of one of the patients. Even in urban environments, dermatitis caused by parasites of birds is a possibility in cases of acute prurigo simplex. Pigeon lice are possible etiological agents of this kind of skin eruption, although they are often neglected, even by dermatologists.

Gianotti-Crosti syndrome: a case report of a teenager

Abstract Gianotti-Crosti syndrome is a rare disease characterized by acral papular eruption with symmetrical distribution. It is a benign and self-limited disease; the symptoms disappear after two to eight weeks, without recurrences or scars. Skin lesions are usually asymptomatic. Prodrome might occur, suggesting upper respiratory infection, or constitutional symptoms. Diagnosis is eminently clinical, and this disease is associated with viral infections. Due to its rarity and low occurrence in adolescents and adults, we report a case of Gianotti-Crosti syndrome of a teenager.

Acroqueratoelastoidosis: Presentación de un caso caracterizado por ausencia de fibras elásticas / Acrokeratoelastoidosis: presentation of a case characterized by absence of elastic fibers

En el año 1953, Costa describe un cuadro clínico caracterizado por la aparición de pápulas hiperqueratóticas en márgenes laterales de manos y pies, que se asociaba en el examen histológico a cambios epidérmicos (hiperortoqueratosis y acantosis) y particularmente a la reducción y/o fragmentación de fibras elásticas, motivo por el cual esta entidad, considerada actualmente una genodermatosis, recibió el nombre de acroqueratoelastoidosis (AQE). Presentamos un caso en el que destaca la ausencia de fibras elásticas (AU)

In 1953, Costa described a clinical entity characterized by the appearance of hyperkeratotic papules on the lateral margins of the hands and feet, which was associated with epidermal changes (hyperortokeratosis and acanthosis) and to the reduction and /or fragmentation of elastic fibers at histological examination. This entity was named acrokeratoelastoidosis and is currently considered to be a genodermatosis. A case characterized by the absence of elastic fibers is reported.

Acropigmentación reticulada de Dohi: revisión de genodermatosis con pigmentación reticular a partir de un caso clínico / Reticulated acropigmentation of Dohi: review of genodermatosis with reticular pigmentation

La acropigmentación reticulada de Dohi (ARD) o discromía simétrica hereditaria se encuentra dentro de los desórdenes con pigmentación reticular hereditaria. Es una rara entidad que se describió por primera vez en 1929 en Japón por Toyama. Presenta herencia autosómica dominante y el gen responsable se encuentra en el cromosoma 1q21 que codifica para una proteína ARN-adenosina desaminasa (ADAR1 o DSRAD). A pesar, que es un desorden benigno y no reviste complicaciones suele ser estéticamente desfigurante. A continuación, se presenta un caso clínico y se realizará una revisión de la literatura de los otras genodermatosis con pigmentación reticular.

Hereditary symmetric dyschromatosis, also known as reticulated acropigmentation of Dohi is included within a spectrum of reticulate pigment disorders of the skin. It’s a pigmentary disorder characterized by the presence of hypopigmented and hyperpigmented macules giving a reticular pattern in acral areas. It is a rare entity first described in 1929 by Toyama in Japan. It has autosomal dominant inheritance and the responsible gene codes for an RNA adenosine deaminase protein (ADAR1 or dsRAD) on chromosome 1q21. Although, it`s a benign disorder, it can be aesthetically disfiguring. We present a case report and review of the literature of genodermatosis with reticular pigmentation.

Acroangiodermatitis (pseudo-Kaposi's sarcoma) in an HIV sero-positive patient with syphilis and hepatitis C virus coinfection: clinical and dermatopathological features

Acroangiodermatitis is an angioproliferative disease usually related to chronic venous insufficiency, and it is considered a clinical and histological simulator of Kaposi's sarcoma (KS). Immunohistochemistry is the suitable method to differentiate between these two entities. It reveals the following immunostaining profile: immunopositivity with anti-CD34 antibody is restricted to the vascular endothelium in acroangiodermatitis, and diffuse in the KS (endothelial cells and perivascular spindle cells); immunopositivity with anti-HHV-8 only in KS cases. We report the case of an HIV seropositive patient without apparent vascular disease, who presented violaceous and brownish erythematous lesions on the feet, and whose histopathology and immunohistochemistry indicated the diagnosis of acroangiodermatitis.

Acrodermatitis enteropática: caso clínico y revisión de la literatura / Acrodermatitis enteropathica: report of one case

Acrodermatitis enteropathica is an uncommon disease caused by hereditary or acquired zinc deficiency. It is characterized by a triad of alopecia, diarrhea and acraland periorificial dermatitis. It is treated with Zinc supplementation. We report a31-year-old indigent and drug addict female with a cutaneous-mucous syndromecharacteristic of acrodermatitis enteropathica. She had a positive clinical evolutionafter Zinc supplementation.

Acrodermatitis due to zinc deficiency after combined vertical gastroplasty with jejunoileal bypass: case report / Acrodermatite por deficiência de zinco após associação de gastroplastia vertical com derivação jejuno-ileal: relato de caso

CONTEXT: Nutritional complications may occur after bariatric surgery, due to restriction of food intake and impaired digestion or absorption of nutrients. CASE REPORT: After undergoing vertical gastroplasty and jejunoileal bypass, a female patient presented marked weight loss and protein deficiency. Seven months after the bariatric surgery, she presented dermatological features compatible with acrodermatitis enteropathica, as seen from the plasma zinc levels, which were below the reference values (34.4 mg%). The skin lesions improved significantly after 1,000 mg/day of zinc sulfate supplementation for one week. CONCLUSIONS: The patient's evolution shows that the multidisciplinary team involved in surgical treatment of obesity should take nutritional deficiencies into consideration in the differential diagnosis of skin diseases, in order to institute early treatment.

CONTEXTO: Complicações nutricionais podem ocorrer após cirurgia bariátrica, pela restrição no consumo de alimentos e por comprometimento do processo digestivo e absortivo. RELATO DO CASO: Após ter sido submetida a gastroplastia vertical e derivação jejuno-ileal, uma paciente apresentou acentuada perda de peso e desnutrição proteica. Sete meses após a cirurgia bariátrica, manifestou-se quadro dermatológico compatível com acrodermatite enteropática, verificado a partir dos níveis plasmáticos de zinco (34,4 mg%), que se situavam abaixo dos valores de referência. As lesões cutâneas melhoraram significativamente após 1.000 mg/dia de suplementação de sulfato de zinco, por uma semana. CONCLUSÕES: A evolução da paciente mostra que a equipe multiprofissional envolvida no tratamento cirúrgico da obesidade deve considerar as deficiências nutricionais no diagnóstico diferencial das doenças cutâneas, a fim de instituir precocemente o tratamento.

Acroangiodermatite (pseudossarcoma de Kaposi): uma condição raramente reconhecida. Um caso na planta do pé associado a insuficiência venosa crônica / Acroangiodermatitis (pseudo-Kaposi sarcoma): a rarely-recognized condition. A case on the plantar aspect of the foot associated with chronic venous insufficiency

A acroangiodermatite ou pseudossarcoma de Kaposi é entidade angioproliferativa incomum relacionada a insuficiência venosa crônica, fístulas arteriovenosas, membros paralisados, cotos de amputação, síndromes vasculares e condições trombóticas. Apresenta-se, em geral, como máculas, pápulas ou placas purpúricas no dorso dos pés (especialmente hálux) e maléolos. Relatamos um caso de acroangiodermatite afetando a região plantar, por dois anos sem diagnóstico, para o qual a coloração histológica por hematoxilina-eosina e a marcação imuno-histoquímica com CD34 foram decisivas. A paciente tinha insuficiência venosa crônica e a lesão respondeu bem ao uso de bandagens elásticas e repouso com a perna elevada.

Acroangiodermatitis, often known as pseudo-Kaposi sarcoma, is an uncommon angioproliferative entity related to chronic venous insufficiency, arteriovenous fistulae, paralysed limbs, amputation stumps, vascular syndromes and conditions associated with thrombosis. It presents most frequently as purple macules, papules or plaques in the dorsal aspects of the feet, especially the toes, and the malleoli. We report a case of acroangiodermatitis in the plantar aspect of the foot, misdiagnosed for two years, in which haematoxylin-eosin hystopathological stain and immunolabeling with CD34 histochemistry examination were decisive for diagnosis. Patient had chronic venous insufficiency. The lesion responded well to the treatment with a combination of leg elevation and compression.

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.

Acrodermatitis enteropática, una patología al alcance del pediatra / Enteropatic acrodermatitis a patology to reach into of the pediatry

La acrodermatitis enteropática es una entidad rara de la niñez, producida por una deficiencia sérica de los niveles de zinc y caracterizada por lesiones cutaneo-mucosas, alopecia, diarea crónica y modificaciones en el desarrollo pondoestatural y psíquico, de evolución progresiva y con respuesta rápida y sin secuelas al instaurar el tratamiento. Se presenta el caso de una lactante menor con manifestaciones precoces y diagnóstico tardió de acrodermatitis enteropática, corroborado por bajos niveles séricos de zinc biopsia intestinal normal, con remisión rápida de la sintomatología al recibir tratamiento. Se concluyó que el diagnóstico de acrodermatitis enterotópica debe ser planteado en todo niño con lesiones de piel, cuadros enterales, alopecia e infección a repetición y documentado por la historia familiar, niveles séricos de zing, biopsia intestinal y buena respuesta al tratamiento. Además, controlar periódicamente el desarrollo psicomotor y pondoestatural
