Introducción: La acrodermatitis enteropática es una dermatosis nutricional heredada o adquirida por deficiencia de zinc que clínicamente se caracteriza por eritema, escamocostras y erosiones, especialmente en la región perioral, en zonas acras y en la región anogenital. Además de una ingesta oral inadecuada, hay causas secundarias de esta deficiencia nutricional. Objetivo: Referir una dermatosis nutricional secundaria infrecuente en lactante femenina. Presentación de caso: Pequeñita de 6 meses de edad, fototipo III, alimentada con lactancia materna exclusiva, que acude a consulta especializada de dermatología en el hospital William Soler por cuadro clínico de 3 meses de evolución caracterizado por lesiones eritematocostrosas en regiónes acrales y periorificiales. Los padres refirieron lactancia materna exclusiva. Se realizaron complementarios Conclusiones: Las deficiencias de vitaminas y oligoelementos pueden ocasionar un amplio rango de hallazgos mucocutaneos. En el caso presentado diagnosticado como acrodermatitis enteropática adquirida, hay un aporte inadecuado de zinc en la leche materna(AU)

Introduction: Acrodermatitis enteropathica is an inherited or acquired nutritional dermatosis by zinc deficiency that is clinically characterized by erythema, squamous crusts and erosions, especially in the perioral region, in acral areas and in the anogenital region. In addition to inadequate oral intake, there are secondary causes of this nutritional deficiency. Objective: To refer a nutritional dermatosis uncommon in female infants. Case presentation: 6-months-old baby girl, skin phototype III, fed with exclusive breastfeeding whom was attended in the specialized consultation in Dermatology of William Soler Pediatric Hospital due to clinical framework of 3 months of evolution characterized by eritemato crusty lesions in acral and periorifices´ regions. Parents commented on exclusive breastfeeding. There were made complementary blood tests. Conclusions: The deficiencies of vitamins and trace elements may cause a wide range of mucocutaneous findings. In the presented case diagnosed as adquired acrodermatitis enteropathica, there is an inadequate intake of zinc in breast milk(AU)

Acrodermatitis enteropática ampollosa / Bullous Acrodermatitis Enteropathica

La acrodermatitis enteropática (AE) es una genodermatosis autosómica recesiva causada por la mutación del gen responsable de codificar a la proteína transportadora de Zinc (Zn) SLC39A4. A pesar de ser una rara enfermedad es de fácil manejo y gran relevancia clínica. Se caracteriza por la siguiente tríada: dermatitis acral y periorificial, diarrea y alopecia. Comunicamos un caso de presentación atípica en una lactante de 6 meses de edad con lesiones periorificiales y ampollas acrales que resolvió rápidamente con la terapia suplementaria con Zinc (AU)

Enteropathic acrodermatitis is an autosomal recessive genodermatosis caused by the mutation of the gene responsible for encoding the Zinc transporter protein SLC39A4. Despite being a rare disease, it is easy to manage and of great clinical relevance. It is characterized by the following triad: acral and periorificial dermatitis, diarrhea and alopecia. We report a case of atypical presentation in an almost 6-month-old infant with periorificial lesions and acral blisters that quickly resolved with supplemental Zinc therapy (AU)

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.

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.

Analysis of SLC39A4 gene mutation in a patient with acrodermatitis enteropathica / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To detect pathogenic mutation of the SLC39A4 gene in a male patient with acrodermatitis enteropathica (AE).</p><p><b>METHODS</b>Peripheral venous blood sample and clinical data from the patient and his parents were collected. One hundred unrelated healthy individuals were recruited as controls. All coding exons and flanking exon-intron sequences of the SLC39A4 gene were analyzed by PCR and direct sequencing.</p><p><b>RESULTS</b>The results revealed that the patient and his mother have both carried a novel frame-shift mutation c.1110InsG (p.Gly370GlyfsX47 to TGA) in exon 6. A novel nonsense mutation c.958C to T (p.Q320X) in exon 5 was also detected in the patient and his father and grandmother. This novel mutation was not detected in the unaffected family members and 100 unrelated healthy controls.</p><p><b>CONCLUSION</b>The novel frame-shift mutation c.1110InsG (p.Gly370GlyfsX47 to TGA) derived from the mother and nonsense mutation c.958C to T (p.Q320X) of the SLC39A4 gene derived from the father may underlie the disease in the patient.</p>

Acquired acrodermatitis enteropathica caused by zinc deficiency in a heavy drinker: A case report

Acrodematitis enteropathica is an uncommon disease due to zinc deficiency which is characterized by perioral and acral dermatitis, alopecia, and diarrhea. This disease typically presents in infants, either due to an autosomal recessive genetic disorder or after cessation of breastfeeding. Acquired adult-onset acrodermatitis enteropathica has rarely been reported so far. We report a case of a 38-year-old man who had a history of chronic alcohol intake and presented with severe acrodermatitis enteropathica. The patient was successfully managed with zinc supplement and supportive care.

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.

Manifestaciones dermatológicas de fibrosis quística en un lactante: acrodermatitis enteropática símil y pelo gris / Cutaneous manifestations of cystic fibrosis in an infant: acrodermatitis enteropathica and gray hair

Introducción: Las manifestaciones dermatológicas en el momento del diagnóstico de fibrosis quística son infrecuentes. Objetivo: Describir el caso de una lactante con una presentación dermatológica no habitual de fibrosis quística. Caso Clínico: Lactante que a los 2 meses de edad presenta un mal incremento pondoestatural. A los 4 meses presenta exantema cutáneo, edema y pelo gris. Dentro de su estudio se evidencia hipoproteinemia y anemia, y se confirma el diagnóstico de fibrosis quística mediante el estudio genético. Las alteraciones dermatológicas se revirtieron completamente tras la instauración de la terapia de reemplazo con enzimas pancreáticas. Este es el segundo caso reportado de pelo gris en niños con esta enfermedad. Conclusión: En niños con malnutrición que desarrollan alteraciones de la piel y fanéreos debemos sospechar enfermedades metabólicas como fibrosis quística.

Introduction: Cutaneous manifestations at the time of CF diagnosis are rare. Objective: To describe the case of an infant with an unusual cutaneous presentation of cystic fibrosis. Case report: The case is presented of an infant with delayed physical growth at two months, and at the age of four months, presented with a skin rash and gray hair. Tests revealed the presence of hypoproteinemia and anemia, with the diagnosis of Cystic Fibrosis being confirmed by genetic testing. The rash was completely resolved after pancreatic enzyme replacement therapy. This is the second gray hair case reported in children with this disease. Conclusion Metabolic diseases such as cystic fibrosis should be suspected in malnourished children who develop skin disorders.

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.
