Con tales hallazgos y el antecedente de tener la hija Síndrome de Peutz-Jeghers se emite el mismo diagnóstico en el padre. Como dato de interés se constatan en este individuo múltiples telangiectasias en tórax, cuello y espalda. Los estudios realizados en busca de la causa de estas fueron negativos. Conclusiones: Los antecedentes y los hallazgos encontrados en el paciente permitieron realizar el diagnóstico de Peutz-Jeghers y brindar asesoramiento genético. Se presenta el primer reporte de esta enfermedad asociada a telangiectasias y prolapso de la válvula mitral en la literatura científica(AU)

Introduction: Peutz-Jeghers syndrome is characterized by mucocutaneous hyperpigmentation and gastrointestinal hamartomas that can appear from the stomach to the anus. It has an autosomal dominant inheritance pattern and variable expressiveness. The diagnosis is based on clinical findings and histological appearance of the polyps. No association between this entity and telangiectasias and mitral valve prolapse has been reported so far. Objective: To describe the findings that made it possible to establish the diagnosis of Peutz-Jeghers syndrome in a patient and to provide genetic counseling. Case presentation: Thirty-six-year-old male patient with a history of mitral valve prolapse who attends a clinical genetics consultation with his wife to request genetic counseling due to the fact that their daughter was diagnosed with Peutz-Jeghers Syndrome and they want to know about the risk of having another affected child. On physical examination, a hyperpigmented macule on the lower lip and several of these on the gums were observed. With such findings and the antecedent of having a daughter with Peutz-Jeghers syndrome, the same diagnosis is made in the father. As data of interest, multiple telangiectasias on the thorax, neck and back were found in this individual. The studies carried out to identify the same cause were negative. Conclusions: The history and findings in this patient allowed us to make the diagnosis of Peutz-Jeghers syndrome as well as to provide genetic counselling. The first report of this disease associated with telangiectasias and mitral valve prolapse is presented in the scientific literature(AU)

Malformación vascular oculta: telangiectasia capilar. Reporte de un caso / Occult vascular malformation: capillary telangiectasia. A case report

RESUMEN: La telangiectasia capilar es una alteración vascular caracterizada por una colección de capilares dilatados que carecen de componente muscular y elástico; se presenta entre el parénquima cerebral normal y constituye el 16 a 20% de todas las malformaciones vasculares intracraneales; ocupa el segundo lugar en frecuencia. Su localización más habitual es la protuberancial; es asintomática, excepto cuando se acompaña de otras malformaciones vasculares o son parte de síndromes de tipo vascular. Su diagnóstico, en casi todos los casos se lo efectúa por los hallazgos incidentales de los estudios de imagen realizados por otras causas. Aunque la telangiectasia capilar pasa desapercibida tanto en la tomografía axial computarizada (TAC) como en la resonancia magnética nuclear (RMN) sin contraste, con el gadolinio endovenoso se observa una lesión hiperintensa, irregular, con apariencia de "cepillo", sin definición individual de los vasos. Se presenta el caso de un paciente de 1 año 2 meses de edad, previamente sano, que ingresó con sintomatología de meningoencefalitis y estatus convulsivo. Se realizó los estudios de resonancia magnética simple, contrastada y angiorresonancia, en los cuales se identificó, de manera incidental, telangiectasia capilar protuberancial, visible únicamente en el estudio contrastado. Se realiza una revisión bibliográfica de dicha patología.Palabras claves: telangiectasia capilar, malformaciones vasculares, resonancia magnética.

ABSTRACT: Capillary telangiectasia is defined as a collection of dilated capillary vessels, without muscular and elastic components, situated within otherwise normal brain parenchyma and accounts for 16-20% of all intracranial vascular malformations, representing the second most common one. It is most frequently found in the pons and it has an asymptomatic natural course, except when the lesions are associated with other vascular malformations or are part of a vascular syndrome. Most are diagnosed as incidental findings in imaging studies performed for other causes. Capillary Telangiectasia is invisible in Computed Tomography and Magnetic Resonance without contrast, however, after intravenous administration of Gadolinium, it will present as a hyperintense, irregular, "brush-like" enhancing lesion, without individual definition of the vessels. We describe the case of a 1 year and 2 months old patient, previously healthy, who presented with signs of meningo-encephalitis and epileptic status. A Magnetic Resonance Image with and without contrast and an angioresonance were performed, in which, as an incidental finding, a pontine Capillary Telangiectasia, visible only in contrasted images was found. A bibliographic review of said pathology is presented in this article.Keywords:capillary telangiectasia, vascular malformations, magnetic resonance.

Uso de tartarato de brimonidina para resolução de matting telangiectásico: relato de caso / Use of brimonidine tartrate to resolve telangiectatic matting: case report

Resumo A escleroterapia é, atualmente, o tratamento de escolha para telangiectasias e veias reticulares, apresentando nível de recomendação 1ª pela diretriz europeia para escleroterapia. Os efeitos colaterais mais comuns desse procedimento são a hiperpigmentação e o matting telangiectásico, sendo este último um dos mais temidos em virtude do dano estético e da dificuldade de tratamento. O matting se refere a vasos com diâmetro inferior a 0,2 mm que podem surgir esporadicamente ou em áreas bem definidas, principalmente nos membros inferiores. Este relato apresenta um caso de matting tratado com o uso de tartarato de brimonidina tópico.

Abstract Sclerotherapy is currently the treatment of choice for telangiectasias and reticular veins, with grade 1A recommendation in the European Guideline for sclerotherapy. The most common side effects of this procedure are hyperpigmentation and telangiectatic matting, the second of which provokes great concern because of the esthetic damage and the difficulty of treatment. Matting refers to vessels with a diameter of less than 0.2 mm, which may emerge irregularly or in well-defined areas, especially on the lower limbs. This report presents a case of matting treated with topical Brimonidine Tartrate.

Cutaneous collagenous vasculopathy: light and transmission electron microscopy

Abstract Cutaneous collagenous vasculopathy is a rare acquired idiopathic microangiopathy characterized by progressive development of diffuse asymptomatic telangiectasias and histologically by accumulation of collagen type IV around the affected vessels. It is diagnosed by its clinical history, confirmed by light microscopy with collagen-specific immunostaining. We report a case of a patient with extensive acquired telangiectasias on the left arm, clinically resembling unilateral nevoid telangiectasia. Dilated blood vessels with thickened walls were observed in the dermis. Immunohistochemistry with collagen IV antibodies revealed marked collagen deposition around the vessels, confirming the diagnosis. Transmission electron microscopy observed duplicate and triplicate vascular basal membrane associated with deposition of amorphous material around the membranes.

Spectrum of Novel Hereditary Hemorrhagic Telangiectasia Variants in an Austrian Patient Cohort

OBJECTIVES: Hereditary hemorrhagic telangiectasia (HHT) is a rare autosomal dominant genetic disorder characterized by pathogenic blood vessel development and maintenance. HHT type 1 (HHT1) and type 2 (HHT2) are caused by variants in endoglin (ENG) and activin receptor-like kinase-1 (ACVRL1), respectively. The aim of this study was to identify the spectrum of pathogenic variants in ENG and ACVRL1 in Austrian HHT families. METHODS: In this prospective study, eight Austrian HHT families were screened for variants in ENG and ACVRL1 by polymerase chain reaction amplification and sequencing of DNA isolated from peripheral blood. RESULTS: Heterozygous variants were identified in all families under study. HHT1 was caused by a novel c.816+1G>A splice donor variant, a novel c.1479C>A nonsense (p.Cys493X) variant and a published c.1306C>T nonsense (p.Gln436X) variant in ENG. Variants found in ACVRL1 were novel c.200G>C (p.Arg67Pro) and known c.772G>A (p.Gly258Ser) missense variants in highly conserved residues, a known heterozygous c.100dupT frameshift (p.Cys34Leufs*4) and the known c.1204G>A missense (p.Gly402Ser) and c.1435C>T nonsense (p.Arg479X) variants as causes of HHT2. CONCLUSION: Novel and published variants in ENG (37.5%) and ACVRL1 (62.5%) were exclusively identified as the cause of HHT in an Austrian patient cohort. Identification of novel causative genetics variants should facilitate the development of tailored therapeutical applications in the future treatment of autosomal dominant HHT.

Síndrome de solapamiento: polimiositis-esclerodermia. Presentación de un caso / Polymyosis-Sclerosis Overlap Syndrome. Case report and review of literature

Introducción: en el síndrome de solapamiento o superposición existen simultáneamente manifestaciones clínicas o serológicas de dos o más enfermedades autoinmunes sistémicas. Afectan al 5 por ciento de la población con predominio en mujeres. Presentación del Caso: hombre de 48 años, sin antecedentes patológicos personales. Acude con dolor en ambas manos, inflamación en las articulaciones metacarpo e interfalángicas proximales, bilateral y simétrica, acompañada de rigidez matinal que duraba casi todo el día desde hace 4 meses. Se le diagnostica artritis reumatoidea y se inicia tratamiento que abandonó. Luego aparece un cuadro que es interpretado como un solapamiento por lo que es ingresado con un cuadro clínico florido. En los exámenes de laboratorio: las transaminasas, la creatín fosfoquinasa, el lactato deshidrogenasa, se encontraban elevadas. Por la clínica y los complementarios se diagnosticó Síndrome de Solapamiento de polimiosistis-esclerodermia. Se comenzó tratamiento con inmunosupesores. El paciente evolucionó desfavorablemente y falleció. Discusión: el diagnóstico de este caso se realizó por las manifestaciones clínicas como fascie esclerodérmica, signo de sal y pimienta, fibrosis de predominio distal en ambas manos, telangiectasias peribucales. Los diagnósticos diferenciales son las enfermedades autoinmunes sistémicas cuando se presentan como cuadros únicos. El tratamiento de primera línea y el pronóstico dependen de las enfermedades que se solapen(AU)

Introduction: In the syndrome of overlap or overlap there are simultaneously clinical or serological manifestations of two or more systemic autoimmune diseases. They affect 5 percent of the population with predominance in women. Case Presentation: A 48-year-old man with no personal pathological history. He came with pain in both hands, inflammation in the metacarpal and interphalangeal proximal joints, bilateral and symmetrical, accompanied by morning stiffness that lasted almost all day for 4 months. He was diagnosed with rheumatoid arthritis and started treatment that he abandoned. Then a picture appears that is interpreted as an overlap so it is entered with a florid clinical picture. In laboratory tests: transaminases, creatine phosphokinase, lactate dehydrogenase, were elevated. Clinical and complementary diagnosis of Polymyosis-Sclerosis Overlap Syndrome was diagnosed. Treatment with immunosupers was started. The patient evolved unfavorably and died. Discussion: The diagnosis of this case was made by clinical manifestations such as sclerodermic fascia, salt and pepper sign, predominantly distal fibrosis in both hands, perioral telangiectasias. Differential diagnoses are systemic autoimmune diseases when presented as single frames. First-line treatment and prognosis depend on overlapping diseases(AU)

Glicose como causa e tratamento de necrose cutânea / Glucose as a cause of and treatment for cutaneous necrosis

A escleroterapia continua sendo um dos procedimentos mais executados pelos cirurgiões vasculares brasileiros. O conhecimento das suas complicações é imprescindível para que possamos evitá-las. Os efeitos colaterais graves desse método de tratamento para as telangiectasias dos membros inferiores são raros e frequentemente associados a um erro técnico ou à dosagem injetada. São predominantemente locais, apresentando-se, algumas vezes, como uma situação de difícil resolução. Relatamos um caso de formação de necrose cutânea após escleroterapia química com glicose hipertônica (75%) e sua cicatrização utilizando preparação tópica contendo vaselina e glicose 60%, cujo resultado estético foi satisfatório

Sclerotherapy remains one of the procedures most frequently performed by Brazilian vascular surgeons. Knowledge of its complications is indispensable to enable us to avoid them. The severe side effects of this method of treatment for telangiectasias of the lower limbs are rare and are often associated with technical errors or the dose injected. Complications are predominantly local, but are sometimes difficult to resolve. We report a case of formation of cutaneous necrosis after chemical sclerotherapy using hypertonic glucose (75%), which healed when treated with a topical preparation containing vaseline and 60% glucose, with satisfactory esthetic results

Dermoscopy in the diagnosis of juvenile xanthogranuloma

Abstract: Juvenile xanthogranuloma is the most common form of non-Langerhans cell histiocytosis. It manifests clinically as a red-yellow papule, usually showing spontaneous remission. The diagnosis is based on clinical and histological findings. We report the use of dermoscopy ("setting sun" pattern) as an adjuvant tool in the diagnosis of juvenile xanthogranuloma in a female patient presenting with a 2-month history of a pre-auricular papule.

Proper use of topical corticosteroids

Topical corticosteroids are widely prescribed and used. As interest in the use of corticosteroids grows, people are increasingly exposed to misinformation that causes an excessive fear of side effects. Topical corticosteroids mainly have vasoconstrictive, anti-inflammatory, immunosuppressive, and anti-proliferative effects. Corticosteroids are prescribed based on the patient's age, the site and severity of the lesion, and patient compliance. Adverse reactions include skin atrophy, telangiectasia, hypopigmentation, and steroid-induced acne. To prevent the side effects of topical corticosteroids and to minimize phobias about topical corticosteroids in the future, we suggest providing proper information and education for both physicians and patients about the safety, efficacy, and proper use of topical steroids. In this article, we review basic information about topical corticosteroids and guidelines for their use.
