ABSTRACT

Introducción: el nevus azul celular es una tumoración melanocítica dérmica benigna. En ocasiones, puede ser falsamente diagnosticada como lesiones malignas, entre ellas, el melanoma. Caso clínico: se trata de una mujer de 37 años que presentó una masa parotídea izquierda de cuatro meses de evolución correspondiente con un nevus azul celular. Discusión: la región de la cabeza y cuello es la tercera en frecuencia, tras la sacrococcígea y las extremidades. Ante una tumoración melanocítica, es importante la confirmación diagnóstica, debido a las similitudes, tanto clínicas como anatomopatológicas, del nevus azul celular con el melanoma maligno. Conclusiones: es muy importante el diagnóstico diferencial correcto, para lo cual es de ayuda el uso de las tinciones inmunohistoquímicas. El tratamiento de esta tumoración es la exéresis quirúrgica con márgenes, esto presenta un comportamiento benigno y baja tasa de recidiva.


Introduction: Cellular blue nevi is a benign dermal melanocytic tumor. Occasionally, it can be falsely diagnosed as malignant lesions, including melanoma. Clinical case: This is a 37-year-old woman who presented with a left parotid mass of four months of evolution, corresponding with a cellular blue nevi. Discussion: The region of the head and neck is the third in frequency, after the sacrococcygeal and the extremities. During the study of a melanocytic tumor, diagnostic confirmation with a biopsy is important, due to the similarities, both clinical and pathological, of cellular blue nevi with malignant melanoma. Conclusions: the correct differential diagnosis is very important, for which immunohistochemical study is helpful. The treatment of this tumor is the surgical excision with margins, presenting benign behaviour and low recurrence rate.

ABSTRACT

Los nevi azules son proliferaciones melanocíticas dendríticas benignas a nivel dérmico, congénitos o adquiridos, debido a un defecto migratorio embrionario de melanocitos a partir de la cresta neural. Se manifiestan clásicamente como una pápula, nódulo o placa de color azul o azul-gris. Muchos subtipos histológicos se han descrito, siendo los más comunes el nevus azul común, nevus azul celular y nevus azul combinado. Las formas esporádicas incluyen al nevus azul lineal, eruptivo, agminado y con satelitosis. La dermatoscopía característica muestra un patrón de pigmentación homogéneo monocromático azul o azul-grisáceo, con ausencia de otras estructuras. Sin embargo, se han descrito también patrones de pigmentación dicromáticos y multicromáticos, además de estructuras tales como red de pigmento, puntos, glóbulos, proyecciones radiadas, pseudópodos, áreas cicatriciales blanquecinas, patrón vascular y rosetas. El diagnóstico diferencial de los nevi azules incluye lesiones melanocíticas y no melanocíticas, benignas y malignas, destacando entre ellas el melanoma. Se presenta el caso de un paciente de sexo masculino de 30 años, portador de un nevus azul celular con cambios de rápida evolución, con desarrollo de lesiones satélites y un aspecto dermatoscópico sugerente de malignidad, simulando un melanoma.


Blue nevi are benign, congenital, or acquired, dermal dendritic melanocytic proliferations due to an embryonic migratory defect of melanocytes starting from the neural crest. They classically manifest as a blue or blue-gray papule, nodule, or plaque. Many histological subtypes have been described, including common blue nevus, cellular blue nevus and combined blue nevus. Sporadic forms include linear blue nevus, eruptive, agminate and with satellitosis. Characteristic dermoscopy shows a homogeneous monochromatic blue or steel-blue pigmentation pattern, with the absence of other structures. However, dichromatic and multichromatic pigmentation patterns have also been described, in addition to structures such as pigment network, dots, globules, streaks, pseudopods, whitish scar areas, vascular pattern and rosettes. Differential diagnosis of blue nevi includes melanocytic and non-melanocytic, benign and malignant lesions, most notably melanoma. The case of a 30-year-old male patient is presented, with a cellular blue nevus with rapidly evolving changes, with development of satellite lesions and a dermoscopic appearance suggestive of malignancy, mimicking melanoma.

ABSTRACT

RESUMEN El síndrome de Blue Rubber Bled Nevus se caracteriza por múltiples malformaciones cutáneas, asociadas con malformaciones menores en órganos internos, (comúnmente afectan los órganos del sistema digestivo y el sistema nervioso central). A nivel mundial, se afirma que hay cerca de 1 a 2 millones de individuos afectados por este síndrome, y se cree que incide en 1 de cada 6000. En recién nacidos la incidencia se ha calculado en menos de 1 caso por 100 000 persona/año. Se presentó un caso de una paciente femenina de 8 años de edad, con antecedentes de hemangiomas múltiples de color azul violáceo, distribuidos por toda la superficie corporal, de diferentes diámetros. Algunos protruyen y depresibles al tacto. Presentaba ptosis palpebral y movimientos torpes de los cuatro miembros, epilepsia y afectaciones del neurodesarrollo el cual corresponde con una edad cronológica de 11 meses. Mostraba una disminución importante de la visión. Presencia de pie valgo a predominio derecho. Apareció anemia leve por déficit de hierro, inmunoglobulina C3 y C4, la química sanguínea al límite de lo normal. La resonancia magnética nuclear mostró importantes signos de atrofia cortical, más acentuados en región temporal derecha. Son entidades de muy escasa presentación y en la provincia de Matanzas es el único caso con este diagnóstico, por lo que constituyó el motivo para la presentación del caso.


ABSTRACT The syndrome of Blue Rubber Bled Nevus is characterized by multiple skin malformations, associated to minor malformations in internal organs (it commonly affects the organs of the digestive system and the central nervous system). It is affirmed that around 1 to 2 millions of individuals are affected by this syndrome worldwide, and it is believed that it has incidence on 1 of each 6000 persons. In newborns the incidence has been calculated in less than 1 case per 100 000 persons/year. The authors presented the case of a female patient, aged 8 years, with antecedents of purplish-blue multiple hemangiomas of different diameters, distributed all over the surface if the body. Several of them are protruding and depressible to the touch. She presented eyelid ptosis and slow movements of the four limbs, epilepsy, and neurodevelopment affectations corresponding to a chronological age of 11 months. She showed an important decrease of the vision. The study showed a slight iron-deficiency anemia, immunoglobulin C3 and C4, blood chemistry at the normal limit. The magnetic resonance imaging showed important signs of cortical atrophy, stronger in the right temporal region. These are entities of scarce presentation and it is the only case with this diagnosis found in the province of Matanzas; that motivated this case presentation.

ABSTRACT

El melanoma tipo animal o equino, es una variante infrecuente de melanoma con pronóstico incierto. Su nombre se debe a las similitudes histológicas con una neoplasia melanocítica presente en caballos tordillos ancianos. Clínicamente se presenta como una lesión nodular o una placa, con pigmentación intensa, pardo-azulada o negra. Histológicamente presenta principalmente una localización dérmica, observándose una proliferación profunda de células elongadas o redondeadas con moderada atipía ybaja tasa mitótica. Presentamos el caso de un paciente de sexo masculino de 31 años de edad, HIV +, con diagnóstico de melanoma tipo animal...

ABSTRACT

Blue rubber bleb nevus syndrome (BRBNS) is a rare disorder characterized by cutaneous and gastrointestinal (GI) venous malformations. The treatment of BRBNS is primarily supportive and ablative. Ablative therapy involves endoscopic or surgical treatment of GI venous malformations. We describe a 20-year-old woman who had multiple venous malformations all over the GI tract as well as cutaneous lesions. She had suffered from several episodes of melena, chronic anemia and fatigue for 10 years, which were treated temporarily by iron supplementation and blood transfusion. The endoscopic examination of the GI tract and total colonoscopy revealed multiple bluish sessile and polypoid venous malformations 2-3 cm in size throughout the GI tract. Argon plasma coagulation (APC) and polypectomy was done for all gastric and colonic lesions, respectively. Ileoscopy showed a large wide base vascular polypoid lesion at about 70 cm from the ileocecal valve with active bleeding; this was removed by snare polypectomy. One week later, she was discharged in good condition. At about 6 months' follow up she did not report any bleeding attack. Endoscopic polypectomy can be useful in patients with large and polypoid lesions of BRBNs which are not controlled with supportive therapy. Further experience is needed to evaluate the risks versus benefits of this approach.

ABSTRACT

Blue rubber bleb nevus syndrome is a rare disorder that is characterized by multiple recurrent vascular malformations, such as hemangioma, and these primarily involve the skin and the gastrointestinal tract. It may also involve the brain, liver, lungs, and skeletal muscles. A 14-year-old female visited our hospital with a chief complaint of dizziness; upon examination, we found multiple recurrent hemangiomas on the skin and gastrointestinal tract. We were able to diagnose her as suffering from blue rubber bleb nevus syndrome and we treated her with methylprednisolone (2 mg/kg/day for 1 month and 1 mg/kg/day for additional 3 months). We report on this case along with a review of the literature.

ABSTRACT

The case of a patient with blue rubber bleb nevus syndrome who is infected by acquired immunodeficiency syndrome virus due to multiple blood transfusions is presented. This case shows that although it is a rare systemic disorder, blue rubber bleb nevus syndrome has to be considered in the differential diagnosis of chronic anemia or gastrointestinal bleeding. Patients should be investigated by endoscopy, which is the most reliable method for detecting these lesions. The patient underwent gastroscopy and enteroscopy via enterotomy with identification of all lesions. Minimal resection of the larger lesions and string-purse suture of the smaller ones involving all the layers of the intestine were performed. The string-purse suture of the lesions detected by enteroscopy proved to be an effective technique for handling these lesions, avoiding extensive intestinal resection and stopping the bleeding. Effective management of these patients demands aggressive treatment and should be initiated as soon as possible to avoid risks involved in blood transfusions, as occurred in this case

ABSTRACT

The blue rubber nevus syndrome consists of multiple venous malformations in the skin and gastrointestinal tract associated with intestinal hemorrhage and iron deficiency anemia. Other organs may be involved. The causes of this syndrome are unknown. Its most common presentation is in the form of sporadic cases, but dominant autosomal inheritance has been described. It is a condition that affects both sexes equally, and its occurrence is rare in the black race. We present a case of this syndrome diagnosed in a 11-year-old patient. He had severe anemia and a venous swelling on the trunk. Similar lesions were found in the stomach, bowel, and on his foot. We emphasize the main clinical aspects: intestine, eyes, nasopharynx, parotids, lungs, liver, spleen, heart, brain, pleura, peritoneum, pericardium, skeletal muscles, bladder, and penis lesions, systemic complications that may occur to these patients which are thrombosis and calcification, as well as consumptive coagulopathy and thrombocytopenia that may occur within the nevi.

ABSTRACT

Objetivo. Presentar un caso de sangrado intestinal por un síndrome de nevo azul en burbuja de goma(NABG). Caso: Mujer de 28 años que desde los siete años de edad padeció sangrado intestinal crónico. Recibió múltiples tratamiento con hierro oral y parental y cuatro transfusiones a lo largo de 21 años de evolución. Se presentó con anemia microcítica (HB = hemoglobina de 7.8 g/dL) con deficiencia de hierro y tumoraciones cutáneas en lengua, mano derecha y pies. Una biopsia cutánea mostró un hemangioma cavenoso. La presencia de múltiples tumoraciones intestinales por serie gastroduodenal, endoscopía y colonoscopía, permitieron el diagnóstico. El tratamiento con hierro oral aumentó los niveles de HB. Conclusión. Lo raro del síndrome y hasta donde sabemos el que no se haya informado previamente en México, probablemente llevaron a que la paciente estuviera 21 años sin diagnosticar y sometida a terapias peligrosas, pese a que el diagnóstico no era difícil
