ABSTRACT
Resumen La facomatosis pigmentovascular es un síndrome congénito muy poco frecuente, caracterizado por la presentación simultánea de una malformación vascular capilar y una lesión cutánea pigmentaria, con o sin compromiso extracutáneo. Se presenta el caso de una adolescente con epilepsia que cursa con crisis mioclónicas focales no controladas por un tratamiento farmacológico irregular, y que muestra además lesiones cutáneas compatibles con nevus flammeus y melanosis dérmica, ocular y palatina, presentes desde el nacimiento. Se trata del primer reporte en el país, de un síndrome neurocutáneo poco frecuente y de su asociación clínica con epilepsia, resaltándose además la importancia de una evaluación integral de esta entidad.
Summary Phacomatosis pigmentovascularis is a rare congenital syndrome, characterized by the simultaneous presentation of a capillary vascular malformation and a cutaneous pigmentary lesion, without or with extracutaneous involvement. The case of an adolescent with epilepsy characterized by focal myoclonic seizures uncontrolled by an irregular pharmacological treatment, with skin lesions compatible with nevus flammeus and dermal, ocular and palatal melanosis since birth, is presented. This is the first report in the country of an infrequent neurocutaneous syndrome and its clinical association with epilepsy, highlighting besides the importance of a comprehensive evaluation of this entity.
ABSTRACT
INTRODUCCIÓN: El síndrome de Bourneville o esclerosis tuberosa es una alteración innata del desarrollo que se transmite de forma autosómica dominante, es causada por mutación en los genes TSC1 y TSC2. Se presenta en 1 de cada 6 000 habitantes; se considera una forma rara de facomatosis susceptible de originar tumores benignos en diversas zonas del cuerpo, entre los que se cita: angiomiolipomas renales, tumores del sistema nervioso, retina, corazón, piel y linfangioleiomiomatosis pulmonar; siendo la última una patología pulmonar quística, progresiva, que afecta a las mujeres en edad fértil y puede ser potencialmente mortal. CASO CLÍNICO: Se trata de una paciente de sexo femenino de 23 años de edad, mestiza, con antecedentes de esclerosis tuberosa, hipotiroidismo y nefrectomía izquierda por angiomiolipoma; que presentó un neumotórax espontáneo secundario a linfangioleiomiomatosis pulmonar. EVOLUCIÓN: En base a los antecedentes patológicos, cuadro clínico y estudios de imagen se diagnosticó de linfangioleiomiomatosis pulmonar. Se realizó una pleurodesis y se inició tratamiento con Sirolimus; la respuesta fue satisfactoria, se mantuvieron controles médicos periódicos evaluando la posibilidad de trasplante pulmonar a futuro. CONCLUSIÓN: El neumotórax espontáneo en una mujer joven con esclerosis tuberosa se asocia a linfangioleiomiomatosis pulmonar; en la actualidad esta patología es manejada con Sirolimus, los resultados han sido favorables en la función pulmonar y calidad de vida del paciente; el trasplante pulmonar sigue siendo el tratamiento de elección en la enfermedad avanzada.(au)
BACKGROUND: Bourneville syndrome or tuberous sclerosis is an innate development alteration transmitted by autosomal dominant inheritance. It is caused by TSC1 and TSC2 gene mutations and occurs in 1 of every 6 000 people. It is considered a rare form of phacomatosis that can cause multiple benign tumors including renal angiomyolipomas and tumors of the central nervous system, retina, heart and skin; pulmonary lymphangioleiomyomatosis can be part of the clinical presentation, affects women of childbearing age and can be life-threatening. CASE REPORT: 23 year-old female patient with history of tuberous sclerosis, hypothyroidism and left nephrectomy for angiomyolipoma, who presented a spontaneous pneumothorax secondary to pulmonary lymphangioleiomyomatosis. EVOLUTION: Based on the history, clinical picture and imaging studies; the diagnosis of pulmonary lymphangioleiomyomatosis was made. A pleurodesis was performed and a treatment with Sirolimus was started; the response was satisfactory, periodic controls were maintained evaluating the possibility of lung transplant in the future. CONCLUSION: Spontaneous pneumothorax in a young woman with tuberous sclerosis is associated with pulmonary lymphangioleiomyomatosis. Currently this pathology is managed with Sirolimus, the results have been favorable , improving pulmonary function and quality of life; lung transplantation remains the treatment of choice in advanced disease.(au)

RESUMEN El complejo esclerosis tuberosa (CET) es una enfermedad neurocutánea infrecuente y subdiagnosticada en zonas remotas donde usualmente no hay neurólogos disponibles. Una niña de 22 meses fue llevada a una clínica en una comunidad rural por un cuadro de epilepsia refractaria de causa no determinada, de inicio a los 18 meses de edad con episodios de oculogiros y espasmos epilépticos en extensión. Además presentaba angiofibromas perinasales y lesiones hipomelanóticas en tronco. El encefalograma interictal hecho en la comunidad mostraba actividad epiléptica multifocal y generalizada. La niña había sido llevada a la ciudad para una resonancia cerebral, la cual reveló hiperintensidades subcorticales multifocales y nódulos subependimarios. Por teleconsulta entre médicos de la comunidad y especialistas nacionales e internacionales se diagnosticó CET atípico con espasmos epilépticos de inicio tardío. Se sugirió tratamiento que logró control de las crisis y se estableció un plan de seguimiento. El caso muestra que las unidades de telemedicina en zonas rurales son una opción tecnológica para brindar acceso a atención especializada de las epilepsias.
ABSTRACT Tuberous sclerosis complex (TSC) is an uncommon neurocutaneous disease often underdiagnosed in remote areas where specialists in neurology are usually not available. A 22 month-old girl was taken to a clinic in a rural village presenting refractory epilepsy of undetermined cause that started at 18 months of age with upward eye deviation episodes and epileptic extensor spasms. She also presented perinasal angiofibromas and hypomelanotic skin lesions in trunk. The interictal encephalogram done in the community showed multifocal and generalized epileptic activity. The girl had been taken to the city for a brain magnetic resonance, which revealed multifocal subcortical hyperintensities and subependymal nodules. By teleconsult between community doctors and national and international specialists, atypical TSC with late onset epileptic spasms was diagnosed. The recommended treatment resulted in controlled seizures, and a follow-up plan was established. This case illustrates that telemedicine units in rural areas are a technological option to provide access to specialized epilepsy care.
ABSTRACT
Phacomatosis pigmentovascularis is a rare syndrome first described by Ota et al, in 1947. It ischaracterized by a combination of capillary malformation and other pigmented naevi. It had originallybeen classified into four major types. A fifth type, in which the vascular lesion is cutis marmoratatelangiectatica congenita (CMTC), was subsequently added. Each type was further categorizedaccording to the absence or presence of associated extra-cutaneous signs as types (a) and (b),respectively. We reported this case due to its rare clinical presentation, with probable overlap Klippel-Trenaunay syndrome.
ABSTRACT
Phacomatosis pigmentovascularis is a rare group of syndromes characterized by the co-existence of a vascular nevus and a pigmentary nevus with or without extracutaneous systemic involvement. The existing classifi cations of phacomatosis pigmentovascularis are based on phenotypic characteristics. We report four new cases of phacomatosis pigmentovascularis, three with phacomatosis cesiofl ammea demonstrating phenotypic variability, and one with phacomatosis cesiomarmorata. Extracutaneous manifestations were observed in three patients (75%) that included central nervous system involvement in three, bilateral congenital glaucoma in two, and cardiovascular system involvement in one. The molecular basis of phacomatosis pigmentovascularis is yet to be elucidated. Whether the various subtypes of phacomatosis pigmentovascularis are separate molecular entities or phenotypic variants of the same disease needs to be settled.
ABSTRACT
Phacomatosis pigmentovascularis (PPV) is a rare syndrome characterized by concurrent nevus flammeus (capillary malformation) and pigmentary nevus. According to current research, the major pathophysiologic mechanism in PPV is venous dysplasia with resultant compensatory collateral channels and venous hypertension. Arterial involvement is rare. We herein report our experience on renovascular hypertension, intermittent claudication, and severe rhabdomyolysis due to diffuse stenosis of multiple arteries in a patient with PPV type IIb associated with SWS.

La facomatosis pigmentovascularis se caracteriza por la coexistencia de malformaciones vasculares cutáneas con nevus melanocíticos y hasta en un 50 % de los casos puede tener compromiso sistémico. El sistema de clasificación tradicional identificaba cinco categorías, numeradas del I al V de acuerdo a la presencia de cierto tipo de nevus, subdivididos en tipo a y b dependiendo de si existe o no compromiso sistémico. Más recientemente, Happle propone una nueva categorización basada en los hallazgos clínicos así: cesioflammea (mancha mongólica y nevus flammeus), spilorosea (nevus de Spilus y nevus telangiectásico) y cesiomarmorata (mancha mongólica y cutis marmorata telangiectásico congénita), siendo la primera la más común. Se presenta el caso de un paciente masculino de tres años de edad, quien desde el nacimiento presentaba una malformación vascular capilar tipo nevus flammeus extenso, mancha mongólica, melanosis escleral e iris mamilado, una malformación venosa congénita localizada en la región suprapúbica, además de alopecia triangular, a quien se le hizo el diagnóstico inicial de facomatosis pigmentovascularis tipo cesioflammea y posteriormente se asoció a síndrome de Klippel Trenaunay.
Phacomatosis pigmentovascularis is a disorder characterized by cutaneous vascular malformations associated with melanocytic nevi: up to 50 % of patients have systemic involvement. The traditional classification system identifies 5 categories numbered from I to V according to the presence of certain types of nevi, and it subdivides the categories into type a and b, depending on whether or not systemic involvement is present. More recently, Happle proposed a new classification based on clinical findings as follows: cesioflammea (Mongolian spot and nevus flammeus), spilorosea (telangiectatic nevus and nevus Spilus) and cesiomarmorata (Mongolian spot and congenital telangiectatic cutis marmorata), the first one being the most common one. We present a case of a 3 year old male patient who presented at birth with a capillary vascular malformation, an extensive nevus flammeus, a Mongolian spot, scleral melanosis and mammilated iris, a suprapubic congenital venous malformation and triangular alopecia; he was diagnosed with cesioflammea phacomatosis pigmentovascularis that was later associated with Klippel Trenaunay Syndrome.

Phacomatosis pigmentokeratotica (PPK) is a rare syndrome defined by the association of an organoid nevus occasionally with sebaceous differentiation, a speckled lentiginous nevus, and other extracutaneous anomalies. A preterm male infant of only 830 g at 27 week gestational age had an organoid nevus showing sebaceous differentiation. Also, he had multiple speckled-lentiginous nevus. Correlating the observed clinical presentation with the histopathological findings, the diagnosis of PPK was established. There have been less than 10 cases of PPK without extracutaneous manifestation. We present an uncommon case of a preterm patient with PPK who had no extracutaneous abnormalities.

Introdución: El síndrome de Sturge-Weber (SSW) es una entidad neurocutánea congénita caracterizada por una malformación vascular facial (mancha en vino de Oporto) asociado a angiomatosis leptomeníngea. Su prevalencia es aproximadamente de uno por cada 50 000 nacidos vivos. Afecta por igual a ambos sexos. Las manifestaciones clínicas incluyen a las convulsiones, nevus vascular cutáneo unilateral en relación a la división oftálmica del nervio trigémino, glaucoma ipsilateral, hemiparesia contralateral, hemiatrofia, hemianopia y retraso psicomotor. La característica radiológica es la presencia de calcificaciones giriformes en los lóbulos occipital y parietal. Reporte de caso: Una paciente de 1 año 7 meses llegó a la emergencia presentando convulsiones generalizadas que cesaron con diazepan, y se inició tratamiento con ácido valproico. Mostraba una mancha congénita color vino de Oporto en la frente, además se evidenció un leve retraso psicomotor. La tomografia mostró una calcificación cortical en los lóbulos parietal y occipital izquierdos. En la resonancia magnética se evidenció un reforzamientoleptomeníngeo parietal izquierdo. Conclusiones: El SSW es una entidad rara y de curso progresivo, el diagnóstico no es difícil cuando las manifestaciones típicas están presentes. Una malformación cutánea facial y la presencia de retardo mental debería alertar a los médicos cuando se encuentran frente a niños con convulsiones focales o parciales complejas secundariamente generalizadas en el primer o segundo año de vida.
Introduction: Sturge- Weber syndrome (SWS) is a congenital neurocutaneous syndrome characterized by unilateral facial cutaneous vascular malformation (Port-wine stain) in association with ipsilateral leptomeningeal angiomatosis. Prevalence is approximately one per 50 000 live births. Males and females are equally affected. Clinical manifestations include seizures, unilateral cutaneous vascular nevus following the ophthalmic divisions of the trigeminal nerve, ipsilateral glaucoma, contralateral hemiparesis, hemiatrophy, hemianopia and psychomotor retardation. The radiographic hallmarks of SWS are gyriform calcifications usually involving the occipital and parietal lobes. Case report: A 1 year and 7 month-old girl carne to emergence department showing generalized seizures that resolved with diazepam and valproic acid was started. She had a facial Port-wine birthmark located on the forehead; a mild psychomotor retardation was evidenced. Head CT demonstrated a cortical calcification of the left parietal and occipital lobe. MRI showed a left parietal leptomeningeal enhancement. Conclusions: SWS is a rare and progressive entity, the diagnosis is not hard when typical manifestations are present. Mental retardation and facial cutaneous malfonnations should alert physician when they are in front of infants with focal or complex partial/secondarily generalized seizures in the first or second year of life.

Phacomatosis cesioflammea is a rare condition defined by the simultaneous presence of both vascular and pigmentary nevus in the same patient. We report a case of a 4-year-old Indian female child who presented with diffuse dermal melanosis on the upper shoulders, upper anterior chest and lower back and extending to involve both sides of the arms and forearms, generalized port-wine stain on the back, shoulders and both upper limbs with sparing of the right palm. At places, the two types of lesions were superimposed on each other and were also present discretely on the back, but in close proximity to each other. There was the presence of melanosis bulbi on the right side of the eye. She was otherwise normal. She was clinically diagnosed as a case of phacomatosis pigmentovascularis cesioflammea. The nonallelic twin spotting phenomenon has been proposed in the pathogenesis of this disorder.
ABSTRACT
La facomatosis pigmentovascularis es un síndrome infrecuente caracterizado por la asociación de un nevus vascular con un nevus pigmentario. Su etiología es desconocida. Se ha propuesto un modelo genético de didimosis o manchas gemelas. La clasificación previa establece cinco categorías, que a su vez se subdividen en a) cuando existe compromiso cutáneo y b) cuando existe compromiso cutáneo y sistémico. Se ha propuesto una nueva clasificación, más simple, que resume las 10 categorías previas en tres tipos definidos: facomatosis cesioflammea, facomatosis spilorosea y facomatosis cesiomarmorata. Además, agrega un cuarto tipo de FPV no clasificables. Se han descrito asociaciones con otras alteraciones de la piel, oculares, vasculares, neurológicas, inmunológicas y malformaciones, por lo cual es recomendable realizar un examen físico extenso y derivación a especialidades para descartar patologías asociadas. Presentamos el caso de una mujer de 27 años que presenta lesiones correspondientes a una facomatosis cesioflammea en la nueva clasificación.
Phacomatosis pigmentovascularis is an uncommon syndrome characterized by the association of a widespread vascular nevus with a pigmentary nevus. Its etiology is unknown. A twin spotting or didymosis genetic model has been proposed. The previous classification established five categories, further subdivided into a) when cutaneous involvement was present or b) when cutaneous and systemic involvement was present. A new, more straightforward classification has been proposed, which summarizes the ten previous categories into three distinct types: phacomatosis cesioflammea, phacomatosis spilorosea and phacomatosis cesiomarmorata. Furthermore, a fourth category of unclassifiable phacomatosis pigmentovascularis was added. Diverse associations of phacomatosis pigmentovascularis with other skin lesions, malformations, and ocular, vascular, neurological and immunological abnormalities have been described, hence the importance of an extensive physical examination and consultations to discard associated pathologies. We present the case of a 27 year old woman, diagnosed with phacomatosis cesioflammea, based on the new classification.
