RESUMEN
Scrotal angiokeratoma(Fordyce angiokeratoma)is often seen in elderly men presenting nodular hemorrhage. In this study, 8 cases of scrotal angiokeratoma were treated with 980nm diode laser. All the operations were successfully completed under local anesthesia without obvious complications and local symptoms improved. The results showed that 980nm diode laser is an alternative operation for the treatment of scrotal angiokeratoma.
RESUMEN
Abstract Isolated angiokeratomas (AKs) are common cutaneous lesions, generally deemed unworthy of further investigation. In contrast, diffuse AKs should alert the physician to a possible diagnosis of Fabry disease (FD). Angiokeratomas often do not appear until adolescence or young adulthood. The number of lesions and the extension over the body increase progressively with time, so that generalization and mucosal involvement are frequent. Although rare, FD remains an important diagnosis to consider in patients with AKs, with or without familial history. Dermatologists must have a high index of suspicion, especially when skin features are associated with other earlier symptoms such as acroparesthesia, hypohidrosis, or heat intolerance. Once the diagnosis is established, prompt screening of family members should be performed. In all cases, a multidisciplinary team is necessary for the long-term follow-up and treatment.
RESUMEN
La Enfermedad de Fabry (EF) constituye una alteración hereditaria del metabolismo de los glicoesfingolípidos, debida a la deficiencia parcial o completa de la enzima alfa-galactosidasa A. Es una enfermedad de transmisión genética ligada a X, que afecta universalmente a todas las etnias humanas con una incidencia comunicada de 1 cada 100.000 nacimientos, aunque es probable que esta cifra subestime la real prevalencia de la enfermedad, especialmente por el gran número de casos no diagnosticados. La EF se manifiesta en su forma más florida, en varones homocigotas que carecen completamente de actividad alfa-galactosidasa A, provocando una miríada de alteraciones, incluyendo anomalías renales (proteinuria progresiva e insuficiencia renal), cardiovasculares (cardiopatías, arritmias, accidentes cerebrovasculares), neurológicas (dolor acral y abdominal), y cocleo-vestibulares, entre las más importantes. Sin embargo, la afectación cutánea constituye la alteración más específica de la enfermedad y es en general, la que conduce a la sospecha diagnóstica. La EF no tratada reduce francamente la expectativa de vida de acuerdo a la severidad de la afectación renal y cardiovascular, si bien la terapia con reemplazo enzimático puede modificar e incluso detener el curso de la enfermedad. En 2010, una paciente de 28 años oriunda de la Provincia de Santa Fe, consultó porangioqueratomas, que condujeron al diagnóstico de enfermedad de Fabry. Desde entonces hemos estudiado y tratado a toda la familia, con ocho casos confirmados a la fecha y otros tantos en evaluación.
Fabry disease (Online Mendelian Inheritance in Man No. 301500) is an X-linked inherited condition due to absence or reduction of ɑ galactosidase activity in lysosomes that results in accumulation of globotriaosylceramide and related neutral glycosphingolipids (storage disorder). It is estimated to occur in 1 in 40.000 to 117.000 live male births, although a more recent screening study in newborns suggests a much higher incidence. The main clinical traits include cutaneous lesions (angiokeratomas), progressive renal damage with proteinuria, painful neuropathy predominantly affecting the hands and feet (acroparesthesias), myocardial hypertrophy, gastrointestinal manifestations, corneal dystrophy and hypohidrosis. This entails severe progressive multi-system involvement leading to premature death. More than 600 mutations have been described worldwide most of which are private or particular mutations of a single family. We report a 28 years-old woman who consulted to one of us and since 2010 eight cases of the same family were studied and treated with support and enzyme replacement therapy in order to delay the damage to the end organ.
RESUMEN
We report a 13-year-old girl with multiple angiokeratomas on lower extremity. Her skin lesions were asymptomatic but became larger and darker and bled intermittently with subtle trauma. Skin biopsy confirmed the diagnosis of angiokeratoma. We emphasize the importance of this lesion in the differential diagnosis of pigmented nevus or malignant melanoma.
