ABSTRACT
El nevo de Becker, es un hamartoma cutáneo benigno de etiología desconocida, que se presenta como una mácula hiperpigmentada de bordes geográficos. Por lo general, se ubica en la región torácica superior y su compromiso tiende a ser unilateral. Ocasionalmente el nevo de Becker se asocia a anomalías en el tejido óseo, muscular o cutáneo, siendo la ictiosis una característica muy infrecuente. La presencia de alguna de estas anomalías asociadas a un Nevo de Becker determina el síndrome del Nevo de Becker. Paciente de sexo masculino de 18 años, que consultó por un cuadro iniciado en la infancia, caracterizado por la aparición de manchas cafés, escamosas, pruriginosas que inicialmente se ubicaron en las extremidades inferiores y con el tiempo fueron apareciendo en tronco, región lumbar y glútea. Mediante la correlación clínico-patológica se llegó al diagnóstico de Nevo de Becker, con características ictiosiformes. Se realizaron estudios complementarios con ecocardiograma Doppler y radiografía de tórax, que resultaron normales y una ecotomografía Doppler color de tórax anterior que mostró una leve ginecomastia bilateral con discreto aumento del botón mamario derecho y una leve hipoplasia del pectoral mayor derecho diagnosticándose Síndrome de Nevo de Becker. La mayoría de los reportes de Síndrome de nevo de Becker describen anomalías como escoliosis o hipoplasia unilateral de la mama, con escasos reportes sobre ictiosis. Se reporta este caso por su presentación atípica con múltiples nevos de Becker, compromiso de hemicuerpo inferior y su asociación ictiosiforme poco descrita en la literatura.
Becker's nevus is a benign cutaneous hamartoma of unknown etiology; it appears as a hyperpigmented macula with geographical borders. Usually it is located in the upper thoracic region, unilaterally. Occasionally Becker nevus is associated with abnormalities in the bony, muscle or skin tissue, being ichthyosis an unusual feature. The presence of some of these anomalies associated with Becker´s nevus determine the Becker´s nevus syndrome. Male patient of 18 years old who had a clinical history that begun in childhood, characterized by the appearance of brown, scaly, itchy patch that initially were located in the lower extremities and eventually were appearing in the trunk, lumbar and gluteal area. The clinical-pathological correlation led us to the diagnosis of Becker´s nevus with ichthyosiform features. Additional studies were performed such as Doppler echocardiography and chest radiograph, both normal. Color Doppler ultrasonography of anterior chest showed a slight bilateral gynecomastia with discrete increase of the right breast and a slight hypoplasia of the right major pectoral, determining a Becker´s nevus syndrome. Most reports of Becker´s nevus syndrome described abnormalities such as scoliosis or unilateral breast hypoplasia, few cases have been reported with ichthyosis. This case is reported for its atypical presentation with multiple Becker´s nevus, compromise of the lower body and its ichthyosiform association, rarely described in the literature.

Becker nevus syndrome is a phenotype characterized by the presence of a Becker nevus in association with unilateral hypoplasia of the breast or other cutaneous, muscular or skeletal defects. We report an interesting case of Becker's nevus syndrome associated with fibrous dysplasia of the sphenoid bone, tooth abnormalities and facial asymmetry.
