Anomalía de Poland, a propósito de dos casos / Poland anomaly, about two cases

Introducción: el síndrome de Poland, conocido también como secuencia de Poland o anomalía de Poland, fue descrito por primera vez por Alfred Poland en 1841. Corresponde a una alteración musculoesquelética congénita, caracterizada por la ausencia total o parcial del músculo pectoral mayor, asociada a anormalidades de la extremidad superior ipsilateral. Objetivo: se presentan 2 casos de niñas que consultaron por asimetría mamaria, en el primer caso una niña de 12 años con ausencia del pectoral mayor y antecedente de postquirúrgicos sindactilia de mano derecha ipsilateral. El segundo caso, una niña de 9 años con asimetría mamaria sin alteración en la extremidad. Conclusión: la anomalía de Poland o secuencia de Poland es una alteración musculoesquelética de presentación infrecuente, de aparición esporádica, de mayor prevalencia en masculinos, afecta generalmente el lado derecho del cuerpo, muy pocas veces amerita tratamiento quirúrgico

Introduction: Poland syndrome, also known as Poland sequence or Poland anomaly, was first described by Alfred Poland in 1841. It corresponds to a congenital musculoskeletal disorder, characterized by the total or partial absence of the major pectoral muscle associated with limb abnormalities ipsilateral superior. Objective: There are 2 cases of girls who consulted for breast asymmetry, in the first case a 12-year-old girl with absence of the pectoralis major and a history of post-surgical syndactyly of the right ipsilateral hand, the second case a 9-year-old girl with breast asymmetry without limb alteration Conclusion: The anomaly of Poland or sequence of Poland is a musculoskeletal alteration with an infrequent presentation, of sporadic appearance, more frequent in males, 10 frequently affecting the right side of the body, very rarely merits surgical treatment.

Síndrome de nevo de Becker con características ictiosiformes / Becker's nevus syndrome with ichthyosiformes features

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.

A Case of Becker's Nevus Associated with Ipsilateral Hypoplasia / 대한피부과학회지

Becker's nevus is a cutaneous hamartoma characterized by unilateral hairy hyperpigmentation and can be associated with subjacent and distant soft tissue and bony abnormalities. Ipsilateral breast hypoplasia is a rare abnormality in Becker's nevus, suggesting that increased androgenic receptors or early postzygotic mutation may play a role in the pathogenesis of Becker's nevus. We report a case of Becker's nevus associated with ipsilateral breast hypoplasia in a 24-year-old female.

A Case of Becker's Nevus Associated with Ipsilateral Breast Hypoplasia / 대한피부과학회지

We report a case of Becker's nevus associated with ipsilateral breast hypoplasia in a 13-year-old female. Three years esrlier, she noticed a palrn-size hyperpigmented area on her left chest. The lesion showed a well defined geographic border. No hypertrichosis was seen. Hypoplasia was apparent on the left breast. A histopathologic finding showed a slightly hyperpigmented epidermis and some rectangular rete ridges with flat bases.
