Raised limb bands developing in infancy

Abstract

Congenital cutaneous constriction bands are rare and often occur with other abnormalities, including the presence of rudimentary digits. This diverse syndrome lacks a precise definition and a satisfactory explanation. We describe two unusual cases with features previously undescribed, in which predominantly raised, annular limb bands became apparent postnatally. One infant was also born with foreshortened digits and a constricting limb band, suggesting a shared aetiology with other congenital cases. The development of raised bands during infancy would be difficult to reconcile with the widely held 'amniotic band hypothesis', and would be more in keeping with a multifocal developmental abnormality in limb growth.

Sock-Line Hyperpigmentation: Case Series and Literature Review

“…[2][3][4][5] This entity is characterized by acquired, asymptomatic, skin-colored, linear, raised plaques. Additionally, several articles have described an entity termed acquired raised bands of infancy.…”

Bilateral linear red lines on the calves in an infant

“…Cases similar to sock‐line bands were first reported in 2002 with subsequent similar case reports ; however, on retrospective review, these cases likely represented acquired raised bands of infancy (ARBI). In this condition, patients present with skin‐colored asymmetric linear diagonal plaques.…”

Hiperpigmentación de la línea del calcetín

“…Con esta última entidad hay bastante confusión en la bibliografía, ya que por su similitud parece que lesiones compatibles con hiperpigmentación de la línea del calcetín han sido inicialmente clasificadas de forma errónea como bandas adquiridas de la infancia. Las bandas adquiridas de la infancia se caracterizan por ser palpables, asimé-tricas, orientadas en cualquier ángulo y no hiperpigmentadas, y por localizarse preferentemente de forma proximal en la extremidad [3][4][5][6] . La peculiaridad de este caso es la aparición de varias lesiones en relación a las zonas de presión por diferentes modelos de calcetines, lo que apoya la estrecha relación postraumática de esta entidad 7 .…”
