ABSTRACT
OBJECTIVE: To develop consensus on diagnostic criteria for LUMBAR syndrome, the association of segmental infantile hemangiomas that affect the Lower body with Urogenital anomalies, Ulceration, spinal cord Malformations, Bony defects, Anorectal malformations, Arterial anomalies and/or Renal anomalies. STUDY DESIGN: These diagnostic criteria were developed by an expert multidisciplinary and multi-institutional team based on analysis of peer-reviewed data, followed by electronic-Delphi consensus of a panel of 61 international pediatric specialists. RESULTS: After 2 Delphi rounds, a 92% or higher level of agreement was reached for each Delphi statement. 98% of panelists agreed with the diagnostic criteria, and 100% agreed the criteria would be useful in clinical practice. The diagnosis of LUMBAR requires the presence of a segmental, or patterned, infantile hemangioma of the lumbosacral, sacrococcygeal, or pelvic cutaneous regions plus one additional criterion of the urogenital, spinal, bony, anorectal, arterial, or renal organ systems. CONCLUSIONS: These diagnostic criteria will enhance clinical care by improving screening, detection, and overall awareness of this poorly understood neurocutaneous disorder. The criteria can be utilized by a wide variety of pediatric subspecialists. In addition, formal criteria will improve phenotypic uniformity among LUMBAR syndrome cohorts and a patient registry, allowing investigators to assess clinical features, long-term outcomes, and results of genetic sequencing in a standardized manner. Finally, these criteria will serve as a starting point for prospective studies to establish formal screening and management guidelines.

La asociación MURCS (Mullerian aplasia, Renal aplasia, Cervicothoracic Somite dysplasia) (OMIM%601076) hace referencia a un conjunto de anomalías congénitas, que sin ser debidas al azar, aparecen de forma concomitante en una persona. Se caracteriza por una aplasia Mülleriana, aplasia renal y displasia cérvico-torácica provocadas por alteraciones en los somitas correspondientes, es de etiología heterogénea. Se presenta el caso de una paciente de 9 años de edad, que es diagnosticada con la asociación MURCS, por presentar agenesia uterina, hipoplasia y ectopia renal unilateral y malformación de la 5ta vértebra cervical. Se enfatiza en la importancia de la búsqueda activa de las otras anomalías diferentes a las Müllerianas para lograr el diagnóstico y realizar un manejo integral e interdisciplinario.
The MURCS association (Mullerian aplasia, renal aplasia, Cervicothoracic Somite dysplasia) (OMIM%601076) refers to a set of congenital abnormalities, without being due to chance, they appear concomitantly in a person. It is characterized by Müllerian aplasia, renal aplasia and cervicothoracic dysplasia caused by alterations in the corresponding somites. We describe a case report of a 9-year-old female, who is diagnosed with MURCS association, to present uterine agenesis, hypoplasia and unilateral renal ectopia and deformity of the 5th cervical vertebra. We emphasize the importance of interdisciplinary care, including a clinical geneticist in the care of patients with these characteristics.
