title: Infantile neuroblastoma presenting with cutaneous blanching nodules.
abstract: An 8-week-old girl was seen because of firm, blue cutaneous nodules. A biopsy showed neuroblastoma. When rubbed, the nodules blanched and were surrounded with a halo of erythema. She had Horner's syndrome, hepatomegaly, bone marrow and shaft invasion, and a high thoracic mass with signs of spinal cord compression. Blanching cutaneous nodules are a unique finding in neuroblastoma and may be the first sign of this disease.
