RESUMO
Brachmann-De Lange Syndrome (BDLS, MIM 122470) is a rare multiple congenital anomaly/mental retardation syndrome characterized by a variable phenotype including intrauterine fetal growth retardation, limb reduction and distinctive facial and skull features (low frontal hairline, synophrys, anteverted nostrils, long philtrum, downturned corners of the mouth, micro- and retrognathia, low-set ears and micro-/brachycephaly), as well as a significant psychological developmental delay. A proposed classification system for BDLS include a classic type with characteristic facial and skull changes, a mild type where similar changes may develop with time or may be partially expressed, and a third type including phenocopies, where phenotypic changes are casually related to chromosomal aneuploidies or teratogenic exposures. We report on a 22-week gestation fetus with BDLS, showing intrauterine fetal growth retardation, brachycephaly, micro-/retrognathia and monolateral single bone of the forearm, in a woman harboring diffuse large B-cell lymphoma. Meticulous family history was negative for malformations, syndromes, congenital anomalies or psychiatric disorders. There are very few reports of BDLS at early gestation, but to the best of our knowledge, this is the first case occurring simultaneously with a hematological neoplastic disease of the mother.
