We report the cases of two children who were each noted at birth to have a single bald compressible nodule on the scalp that was surrounded by a collar of hypertrophic hair. One of the mothers had taken doxylamine succinate during pregnancy. Extensive investigations and, finally, surgery revealed that the lesions were heterotropic brain tissue without connection to the brain. Encephaloceles may also have a "hair collar." The presence of a hair collar around any cutaneous lesion should alert the clinician to the possibility of a neuroectodermal defect. All procedures on these lesions should be delayed until appropriate investigations have excluded any connection with the underlying nervous system.
我们报告了两名儿童的病例，他们在出生时均被发现头皮上有一个单一的可压缩性秃发结节，周围有一圈肥厚的毛发。其中一位母亲在怀孕期间服用了琥珀酸多西拉敏。广泛的检查以及最终的手术表明，这些病变是异位脑组织，与大脑无连接。脑膨出也可能有“毛发圈”。任何皮肤病变周围出现毛发圈都应提醒临床医生注意神经外胚层缺陷的可能性。在对这些病变进行任何操作之前，都应推迟，直到适当的检查排除了与潜在神经系统的任何连接。
