The natural history of congenital inclusion dermoid cysts of the scalp is unknown. We report three cases of this condition, which has been followed from birth for up to ten years. Dermoids are congenital subcutaneous cysts, which gradually flatten and scar over a number of years. The lesions are covered with skin showing focal alopecia but they may be surrounded by a collar of hypertropic hair. Later in life flattened cysts may be mistaken for aplasia cutis, but the history of a cyst at birth allows the clinician to distinguish these two conditions. As these cysts have a potential for intracranial extension, this is an important clinical entity.
头皮先天性包涵性皮样囊肿的自然病史尚不清楚。我们报告了三例这种疾病，自出生起对其进行了长达十年的随访。皮样囊肿是先天性皮下囊肿，多年来会逐渐变平并形成瘢痕。病变部位覆盖着有局部脱发的皮肤，但可能被一圈增生的毛发所包围。在生命后期，扁平的囊肿可能会被误诊为皮肤发育不全，但出生时囊肿的病史可让临床医生区分这两种情况。由于这些囊肿有可能向颅内扩展，这是一个重要的临床实体。
