The Authors report an unusual case of median cleft of the upper lip with pedunculated skin and muscle contracting mass. About one hundred cases of true median cleft lip have been reported, only six showing a median pedunculated mass. As the embryogenesis of this malformation is still not completely clear, we think that any case with this characteristic has to be described. Besides the usual characteristic of the median "hare lip" this case shows a big egg-like pedunculated mass in which muscular tissue has been found well represented, and a wide incomplete maxillary cleft.
作者报告了一例罕见的上唇正中裂合并带蒂皮肤及肌肉收缩性肿块的病例。据报道，真性正中唇裂约有100例，仅有6例伴有正中带蒂肿块。由于这种畸形的胚胎发生仍不完全清楚，我们认为任何具有这种特征的病例都应予以描述。除了正中“兔唇”的常见特征外，该病例还显示出一个大的卵状带蒂肿块，其中发现有大量肌肉组织，以及一个广泛的不完全性上颌裂。
