Mullerian anomalies are one of the interesting but uncommon entities that gynecologists confront. The incidence is 1-6%, It is difficult to" anticipate the real incidence, because most of information is obtained from infertile or complicated patients with inadequate work-up. Recently endoscopic pocedures reveal more details about these anomalies. Today, classification of Buttram & Gibbons (modified by AFS [American Fertility Society]) is accepted. In this paper one patient with septate uterus, duplication of cervix and vaginal septum is introduced. According to information obtained, only one similar case is reported (by McBean et al). This entity is not conformed with AFS classification. Only in Toaff et al classification, there is a class similar to these patients. This entity is not explained by classic embryological theory of mullerian development
