Case records of 32 patients (22 female and 10 male) with sacrococygeal teratoma who were treated in our department between 1984 and 1994 were reviewed. 27 patients had benign sacrococcygeal teratoma and the majority of the benign sacrococygeal teratomas were newborns. Total excision with coccygectomy was performed in this group. In cont¬rast, only one of the patients with malignant tumor was a newborn. In malignant group excision and multiagent chemotherapy were used for the treatment and two recurrences were noted. The average survival was increased and early mortality was decreased for all patients in comparison with past decades. 1984 ile 1994 yıllan arasında servisimizde takip edilen 32 Sakrokoksigeal teratomlu hasta (22 kız ve 10 erkek) yeniden gözden geçirildi. Hastaların 27 tanesi benign teratomdu ve bunlann çoğu yenidoğan döneminde başvurmuştu. Bu gruptaki hastalara total ekslzyonla beraber koksigektomi uygulandı. Tersine, malign tümör grubunda yalnız bir hasta yeni¬doğan döneminde başvurmuştu. Bu grupta ise tedavi amacıyla ekzisyon ve multiajan kemoterapi uygulandı ve iki rekürens gözlendi. Geçen dekadlarla karşılaştınldığında, son dekadda hastaların yaşam sürelerinin uzadığı ve erken mortalitenin düştüğü saptandı.
