Abstract

Purpose To evaluate our experience with 45 patients with sacrococcygeal teratoma (SCT) in our community (upper Egypt) over a period of 10 years between 2001 and 2011 and determine the outcome of the management and recommendations for treatment strategies.
Patients and methods A retrospective study was conducted at our Pediatric Surgical Unit, Assiut University Hospital. The medical records were reviewed for age at presentation, clinical manifestations and investigations, time of surgical approach, histopathology, recurrences, bladder and anorectal function, and cosmetic outcome.
Results Forty-five patients with SCT were referred to the Pediatric Surgical Unit. The time of referral was as follows: immediately after birth in the case of five patients; during the first week for 17 patients (four of them died before surgery because of hemodynamic instability and other associated congenital anomalies and were excluded from the study); later in infancy for 22 patients; and at one and half years of age for one child. The lesion was excised in the case of 41 patients. Teratomas were of type I (n =9), type II (n = 20), type III (n= 11), and type IV (n =1) (Altman’s classification). The age of patients at surgery ranged from 2 days to 1.5 years. Histological analysis of results revealed mature teratoma (n =27), immature teratoma (n =9), and malignant teratoma (n= 5). The coccyx was not removed in two cases during the early period of the study. The follow-up period ranged from 3 months to 10 years. Recurrence occurred in five (12%) cases, wound infection in four (9.7%), and diarrhea in two (4.8%) cases. The a-fetoprotein level was high in 35 cases and was normal in two patients; it decreased after excision. Fetal diagnosis was made in five cases by means of a prenatal sonographic scan.
Conclusion Prenatal diagnosis of SCT is very important and it is recommended to save the baby from obstructed labor. Early diagnosis allows early surgical intervention and avoids malignant transformation. The coccyx should be excised to decrease the risk of recurrence. Skin flap modification is feasible for large teratomas with healthy skin.
