The sacrococcygeal region is the frequent site for meningocele, congenital dermal sinus and pilonidal cyst. From May 1995 to July 1998, we have treated 8 neonatal patients with an abscess in the sacrococcygeal area. The mean age at onset was 8.3 days with a range from 6 to 11 days. The sex ratio was 5:3 with male preponderance. Mild fever was the only systemic symptom. Ultrasonogram revealed a slightly hypo echoic lesion in the subcutaneous tissue which became more hypoechoic with time. Pus cultures showed Staph. aureus in 7 patients, two of them had mixed infection with E. coli and other 2 had methicillin-resistant Staph. aureus. The remaining one patient had a mixed infection with Klebsiella and Proteus. Histopathological examination revealed non-specific granuloma and fibrinoid necrotic debris. All patients were easily treated by incision, drainage and proper antibiotics.
