Neonates presenting with perineal masses are uncommon. When encountered, most perineal masses are anorectal malformations, sacrococcygeal teratomas, rectal prolapse, or duplication cysts.
Neonates presenting with perineal masses should undergo further imaging and evaluation to rule out additional congenital deformities. Aggressive treatment of mass lesions, in the form of wide local excision, is often the treatment of choice and is associated with fewer local recurrences in adults. The aim of surgery is to obtain negative resection margins without causing disturbances to urinary or anorectal function [1].
A newborn presenting with a pediculated mass arising from the anal margin. Antenatal sonogram and magnetic resonance imaging were unable to diagnose the precise nature of the lesion.so we put the differential diagnosis of Sacrococcygeal teratoma, an enterogenous cyst, a polyp, a prolapse or other perineal tumors were all proposed as possible entities. At birth, no other anatomic anomaly than this homogenous 2 cm –anal mass protruding from anus. Excision of the mass was performed under general anesthesia. The postoperative histological exam showed mature fat cells most probably its being lipoma).
