SMIT, Rosina et al. Retrorectal cyst hamartoma: Report of a pediatric case. Arch. argent. pediatr. [online]. 2010, vol.108, n.3, pp.e82-e85. ISSN 0325-0075.

The retrorectal hamartoma cyst or retrorectal cyst is an uncommon congenital lesion. We present the case of a 7 days-old girl with a retrorectal tumor diagnosed by ultrasound during pregnancy. The histological examination was a cyst lined by squamous and urotelial typical epithelium and a double layer of smooth muscle. The treatment of choice is the complete excision of the lesion, as local recurrences or a malignant transformation have been observed.

Palabras clave : Retrorectal hamartoma cystic; Retrorectal cyst.
