[Isolated congenital hamartoma of retinal pigment epithelium in a long term follow-up--case report].

Retinal pigment epithelium hamartomas are rare, benign tumors, usually with no growth potential. The case of hamartoma observed at the Ocular Oncology Service, Department of Ophthalmology, University of Medical Sciences in Poznań is presented. In 2008 a 30-year-old woman presented with an asymptomatic choroidal pigmented lesion. Fundus evaluation revealed a lesion typical of retinal pigment epithelium hamartoma. The optical coherence tomography, fluorescein angiography and indocyanine green angiography results confirmed the diagnosis of retinal pigment epithelium hamartoma. No lesion growth was documented throughout the follow-up period of 4 years. Differential diagnosis between congenital retinal pigment epithelium hypertrophy (congenital hypertrophy of the retinal pigment epithelium) or uveal melanoma was included in the report. retinal pigment epithelium hamartoma, fluorescein angiography, optical coherence tomography.
