CONGENITAL SIMPLE HAMARTOMA OF THE RETINAL PIGMENT EPITHELIUM: OPTICAL COHERENCE TOMOGRAPHY AND ANGIOGRAPHY FEATURES:

Congenital simple hamartoma of the retinal pigment epithelium

Congenital simple hamartoma of the retinal pigment epithelium (CSHRPE) is a rare tumor speculated to arise from the retinal pigment epithelium (RPE). A case of CSHRPE is presented herein along with the related literature. A healthy 20-year-old Middle-Eastern man was evaluated for an asymptomatic retinal lesion found on routine examination of his left eye. Fluorescein angiogram, spectral domain optical coherence tomography, and A and B scan ultrasonography confirmed the suspected clinical diagnosis. For the first time high-definition OCT images are shown, which have an RPE origin for this tumor.

Congenital simple hamartoma of retinal pigment epithelium: clinical and imaging findings

Congenital simple hamartoma of retinal pigment epithelium (CSHRPE) is a rare, asymptomatic, and incidentally detected benign lesion. However, it is very important to do the differential diagnosis from other pigmented retinal lesions. Its clinical presentation and imaging findings are very helpful in doing this differentiation. This paper presents clinical and imaging findings of a 56-year-old woman with incidentally detected CSHRPE. The lesion was small, heavily pigmented, well circumscribed, and slightly elevated. Optical coherence tomography (OCT) scanning was diagnostic and showed an elevated retina at the site of the lesion, increased optical reflectivity on its inner surface, optical shadowing of deeper structures, and clearly cut tumor margins. Ocular ultrasonography, fluorescein angiography, and fundus autofluorescence imaging which is firstly described in this report did not show any characteristic finding.
