Combined Hamartoma of Retina and Retinal Pigment Epithelium Masquerade as Choroidal Melanoma in Young Patient

Abstract

Introduction: Combined hamartoma of retina and retinal pigment epithelium is a rare benign ocular tumour resulting
from abnormal proliferation of glial cells, vascular tissue and pigment epithelial cells

Case: A 29-year-old male presented with complaint of diminution of vision in his right eye, noticed incidentally
during screening.

Observation: On examination, a flat, unilateral, solitary, greyish brown peri-papillary lesion with irregularly
pigmented border with an epiretinal membrane in right eye. The Optical Coherence Tomography showed a thickened
retina with disorganisation of retinal layers, a hyper-reflective inner retinal layer with fine retinal traction peaks, and
presence of an epiretinal membrane. Histopathological examination was not done.

Conclusion: Combined hamartoma of retina and retinal pigment epithelium is a rare benign tumour. Proper diagnosis
is important as it can be confused with more severe pathologies like choroidal melanoma, Retinal pigment epithelium
adenocarcinoma.
