BACKGROUND: Retinal tumors are occasionally seen in patients with neurofibromatosis type-1 (NF-1). These are usually astrocytic hamartomas or angiomas. Combined hamartoma of the retina and retinal pigment epithelium are tumors also described in NF-1, but this association has not been definitively established yet. METHOD: We report on a child with NF-1, who presented a combined hamartoma of the retina and retinal pigment epithelium in both eyes. RESULTS: The diagnosis of bilateral combined hamartoma of the retina and retinal pigment epithelium in our patient was performed on the basis of the ophthalmoscopic appearance of the lesions. NF-1 was diagnosed following the current international clinical criterion, supplemented by neuroimaging findings. CONCLUSION: Despite the extreme rarity of this association, we believe that it is not coincidental, as the presence of a hamartomatous retinal lesion in a patient with a systemic hamartomatous neuroectodermic disease would be, at least, rational. Thus, NF-1 must be excluded in patients with combined hamartoma of the retina and retinal pigment epithelium.
