To describe a unique unilateral association between an iris stromal tumor and a macular focal choroidal excavation.
A 40-year old patient presented with a small iris tumor associated with a unilateral macular lesion disclosed during a routine ophthalmologic examination. The patient was asymptomatic and visual function was not affected. After clinical and instrumental evaluation, a diagnosis of nonmelanocytic undefined stromal tumor of the iris associated with macular focal choroidal excavation was made. The size and shape of the two lesions remained stable during a 7-year follow-up and the patient did not develop other signs.
The concurrent presence of a stromal iris tumor associated with focal choroidal excavation has never been reported. Further reports of this association are required in order to understand its exact pathogenesis.
