Ciliary Body Melanoma – A Particularly Rare Type of Ocular Tumor. Case Report and General Considerations
Uveal melanoma is the most common primary malignancy of the eye in white adults. Frequently, uveal melanoma arises from choroid or iris. Ciliary body melanoma is a rare if not exceptional subtype of uveal melanoma. Furthermore, ciliary melanoma is often seen in association with the other two subtypes of uveal melanoma. This paper presents a case of primary ciliary melanoma with invasion of the iris. The patient presented with blurred vision, but this symptom could not doubtless be related with the existence of the tumor, because of the small dimension of the malignancy and the lack of medical history of the patient. This tumor was included in the category of “very small ciliary melanoma”, a rare diagnosis considering the fast local invasion and the lack of symptoms in such a small tumor. Histopathological and imunohistochemical examinations confirmed the diagnosis of ciliary melanoma, This type of ocular melanoma has a low prognosis due to early metastases.
