Persistent intraschisis hemorrhage simulating choroidal melanoma.

Immunoimaging of choroidal melanoma: assessment of its diagnostic accuracy and limitations in 101 cases.

Immunoscintigraphy (IS) was performed on 101 patients with space occupying intraocular lesions including choroidal melanomas (85), choroidal naevi (11), non-melanoma metastases (three), and other melanoma simulating lesions (two). Scintigraphic images with conventional and emission computer tomography techniques were obtained after the intravenous injection of 99mTc-labelled F(ab')2 fragments o...

Hemorrhagic retinal macrocysts, simulating choroidal melanoma: a case report

INTRODUCTION Hemorrhagic retinal macrocysts are extremely rare retinal lesions that can be mistaken for malignancy with subsequent enucleation. Such a case was diagnosed, by a retina specialist based on ultrasonography, as a choroidal melanoma with exudative retinal detachment and the patient was advised to have brachytherapy. CASE PRESENTATION A 15-year-old Caucasian boy suffered sudden visu...

Hemorrhagic choroidal melanoma

Purpose To demonstrate the clinical pathologic correlation in a hemorrhagic choroidal melanoma. Observations A 52 year old patient presented with a large choroidal mass associated with vitreous and retinal hemorrhage. The eye was enucleated and histopathology demonstrated epithelioid-type MART1 positive tumor cells consistent with choroidal melanoma. The tumor had broken through Bruch's membr...

Fulminant hepatic failure due to metastatic choroidal melanoma

Possibilities and limitations of radioimmunoscintigraphy and conventional diagnostic modalities in choroidal melanoma.

A prospective clinical study to assess the value of immunoscintigraphy with a monoclonal antibody (MoAb) against high molecular weight melanoma associated antigen (225.28S) was performed in 43 patients with choroidal melanoma; in six patients with a lesion suspected of being choroidal melanoma, and in seven patients with a benign lesion simulating a choroidal melanoma. The results of immunoscin...
