Choroidal Melanoma

Fulminant hepatic failure due to metastatic choroidal melanoma

De novo Evolution of a Small Choroidal Melanoma.

AIM To report the evolution of a de novo choroidal melanoma. METHOD This is a case report of a 22-year-old white male patient who has been undergoing periodic examination for a choroidal 'freckle' since 10 years of age. RESULTS In 2007, a fundus photograph of the left eye showed a nondescript area of choroidal hyperpigmentation temporal to the fovea. Progressive growth was observed and, by ...

Association between choroidal pigmentation and posterior uveal melanoma in a white population.

BACKGROUND/AIMS It is well known that light skin pigmentation is a risk factor for cutaneous melanoma. The aim of this study was to investigate the analogous association between choroidal pigmentation and posterior uveal melanoma. METHODS Cross sectional study of 65 consecutive patients diagnosed with posterior uveal melanoma (melanoma group) and 218 consecutive patients referred for general ...

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...

Choroidal hemangioma: MR findings and differentiation from uveal melanoma.

BACKGROUND AND PURPOSE The aim of this study was to establish the MR imaging characteristics of choroidal hemangioma and to compare them with those of uveal melanoma. METHODS Among 41 patients examined at 1.5 T (4-cm surface coil, T1-weighted and fast spin-echo T2-weighted sequences), 25 had uveal melanoma and 16 had circumscribed choroidal hemangioma. After i.v. bolus injection of gadopentet...
