Diagnosis of Occult Melanoma Using Transient Receptor Potential Melastatin 1 (TRPM1) Autoantibody Testing: A Novel Approach – Corrected Proof
Purpose: To report the first case of melanoma-associated retinopathy (MAR) and underlying occult melanoma diagnosed based on the presence of serum transient receptor potential melastatin 1 (TRPM1) autoantibodies.Design: Interventional case report with basic science correlation.Participants: One patient with MAR.Intervention: Testing for the presence of serum TRPM1 autoantibodies.Main Outcome Measures: Diagnosis of an occult melanoma involving the axillary lymph nodes (unknown primary site) and MAR based on the presence of TRPM1 autoantibodies in the patient's serum.Results: The patient's clinical exam was remarkable for mild intraocular inflammation in both eyes and retinal hemorrhages with an apparent choroidal neovascularization in the left eye, (Read more...)
