PURPOSE: To report an atypical case of occult uveal melanoma in a patient with oculodermal melanocytosis that first presented with symptoms of hepatic metastasis.
METHODS: A previously healthy 16-year-old boy with noted ocular hyperpigmentation developed abdominal pain and vomiting and was found to have a hepatic mass consistent with a metastatic lesion from an occult uveal melanoma.
RESULTS: On examination, the patient's visual acuity was 20/20, and pupils were reactive without an afferent pupillary defect in both eyes. Examination of the left eye revealed normal findings. In the right eye, conjunctiva was freely moving over hyperpigmented sclera. Dilated fundus examination demonstrated a hyperpigmented, minimally elevated, choroidal mass in the right eye. Results of fundus autofluorescence, IV fluorescein angiography, spectral-domain optical coherence tomography, and ultrasonography were suspicious for uveal melanoma. Genetic testing of the hepatic mass was positive for BAP1, confirming that the metastasis originated as uveal melanoma rather than cutaneous or intracranial melanoma. Magnetic resonance imaging of the brain and orbits showed negative impression for intracranial lesions. A PET scan revealed numerous additional metastatic lesions, and the patient was referred to palliative care.
CONCLUSION: Patients with oculodermal melanocytosis are at an increased risk for both uveal melanoma and subsequent metastasis, and frequent monitoring should be performed because treatment options for metastatic uveal melanoma are limited.
