Purpose: This paper reports a case of pigmented conjunctival lesions after intravitreal injections in a patient who received brachytherapy for uveal melanoma.
Methods: Clinical and histopathological examination of the pigmented conjunctival lesions was performed.
Results: A 57-year-old male who was treated with brachytherapy for uveal melanoma developed radiation retinopathy. Following intravitreal anti-vascular endothelial growth factor (VEGF) injections, 2 pigmented conjunctival spots appeared at the injection sites. After excision of the lesions, histopathology showed pigment-loaded macrophages, with no signs of active tumour cells.
Conclusion: Two conjunctival lesions that appeared following uveal melanoma brachytherapy and anti-VEGF injections were excised under suspicion of tumour seeding. Histopathology, however, showed aggregates of pigment-loaded macrophages.
