          Abstract

          Background

          There are limited reports of uveal “melanocytic” lesions in patients with oculocutaneous albinism, with no reports from Asia.

          Objectives

          In this study, we report 3 eyes with uveal “melanocytic” lesions in Asian patients with oculocutaneous albinism.

          Methods

          Retrospective small case series. Three eyes of 2 Asian patients with oculocutaneous albinism were included. Case 1 was a 54-year-old female who presented with juxtapapillary choroidal melanoma and underwent enucleation. Case 2 was a 39-year-old male with pigmented choroidal nevus in the right eye and suspicious nevus/choroidal variegation in the left eye.

          Results

          For case 1, metastatic workup including ultrasound of the abdomen, liver function test, and chest X-ray was unremarkable. Magnetic resonance imaging of the cranium ruled out extraocular extension. The left eye was enucleated due to the large tumor size and poor visual potential, and histopathological examination confirmed the diagnosis of choroidal melanoma with mixed cell type. At the last follow-up 6 months after enucleation, there was no evidence of metastasis. Case 2 was observed.

          Conclusion

          Pigmented choroidal nevus and melanoma are rarely observed in patients with oculocutaneous albinism.

            Choroidal malignant melanoma in an albino.

            This is the first report of an amelanotic melanoma arising in the unpigmented choroid of a tyrosinase-positive oculocutaneous albino (TPOCA). Melanosomes within the tumour showed a maturation arrest in the unpigmented type II (premelanosome) phase. Other neural crest derived melanocytes in iris and choroid showed similar limited melanogenesis. The neuroectodermally derived melanocytes of the iris, ciliary body, and retinal pigment epithelium (RPE) contained mature melanosomes, though clinically the RPE was pale. The significance of this tumour arising in an albinotic eye is discussed.

              Dermatoscopy of pigmented melanocytic nevi in patients with oculocutaneous albinism.

              Oculocutaneous albinism is a group of rare inherited disorders of pigmentation. Some albinos may have a certain degree of melanin production and, consequently, may develop pigmented lesions during their lives. Albinos are also at great risk for developing cutaneous malignancy, including melanomas. We report two patients with oculocutaneous albinism and pigmented melanocytic nevi and describe, as far as we known, for the first time the dermatoscopic findings in albinos' nevi. The predominant dermatoscopic pattern observed in pigmented melanocytic nevi in albino patients seems to have a similar pattern to that observed in nevi of patients with skin type I. It corresponds to light-brown coloration, reticular pattern, and central hypopigmentation.
