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.
