Ultrastructurally, irregular distribution of melanocytes with heterogenous distribution of melanosomes within keratinocytes has been observed.36 In photoaged skin, both benign hyper- and hypopigmented lesions and malignant lesions are seen. Ultrastructurally, some of the melanocytes have normal melanogenic activity and contain numerous melanosomes while others contain only immature melanosomes.
