Two cases of blue nevus of the uterine cervix were studied ultrastructurally. Both were incidental findings in hysterectomy specimens. The pigmented cells were characterized by both solitary and compound melanosomes at different stages of development and by basement membrane surrounding the interdigitated cytoplasm. The evidence suggests that the pigmented cells in uterine blue nevus may be Schwann's cells with melanin synthesis.
