case_images: On slit-lamp examination, a large conjunctival lesion with variegate pigmentation and indistinct margins was detected on the superonasal part of the bulbar conjunctiva of the left eye (Figure 1).
case_images: Results of anterior segment optical coherence tomography of conjunctival nevus. B scan images (a, b) show distinct posterior borders of various parts of the lesion with variegate degree of posterior shadowing and with numerous intralesional cystic lesion (b); C scans (c-e) can detect intralesional cysts (c) and intralesional vessels (d, e).

case_images: Variegate severity of posterior shadowing and multiple intralesional cysts were detected on B scans, whereas C scans revealed the presence of intralesional cysts and intratumoral vascularity (Figure 2).
case_images: Histological examination revealed nevus cell nests with vertical maturation tendency and junctional activity in the epithelial-stromal border of the conjunctiva. Multiple cysts and intratumoral vessels could also be detected (magnification: (a) 10x, (b) 20x).
