Photomicrograph of case 2 shows an intradermal nevus at low magnification (Fig. 3A, HE × 40). The architectural and cytological maturation gradient was evident at higher magnification with superficial nevus cells in theque formation without intracellular melanin (3B, HES × 100), cells in the middle zone, with only melanin in some isolated nevus cells (3C, HES × 100) and deeper nevus cells appear elongated and spindle shaped without intracellular melanin (3D, HES × 100).
