A functioning epidermal melanin unit implies a melanocyte capable of transferring melanosomes to keratinocytes; this requires not only melanocytes with adequate dendrites but also "receptive" keratinocytes. Skin with incontinentia pigmenti was examined by electron microscopy. Premelanosomes were occasionally found within keratinocytes and deposits of extracellular granular material that came from vacuolar degeneration of keratinocytes adjacent to melanocytes.
一个功能正常的表皮黑素单位意味着一个能够将黑素小体转移至角质形成细胞的黑素细胞；这不仅需要具有足够树突的黑素细胞，还需要“有接受能力的”角质形成细胞。通过电子显微镜检查色素失禁症患者的皮肤。偶尔在角质形成细胞内发现前黑素小体，以及来自与黑素细胞相邻的角质形成细胞空泡变性的细胞外颗粒物质沉积物。
