• Achromatosis — A generalized pathological condition characterized by the total absence or severe diminution of normal pigmentation within a tissue, organ, or the entire organism. In dermatology, the term describes severe states of cutaneous depigmentation (such as extreme forms of albinism or vitiligo universalis) where cells no longer produce melanin.
• Achromia — The total congenital or acquired absence of normal pigmentation of the skin, hair, or other tissues, caused by the lack or destruction of melanocytes and melanin production. This general medical term covers manifestations such as generalized albinism or completely white patches occurring in advanced vitiligo.
