How Do You Spell EXTRANEOUS PIGMENTATION?

1. Extraneous pigmentation refers to the presence of pigment in areas or on surfaces where it is not typically found, or where it is considered abnormal or unwanted. Pigmentation generally refers to the coloration of tissues in an organism caused by the deposition or production of pigment. However, in the context of extraneous pigmentation, it specifically refers to pigmented areas that are considered excessive or unrelated to the normal distribution.

   In biology, extraneous pigmentation can occur due to various factors, such as abnormal melanin production or deposition, exposure to certain substances, or as a result of disease processes. For instance, in humans, extraneous pigmentation could manifest as dark patches or spots on the skin that are unrelated to normal skin pigmentation patterns. These pigmented areas may be caused by conditions like hyperpigmentation, melasma, or certain skin disorders.

   The term "extraneous" implies that the pigmentation is superfluous or beyond what is expected or desired. It suggests that the pigmentation is not part of the natural or typical appearance of the area or surface affected. Extraneous pigmentation can often be aesthetically displeasing or may signify an underlying health condition that requires medical attention. Consequently, treatments or interventions may be sought to reduce or eliminate the excess pigment and restore a more normal appearance.

2. Discoloration of the skin or tissues by a pigment introduced from without, as in argyria.
