Which term describes skin discoloration that can occur during pregnancy?

Chloasma is the term specifically used to describe the skin discoloration that commonly occurs during pregnancy, often referred to as the "mask of pregnancy." This condition is characterized by brown patches or spots, usually developing on the face, and is a result of increased melanin production triggered by hormonal changes throughout pregnancy.

While hyperpigmentation is a broader term that includes any darkening of the skin, chloasma is more specific to the hormonal changes associated with pregnancy. Dermatosis is a general term for skin diseases or disorders and does not describe a specific condition related to pregnancy. Ecchymosis refers to discoloration caused by bleeding underneath the skin, often due to trauma or injury. Therefore, chloasma is the precise term that accurately describes the pregnancy-related skin changes.
