Final answer:
Melasma, also known as Chloasma Gravidarum, typically appears on the face during pregnancy. It is characterized by blotchy, brown patches and is caused by increased production of melanin due to hormonal changes.
Step-by-step explanation:
Melasma, also known as Chloasma Gravidarum, often occurs during pregnancy and predominantly affects the face. This condition manifests as blotchy, brown patches principally on the cheeks, forehead, nose, or upper lip. It is a result of increased melanin production stimulated by higher levels of melanocyte-stimulating hormone and estrogens during pregnancy. Although less common, melasma can also present on other parts of the body that are exposed to the sun.
While Melasma is often referred to as the "mask of pregnancy," it is important to distinguish it from other skin changes that can occur during pregnancy, such as the linea nigra, which forms a line of pigment from the umbilicus to the pubis. Additionally, it's crucial to note that not all skin changes are benign. The ABCDE mnemonic can help identify early-stage melanoma, a serious skin cancer. If any suspicious lesions resembling the descriptions of melanoma are found, it's essential to consult a doctor for proper diagnosis and management.
