Focal Hyperpigmentation

Meaning

Focal hyperpigmentation refers to the clinical presentation of darkened patches of skin that are localized to specific, discrete areas of the body. This condition is characterized by an excessive deposition of melanin, the primary skin pigment, within the epidermis or dermis. While many factors can contribute, in the context of hormonal health, it is frequently associated with conditions like melasma or Addison’s disease, where hormonal dysregulation stimulates melanocyte activity. Understanding the distribution and pattern of this pigmentation is crucial for identifying the underlying systemic or endocrine etiology.
