Mottle hyperpigmentation

Mottle hyperpigmentation (often referred to clinically as mottled hyperpigmentation) is a dermatologic sign characterized by irregular, patchy, or variegated macules of increased skin pigmentation Commonly affecting sun-exposed areas of the integumentary system—such as the face, neck, and dorsal hands—it predominantly arises in photoaged populations or as a component of postinflammatory dyschromia, though it can also manifest in certain hereditary reticulate pigmentary disorders

Pathophysiologically, the condition is driven by UV-induced or inflammatory stimulation of melanocytes, resulting in hyperactive melanogenesis, aberrant melanin synthesis, and the uneven accumulation of melanin within epidermal keratinocytes or dermal melanophages
