Eruptive lentiginosis in a young healthy woman—Revisiting causal associations

Lentigines are hyperpigmented macules, which represent the simplest form of increased melanocytic proliferation. The term “lentiginosis” is applied for the presence of lentigines in an exceptionally large number or in a distinctive configuration. Lentigines evolve slowly, but widespread occurrence over a short period of time is typical of eruptive lentiginosis. We report an unusual case of eruptive lentiginosis in a female patient with no prior systemic disorder or familial pattern, presenting with widespread hyperpigmented macules, symmetrically distributed over the face, neck, upper trunk, shoulders, and both arms and forearms. Clinicohistopathological features were consistent with eruptive lentiginosis. Our case report seems interesting as well as a rare one as it involved an otherwise healthy young woman.
