Dominika Kwiatkowska1, Adam Reich1
Forum Dermatologicum 2021;7(4):113-115.


Acanthosis nigricans is a skin disease characterized by hyperpigmented plaques, typically located in axillae, groins, inframammary region, neck, and flexor surface of the skin. Numerous systemic disorders may lead to the development of acanthosis nigricans. Here a case of a patient with acanthosis nigricans and tissue resistance to insulin is presented. Moreover, the usefulness of dermoscopy as an additional tool that can help to establish a proper diagnosis is discussed.
