Acanthosis nigricans (AN) results from epidermal keratinocyte stimulation and dermal fibroblast proliferation secondary to increases in insulin, insulin-like growth factor, and other aspects that ... Acanthosis nigricans is a skin condition characterised by a velvety papillomatous overgrowth of the epidermis. Darkening and thickening (epidermal hyperplasia) of the skin occurs mainly in the flexural areas, particularly the axillae, groin, inframammary region, and neck.
