This is the report of an 80-year-old patient with diffuse brownish hyperpigmentation and velvety thickening of the skin with onset 1 year before. Warty lesions on his limbs were present as well as papillomatous and verrucous lesions on his lips, mouth and eyelid conjunctivae with hyperkeratosis of the nipples. Biopsies, performed at different sites, showed histological pictures consistent with a diagnosis of acanthosis nigricans (AN) with florid cutaneous and mucosal papillomatosis. This type of AN is frequently associated with internal malignancy. In our patient serum levels of tissue polypeptide antigen, carcinoembryonic antigen, cytokeratin fragment and squamous cell carcinoma antigen were high and chest computed tomography scan indicated a large tumour infiltrating the right lung and extending to the mediastinum. Cytological examination of bronchial drainage revealed the presence of neoplastic cells, non-small cell type carcinoma. The most frequent cancer associated with malignant AN is gastric adenocarcinoma. Lung tumour has rarely been reported with AN. Malignant AN is sometimes associated with other cutaneous and mucosal warty lesions, as in our patient. These various skin and mucosal lesions are the expression of a systemic epithelial disorder and may help clinicians to suspect a malignant form of AN.

19-year-old hirsute woman with obesity, skin lesions with features of acanthosis nigricans around neck, armpits, thoracic cage and wrists escalating for couple of months, elevated testosterone and insulin plasma levels was admitted to hospital to perform diagnostic approach. The final diagnosis was hyperandrogenism-insulin resistance-acanthosis nigricans syndrome (HAIR-AN syndrome), considered as a subtype of policystic ovary syndrome (PCOS) and impaired glucose tolerance. HAIR-AN is characterized by coexistence of: hyperandrogenism (HA), insulin resistance (IR) and acanthosis nigricans (AN). These symptoms are result of increased insulin and androgens levels. Due to accompanying complications (obesity, hyperglycemia, hyperlipidemia, infertility) patients with HAIR-AN syndrome should be monitored and treated. Rarely acanthosis nigricans, especially when occurs rapidly and extensively, may be a paraneoplastic disorder. Life style modification with BMI reduction was recommended and metformin, a drug improving sensitivity to insulin, was administered. Patient should be monitored due to possible complications of obesity, diabetes and hyperinsulinemia.
