Generalized lipodystrophy syndromes, including the congenital Berardinelli-Seip and acquired Lawrence syndromes have also been associated with AN. Both syndromes involve the complete absence of subcutaneous fat causing extreme insulin resistance and hyperandrogenism. Acanthosis nigricans may also occur with polycystic ovary syndrome or in a triad with polycystic ovaries and hirsutism. In the latter clinical triad, the vulva is the most commonly affected area of the body. yo obese female with type V hyperlipidemia and nicotinic acid-induced AN on antecubital fossae and axillae Fabroni, C1, Gimma, A, Cardinali, C, Lo Scocco, G. “Tripe palms associated with malignant acanthosis nigricans in a patient with gastric adenocarcinoma: a case report and review of the literature”. Dermatol Online J. vol. 18. 2012 Nov 15. pp. 15 (Underlines the important relationship between malignant AN and Tripe palms and their association with underlying malignancy.) An important consideration when evaluating a patient with AN is the potential for psychological distress. In one study, obese female adolescents with AN showed significantly lower self-esteem status than the healthy control. Testosterone levels significantly correlated with poor self-esteem scores among the obese females with AN. 37 While correction of underlying causes remains the mainstay of treatment, it is important to consider cosmetic options to improve patient quality of life that may be affected by the presence of AN lesions.

At the risk of overgeneralizing, in my experience there are two types of patients with acanthosis nigricans (AN) — those who are devastated by it, and those are unaware that they have it. Excess insulin causes skin cells to reproduce at a rapid rate. For people with skin that has more pigment, these new cells have more melanin. This increase in melanin produces a patch of skin that’s darker than the skin surrounding it. Insulin crosses the dermal- epidermal junction and, in high concentrations, can have growth-stimulating effects through its binding to type 1 insulin-like growth factor receptors (IGFRs) on keratinocytes. This stimulates the proliferation of these cells, leading to acanthosis nigricans.

Acta Derm Venereol. vol. 89. 2009. pp. 435-7. (Researchers from the Department of Dermatology at the Univerisity of Tokushima Graduate School and Ehime University School of Medicine in Japan compared the expression of fibroblast growth factor receptor 3 (FGFR3) in two cases of malignant AN to that in 20 samples of normal skin using immunohistochemical analysis. The epidermis demonstrated a strong expression of FGFR3 in both cases of malignant AN while FGFR3 immunoreactivity was negative to moderately positive in normal epidermis.) First impressions count. In fifth grade, my class was assigned Ernest Hemingway’s Pulitzer Prize winning Old Man and the Sea. I was bored silly and vowed never to read his work again. Decades later, when visiting Papa Hemingway’s cat-riddled study in Key West, it occurred to me that I was rather presumptuous and may not have had the maturity to recognize genius. I bought a copy of For Whom the Bell Tolls — his depiction of guerilla warfare of the Spanish Civil War is the most riveting writing I have ever read. My initial impression of retinoids for AN may have also been presumptuous. I plan on giving topical retinoids another try, and especially look forward to utilizing trifarotene, when available.

Allantoin– Allantoin is a natural compound found in plants such as comfrey and chamomile. Allantoin is known for its ability to promote skin healing by stimulating cell growth and regeneration. This can be particularly helpful for people with Acanthosis Nigricans, as it can help to improve the appearance and texture of the affected skin. Associated drugs include (but are not limited to) nicotinic acid lotion, fusidic acid ointment, subcutaneous insulin, oral contraceptives, oral corticosteroids, hormones (diethylstilbesterol, testosterone), triazinate, and aripiprazole.

PubMed The severity of AN has a positive correlation with fasting insulin levels. 3 AN is likely the result of high levels of insulin binding to insulin-like growth factor 1 receptors (IGF-1Rs) on keratinocytes and fibroblasts. This leads to a proliferation of both cell types and clinically apparent plaques and papillomatosis. 3 In addition, high levels of insulin increase the amount of circulating free IGF-1, which results in keratinocyte growth and differentiation. Treatment for AN depends on the cause. If AN is due to an underlying condition, such as diabetes or a hormonal condition, treating the condition will treat the skin problems.

Obesity associated AN is more common in adulthood with patients who weigh almost double their body weight. 2. Benign Genetic Acanthosis Nigricans Abrupt onset in a thin individual should alert the physician to the possibility of an underlying malignancy; prompting an appropriate history, examination, and investigations. Age-appropriate malignancy screening should be performed in patients with suspected malignant AN. Rapid onset of skin lesions in patients over the age of 40 should alert clinicians that malignancy may be the cause of AN. The most commonly associated malignancy is gastric adenocarcinoma and the majority (60%) of patients present with concomitant skin lesions and malignancy. Malignant AN has also been reported with endometrial carcinoma, lung cancer, hepatocellular carcinoma, pancreatic adenocarcinoma, ovarian carcinoma and squamous cell carcinoma of the cervix. The course of AN correlates directly with the associated malignancy; therefore, skin lesions should resolve with its eradication. Treatment Options
