The effects of hyperinsulinemia on serum testosterone, progesterone, dehydroepiandrosterone sulfate, and cortisol levels in normal women and in a woman with hyperandrogenism, insulin resistance, and acanthosis
nigricans in association with adenocarcinoma from an unknown primary site.
The most common histopathologic features are hyperkeratosis, acanthosis
, and papillomatosis.
For example, acanthosis
nigricans deserves special attention in Hispanics, 5% of whom are insulin resistant, compared with 1% of the overall population, said Miguel R.
The clinical examination was significant for widespread acanthosis
nigricans and mild lipomas, as was the cardiac examination.
All these samples exhibited hyperplasia of the squamous epithelium with acanthosis
, parakeratosis, and hyperkeratosis.
If menarche does not start in an appropriate time frame, or if the girl starts to develop signs of hirsutism, weight gain, or acanthosis
nigricans (darkening of the skin folds), she should be evaluated for an androgen problem.
Freeman (14) reviewed the potential pathogenetic evolution of PEH, concluding that the epidermal hyperplasia could be a reflection of continued growth of entrapped surface epithelium or, alternatively, a manifestation of appendageal acanthosis
Another flag for NAFLD in obese children is acanthosis
2 Once a major criterion is met, the presence of any 2 of the following warrants blood glucose level screening: (1) family history of type 2 diabetes in first-degree or second-degree relative; (2) Native American, African American, Latino, Asian American, or Pacific Islander ethnicities; (3) presence of acanthosis
nigricans, hypertension, dyslipidemia, or polycystic ovary syndrome.
His unfunded pilot study of the insulin-sensitizing agent in six affected teens showed that the drug restored menstrual regularity reduced high serum insulin and androgen levels, resulted in weight loss and reduction in body mass index, and improved hirsutism and acanthosis
The epithehum was hyperkeratotic, with areas of acanthosis
Histologic features include hyperkeratosis, papillomatosis, acanthosis
, and squamous cell differentiation without koilocytosis.
More than 60% have acanthosis
nigricans as physical evidence of insulin resistance.
Eczema is a pattern of inflammatory response of the skin with a perivascular infiltrate of lymphocytes around upper dermal vessels, associated with spongiosis and varying degrees of acanthosis
