Correct Answer - C
Ans. C. Histologically there is hypermelanosis
Acanthosis nigricans is brown to black discolouration which usually
affects body folds like axilla, groin, umblicus, forehead.
Acanthosis nigricans occurs in individuals younger than 40 years of age.
It is associated with obesity (most common); endocrinopathy like
insulin resistance DM, hypothyroidism, Bloom synd., PCOD, and internal malignancy e.g. gastric adenocarcinoma.

Histopathologically, Papillomatosis is the characteristic feature
whereas there is no hypermelanosis.
