The answer is B. (Acanthosis nigricans)
Acanthosis nigricans is associated with hyperpigmented areas that typically affect flexural folds (axilla). The two basic types of acanthosis nigricans are benign and malignant.
-The benign form is associated with obesity, diabetes, Stein-Leventhal syndrome, Cushing's disease, Addison's disease, pituitary disorders, and hyperandrogenic syndromes. Drugs, including glucocorticoids, nicotinic acid, diethylstilbestrol, and growth hormone therapy, have also caused acanthosis nigricans. Many cases are idiopathic.
-Malignant acanthosis nigricans is associated with an intestinal cancer such as gastric carcinoma.
