Hypertrichosis

Excessive, non-androgen-dependent hair growth in areas not typically hairy for age, sex, and ethnicity. Unlike hirsutism, which is excess male-pattern hair growth in women. Possible causes are congenital (congenital hypertrichosis lanuginosa, Ambras syndrome, Cantú syndrome, Rubinstein-Taybi syndrome) or acquired (minoxidil, cyclosporine, phenytoin), malignancy (paraneoplastic syndrome), hypothyroidism, severe malnutrition, anorexia nervosa, chronic skin inflammation, and topical casts/corticosteroids.
