Acne and oily skin are both associated with hirsutism. Androgen acts on the PSU to increase sebum production and has an important role in acne development. However, many cases of acne are not associated with hyperandrogenism.

Androgenic alopecia is another distressing condition associated with androgen excess. It is characterized by hair loss from the crown of the scalp sparing the frontal and occipital hairline (male pattern baldness). [37]

Acanthosis nigricans is a mucocutaneous condition where velvety hyperpigmentation patches appear mainly in the skin of the base of the neck, axilla, antecubital fossae, and groin. Acanthosis nigricans is a marker of insulin resistance. [38] In contrast, acanthosis nigricans is rarely seen with androgen secreting tumors. [39]
