Hypertrichosis
Congenital
• Hypertrichosis lanuginosa, possibly due to an autosomal dominant mutation on 8q;
• Generalised hypertrichosis, due to an autosomal dominant mutation on chromosome x24-q27.1;
• Terminal hypertrichosis, possibly linked to a mutation in MAP2K6 on chromosome 17;
• Circumscribed hypertrichosis;
• Localised hypertrichosis;
• Nevoid hypertrichosis.

Acquired
• Hypertrichosis lanuginosa, linked to cancer, endocrinopathies and therapeutic drugs;
• Generalised hypertrichosis;
• Patterned hypertrichosis;
• Localised hypertrichosis.
