Preferred Label : Acquired hypertrichosis lanuginosa;
ICD-11 definition : Patients with hypertrichosis lanuginosa acquisita grow lanugo-type (ie, fetal) hair
near their eyebrows and on their forehead, ears, and nose. Some patients have extensive
involvement that includes the extremities, axillae, and trunk, but the palms, soles,
and perineum are spared. The hair, referred to as malignant down, is fine, thin, and
unpigmented, unlike the robust pigmented terminal hairs characteristic of hirsutism.
Although acquired hypertichosis may be provoked by other diseases or drugs, the presence
of otherwise unexplained acquired hypertrichosis lanuginosa acquisita should prompt
an extensive search for occult malignancy.;
