Acquired hypertrichosis lanuginosa related to chemotherapy.
Hypertrichosis Lanuginosa

The presence of increased numbers of vellus hairs is called hypertrichosis lanuginosa. It may be either congenital (inherited AD or AR) or acquired. The acquired type is more common, occurs typically in adults, and is usually a sign of either malignancy or cytotoxic chemotherapy. Patients with acquired hypertrichosis lanuginosa (AHL) related to cancer usually have advanced disease and the prognosis tends to be poor. Lung, colon or breast cancers have most commonly been associated. There is a female predominance.


For the acquired type, simple shaving may be done.

For the congenital type, there is a case report of a young girl treated with diode laser depilation since the age of 9 months. It was well tolerated, and neither general nor local anesthesia was needed. A reduction of approximately 80% of facial and body hair was achieved [PD 2012 Oct 2.].
