Acquired hypertrichosis lanuginosa. A case report

A 62-year-old, postmenopausal woman had rapidly appearing lanugo-type hair on her face and extremities. Adenocarcinoma of the colon was diagnosed. The patient underwent partial hemicolectomy and liver biopsy. Serum androgen levels were normal. Carcinoembryonic antigen and alpha-fetoprotein were undetected. These cases are rare, and acquired hypertrichosis lanuginosa can be a clinical tumor marker.
