Acquired ichthyosis from breast cancer.

Non-metastatic skin manifestations of malignant disease are well recognized (Med. Clin. N. Amer., 1965). They include acquired ichthyosis, which is not uncommon in association with malignant lymphomas (Sneddon, 1955) but is rare in patients with cancer. Van Dijk (1963) described one case with lung cancer and from the literature collected 28 others associated with malignant disease, only one being cancer, and this was of the breast. A case is described of disseminated breast cancer and acquired ichthyosis.
