Acquired ichthyosis in a patient with adenocarcinoma of the breast.

Acquired ichthyosis and cutaneous metastases occurred in a 59-year-old black woman with adenocarcinoma of the breast. Acquired ichthyosis has been associated with "solid" tumors such as carcinomas of the lung, colon, and breast in only a few cases. Systemic diseases, medications, and malignancies associated with acquired ichthyosis are reviewed, and the need for a thorough clinical investigation of patients with acquired ichthyosis is stressed.
