Skin Lesions and Diagnosis Skin acts as window in several ways. Two examples: Point mutations may cause skin and internal change. Birt-Hogg-Dube Syndrome causes cutaneous fibrofolliculomas, renal tumors, and spontaneous pneumothorax by affecting the folliculin gene. Hormonal overdose causes skin and internal change. PCOS causes elevated androgens -> acne, hirsutism and also hyperinsulinemia -> acanthosis nigricans and diabetes

Prior treatment, of home or physician source, and the diagnosis(es) based on. Other drugs, herbal remedies, ethnic medications. Effect of sunlight, season, contact with immediate environment (plants, animals, chemicals, metals). Role of physiologic changes (menses, pregnancy).

Skin Lesions and Diagnosis Why do experienced clinicians often view the rash before taking a history? Visual diagnosis may be sharper without preconceived ideas. Some lesions and patterns are so distinctive that history is needed only as confirmation. In other cases the rash guides and interacts with the history, allowing one to diagnose more efficiently.
