Case history
Case history #1
A 70-year-old previously healthy white man presents with multiple, hyperkeratotic, scaly papules on the face, scalp, and hands. Some papules have grown to become larger nodules that sometimes bleed and fail to heal. In the past he has had significant sun exposure including multiple blistering sunburns. Previously, he had skin cancer on his face.
Case history #2
A 60-year-old white woman presents with an enlarging scaly pink plaque on her forearm that is friable and bleeds easily. She has been taking cyclosporine for 4 years following a kidney transplant.
Other presentations
May also present as a nonhealing wound, often attributed to trauma by the patient. Bowen disease (SCC in situ) may be misdiagnosed as dermatitis that fails to respond to treatment.
