Skin cancer does not occur in a vacuum. Patients may have skin lesions that mimic malignancy clinically and/or histologically such as hypertrophic lichen planus or cutaneous lupus. When you are seeing a patient with skin cancer you will often be asked about co-existent inflammatory skin disease such as eczema, psoriasis, and tinea. Co-existent skin disease may influence your management. For example a patient with facial rosacea and solar keratoses may not tolerate field treatments such as 5-Fluorouracil cream, Imiquimod, or Ingenol.
These articles explore various aspects of non-malignant skin disease. We hope you find them interesting.
