Basal cell carcinoma presented and mistreated as chronic venous ulcers - report of five cases

Introduction. Basal cell carcinoma (BCC) is the most common non-melanoma skin cancer in Caucasians and one of the most frequent malignancies in general, especially in older adults. Squamous cell carcinoma is the most frequent tumor developing on chronic leg ulceration, while BCC rarely occurs and is often misdiagnosed. In addition, since older adults commonly have coexisting chronic vein insufficiency, the ulcerated BCC is frequently mistaken as being of venous origin. Outlines of cases. We present five cases of BCC presenting as chronic venous ulcers. Conclusion. Long-lasting ulcers with no healing tendency must be considered malignant until proven otherwise. Knowing the characteristics of malignant ulceration may help in early detection and treatment.
