Marjolin's ulcer associated with ulceration and chronic osteomyelitis.

This report describes a 78-year old male patient with a chronic venous ulcer on his left leg for the past 24 years, complicated by a squamous-cell carcinoma. After staging of the disease, the treatment administered was amputation of the leg above the knee. Marjolin's ulcer consists of the malignant transformation of a chronic ulcerative lesion. It is a relatively rare phenomenon. The malignant tumor most commonly described in the literature is squamous cell carcinoma, followed by basal-cell carcinoma, sarcoma and melanoma. The pathogenesis of Marjolin's ulcer remains to be fully clarified.
