Acral melanoma presenting with lung invasion, and a gigantic inguinal metastatic mass

Although malignant melanoma is a rare type of skin cancer, it accounts for most skin cancer-related deaths. Foot lesions may be ignored by both patients and clinicians and could therefore lead to advanced disease. An acral melanoma may also be confused with a pressure ulcer and result in a late diagnosis. The need to perform a skin biopsy should therefore be considered when dealing with protracted wounds. In this report, we present the case of an 84-year-old female patient with malignant melanoma, which was diagnosed late, recurred in the same area following surgery, and caused lung metastasis and a giant inguinal mass.
