: The etiology of skin integrity disorders of the lower extremities can be very diverse. In addition to common diagnoses such as venous ulcers with ischemic etiology, decubitus ulcers and diabetic foot syndrome, ulceration of a malignant etiology must also be considered. Malignant melanoma is one of the most dangerous forms of skin cancer and, although rare, may cause foot lesions. The most frequently encountered type of melanoma on acral parts of the limbs is the rare acral lentiginous variant, which only occurs in 2-10% of all melanoma types. Clinical manifestation ranges from cutaneous surface erosion to ulceration with surrounding hyperkeratosis, which can cause considerable differential diagnostic difficulties in the management of patients with non-healing foot wounds. This paper aims to present a clear case study of a Caucasian female with chronic leg ulceration that resulted in a final diagnosis of malignant acral lentiginous melanoma. Supplemental theoretical information regarding the diagnosis and treatment of malignant melanoma has also been included in the report. Malignant acral lentiginous melanoma is a rare cause of non-healing wounds, but it must be considered in cases with long-term healing complications. Precise diagnostic deliberation is crucial in the management and treatment of all chronic and long-term non-healing lesions, and appropriately performed biopsies are essential to determine whether malignancy is the primary cause....
