Abstract:
Melanomas on the foot are difficult to differentiate from
diabetic foot ulcers (DFU). In particular, acral lentiginous and amelanotic melanomas have a high chance of being misdiagnosed. We present two patients with diabetes
mellitus and malignant melanomas of the foot initially
diagnosed as DFU. Both cases were treated with wide
excision amputation and local dissection, without adjuvant
chemotherapy or radiotherapy. Both patients remain
disease-free up to the last follow-up visit. It is important to maintain a high index of suspicion and a skin biopsy should be done in any DFU with atypical features.
