There was initial response to wound size with standard treatment including offloading, debridement and antibiotic therapy. However, subsequently, there was no progress noted. Incidentally, two small black spots in the wound bed raised the suspicion of melanoma. Incisional biopsy confirmed acral lentiginous melanoma (ALM). The final diagnosis was ALM coexisting with diabetic foot ulcer (DFU). The wound was treated by surgical resection and flap reconstruction that resulted in complete healing. Fourteen months after the initial intervention, the patient developed a new lump and ulceration around the previous wound bed. This turned out to be recurrent disease with distant metastasis. The patient died eventually with palliative support. Through this case, we would like to highlight the importance of early biopsy and intervention in DFU especially for those wounds with atypical presentation or refractory to standard treatment.
