Ulcerated NL predisposes patients to infections and very rarely is associated with malignant transformation, mainly to squamous cell carcinoma (SCC). We describe the case of a 68-year-old Caucasian male diagnosed with disseminated NL associated with type 2 diabetes mellitus (DM), presenting a SCC on an ulcerated plaque of NL located on the left forearm and chronic osteomyelitis of the radius.engjournal article10.1111/iwj.122061742-481X
