Non-healing ‘diabetic’ ulceration which turned out to be a lentiginous melanoma: a case from a diabetic foot clinic

摘要

There are currently 425 million of people with diabetes worldwide1 and diabetic foot disease affects approximately 6% of them.2 Any skin lesion in a person with a history of diabetes should be, however, reviewed with an open mind and with awareness of possible differential diagnoses. This becomes particularly relevant in cases with an apparent discrepancy between the duration of diabetes, level of metabolic control and presence/absence of other microvascular complications on one side and presence of a non-healing ‘diabetic’ ulceration on the other.
