“…Furthermore, as in the patient reported by Caminiti et al. , 7 in whom KS was initially misdiagnosed as a diabetic plantar foot ulcer, the ulcer on the sole of the left foot in our patient could be considered as a manifestation of the disease. However, in the absence of histological examination, this is only a hypothesis.…”

A growing number of studies report dermal malignancies mimicking diabetic foot ulcers (DFUs). We reviewed clinical cases reporting malignant tumours misdiagnosed to be DFU aiming to identify factors contributing to misdiagnosis. We systematically searched in PubMed for clinical cases reporting on misdiagnosis of DFU in patients with cancer. A chi-square analysis was conducted to show the link between the incidence of initial DFU misdiagnosis and patient age, gender and wound duration. Lesions misdiagnosed to be DFU were subsequently diagnosed as melanoma (68% of the cases), Kaposi's sarcoma (14%), squamous cell carcinoma (11%), mantle cell lymphoma, and diffuse B-cell lymphoma (both by 4%). Older age (≥65 years) was associated with a significantly increased risk of malignancy masked as DFU (OR: 2.452; 95% CI: 1.132 to 5.312; P value = .019). The risk of such suspicion in older patients (age ≥ 65 years) was 145% higher than in younger patients (age < 65 years).Clinicians should maintain a high level of awareness towards potentially malignant foot lesions in elderly patients with diabetes (age ≥ 65).diabetic foot ulcer, malignancy, melanoma, misdiagnosis, skin cancer Key Messages• reports of diabetic foot ulcer (DFU) are increasing in number, and there are several accounts of malignancies misdiagnosed as DFU • the vast majority of malignancies misdiagnosed as DFU are melanomas (71%) • patients at ages above 65 years have more than twice (Â2.5) higher chance of DFU misdiagnosis

“…The two most common types of ulcerating skin tumours are basal cell carcinoma (BCC) and SCC [ 9 ]. There are case reports of other rarer skin cancer types imitating chronic leg ulcers, like cutaneous lymphoma [ 10 ], Kaposi’s sarcoma [ 11 ], eccrine porocarcinoma [ 12 ], and angiosarcoma [ 13 ]. Because of its rarity, malignant tumours as a cause of chronic leg or foot ulcers are often overlooked [ 14 ].…”

Our purpose was to collect data on the incidence of malignant skin tumours presenting as chronic leg or foot ulcers in a tertiary centre, and to analyse the frequency and type of initial clinical misdiagnoses in these cases. A retrospective chart review of cases with melanoma or other malignant neoplasms of the skin of the lower extremity treated in a tertiary centre during January 2010 until February 2020 was conducted to identify cases that presented as chronic ulcers. Out of 673 cases, 26 (3.9%) were identified with a total of 27 malignant tumours presenting as chronic ulcers of the lower leg or foot. Therefrom, seven were diagnosed as melanoma, eight as squamous cell carcinoma, and twelve as basal cell carcinoma. The mean interval until diagnosis for all tumour types was 44.4 months (median 24 months). A delay in correct treatment occurred in 12 out of 26 cases (46%) as a result of misdiagnosis with subsequent treatment as chronic leg or foot ulcers of a different etiology. Misdiagnoses were venous ulcer, traumatic wound, mixed arterial and venous ulcer, arterial ulcer, and ulcer of an unknown origin. Malignant ulcers presenting as chronic ulcers are rare, but often lead to misdiagnosis.
