Diabetic ulcer with cutaneous squamous cell carcinoma: A case report.

BACKGROUND

Chronic skin ulcers are a risk factor for the development of skin tumors. In patients with diabetes, chronic refractory ulcers may also contribute to higher susceptibility to skin tumors. Timely surgical removal of chronic and nonhealing diabetic foot ulcers can effectively prevent progression to squamous cell carcinoma. Such cases may be misdiagnosed owing to currently insufficient clinical evidence. However, in cases of chronic ulcer wounds, it is crucial to enhance clinical awareness regarding their potential progression into malignant lesions.

CASE SUMMARY

An 84-year-old male patient with diabetes presented with a significantly ulcerated area on his foot. The ulcer had been present to varying degrees since 1996. Between 2012 and July 2019, even after receiving treatments such as herbal medicines or heat clearance and detoxification complete healing of the wound was not achieved. In July 2020, histopathological analysis confirmed a well-differentiated cutaneous squamous cell carcinoma. After the treatments, the ulcer wound healed slowly and did not expand.

CONCLUSION

Potentially malignant lesions in chronic ulcer wounds should be identified and treated in a timely manner to prevent their progression.
