This case report highlights the importance of recognizing cutaneous epidermoïd carcinoma in chronic intertrigo, indicating the need for early diagnosis.
An 80-year-old diabetic woman presented with chronic intertrigo of the 3rd and 4th interdigital spaces of the left foot. She was treated with local and general antifungals without improvement. Dermatological examination revealed a fissured, painless intertrigo with infiltration of the edges. A skin biopsy confirmed the diagnosis of cutaneous epidermoïd carcinoma, and onco-dermatological treatment was initiated with good progression. Cutaneous epidermoïd carcinoma is a malignant skin tumour with a fairly guarded prognosis, requiring appropriate management, starting with early diagnosis. Our case is a reminder that the diagnosis of cutaneous epidermoïd carcinoma should be made in the presence of any chronic skin lesion, no matter how trivial, especially if it does not respond to the usual treatment.
