An invasive squamous cell carcinoma (ISCC) of the ankle: A case report

One to ten percent of all squamous carcinomas are invasive squamous cell carcinomas (ISCC), a rare variation of the disease. According to a recent literature review, less than 25 cases have been reported in the foot and ankle, making it especially uncommon in those areas.The authors present the case of a male patient, 60 years old, who presented with a progressive mass on his left ankle for 2 years with a history of healed burns in that area. The ISCC was diagnosed using histopathology after which he underwent a marginal excision biopsy and split-thickness skin grafting. Wide-marginal excision and split-thickness skin grafting were done. It was noted that the graft had taken well and that there were clear tumour margins postoperatively. The skin graft was almost completely incorporated. No tumour cells were reported on the margins during the postoperative histopathology.This case highlights a successful outcome of the patient improved at the 12-month follow-up, and he expressed a high degree of satisfaction with the treatment.ISCC of the lower extremities is a rare disease that almost never affects the ankle and is frequently treated inappropriately since it mimics chronic wounds. It is important to have an index of suspicion in patients with a history of chronic irritation to the area of interest. Surgery is the primary option if ICCS is detected. Clear tumour margins are important, and, if done well, excision should be curative.
