This case emphasises the importance of a diagnostic biopsy. A panel of immunohistochemical markers is essential to make the correct diagnosis of AFX and distinguish it from malignant fibrohistiocytoma and non-keratin expressing squamous cell carcinoma. It usually follows a benign course, but can occasionally demonstrate aggressive local recurrence as well as distant metastasis. Invasion beyond the dermis and a rapid rate of recurrence are suggestive of a more aggressive clinical course. Paraffin fixed sections are preferred over frozen section techniques for this tumour. Medial canthal AFX has not been reported previously.
