[An unusual eyelid tumor (author's transl)]

A 68-year-old man presented with a rapidly growing upperlid tumor which due to multiple recurrences was excised 5 times within 4 years; and ultimately invaded the orbit. An orbital exenteration was performed. The unusual clinical course and the A-Scan sonographical findings of this tumor were most probably due to its uncommon histological features which proved to be an undifferentiated squamous cell carcinoma with features of Epithelioma metatypique intermediaire Darier.
