Patient A 67-year-old man suffered from a tumor of the right upper eye
lid. Initially a chalazion was suspected, but the lesion developed cen
tral indentation and infiltrated the whole eyelid within three weeks.
Methods A biopsy was taken in another clinic. A keratoacanthoma was di
agnosed, however a squamous cell carcinoma could not be excluded defin
itely. Because of enlargement of the tumor and ulceration of the lid m
argin we removed the tumor completely with reconstruction of the eyeli
d. After one year no recurrence was observed. Conclusion A lid lesion
of this size has not been described in the literature.
