Spontaneous regression of conjunctival keratoacanthoma


An 83-year-old white man presented with a rapidly growing conjunctival mass in his left eye over the course of 1 month. While awaiting surgical intervention, the tumour underwent partial, spontaneous regression to half its original size. The lesion was ultimately excised with wide margins using a no-touch technique and application of cryotherapy to the corneal and conjunctival margins and scleral bed. Histopathological analysis revealed a conjunctival keratoacanthoma. To our knowledge, this is the first case documenting the partial, spontaneous regression of a conjunctival keratoacanthoma over a 5 week time course from the time of diagnosis to surgical excision.
