Case Report: A rare and recurrent case of primary corneal keratosis: diagnostic and therapeutic challenges

This case describes a rare presentation of primary recurrent corneal keratosis with benign histopathological features but clinically aggressive behavior. The rapid and persistent recurrence despite conservative management highlights the limitations of superficial debridement and suggests the presence of subclinical disease within the lesion base. This report underscores the need for long-term surveillance and consideration of more definitive treatment strategies for similar recurrent keratotic lesions on the cornea.
