Cyst of Duct of Krause's Gland.

CYSTS of Krause's glands usually occur as retention cysts in cicatricial conditions of the conjunctiva such as trachoma, or pemphigus (Stoewer, 1892; Thompson and Chatterton, 1905; Contino, 1960; Caocci, 1932) or after the scar caused by excision of chalazion (Paton, 1919). Giri (1936) and Butler (1907) reported cases wherein no conjunctival scarring was evident. The cysts occur in the upper fornix from distension of the duct, the result of blocking by inflammatory material (Wolff, 1951). A cyst of the duct of Krause's gland is so rarely reported in the ophthalmic literature (Duke-Elder, 1952) that a description of a new case may be of interest. Clinically it was diagnosed as a conjunctival cyst, and only histopathological examination revealed its true nature.
