The rarity of a supernumerary caruncle prompted Stephenson,1 who is credited with the first description of the condition (1896), to make the following remark : ". . . I was unaware that the caruncle, like the tragus, mamma, or nipple, was subject to reduplication." The second case on record is that of Schreiber2 (1913), and then follow 2 cases reported by Feigenbaum3 (1931). The present communication is written with the intention of adding a fifth case, in which there was a double reduplication.
The characteristic location of the supernumerary caruncle is just behind the inferior punctum, on the tarsal conjunctiva. It thus lies close to the normal caruncle but is not connected with it. Grossly the tissue possesses a somewhat granular surface, with the yellowish subepithelial mottling which is conspicuous in the natural caruncle. Lanugo hairs may be readily observed. The mass is not quite as large as the parent caruncle
