[Hyperplasias of mucous, sebaceous and lacrimal glands and of blood vessels at the caruncula lacrimalis (author's transl)].

A caruncular swelling with light brown pigmentation suggests a compound or junctional nevus. A proliferation of mucous cells is very often found inside this nevus (cases 1 and 2). A yellowish lobular tumor of the caruncle is found in hyperplasia of the sebaceous glands (case 3). Adenomata of the lacrimal glands and oncocytomata may be of a glazed reddish color (case 4), whereas a red caruncle suggests a hemangioma (case 5).
