Apocrine adenocarcinoma arises from the sweat glands of the body, which are densely located in the axillae, areola and nipple of breast, ear canal, perianal area, and external genitalia.1 Ocular adnexal apocrine adenocarcinoma is a rare tumour that arises from glands of Moll and therefore presents as an eyelid mass.2 However, these sweat glands are also present in the caruncle region of the eye. We present a rare case of rapidly progressing primary apocrine adenocarcinoma of the caruncle in an elderly male.
