title: In situ adenocarcinoma ex pleomorphic adenoma of the lacrimal gland.
abstract: A case of an in situ adenocarcinoma of the lacrimal gland that developed in a recurring pleomorphic adenoma is presented. Six years after incomplete resection of a pleomorphic adenoma, the patient complained of a progressive swelling of her right upper eyelid without pain or diplopia. An orbital computerized tomography scan showed an inhomogeneous mass in the right lacrimal gland region without bone involvement. After local excision of the in situ adenocarcinoma ex pleomorphic adenoma, the tumour has been in control for over 6 years.
