[Adenocarcinoma of the meibomian gland with invasion of the orbit].

Adenocarcinoma of the meibomian glands is a tumor with atypical glandular features, that appear initially as a chalazion formation and then invades the neighbouring tissues. The patient, a 63 years old woman, presents a chalazion at the level of the left lower eyelid, which, after developing for a year, stars bleeding and infiltrates the ground of the inferior sac and the orbit. The tumoral formation makes a common body with the eyeball and the cornea, which, lacking protection, becomes opaque. Removal of the ulcerous eyelids is performed, with partial exenteration of the orbit. Anatomopathological investigation show the diagnosis: adenocarcinoma of the meibomian glands. Adenocarcinoma of the meibomian glands is the most malignant palpebral tumor. The signs of malignity are: infiltrated and relapsing aspect of the chalazion in on aged person, with low sebaceous secretion in the presence of pigmentations and bleedings in the tumor.
