[Immunohistochemical and Molecular Genetic Profile of Mantle Cell Lymphoma of the Lacrimal Gland: A Case Series of an Uncommon Tumour of the Lacrimal Gland].

LG-MCL show an immunohistochemical profile corresponding to the classical profile of MCL. Overexpression of molecules for target therapies was found in all cases (CD20 for rituximab, BCL2 for Bruton-kinase-inhibitors and CD19 for CAR-T cell therapy). The removal of the GL can potentially drive to severe complications, even if aimed to confirm diagnosis. Therefore, the choice between GL-biopsy and exstirpation should be carefully evaluated, especially in cases of suspected lymphoma.
