Lacrimal gland ductal carcinomas: Clinical, Morphological and Genetic characterization and implications for targeted treatment.

This study identified a spectrum of genetic events and pattern of protein expression in DC of the lacrimal gland similar to a subset of carcinomas of the breast and ductal carcinomas of the salivary glands. For therapeutic purposes, aberrations in several components of especially the HER2 signalling pathway could alleviate the effect of HER2-directed therapy illustrating an inadequacy of isolated HER2 testing.
