Primary ductal adenocarcinoma of the lacrimal gland.

Abstract

To report the case of a 59-year-old man with a right lacrimal gland mass, subsequently diagnosed as primary ductal adenocarcinoma of the lacrimal gland. Interventional case report. We report the clinical presentation, histopathologic and immunohistochemical features, and treatment of a patient with primary ductal adenocarcinoma of the lacrimal gland. The current literature regarding this uncommon neoplasm also is reviewed. Excisional biopsy revealed primary ductal adenocarcinoma of the lacrimal gland. The patient subsequently underwent extensive local resection of the tumor and is awaiting radiotherapy to the orbit and neck. A literature search revealed only 3 prior reports of primary ductal adenocarcinoma of the lacrimal gland. Although uncommon, primary ductal adenocarcinoma of the lacrimal gland displays characteristic histologic and immunohistochemical findings that allow its distinction from the other primary lacrimal gland adenocarcinomas. Awareness and recognition of this rare malignancy may aid in further delineation of its biologic behavior, management, and prognosis.
