title: Dacryocystitis provoked by recurrence of extramedullary plasmacytoma of the orbit: a case report.
abstract: Extramedullary plasmacytoma (EMP) of the orbit is an extremely rare tumor, which frequently manifests with nonspecific symptoms. In the case reported, the symptoms of relapsing dacryocystitis appeared before the diagnosis of orbital EMP in a 60-year-old man. Moreover, EMP of the right submandibular gland that had been excised and treated by radiotherapy preceded the orbital lesion by seven years. The present report emphasizes the importance of an extensive medical workup to rule out multiple myeloma or other malignant lymphoproliferative diseases, because their treatment and prognosis are very different. Additionally, it is necessary to consider all tumors that can provoke relapsing dacryocystits.
