Dacryocystitis associated with malignant lymphoma of the lacrimal sac.
Ophthalmology 1993 May
BACKGROUND: Tumors of the lacrimal sac are unusual, and lymphomas of the lacrimal sac are quite rare. Four patients with a history of well-differentiated, small cell lymphoma or chronic lymphocytic leukemia presented with either acute or chronic dacryocystitis and epiphora due to lymphomatous infiltration of the lacrimal sac.
METHODS: All four patients underwent dacryocystorhinostomy with lacrimal sac biopsy. All tissues underwent complete histopathologic evaluation including immunohistochemical studies for cell surface markers and, in addition, were compared with previous biopsies performed for the initial diagnosis of lymphoma.
FINDINGS: All biopsies demonstrated small cell well-differentiated lymphoma on histologic and immunofluorescent examination. No patient demonstrated orbital involvement on computed tomography. One patient had previously diagnosed chronic lymphocytic leukemia and one patient demonstrated diffuse lymph node involvement on postoperative systemic evaluation. All four patients underwent additional chemotherapy. No recurrence of dacryocystitis or epiphora occurred.
CONCLUSION: Four patients presented with dacryocystitis secondary to lacrimal sac lymphoma. Lymphomatous lacrimal sac infiltration is an unusual cause of dacryocystitis. Biopsy of the lacrimal sac plays a diagnostically important role in dacryocystorhinostomy even in the absence of obvious tumorous involvement of the lacrimal sac mucosa.
