Clinical experience on diagnosis and treatment for malignancy originating from the dacryocyst

To summarize clinical experience on the diagnosis and treatment for malignancy originating from the dacryocyst.

We retrospectively analyzed clinicopathological data from 12 cases that were diagnosed with malignancy originating from the dacryocyst by histopathological examination in our hospital from 2007 to 2017.

Of the 12 cases with malignancy originating from the dacryocyst, 7 were male and 5 were female, with a mean age of 53 years (range, 4-81). Clinical manifestations included a mass in the dacryocyst area in 12 cases, epiphora in 9 cases, pyoid tears in 2 cases, bloody tears in 3 cases, and redness and swelling in the dacryocyst area in 2 cases. Lymphoma occurred in six cases, malignant melanoma in three cases, embryonal rhabdomyosarcoma in one case, and squamous cell carcinoma in two cases.

Misdiagnosis and missed diagnosis readily occur for malignancy originating from the dacryocyst because its clinical manifestations are diverse. For the suspected patients, it is necessary to perform related examinations. Individualized treatment should be adopted based on pathological types and specific conditions.
