New frontiers in endovascular therapies for locally advanced hepatocellular carcinoma

Transcatheter arterial infusion chemotherapy and embolization for primary lacrimal sac squamous cell carcinoma: A case report

BACKGROUND

Although tumors of the lacrimal sac are rare, they represent a potentially life-threatening situation that can easily be overlooked since patients present with features consistent with chronic dacryocystitis. Lacrimal sac squamous cell carcinoma is the most common lacrimal sac malignancy, but no definitive treatment is currently available.

CASE SUMMARY

We describe a 34-year-old unmarried male who presented with a red and swollen right lower eyelid, which gradually developed into a mass of the lower eyelid that obstructed vision in his right eye. He was treated with transcatheter arterial infusion chemotherapy and interventional embolization based on the tumor characteristics, and we also administered intensity-modulated radiotherapy and targeted therapy after tumor shrinkage. The tumor treatment demonstrated good efficacy, and the patient’s condition was stable after 10 mo of follow-up.

CONCLUSION

To our knowledge, this is the first report of lacrimal sac squamous cell carcinoma treated with transcatheter arterial infusion chemotherapy and interventional embolization, which might expand clinical treatment options for lacrimal sac carcinoma.
