Diagnosis: Angiomyoma of the lacrimal drainage apparatus (LDA)
Angiomyomas are uncommon benign tumors with vascular and smooth muscle components. They are usually found on the skin of the extremities and are rarely found in the head and neck region.1Lacrimal sac tumors are rare entities as well. Patients often present with epiphora, recurrent dacryocystitis, and/or a lacrimal sac mass. These neoplasms of the lacrimal system are most commonly classified as either epithelial or nonepithelial.2,3We describe the first case (to our knowledge) of an angiomyoma presenting in the LDA.
