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.1 Lacrimal 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.2-3 We describe the first case (to our knowledge) of an angiomyoma presenting in the LDA.
Angiomyomas, also known as vascular leiomyomas or angioleiomyomas, typically form in the subcutis on the lower extremities and are composed of numerous thick-walled vessels. They account for approximately 5% of benign soft-tissue tumors and tend to be solitary and small (<2 cm) and enlarge slowly over time. They are painful about 50% of the time.
