What is a Preauricular mass?
We recently treated a rare case of angioleiomyoma of the preauricular area. Angioleiomyoma is a benign tumor arising from smooth muscle within blood vessel walls. These tumors can arise anywhere in the body; however, they are usually found in the lower extremities and present as a painful mass.
What are Preauricular tags?
Preauricular tag; Preauricular pit. An ear tag is a small skin tag or pit in front of the outside part of the ear. Many normal children are born with ears that are less than perfect and that may stick out. However, low-set ears, absent pinna, and abnormal folds can be associated with various conditions.
