A Case of Dermoid Cyst of the Floor of the Mouth with Profuse Pus Discharge

Abstract

Dermoid cysts of the head and neck are relatively rare. We recently treated a patient with dermoid cyst of the floor of the mouth with profuse purulent discharge.
The patient is a 27-year-old actress who visited our hospital complaining of severe pain and swelling in the left submandibular region. During treatment with intravenous injection of antibiotics, a profuse purulent discharge appeared in the floor of the mouth. The inflammation subsided gradually, and the clinical course was favorable. After the inflammation had cleared completely, the remaining cyst-like lesion was resected via an external approach through the left submandibular region under general anesthesia. The histopathological diagnosis was dermoid cyst. When a cyst in the floor of the mouth is punctured for diagnotic or therapeutic purposes, early surgical removal is recommended to avoid the problems of inflammation which may occur due to contamination.
