Abstract

Introduction: Dermoid cysts are benign cystic teratomas with epithelial lined cavities, bearing hair follicles, hair, sebaceous glands, sweat glands, and occasionally tissues derived from the mesoderm. Dermoid cysts of the floor of the mouth are relatively rare but when they occur, are commonly restricted to one anatomic zone and in the midline region. They are treated surgically. Case Report: We present a case of a lateral dermoid cyst mimicking a plunging ranula extending from the upper part of the neck, on the right side, upwards into the sub-mandibular region and via a hiatus in the mylohyoid muscle into the floor of the mouth, in a 24-year-old Ghanaian male. Conclusion: The treatment of dermoid cysts of the floor of the mouth is surgical, using either an intraoral, extra oral or both approaches depending on the localization

Highlights

Dermoid and epidermoid cysts are benign cystic teratomas with epithelial lined cavities, bearing hair follicles, hair, sebaceous glands, sweat glands, and occasionally tissues derived from the mesoderm [1, 2]
We present a case of large lateral dermoid cyst that had been present since birth with an oral, submandibular as well as upper cervical component, in a 24-year-old male patient, and discuss an intraoral approach to its successful surgical management
Histopathological examination with hematoxylineosin staining revealed a cystic lesion with a stratified squamous epithelium lining; with sebaceous glands and hair follicle in wall, and a fibrovascular connective tissue capsule covering the cystic lumen consistent with dermoid cyst (Figure 5)

Summary

INTRODUCTION

Dermoid and epidermoid cysts are benign cystic teratomas with epithelial lined cavities, bearing hair follicles, hair, sebaceous glands, sweat glands, and occasionally tissues derived from the mesoderm [1, 2] They usually present early in life as asymptomatic masses with slow and progressive growth, and may reach large sizes, involve more than one anatomical area and or may abut the hyoid bone when in the neck [1]. We present a case of large lateral dermoid cyst that had been present since birth with an oral, submandibular as well as upper cervical component, in a 24-year-old male patient, and discuss an intraoral approach to its successful surgical management. Histopathological examination with hematoxylineosin staining revealed a cystic lesion with a stratified squamous epithelium lining; with sebaceous glands and hair follicle in wall, and a fibrovascular connective tissue capsule covering the cystic lumen consistent with dermoid cyst (Figure 5)
