Simultaneous Occurrence of a Midline Sublingual Dermoid Cyst with Respiratory Epithelium and Submental Dermoid Cyst in a Paediatric Patient: A Case Report and Review of Literature
To present the case of a simultaneously occuring sublingual dermoid cyst with respiratory epthelium and a submental dermoid cyst, and also to review literatures on the same.
A complete examination, radiograph, MRI and excision biopsy of both lesions were carried out and diagnosis was arrived at histopathologically.
The histopathology of the submental swelling revealed orthokeratinized stratified squamous epithelium with underlying connective tissue consisting of dense irregularly arranged collagen fibres with fibroblasts along with chronic inflammatory cell infiltrate of lymphocytes and plasma cells. There was presence of sebaceous glands and sebum. Sublingual swelling showed non-keratinized stratified squamous epithelium with a fibrovascular connective tissue. Areas of pseudostratified ciliated columnar epithelium were also evident in some areas. Presence of sebaceous glands also seen. Based on these findings a confirmatory diagnosis of sublingual dermoid cyst with respiratory epithelium and submental dermoid cyst was made.
This report throws light on midline lesions of the oral cavity and hopes to add this rare case into the current differential diagnosis of the same.
