Sublingual Swelling Masquerades a Ranula: A Case Report and Review of the Literature

Epidermoid cyst in the floor of mouth is a very rare non-neoplastic cyst lined by squamous epithelium. Here is a case report of a 17-year-old female who presented with a slow growing swelling in the floor of mouth with difficulty in breathing and swallowing from past 4 months. A clinical diagnosis of ranula was made. Biopsy and subsequent histopathological evaluation revealed it as epidermoid cyst. Thus, epidermoid cyst of the floor of mouth can mimic ranula in its clinical presentation. Therefore, histopathologic evaluation is critical in making definitive diagnosis in such scenarios. A detailed account of clinical, radiological and histopathological evaluation has been presented.
