ABSTRACT
Aim: The aim of this study is to describe an unusual case of an Epidermoid Cyst (EC) of the tongue treated by a Potassium Titanium Phosphate (KTP) laser. Presentation of Case: A 38 young male patient came to our attention since a little painless swelling, yellowish, on the lateral left side of the tongue. After an accurate clinical examination, a surgical excision with a KTP laser was performed. Control at 7 and 21 days showed a complete healing of lesion and the histological diagnosis was EC. Discussion: EC generally appear like a firm, usually painless swelling that sometimes raises the tongue. In the differential diagnosis of the EC the clinician has to consider a wide range of pathologic conditions that could be classified as development, neoplastic and infective pathologies. Surgical enucleation is the only effective treatment for these kinds of lesions and prognosis is very good, with a very low incidence of relapse. Conclusion: Several techniques are reported in the literature but the use of KTP laser for the excisional biopsy of ORAL EC is very effective, since the relative ease and speed of execution, the compliance of patience, the absence of bleeding and suture.
