Epidermoid Cyst: Case Report of an Unusual Location.

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.

Excision of oral mucocele by different wavelength lasers.

Background: Mucocele is a common benign neoplasm of oral soft tissues and the most common after fibroma. It generally occurs in the lower lip and its treatment includes excision of cyst and the responsible salivary gland, in order to prevent recurrences. Aims: To evaluate the capability of three different lasers in performing the excision of labial mucocele with two different techniques. Materials and Methods: In the presented cases, excision was performed using two different techniques (circumferential incision technique and mucosal preservation technique) and three different laser wavelengths (Er,Cr:YSGG 2780 nm, diode 808 nm, and KTP 532 nm). Results: All the tested lasers, regardless of wavelength, showed many advantages (bloodless surgical field, no postoperative pain, relative speed, and easy execution). The most useful surgical technique depends on clinical features of the lesion. Conclusion: Tested lasers, with both techniques, are helpful in the management of labial mucocele.
