- A case of sublingual dermoid cyst treated by transoral marsupialization
抄録
<p>Dermoid cyst is a cystic lesion mainly caused by migration of ectodermal tissue during the embryonic period and is most commonly observed at the midline of the oral floor. The contents of the cysts are well known to show a callus-like appearance composed of keratides and other tissue from subcutaneous organs, but this lesion often has serous or fatty fluid. Therefore, DC is difficult to diagnose on imaging alone because of various images on MRI. Enucleation is the first-line treatment for this disease, and marsupialization is not common. We report a case of a sublingual dermoid cyst which was successfully treated by marsupialization. The patient was a 53-year-old woman. She was referred to our hospital with the complaint of a mass on the oral floor. Contrast-enhanced CT showed a 24 × 23 × 22 mm spherical hypo-absorbable area extending from the midline of the floor of the mouth to above the hyoid muscle, and MRI showed a high signal on T1-weighted and a slightly low signal on STIR images, indicating lipoma. However, during biopsy we confirmed that it was a cystic lesion and temporal marsupialization was performed. The histopathological diagnosis was dermoid cyst, and excision was planned. However, the lesion shrank remarkably and the submucosal remnant tissue was excised four months after biopsy, and there were no histopathological findings indicating a dermoid cyst.</p>
