We present the case of a 23-year-old man with a few weeks history of a gradually enlarging mass of the right submandibular region. On palpation, the well-defined swelling had an engorged and elastic consistency. Sonography revealed a sharply defined mass with spherical and solid echorich lesions surrounded by areas of liquid. Histological examination of the resected tumour revealed an epidermoid cyst. The wall of the cyst was composed of stratified squamous epithelium with the cystic space containing keratin arranged in layers. Characteristic sonographic findings of epidermoid cysts regularly permit accurate preoperative diagnosis without the need for additional imaging procedures.
我们报告一例23岁男性病例，其右下颌下区有一逐渐增大的肿块，病程数周。触诊时，边界清晰的肿胀质地饱满且有弹性。超声检查显示一个边界清晰的肿块，有球形实性回声病变，周围为液性区域。对切除肿瘤的组织学检查显示为表皮样囊肿。囊肿壁由复层鳞状上皮组成，囊腔内含有分层排列的角蛋白。表皮样囊肿典型的超声表现通常可在无需额外影像学检查的情况下进行准确的术前诊断。
