■治疗口腔下或底部无痛或无症状的肿块时,应考虑舌下表皮样囊肿。尽管它的不规则性,防止恶性转化对于成功的结果至关重要。
■皮样和表皮样囊肿很少见于头颈部。它们占所有口腔囊肿的不到0.01%。这是25岁男性口腔舌下表皮样囊肿的罕见病例。患者表现为持续1个月的无痛性舌下肿胀。临床检查显示,舌下区域延伸至the下三角形的非招标性肿胀。磁共振成像证实舌下间隙有6.2×7.7×3.2cm囊性病变。细针穿刺细胞学检查证实皮样囊肿内容物。全麻下口内手术切除成功。组织病理学分析显示,囊壁由分层鳞状上皮衬里。突出的颗粒层和角蛋白片的存在证实了表皮样囊肿的诊断。术后恢复良好,随访期间未见复发。此病例强调了一例巨大的舌下表皮样囊肿的罕见和不寻常的表现,并促进了人们对该领域患者护理的认识和潜在研究。
UNASSIGNED: When treating a painless or asymptomatic mass in the submental or floor of the mouth, sublingual epidermoid cyst should be considered. Despite its irregularity, preventing malignant transformation is essential for a successful outcome.
UNASSIGNED: Dermoid and epidermoid cysts are rarely found in the head and neck region. They account for less than 0.01% of all oral cavity cysts. This is a rare case of a sublingual epidermoid cyst of the oral cavity in a 25-year-old male. The patient presented with a painless sublingual swelling for a duration of 1 month. The clinical examination revealed a non-tender swelling in the sublingual region extending to the submental triangle. Magnetic resonance imaging confirmed a 6.2 × 7.7 × 3.2 cm cystic lesion in the sublingual space. Fine needle aspiration cytology confirmed dermoid cyst contents. Intra-oral surgical excision under general anesthesia was performed successfully. Histopathological analysis revealed that the cyst wall was lined by stratified squamous epithelium. The presence of a prominent granular layer and keratin flakes confirmed the diagnosis of an epidermoid cyst. Postoperative recovery was good, and no recurrence was observed during follow-up. This case emphasizes the infrequent and unusual presentation of a case of a giant plunging sublingual epidermoid cyst and promotes awareness and potential studies in the enhancement of patient care in this area.
