A lesion which appeared clinically consistent with a ranula was explored surgically and found to represent a dilated submandibular duct. The differential diagnosis of cystlike swelling in the floor of the mouth should include sialolithiasis, mucous retention phenomenon (mucocele, ranula), dermoid and epidermal inclusion cyst, thyroglossal duct cyst, branchial cleft cyst, hemangioma, lymphangioma, cystic hygroma, lipoma, and occasionally pleomorphic adenoma. The case presented here demonstrates, both clinically and histologically, the cystic appendix-like appearance of a dilated submandibular duct manifest at birth. Reference is made to the limited number of similar cases noted in the relevant literature.
一个临床上看似与舌下囊肿相符的病变接受了手术探查，结果发现是扩张的下颌下腺导管。口腔底部类囊肿性肿胀的鉴别诊断应包括涎石病、黏液潴留现象（黏液囊肿、舌下囊肿）、皮样囊肿和表皮样囊肿、甲状舌管囊肿、鳃裂囊肿、血管瘤、淋巴管瘤、囊状水瘤、脂肪瘤，偶尔还包括多形性腺瘤。本文所呈现的病例在临床和组织学上均显示出出生时就存在的扩张下颌下腺导管的囊状阑尾样外观。文中提及了相关文献中记录的此类相似病例数量有限。
