BACKGROUND
Congenital aplasia of major salivary glands is a very rare entity, especially if it concerns an ipsilateral aplasia in a nonsyndromic patient.
KEY POINTS FROM THE CASE
The aim of this report is to present a case of an aplasia of the left submandibular gland, which was incidentally diagnosed during presurgical imaging for an ipsilateral sublingual ranula. Histopathological evidence of the lack of sublingual gland tissue in the excised specimen of the ranula is discussed.
MAIN LESSONS TO BE LEARNED FROM THIS CASE REPORT
Unilateral submandibular aplasia has unknown etiology. Clinicians should be aware of this condition mainly to be able to differentially diagnose a hypertrophy/dysplasia of the contralateral or other major salivary glands, or when xerostomia is the main patient's symptom.
背景
先天性大唾液腺发育不全是一种非常罕见的病症，尤其是在非综合征患者中出现同侧发育不全的情况。
该病例的关键点
本报告的目的是呈现一例左侧下颌下腺发育不全的病例，该病例在同侧舌下腺囊肿的术前影像学检查中偶然被诊断出来。文中讨论了在舌下腺囊肿切除标本中缺乏舌下腺组织的组织病理学证据。
从此病例报告中应吸取的主要经验教训
单侧下颌下腺发育不全的病因不明。临床医生应了解这种情况，主要是为了能够鉴别诊断对侧或其他大唾液腺的肥大/发育异常，或者当口干是患者的主要症状时。
