Abstract

In branchial lymphoepithelial cyst (BLEC), which is also known as branchial cleft cyst, the remnants of a branchial arch develop into a cyst, causing swelling. The first case of BLEC in the parotid gland was reported by Hildebrant in 1895. Since then, BLEC in the parotid gland has continued to be reported, but in rare cases. A 45-year-old man presented to our hospital with a swelling of the left cheek of approximately 6 months' duration. The patient underwent a superficial parotidectomy and was pathologically diagnosed with BLEC. Of note, this was the first case of non-human immunodeficiency virus (HIV)-related BLEC of the parotid gland in South Korea. BLEC is a benign condition, but its treatment depends on the presence of HIV infection. In HIV-negative patients, BLEC does not require a further work-up to evaluate metastasis. Our case report describes the diagnosis and treatment of BLEC in a patient without HIV.
