Abstract

Salivary duct cyst (SDC) is a rare reactive lesion of the salivary gland ducts and is infrequently reported in minor intraoral glands, particularly the lower lip. We describe a 49-year-old man with a painless, well-circumscribed submucosal swelling of the lower lip. Clinical findings suggested mucocele or salivary gland tumor, and excisional biopsy revealed a cyst lined by thin cuboidal epithelium adjacent to salivary gland lobules, confirming SDC. The lesion was completely removed, and no recurrence has been observed. Furthermore, a review of English-language literature from PubMed, Scopus, and Web of Science shows that intraoral SDCs typically affect middle-aged adults, demonstrate slight female predominance, and present as soft, mucosa-colored swellings with variable histopathologic patterns, including occasional epithelial metaplasia. Surgical excision remains the preferred management, with recurrence considered rare, although follow-up is recommended. This case underscores the need to include SDC in the differential diagnosis of atypical lip swellings.
