Glandular odontogenic cyst (GOC) is a rare odontogenic cyst typically found in the anterior mandible and, in rare cases, the anterior maxilla, characterized by asymptomatic, slow-growing swelling. It mimics other odontogenic cysts and tumors, complicating the diagnosis. Histologically, GOC features mucus-producing cells and gland-like structures, initially suggesting a salivary gland origin. However, the absence of salivary gland markers and the presence of hybrid lesions with other odontogenic tumors confirm its odontogenic nature. Known for its aggressive behavior, GOC can cause significant growth and bone perforation, leading to high recurrence rates. This case report discusses a 34-year-old male with a recurrent cystic lesion initially misdiagnosed as a periapical abscess. Accurate diagnosis and successful management involved root canal treatment and surgical intervention, highlighting the importance of precise diagnosis and prompt treatment.
