  "abstract": "Background: Atypical lipomatous tumor/well-differentiated liposarcoma is a rare, low-grade, locally aggressive malignant adipocytic neoplasm, particularly uncommon in the head and neck region and oral cavity.\n\nCase presentation: Here, we report a case of atypical lipomatous tumor in a 58-year-old Iranian female presenting with a recurrent submucosal mass on the right buccal mucosa, initially misdiagnosed twice as a myxoid lipoma over a 10-year period.\n\nConclusions: This case underscores the diagnostic challenges of atypical lipomatous tumor in uncommon sites, such as the buccal mucosa, highlighting the importance of awareness about variable microscopic features of this rare neoplasm to prevent misdiagnosis and also it`s uncommon aggressive behavior despite low-grade nature. We emphasize early and accurate diagnosis of this tumor and long-term follow-up of the patient maybe inhibit late-stage complications.",
