Abstract
Benign lymphoid hyperplasia (BLH) is a rare type of lymphoproliferative disease of the oral mucosa. The present study reports a 61-year-old man who presented to the hospital with a soft polyp formation in the left buccal mucosa. He was suspected with a granuloma from cracked tooth, and an excisional biopsy was performed under local anesthesia. The histopathological examination of the specimen confirmed BLH. The patient's condition was well and free of disease at 2 years after the surgery. In this present case study, we concluded that BLH may be considered as a differential diagnosis of lymphoid disease in the oral soft tissue.
Highlights

Summary
A 61-year-old man was referred to the Division of Dental and Oral Surgery, Kimitsu Chuo Hospital, with complaints of a soft polyp formation in the left buccal mucosa. At the beginning, he thought of this lesion as vesicle cause of a burn. There was no change in the symptom for 1 month, and he remained anxious about this polyp. A painless/soft swelling of 11 × 8 mm in diameter with well-demarcated margins and an intact mucosa (Figure 1) was observed
