摘要：

Objective: The aim of this report was to review oral follicular lymphoid hyperplasia, with emphasis on palatal lesions. Method and materials: A comprehensive search was performed on PubMed for case reports and case series of palatal follicular lymphoid hyperplasia published in the English language literature. Relevant data from collated articles was sought, including patient demographics, clinical manifestations, imaging modalities and findings, comorbidities, etiopathogenesis, lesional management, and lesional outcome. A new palatal case has also been provided to illustrate several features of this lesion. Results: In total, 32 cases were assembled to establish clinicopathologic correlations, representing the largest aggregation of published cases. Most of the affected patients were at least 60years old and with a decisive female predilection. The majority of lesions were s3cm, appearing as normal color, purple -red or red, and varied from soft to firm. Notably, 32% of palatal follicular lymphoid hyperplasias were associated with denture wear, and lesional recurrence was recorded in 16% of cases. To date, none of the reported cases of palatal follicular lymphoid hyperplasia has undergone malignant transformation. Conclusions: Palatal follicular lymphoid hyperplasias often arise as a reactive process. Critical histopathologic and histochemical assessments are necessary to establish benignity. Postoperatively, clinicians should follow patients for at least 5years for recurrence and remain vigilant for neoplastic change as several published accounts of non -oral follicular lymphoid hyperplasias have undergone malignant transformation, usually to lymphoma.
