食物颗粒经常会在口腔的不同部位受到撞击。口腔脉冲肉芽肿是由于植物或蔬菜来源的食物颗粒植入口腔组织而形成的。病变可能是中央的或周围的。它具有不同的组织学表现，可能与许多其他病变（包括寄生虫感染）相混淆。受影响的植物物质很少与多发性骨髓瘤、细菌和真菌骨髓炎以及鳞状细胞癌相关，并且以前从未在文献中报道过。因此，在本病例系列中，我们讨论了上述三种罕见的关联以及与根尖肉芽肿和根尖囊肿相关的脉搏肉芽肿。本文旨在讨论病例的临床、组织学和偏光显微镜特征以及证实病因学和鉴别诊断的理论。版权所有：© 2024 Journal of Oral and Maxillofacial Pathology。

Food particles get frequently impacted in the oral cavity in varying sites. Oral pulse granuloma develops as a consequence of implantation of food particles of plant or vegetable origin in oral tissues. The lesion might be central or peripheral. It has a differing histological picture and may be confused with many other lesions including parasitic infection. Impacted vegetable matter is rarely associated with multiple myeloma, bacterial and fungal osteomyelitis, and squamous cell carcinoma and has never been reported in the literature before. Thus, in the present case series, we have discussed about the above three rare associations along with pulse granulomas associated with periapical granuloma and periapical cyst. The paper aims to discuss the clinical, histological, and polarising microscopic features of the cases and theories substantiating aetiology and in general about the differential diagnosis.Copyright: © 2024 Journal of Oral and Maxillofacial Pathology.
