Peripheral odontogenic fibroma (POdF) is a rare benign odontogenic neoplasm. It represents the soft tissue counterpart of central odontogenic fibroma. The embryonic source of POdF has been suggested by many as arising from the rest of dental lamina that has persisted in the gingiva following its disintegration. It presents clinically as a firm, slow growing and sessile gingival mass, which is difficult to distinguish with more common inflammatory lesions. Very few cases of recurrence have been documented. It has been stated that histological budding of basal cell layer of the surface squamous epithelium is associated with higher recurrence and the presence of calcification in direct apposition to the epithelial rest is associated with lower recurrence. Hereby, we present a case which histologically exhibited budding of the basal cell layer, which could have been the reason for its recurrence.
外周性牙源性纤维瘤(POdF)是一种罕见的良性牙源性肿瘤。它是中央性牙源性纤维瘤的软组织对应物。许多人认为POdF的胚胎来源是牙板剩余部分,牙板在解体后仍存在于牙龈中。临床上它表现为质地坚硬、生长缓慢的无蒂牙龈肿物,很难与更常见的炎性病变相鉴别。记录在案的复发病例非常少。有人指出,表面鳞状上皮基底细胞层的组织学芽生与较高的复发率相关,而与上皮剩余直接相邻的钙化的存在与较低的复发率相关。在此,我们报告一例组织学表现为基底细胞层芽生的病例,这可能是其复发的原因。
