Fibro-osseous lesions represent a variety of bone proliferations each characterized by different morphologic patterns of osteoid production. Psammomatoid ossifying fibroma (POF) is characterized histologically by numerous small round ossicles resembling psammoma bodies and is a locally invasive lesion of facial and cranial bones. Two cases of POF arising in the ethmoid sinus and involving the orbit are presented to emphasize the importance of complete surgical removal of involved bones. Histologically, portions of POF may demonstrate other patterns of osteoid production, which resemble fibrous dysplasia and Paget's disease of bone. The variation in radiodensity in POF on computed tomography is a function of the density of psammomatoid ossicles and of the coexistence of other "minor" forms of bone proliferation.
纤维骨性病变代表了多种骨增殖，每种都以不同的类骨质生成形态学模式为特征。砂粒体样骨化纤维瘤（POF）在组织学上的特征是有许多类似砂粒体的小圆形骨小体，是一种侵犯面部和颅骨的局部侵袭性病变。本文报告两例起源于筛窦并累及眼眶的POF病例，以强调彻底手术切除受累骨骼的重要性。在组织学上，POF的部分区域可能表现出其他类骨质生成模式，类似于骨纤维异常增殖症和佩吉特骨病。POF在计算机断层扫描上的放射密度变化是砂粒体样骨小体密度以及其他“次要”骨增殖形式共存的结果。
