肩胛骨骨纖維發育不全病例報告

Osteofibrous Dysplasia in the Scapula: A Case Report

骨纖維發育不全是纖維發育不全中少見的種類，別名又叫作骨化纖維瘤或Campanacci氏病灶，通常侵犯的部位是脛骨。骨纖維發育不全好發於20歲以下的男性，如果發生在成年人則通常不會造成臨床問題且會自行消失。骨纖維發育不全的病理特徵是纖維母細胞增生伴隨骨小島以及有成骨細胞鑲邊，除了有成骨細胞鑲邊外其餘病例特徵上與纖維發育不全類似。此次我們報告1例發生在30歲男性肩胛骨的骨纖維發育不全。

Osteofibrous dysplasia, also known as ossifying fibroma or Campanacci lesion, is a rare form of fibrous dysplasia which usually affects the tibia. The lesion usually affects children younger than 20 years old with a predominance among males. The lesions usually regress and do not cause problems in adulthood. Its pathology features are similar to those of fibrous dysplasia except there is also osteoblastic rimming. In osteofibrous dysplasia, there is a proliferation of fibroblasts with surrounding islands of woven bone and osteoblastic rimming. Herein we report a rare case of osteofibrous dysplasia over acromion and scapula in a thirtyyear- old male.
