骨化性脂膜炎四例报告及文献复习

骨化性脂膜炎为皮下组织的反应性骨生成性病变。作者１９７８～１９９４年收治４例，均发生在趾末节。临床上均有疼痛，趾甲下肿胀、溃烂、溢脓、皮肤暗红等表现。２例作了Ｘ线检查见趾末节软组织内有密度增高阴影。病理检查，病变呈扁圆形，与骨皮质可分离，切面灰白色有砂砾感。组织相４例类同，即皮下脂肪组织萎缩，代以骨样组织及新生骨小梁，其中２例有软骨形成，背景为小血管和成纤维细胞增生及炎细胞浸润。本病仅拔去趾（指）甲作单纯刮除易复发，切除完全可治愈。临床、Ｘ线和病理诊断上易误诊为甲沟炎或肿瘤。

Panniculitis ossificans and review of the literature

Four cases of panniculitis ossificans were treated in 1978-1994. They all occurred at the distal phalanx. Pain, swell beneath nails, ulcer, pyorrhea, clark red skin were observed. X-ray examination of 2 cases showed dense shadows in the solft tissue of the distal phalanx. Pathologically the lesion was flatten-round, and separated with the bone. The cut surface was gray and sandy. Histological pictures were the same in 4 cases, namely atrophy of subcutaneons adipose tissue, the osteoid and new bone were seen. Two cases formed the cartilage and the background showed small vessels, proliferative fibroblasts, and inflammatory cells. This disease is easy to recur when nail extraction with curretting is done. It is usually misdiagnosed as inflammation of nail bed or tumor.
