A 42 years old man presented with a painless increasing swelling in the region of the proximal phalanx and metacarpal bone of the ring finger persistent since five months. Plain X-rays revealed increased soft tissue density. The possibilities of differential diagnostic of tumors in the region were discussed because essential for the correct procedure. Histology revealed a bizarre periostal osteochromatic proliferation (Nora lesion). This rare lesion must be distinguished from an periostic osteosarcoma.
一名42岁男性患者，自五个月以来，其无名指近端指骨和掌骨区域出现无痛性进行性肿胀。X线平片显示软组织密度增加。由于正确的诊断程序至关重要，因此讨论了该区域肿瘤的鉴别诊断可能性。组织学检查显示为奇异的骨膜骨化性增殖（诺拉病变）。这种罕见的病变必须与骨膜骨肉瘤相鉴别。
