A 24-year-old patient is described who had a 4-year history of pain in the right upper arm, with distinct night pain, that responded to salicylates. From the findings on conventional radiography, bone scintigraphy and MRI a multifocal osteoid osteoma was suspected, with one focus in the cancellous region of the greater tuberosity and a second cortical focus at the proximal humeral diaphysis. The resection "en bloc" of both tumors and histological examination confirmed the diagnosis. The patient was painfree after the curative resection of the two osteoid osteomas. Osteoid osteoma is a frequently found benign bone tumor, accounting for approximately 11% of cases. In rare cases a multicentric occurrence has been described. A possible occurrence of more than one osteoid osteoma in a single bone, not verified histologically, has been reported only three times in the literature. In patients with scintigraphic and radiographic findings of two foci, discrete synchronous multifocal osteoid osteomas should be suspected.
本文描述了一名24岁患者，其右上臂疼痛4年，夜间疼痛明显，服用水杨酸盐后症状缓解。根据传统X线摄影、骨闪烁显像和MRI检查结果，怀疑为多灶性骨样骨瘤，其中一个病灶位于大结节的松质骨区域，另一个皮质病灶位于肱骨近端骨干。对两个肿瘤进行“整块”切除并进行组织学检查，确诊了该诊断。在对两个骨样骨瘤进行根治性切除后，患者疼痛消失。骨样骨瘤是一种常见的良性骨肿瘤，约占病例的11%。在罕见情况下，曾有过多中心发生的描述。文献中仅报道过3次在单一骨中可能出现不止一个未经组织学证实的骨样骨瘤。对于有两个病灶的闪烁显像和X线摄影表现的患者，应怀疑为离散性同步多灶性骨样骨瘤。
