A 70-year-old man underwent Tc-methylene diphosphonate scintigraphy for staging of adenocarcinoma prostate. Scintigraphy revealed diffuse increased tracer uptake in skeletal system along with faint renal visualization, a pattern compatible with metastatic superscan. The scintigraphy also revealed increased radiotracer uptake in the body of the mandible-Lincoln sign or black beard sign. Radiological imaging revealed sclerotic lesions throughout the skeleton including the mandible, confirming widespread skeletal metastases. Lincoln sign is previously described in monostotic Paget disease of the mandible and in contiguous spread of oral malignancy. We describe this pattern in distant metastatic involvement from carcinoma prostate with coexistent superscan pattern.
一位 70 岁男性因腺癌前列腺进行 Tc-亚甲基二膦酸盐闪烁扫描术分期。扫描显示骨骼系统弥漫性摄取增加，同时肾脏显影模糊，呈转移超级扫描模式。扫描还显示下颌骨体部摄取放射性示踪剂增加——林肯征或黑须征。影像学显示全身骨骼包括下颌骨均有硬化性病变，证实广泛的骨骼转移。林肯征先前被描述为下颌骨的单骨性帕哲病和口腔恶性肿瘤的连续性扩散。我们描述了这种模式在伴有超级扫描模式的远处转移性前列腺癌中的表现。
