Abstract

A 36-year-old woman with lung adenocarcinoma is reported. Chest X-ray film showed a high CT number, but no calcified lesion was detected. Histologic examination demonstrated no bone formation, calcification, or psammoma bodies. Calcium staining with Kossa method was negative. An elementary analysis with penetrating type electron microscopy and energy dispersion type analyzer showed high calcium concentration in the tumor. It was thought that the tumor showed a high CT number because of masked soluble calcium.

摘要

报道了一名36岁的肺腺癌女性患者。胸部X线片显示CT值较高，但未检测到钙化病变。组织学检查未发现骨形成、钙化或砂粒体。用科萨法进行钙染色为阴性。用穿透型电子显微镜和能量色散型分析仪进行的元素分析显示肿瘤中钙浓度较高。推测该肿瘤因可溶性钙被掩盖而显示出较高的CT值。
