BACKGROUND
Paraneoplastic syndrome generally results from tumor-derived hormones or peptides that cause metabolic derangements. Common metabolic conditions include hyponatremia, hypercalcemia, hypoglycemia, and Cushing's syndrome. Herein, we report a very rare case of tongue carcinoma presenting with leukocytosis and hypercalcemia.
CASE PRESENTATION
A 57-year-old man was admitted to our hospital with tongue squamous cell carcinoma (cT4aN0M0, stage IV). He underwent radical resection following preoperative chemoradiotherapy, but locoregional recurrence was detected 2 months after surgery. He presented with marked leukocytosis and hypercalcemia with elevated serum levels of granulocyte colony-stimulating factor (G-CSF) and parathyroid hormone-related protein (PTHrP). He was therefore managed with intravenous fluids, furosemide, prednisolone, elcatonin, and pamidronate. However, the patient died 1 month later of carcinomatous pleuritis following distant metastasis to the lung. Immunohistochemical analyses of the resected specimens revealed positive staining for PTHrP and G-CSF in the cancer cells.
CONCLUSIONS
In this case, it was considered that tumor-derived G-CSF and PTHrP caused leukocytosis and hypercalcemia.
背景
副肿瘤综合征通常由肿瘤衍生的激素或肽引起代谢紊乱所致。常见的代谢状况包括低钠血症、高钙血症、低血糖症和库欣综合征。在此，我们报告一例非常罕见的舌癌病例，该病例表现为白细胞增多和高钙血症。
病例介绍
一名57岁男性因舌鳞状细胞癌（cT4aN0M0，IV期）入住我院。他在术前放化疗后接受了根治性切除术，但术后2个月检测到局部区域复发。他出现明显的白细胞增多和高钙血症，血清粒细胞集落刺激因子（G-CSF）和甲状旁腺激素相关蛋白（PTHrP）水平升高。因此，对他进行了静脉补液、呋塞米、泼尼松龙、降钙素和帕米膦酸治疗。然而，患者1个月后因肺癌远处转移导致癌性胸膜炎死亡。对切除标本的免疫组织化学分析显示癌细胞中PTHrP和G-CSF染色呈阳性。
结论
在本病例中，认为肿瘤衍生的G-CSF和PTHrP导致了白细胞增多和高钙血症。
