BACKGROUND
Metastasis of transitional cell carcinoma (TCC) of the bladder to the skin and subcutaneous tissue is an uncommon finding.
CASE
A 58-year-old man with a known case of high grade TCC of the bladder, presented with a right paraspinal mass. Clinically an abscess was suspected. Fine needle aspiration (FNA) showed many clusters and isolated malignant cells in an inflammatory background. The smears were diagnosed as positive for malignancy.
CONCLUSION
It is essential to differentiate tumors metastatic to the skin and subcutaneous tissue from inflammatory lesions. FNA helped with the diagnosis in this case and prevented unnecessary biopsy.
背景
膀胱移行细胞癌（TCC）转移至皮肤和皮下组织是一种罕见的表现。
病例
一名58岁男性，已知患有高级别膀胱TCC，出现右椎旁肿块。临床上怀疑为脓肿。细针穿刺抽吸（FNA）显示在炎症背景中有许多细胞簇和孤立的恶性细胞。涂片诊断为恶性肿瘤阳性。
结论
将转移至皮肤和皮下组织的肿瘤与炎性病变区分开来至关重要。FNA在本病例中有助于诊断并避免了不必要的活检。
