We report a case of transitional cell carcinoma of the urinary bladder metastatic to the penis. The diagnosis was established by fine needle aspiration biopsy (FNAB). Malignant cells showed mucinous differentiation. Ancillary studies carried out in the FNA material as well as in the primary bladder carcinoma suggested transitional cell carcinoma with mucinous differentiation. FNAB proved to be effective in diagnosing a secondary neoplasm to the penis. Mucoid differentiation of urothelial cells can be seen in FNAB specimens and might pose a problem in differential diagnosis.
我们报告一例膀胱移行细胞癌转移至阴茎的病例。诊断通过细针穿刺活检（FNAB）确定。恶性细胞显示黏液样分化。对FNA取材以及原发性膀胱癌进行的辅助检查提示为伴有黏液样分化的移行细胞癌。FNAB被证明在诊断阴茎继发性肿瘤方面是有效的。尿路上皮细胞的黏液样分化可见于FNAB标本中，可能会在鉴别诊断中造成问题。
