细针吸取细胞学诊断阴茎转移性直肠腺癌1例并文献复习

Penile metastasis from rectal adenocarcinoma diagnosed by fine-needle aspiration: a case report and literature review

目的:提高对阴茎转移性癌的认识及探讨阴茎肿块的诊断方法。方法:对1例阴茎硬结行细针吸取(fine-needle aspiration,FNA)操作及细胞学检查。结果:细胞学涂片见大量高柱状肿瘤细胞,部分细胞可见腺腔样排列,背景中见大量坏死,结合病史考虑阴茎转移性直肠腺癌。结论:阴茎转移性癌少见。其临床主要表现为阴茎硬结、异常勃起等。FNA检查安全、微创、高效、诊断准确,可作为诊断阴茎转移癌的首选方法。

Objective：To urge the awareness of penile metastatic carcinoma and to investigale Ihe procedures of diagnosing penile tumors. Methods： Fine -needle aspiration （FNA） cytology from the penile nodule was performed in one ease. Results： The smears showed a highly cellular aspirate consisting of columnar neoplastie cells which showed glandular pattern in some areas. Necrosis couht be appreciated all over the smears. Considering the histo~ of rectal adenocarcinoma, the cytological diagnosis was metastatic rectal adenocarcinoma of penile. Conclusion： Sec- ondary tumors of the penis are rare. The most frequent symptoms of seeonda~ tumors of the penis are nodule （s） and/or priapism. FNA is a safe, minimally invasive, effective, and highly accurate procedure in diagnosing penile lesions, and thus FNA can be the first choice for diagnostic approach to penile nodules.
