Penile neoplasms are rare and can be primary or represent metastasis or local recurrence. the most common primary cancer of the penis is squamous cell carcinoma, accounting for 95 of all cancers. in spite of the rich vascularity of the organ, penile metastases are uncommon. Cutaneous metastasis of urothelial carcinoma (UC) is extremely rare and generally accepted as the late manifestation of a systemic spread. By 1998, approximately 500 cases of penile metastasis had been reported worldwide. However, only few case reports and series of fine-needle aspiration cytology (FNAC) of penile tumors have been documented. We report a case of penile metastasis from UC diagnosed by FNAC and describe the cytomorphological findings with an emphasis on cercariform cells. Although not commonly used, FNA of penile nodules can be effective in diagnosing recurrence or metastasis and avoiding surgical procedures, thus being an excellent initial procedure in the diagnostic approach.
