Adenosquamous carcinoma of the prostate is rare. Even rarer is the subsequent squamous metastasis or recurrence in which only the malignant squamous component is observed in some sites, with the adenocarcinoma present in other sites. We describe a case of squamous cell carcinoma presenting at the prostatic bed 6 years after radical retropubic prostatectomy was performed for adenocarcinoma. Even though the primary tumor showed adenocarcinoma with foci of squamous differentiation, there was no morphologic evidence of adenocarcinoma in the current tissue examined. The suspected origin of the squamous tumor from a recurrence of the prostate tumor is discussed.
前列腺腺鳞癌很罕见。更罕见的是随后出现的鳞状转移或复发，即在某些部位仅观察到恶性鳞状成分，而腺癌存在于其他部位。我们描述了一例在根治性耻骨后前列腺切除术后6年于前列腺床出现的鳞状细胞癌病例，该患者最初的肿瘤为腺癌且伴有鳞状分化灶，但在当前检查的组织中未发现腺癌的形态学证据。本文讨论了鳞状肿瘤疑似起源于前列腺肿瘤复发的情况。
