疣状肿瘤约占阴茎鳞状细胞癌的三分之一,该肿瘤是一种低度恶性外生性乳头状肿瘤,罕见转移。隧道型癌,作为阴茎鳞状细胞癌的一种特殊亚型,其特征为肿瘤向深部组织穿透,生长方式类似于兔的洞穴。这种低级别疣状阴茎肿瘤类似于1954年Ayrd报道的跖肌穿掘性上皮瘤。隧道型癌也可发生 Verrucous tumors account for about one-third of penile squamous cell carcinomas, which are a low-grade, extraocular papillary tumor that rarely metastasizes. Tunnel cancer, as a special subtype of penile squamous cell carcinoma, is characterized by penetration of tumors into deep tissues in a manner similar to that of rabbits. This low-grade warty penile tumor resembles the plantar muscle-invasive xerodeoma reported in 1954 by Ayrd. Tunnel cancer can also occur
