  • HPV infection in about 50% of cases
Staging / staging classifications

Lowe staging (J Urol 1983;130:423):
A1:Localized to scrotum
A2:Locally extensive involving adjacent structures, including testis, spermatic cord, penis, pubic bone or perineum
B:Metastases to inguinal lymph nodes
C:Metastases to pelvic lymph nodes
D:Metastases to distant organs
Clinical features
  • Solitary, slow growing lesion and frequently ulcerated
  • Left side and anterolateral aspect of scrotum in occupational cases
  • Nodal metastases present in 50% of enlarged inguinal nodes
