Overview

Carcinoma of the penis must be differentiated from condyloma acuminata, penile intraepithelial neoplasia (PeIN), balanitis xerotica obliterans, buschke-Lowenstein tumour, bowenoid papulosis, and leukoplakia.

Differential Diagnosis

Carcinoma of the penis must be differentiated from:[1][2]

  • Noncancerous conditions
  • Condyloma acuminata
    • A common sexually transmitted disease caused by a virus belonging to the human papilloma virus (HPV) group
    • Lesions normally grow as a papilloma and are usually found on the glans, prepuce, or shaft of the penis
    • Lesions are benign, caused by low-risk HPV 6/11
    • Mixed infections with high-risk HPV types are relatively common
    • Progression to malignancy is rare.
  • Precancerous conditions
  • Penile intraepithelial neoplasia (PeIN)
    • most common precancerous condition of the penis
    • General term used to describe precancerous conditions of the penis that may develop into invasive squamous cell carcinoma (SCC) if they are not treated
    • Refers to abnormal cell changes, called carcinoma in situ, that occur on the skin surface of the penis
    • PeIN on the glans (head) or foreskin of the penis is also called erythroplasia of Queyrat
    • PeIN on the shaft of the penis is also called Bowen’s disease
  • Balanitis xerotica obliterans (BXO) also known as lichen sclerosis
    • A precancerous skin condition localized to the glans and the prepuce
    • Presents as white atrophic patches
    • The secondary development of phimosis inhibits washing and prevents early diagnostics of possible malignancy development on the glans or inside of the prepuce
    • A radical circumcision should therefore be performed for this disease
  • Buschke-Lowenstein tumour
  • Bowen's Disease
    • Undifferentiated PeIN
    • Manifests as a solitary, pigmented, scaly or scab-covered area
    • Affects the penis shaft, scrotum, perineum, and the suprapubic area
  • Bowenoid papulosis
    • Multiple, slightly elevated, red to violet or brownish papules, on the penis shaft and scrotum
    • Very rare, is preferably seen young men
    • May regress without treatment
    • Caused by high-risk HPV, most commonly HPV 16
    • Histologically cannot be separated from undifferentiated PeIN
  • Leukoplakia
    • Rare
    • Appear as a white hypertrophic or atrophic patch and usually occur secondary to chronic irritation
    • Develops in the meatus
    • Biopsy is necessary to exclude cancer and intraepithelial neoplasia (PeIN)
  • Erythroplasia of Queyrat
    • Grows on the glans and the prepuce
    • Presents as a well-defined, red patch
    • Undifferentiated PeIN
