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.
- Condyloma acuminata
- Precancerous conditions [3]
- 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
- 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
- Erythroplasia of Queyrat
- Grows on the glans and the prepuce
- Presents as a well-defined, red patch
- Undifferentiated PeIN
- Penile intraepithelial neoplasia (PeIN)
