Benign
Condyloma acuminatum/anogenital wart
wart - papillary projection covered by hyperplastic squamous epithelium
wart - hyper and orthokeratosis, koilocytosis
wart -koilocytes
Preinvasive/precursor lesions - PENILE INTRAEPITHELIAL NEOPLASIA (PeIN)/ High grade squamous intraepithelial lesion (HGSIL)/Carcinoma in situ
Clinical presentations (variable)
HPV-related (oncogenic, high-risk types). Glans typically affected.
Bowenoid papulosis - transitional state between a genital wart and Bowen disease,
pigmented papules on the shaft, spontaneous regression, younger (30's-40's). Risk of progression 1%.
Bowen's disease - scaly hyperkeratotic plaque, usually on shaft of penis. Risk of progression 10%.
Erytroplasia of Queyrat - erythematous plaque on the glans and prepuce. Risk of progression 30%.
Erytroplakia - if microscopically PeIN than -> EQ
HPV-unrelated
Phimosis with leukoplakia of prepuce (whitish patch or plaque on the glans or prepuce)
Leukoplakia - clinical term (histologically from epithelial hyperplasia through PeIN to invasive carcinoma)
PATHOLOGY
PeIN, histopatho
WARTY OR BASALOID PEIN - HPV-related (particularly (HPV-16 and 18), looks like HGSIL in cervix
1.TRANSEPIDERMAL CYTOLOGICAL ATYPIA, 2.ABNORMAL PROLIFERATION, 3.ABNORMAL / LACK OF MATURATION
DIFFERENTIATED PEIN - not related to HPV
1. PARABASAL ATYPIA, 2. ABNORMAL BUT RELATIVELY PRESERVED MATURATION
Malignancy
Squamous cell carcinoma (95%)
0,5% of male cancers, >50yo
30-60% are HR-HPV related
HPV - RELATED TUMORS
Subtopic 1
SCC variants
Verrucous SCC - extremely well differentiated but large tumor with expansile growth; special subtype with good prognosis
Clinical&HP
Keratinising, usual SCC
Keratinising, usual SCC
Other possible skin tumors: melanoma, basal cell carcinoma, adenocarcinoma
