"Numerous therapeutic approaches can be employed, ranging from surgical and radiotherapeutic interventions for advanced cases, to chemotherapeutic agent administration for pre-malignant alterations (penile intraepithelial neoplasia (PeIN)) 3,25."

"When the diagnosis is confirmed, the lesion's depth of invasion is assessed along with vascular infiltration and the malignancy’s grade is estimated in accordance with the TNM system 2. Basaloid cell tumours (appearing “blue”) are usually HPV-positive, whereas those with “pink” cells (eosinophilic), which are mostly keratinised, are usually HPV-negative 16."

"usual type SCC (majority of cases; 48-65%)"
"Usual type SCC, demonstrates a variable mitotic activity, keratinisation, and the presence of epithelial pearl formations. If the malignancy is invasive, the basement membrane and surrounding structures are visibly infiltrated. Broder classification can be used to assess cellular differentiation considering nuclear pleomorphism, mitoses and keratinisation; this system defines SCCs as low-grade (grade I and II) lesions (well-differentiated with hyperkeratosis at the epidermis, from which atypical squamous cells emerge perpendicularly in cords, in 7 to 8 out of 10 patients) and high-grade (grade III and IV) lesions (metastases to surrounding regional lymph nodes and possible vascular and/or perineural invasion, in 2 to 3 out of 10 patients) 1."
"Markers have been shown to predict survival. Positive p53 is associated with a poor prognosis. Cyclin D1 and p21 do not seem to affect prognosis; however, p21 can improve model quality for survival prediction when incorporated into multivariable Cox models 20. Concerning invasive SCCs, p16 (INK4a) was found to be strongly correlated with good prognosis, excellent reproducibility, and increased cancer-specific survival (CSS) overall 21."
